ECPN Interviews: Electronic Media Conservation with Christine Frohnert

To promote awareness and a clearer understanding of different pathways into specializations that require particular training, The Emerging Conservation Professionals Network (ECPN) is conducting a series of interviews with conservation professionals in these specialties. We kicked off the series with Chinese and Japanese Painting conservation, and now we are focusing on Electronic Media Conservation (EMG). These conservators work with time-based media, which is characterized by artwork with durational elements, such as slide, film, and video, analog or born-digital materials, performance, light or kinetic art, sound or software-based art. We’ve asked our interviewees to share some thoughts about their career paths, which we hope will inspire new conservation professionals and provide valuable insight into these areas of our professional field.

In the first interviews for this series, we spoke with emerging conservators starting in the early stages of their careers working in time-based media, which included Alexandra Nichols, Nicholas Kaplan, Brian Castriota and Yasmin Desssem. In this interview, we hear from Christine Frohnert, a conservator who graduated in 2003 from the University of Arts in Berne, Switzerland, where she majored in the Conservation of Modern Materials and Media. Prior to establishing a private practice for Time-based Media (TBM) with colleague Reinhard Bek, Christine served as chief conservator at the Museum Ludwig in Cologne, Germany for twelve years and as chair of the AIC Electronic Media Group from 2008-2012. In 2012, she was named the inaugural Judith Praska Distinguished Visiting Professor in Conservation and Technical Studies at the Conservation Center at the Institute of Fine Arts, New York University (CC/IFA/NYU), where she now serves as the Time-based Media Art Conservation Curriculum Development Program Coordinator.

ECPN: Please tell us a little bit about yourself and your current position.

Christine Frohnert (CF): I am a conservator of contemporary art with a specific focus on technology-based art. Reinhard Bek and I founded Bek & Frohnert LLC in NYC in 2012- a conservation studio in private practice specializing in the conservation of time-based media (TBM). We are both German, have been trained in Europe, worked in leading positions in museums, and have been involved in international research projects.

Bek and I focus on the conservation of artworks with a durational element in our practice—such as sound, moving image, performance, light, or movement, that unfolds to the viewer over time via slide, film, video, software, or the internet. Since the studio’s inauguration, we have responded to individual needs for both TBM conservation treatments and consulting requests. However, over the last several years, we have experienced a rising demand to serve as consultants for different U.S. institutions without time-based media conservators on staff, as well as for collectors and artists. As many TBM art collecting institutions are facing rapidly increasing needs to adequately acquire, preserve, exhibit and store TBM works, we are responding to this development and our work is more geared towards long-term collection care and the development of preservation plans, as well as education.

ECPN: How were you first introduced to conservation, what contributed to your decision to specialize in time-based media, and why has been your training pathway?

CF: As with most of my colleagues, I started conservation being exposed to more traditional media such as paintings and sculpture. About 20 years ago, I realized that technology-based artworks can be seriously harmed or lost without a new conservation specialty being established. I became fascinated with TBM, and I learned about the newly established program ‘Conservation of Modern Materials and Media’ at the University of Arts, Berne, Switzerland. I graduated from there in 2003.

ECPN: Are there any particular skills that you feel are important or unique to your discipline?

CF: A complex range of skill sets are needed, which should be solidly grounded in the conceptual framework of contemporary art conservation as a whole. It requires knowledge in electrics/electronics and programming, and an in-depth understanding of each media category, technology and its preservation, documentation and digital preservation needs. As our profession is highly collaborative by nature, soft skills are equally important to collaborate with all the stakeholders in the institutions involved, as well as with affiliated external professionals such as engineers, computer scientists, and technicians. This is important when defining, communicating, and verifying goals with vendors.

As many museums recently formed or are currently forming ‘Media Teams’ in their respective institutions to tackle their individual TBM collections needs, we have witnessed a rapidly increasing need for skilled labor, dedicated TBM lab space, equipment, and the trustworthy storage and management of huge amounts of born-digital or digitized artworks.

ECPN: What are some of your current projects, research, or interests?

CF: Currently our recent projects include consultation with several institutions to analyze their TBM collections and develop custom-designed conservation strategies according to their individual collections needs and skill sets of staff. These consultations may include surveys, assistance with media acquisitions, exhibitions and artwork documentation, storage, and migration. Bringing in external expertise often provides the bridge that many museums and their TBM stakeholders do not find in-house or do not have the capacity to coordinate. This work helps to identify and structure these needs more clearly and often provides the basis for institutional development and the implementation of larger collection care projects.

Recent and current treatment-based activities range from analyzing the ‘mechanical’ programming of a light-based work, the conservation of a seven channel-video wall from 1998 consisting of 207 Cathode Ray Tube monitors, digitization of analog video, and the reverse engineering of custom-designed large format slide projectors, to name a few.

ECPN: In your opinion, what is an important need in your specialization?

CF: the most pressing need is education. Technology-based art is considered to be very sensitive to damage, loss, misinterpretation, and incorrect installation, due to its very specific and sensitive relationship to time, space, and concept. Damage or loss of a TBM work cannot be seen by simply examining the physical material and may not be immediately apparent unless the individual has received specialized training.

TBM conservation has been identified as a priority by many museums, collectors, and funding agencies. However, the educational opportunities are still limited, and there is currently no U.S. graduate program offering a degree in this specialty (but this will change soon!). As a result, a huge amount of our most recent cultural heritage is at risk, in an unknown condition, and/or not sufficiently integrated into museums’ missions of collecting, exhibition, conservation, research, and education.

However, thanks to the generous funding provided by the Andrew W. Mellon Foundation, the Conservation Center at the Institute of Fine Arts, NYU, started the TBM art conservation curriculum planning project in 2016.The new TBM specialization will be integrated within its current curriculum starting in fall 2018. This will be the first conservation program offering this specialty in the U.S. and the graduates will receive a dual degree: an MS in the Conservation of Historic and Artistic Works and an MA in the History of Art and Archaeology.

ECPN: Have you been involved in any advocacy, outreach, teaching or professional service roles in your specialization?

CF: During my time as EMG (Electronic Media Group) board Chair from 2008-2012, we received numerous request from the membership to offer continuing education opportunities, and in response EMG launched the conference series entitled TechFocus in 2010. The series is designed to provide hands-on guidance and systematic education on different media categories (TechFocus I: Caring for Video Art, Guggenheim Museum, NY, in 2010; TechFocus II: Caring for Film and Slide Art, Hirshhorn Museum and Sculpture Garden, Washington, DC, 2012; TechFocus III: Caring for Software-based Art, Guggenheim Museum, NY, in 2015). In addition, the first periodical worldwide that focuses on TBM art conservation was launched by the EMG in 2012, The Electronic Media Review.

At the (CC/IFA/NYU) I have offered instruction in TBM conservation art in different capacities, including the course Art With A Plug: The Conservation of Artwork Containing Motion, Sound, Light, Moving Images and Interactivity (Fall 2012 and Spring 2015).

Several professional organizations and initiatives have created additional targeted educational opportunities and collaborations. However, despite all these good developments, further training is needed at the graduate level, as well as in continuing education for professionals, to address the fast-increasing demands of TBM conservation.

Under the leadership of Dr. Hannelore Roemich, Professor of Conservation Science and TBM program Director, I have also served as TBM Program Coordinator to assist in identifying skill sets and core competencies of TBM conservators that translate into the educational needs to develop a TBM curriculum. In the fall of 2016 the Conservation Center offered the course and public lecture series Topics in Time-based Media Art Conservation, which included ten lectures by leading art historians, artists, computer scientists, and conservators. These events were an important outreach component of the curriculum development project, and they created the opportunity to promote the field, foster the dialogue between TBM professionals, and build a community.

We are now organizing the upcoming symposium It’s About Time! Building a New Discipline: Time-based Media Art Conservation to be held in May 2018. The two-day symposium will provide a forum for educators, artists, art historians, museum curators and directors, collectors, gallerists, engineers, computer scientists, and conservators to promote TBM art conservation as a discipline on an international level and will conclude the TBM curriculum planning phase.

ECPN: Do you have any advice for prospective emerging conservators who would like to pursue this specialization?

CF: While I am not comfortable issuing general advice, I can say that I personally appreciate working with students and colleagues in our field, and that this has shaped and enriched my professional life. If you are a strong communicator who is interested in the intersection of art and technology, art conservation, and art history– and maybe you even have a background in one or more of the related media fields–why don’t you join the EMG sessions at the AIC annual meetings and/or attend the upcoming NYU symposium to engage with the TBM community and find out if this specialty may be just the right fit for you?

ECPN: Please share any last thoughts or reflections.

CF: We currently see an extremely high demand for trained TBM conservators. This can be measured by the exponentially increasing job offers worldwide and the challenges many institutions face to find qualified candidates. So, it is safe to say that this is the best moment in time for becoming a TBM conservator in this country.

ECPN Interviews: Electronic Media Conservation with Yasmin Dessem

To promote awareness and a clearer understanding of different pathways into specializations that require particular training, the Emerging Conservation Professionals Network (ECPN) is conducting a series of interviews with conservation professionals in these specialties. We kicked off the series with Chinese and Japanese painting conservation, and now we are focusing on practitioners in AIC’s Electronic Media Group (EMG). These conservators work with time-based media, which can include moving components, performance, light or sound elements, film and video, analog or born-digital materials. We’ve asked our interviewees to share some thoughts about their career paths, which we hope will inspire new conservation professionals and provide valuable insight into these areas of our professional field.

This is the third post from ECPN’s EMG blog series, for which we first interview Nick Kaplan and more recently, Alex Nichols. For our third interview from the EMG series, we spoke with Yasmin Dessem, currently Head of the Audiovisual Preservation Studio at UCLA Library where she serves as the technical lead as the library continues to develop its program of preservation, digitization and access of its moving image and sound holdings. Previously she managed archive deliverables for new feature releases at Paramount Pictures. She has experience working with a wide variety of moving image and sound formats, as well as pre-film animation devices, silent-era cameras, costumes and paper collections. Yasmin holds Master’s degrees in Art History and Moving Image Archive Studies from UCLA.

ECPN: Please tell us a little bit about yourself and your current position.

Yasmin Dessem (YD): I oversee the preservation of moving image and recorded sound materials at the UCLA Library’s Preservation Department. For nearly 90 years, the UCLA Library has collected audiovisual materials with content such as home movies, oral histories, and radio broadcasts. Examples are home movies of Susan Sontag’s parents sailing to China in the 1920s and field interviews with Watts residents after the 1965 riots. Audiovisual preservation (AV) at the library is a relatively young unit—a dedicated AV preservationist first came on board in 2011. We offer a number of in-house digitization and preservation services and are currently focusing on increasing our capacity and launching a survey.

ECPN: How were you first introduced to conservation, and why did you decide to pursue conservation?

YD: The 1996 re-release of the restored version of Vertigo first made me aware of film restoration and preservation as an actual practice. Later, as I was finishing my Masters in Art History at UCLA, I took a wonderful class on restoration, preservation, and conservation with Professor David A. Scott. The course covered the material care issues and decision-making ethics for a wide breadth of cultural heritage materials. The class struck a deep chord with me, but I was eager to graduate and start working. After graduation, I ended up working in the film industry for about six years. I was tracking down historic stock footage at one job when my mind circled back to the preservation field as I considered how the films were stored and made available. I had entertained the idea of potentially returning to graduate school to study art conservation some day, but around that time the idea of film preservation as a possible career path began to fully materialize for me. As a result, I began exploring potential graduate programs.

ECPN: Of all specializations, what contributed to your decision to pursue electronic media conservation?

YD: My longtime love for film and music intersected with my curiosity for all things historical and technology-related. These were topics that in one form or another always interested me, but I don’t think I had a full grasp on how to combine them meaningfully into a profession. Preservation was the missing key. My exposure to preservation and conservation while studying art history and my later experience working at film studios both helped direct me towards the specialization.

ECPN: What has been your training pathway? Please list any universities, apprenticeships, technical experience, and any related jobs or hobbies.

YD: I pursued my studies in the Moving Image Archive Studies (MIAS) Program at UCLA—which persists today as a Master of Library and Information Science (M.L.I.S.) with a Media Archival Studies specialization. While in the program, I completed internships with Universal Pictures and the Academy of Motion Pictures Arts and Sciences, and volunteered at the Hugh Hefner Moving Image Archive at the University of Southern California. Throughout the two-year MIAS program, I also worked as a fellow at the Center for Primary Research and Training program at UCLA Library Special Collections, where I learned archival processing. My experiences weren’t limited to preserving moving image and sound media, but included paper-based collections, costumes, and film technology. After graduating I attended the International Federation of Film Archives (FIAF) Film Restoration Summer School hosted by the Cineteca di Bologna and L’Immagine Ritrovata.

ECPN: Are there any particular skills that you feel are important or unique to your discipline?

YD: Digital preservation will continue to be a key area of expertise that’s needed in museums and archives. Preserving the original source material and digitizing content is not enough. There are more resources than ever for strategies and tools for digital preservation, and it’s important to seek them out. Another valuable skill is developing a level of comfort with handling and understanding the unique characteristics of a wide variety of physical analog formats such as film, videotape, audiotape, and grooved media (LP, 78s, lacquer discs, wax cylinders, etc.). Similarly, it’s helpful to have a familiarity with playback devices for these obsolete media formats (equipment like open-reel decks or video decks.) Lastly, metadata can be an unsung hero in media preservation. Often, we’re the first to see or hear a recording in decades, so capturing metadata around the point of transfer is critical. Metadata standards can be a rabbit hole of complexities, especially when it comes to describing audiovisual media, but understanding their application is an essential skill.

ECPN: What are some of your current projects, research, or interests?

YD: We’re just wrapping up digitization of materials from the Golden State Mutual Life Insurance Company (GSM), an African American-owned and operated insurance firm established in Los Angeles in 1925 in response to discriminatory practices that restricted the ability of African American residents to purchase insurance. GSM operated for 85 years and their collection is a vibrant resource documenting Los Angeles and the empowerment of a community. We received grants from the National Film Preservation Foundation and the John Randolph Haynes and Dora Haynes Foundation to support this work. The digitized collection is now available on Calisphere. We’ve just started a crowd sourcing project working with former GSM staffers to describe any unidentified content. It’s been one of the most rewarding experiences of my career, hearing everyone’s stories and seeing how much it means to everyone involved to have this collection preserved and made available.

We’ve also been in preparation to launch a large-scale survey that will help us gather data on the Library’s audiovisual collections that can be used for long term-planning. Outside of UCLA, we’ve been involved with ongoing work with cultural heritage institutions in Cuba. Last February, I set up equipment and held a workshop on the digitization of radio transcription discs held at the Instituto de Historia de Cuba (IHC) in Havana. I’m heading back there next week to begin a project to transfer IHC’s open reel audio collections.

ECPN: In your opinion, what is an important research area or need in your specialization?

YD: It’s crucial to preserve the expertise related to the operation and repair of playback equipment. Playback equipment will become more and more difficult to source in the future. Engineers, whose entire careers are dedicated to the use and care of this equipment, are some of the best resources for this knowledge. Their knowledge is shared through conversation, YouTube videos, social media, and professional workshops. Documenting the skills required to handle, maintain, calibrate, and service this equipment in a more formalized way and sharing that knowledge widely will ensure that the preservationists can keep their equipment viable for longer.

ECPN: Do you have any advice for prospective emerging conservators who would like to pursue this specialization?

YD: Try everything. Media preservation requires a wide variety of skills from computer coding to soldering decades-old circuit boards. Depending on where your career takes you, it’s good to have at least a passing familiarity with the full range of skills you may need to call upon. Apply for internships or fellowships with organizations, like the National Digital Stewardship Residency. Volunteer at community-based archives that need help getting their collections in order. Join professional organizations, like the Association of Recorded Sound Collections (ARSC) or the Association of Moving Image Archivists. Attend conferences like code4lib, the Preservation and Archiving Special Interest Group (PASIG), or the Digital Asset Symposium (DAS). Network with engineers or preservation professionals to continue to grow your own expertise, but also share your own skills when you can. Collaboration and knowledge-sharing are a fundamental part of the profession.

ECPN: Please share any last thoughts or reflections.

YD: One thing to be aware of, if you’re a woman in the field of audiovisual preservation, is that you may occasionally run into people who are surprised to see a woman working with technology (much less wielding a screwdriver!). This response persists to some degree despite the presence of many successful female professionals in the field. What’s encouraging, however, is seeing the growth of groups like the Women in Recorded Sound collective at ARSC providing support.

Audiovisual preservation is such a gratifying profession. Having the opportunity to make historic content available is incredibly meaningful work that I feel lucky to be a part of everyday. On an even more basic level, figuring out a new workflow or getting a piece of equipment to finally work is just so viscerally satisfying. I’m part of an amazing team whose passion, humor and willingness to try out new things inspires me every day and makes me feel so lucky to be doing this work.

ECPN Interviews: Electronic Media Conservation with Alexandra Nichols

In our first EMG interview, we spoke with Nick Kaplan. Now for our second interview from the EMG series, we turn to with Alexandra Nichols, currently a Sherman Fairchild Foundation Fellow in the conservation of time-based media and installation art at The Metropolitan Museum of Art. From 2016-2017, she was a Samuel H. Kress Foundation Fellow in Time-based Media Conservation at the Solomon R. Guggenheim Museum. She earned her Master’s of Art Conservation from the Winterthur/University of Delaware Program in Art Conservation (2016) where she concentrated on the conservation of modern and contemporary objects.

ECPN: Please tell us a little bit about yourself.

Alexandra Nichols (AN): I received my Master’s of Conservation from Winterthur/University of Delaware Program in Art Conservation in 2016, where I concentrated on the conservation of modern and contemporary objects. I recently completed a one-year fellowship as a Samuel H. Kress Foundation Fellow in Time-based Media Conservation at the Solomon R. Guggenheim Museum, where I was working under Joanna Phillips, the Guggenheim’s Senior Conservator of Time-based Media. Just a few weeks ago, I joined the Metropolitan Museum of Art as a Sherman Fairchild Foundation Conservation Fellow, where I’ll be working with the Met’s collection of time-based media and installation art.

ECPN: How were you first introduced to conservation, and why did you decide to pursue conservation?

AN: After obtaining my undergraduate degree in art history, I moved to London and landed a job as an executive assistant at the British Museum. While there, I visited the Hirayama Studio, the British Museum’s conservation lab dedicated to the care and treatment of East Asian paintings and works on paper. It’s a beautiful, peaceful room, with tatami mats and walls lined with brushes and different types of paper. I loved how the conservators could develop such a close, tactile relationship with the artworks, and how the treatments were carried out with respect for the cultures that created the works. This led me to seek out internships where I could gain experience in conservation.

ECPN: Of all specializations, what contributed to your decision to pursue electronic or time-based media conservation?

AN: I’m really fascinated by the wide range of materials and methods utilized by contemporary artists. Something I love about time-based media art is its complexity and variability. An artwork may have multiple channels of video, require a very specific placement in the gallery, or be shown differently based on the size or shape of the room.

My training is in objects conservation, focusing on the conservation of contemporary art. During the course of my graduate studies, none of the North American programs offered coursework in time-based media*. Thus, I was able to explore working with time-based media during my graduate internships at the Hirshhorn and the Museum of Modern Art. I’ve been pleasantly surprised that many of the time-based media pieces I’ve worked on incorporate sculptural elements, so my graduate training has been helpful in ways I didn’t expect. Learning how these objects should be placed in an installation and their relationship to electronic and audiovisual elements is really intriguing.

ECPN: What has been your training pathway? Please list any universities, apprenticeships, technical experience, and any related jobs or hobbies.

AN: I’ve always had an interest in computers and electronics. In middle school and high school, I learned the programming language C, built computers as a hobby, and took courses in video editing and digital photography as part of my undergraduate degree.

I’m originally from the Washington, DC area, and after deciding to pursue conservation, I completed pre-program internships and contracts at various museums in the Smithsonian system, including the Freer and Sackler Galleries, the Museum Conservation Institute, and the National Museum of African-American History and Culture.

In 2013, I began my graduate studies at the Winterthur/University of Delaware Program in Art Conservation, where I specialized in the conservation of modern and contemporary objects. As a graduate student, I completed a summer internship at the Hirshhorn Museum and Sculpture Garden, preparing time-based media works in their collection for the 2014 exhibition Days of Endless Time. During my third-year internship at the Museum of Modern Art in New York, I collaborated with Kate Lewis and Amy Brost to treat a pearlescent bead-adorned cathode ray tube television set by Nam June Paik and Otto Piene.

Additionally, the chance to work with Joanna Phillips at the Guggenheim has been thrilling—there aren’t many opportunities to learn about time-based media conservation in the American graduate conservation programs, so emerging conservators must gain expertise through internships and fellowships. However, this is changing soon — The Institute of Fine Arts (IFA) at New York University is implementing a curriculum geared towards the conservation of time-based media, and is accepting applications this year for Fall 2018 matriculation (link: https://www.nyu.edu/gsas/dept/fineart/conservation/time-based-media.htm). I’ll be utilizing the skills I’ve developed over the past year at my current fellowship working with the time-based media art collection at The Metropolitan Museum of Art.

ECPN: Are there any particular skills that you feel are important or unique to your discipline?

AN: Strong documentation skills are important in any specialization, but this is especially true for time-based media. The inherent variability of time-based media requires extensive research and documentation to ensure that it can be installed correctly in the future. It’s also important to know about the history of video production, including film history and the development of various formats. Foundational knowledge of video and other technologies is also crucial and has to be updated continuously, since technology is always evolving. Without this knowledge, media conservators cannot seek out and engage external specialists and vendors who can provide specific technical expertise

ECPN: What are some of your current projects, research, or interests?

AN: I am just getting started at The Met, but I am currently working with Nora Kennedy and Meredith Reiss to help document the 250 time-based media artworks in The Met’s collection. This includes updating questionnaires that are sent to artists during the acquisition process, which help us learn more about the production history and intended exhibition of the artwork, and researching past exhibitions to create retroactive iteration reports. The Met has had a Time-based Media Working Group for many years now, and I am looking forward to collaborating with its members as I conduct my research.

ECPN: In your opinion, what is an important research area or need in your specialization?

AN: I think the acquisition and display of virtual reality (VR) will pose a number of challenges for conservators in the coming years. Artists are increasingly experimenting with these types of works—Jordan Wolfson exhibited a VR work in the Whitney Biennial this year, for example—but as far as I know, no museums have acquired a VR piece yet. This technology is so new and is still being developed, and as a result, there’s so much potential for the obsolescence of file formats and hardware.

ECPN: Do you have any advice for prospective emerging conservators who would like to pursue this specialization?

AN: Try playing around with how to shoot and edit your own video in Final Cut Pro or Premiere! It will teach you about digital video formats and give you some insight into the artist’s process. And, don’t be afraid to reach out to conservators you admire to learn more about what they do!

ECPN: Please share any last thoughts or reflections.

AN: Supervised training under established media conservators is essential to the development of one’s skills as an emerging time-based media conservator. Fellowships and internships provide practical experience with real-life museum scenarios that is not possible to gain through readings or coursework. I am extremely grateful to the Samuel H. Kress Foundation and the Sherman Fairchild Foundation for providing me with opportunities to hone my expertise at the Guggenheim and The Met.

43rd Annual Meeting – Architecture Specialty Group – May 16, Mid-Century Modern Wood Issues at the Weston Havens House by Kitty Vieth and Molly Lambert

Kitty Vieth, a senior associate at Architectural Resources Group, presented the work required to rehabilitate the most fragile structural conditions of the Weston Havens House. Molly Lambert, a conservator in private practice, discussed techniques she used to remove tide lines from interior cedar paneled walls.
The Weston Havens House is a Mid-Century Modern construction designed by architect Harwell Harris and built in 1941. It sits in the hills of Berkeley and has an 180-degree view of the San Francisco Bay. Weston Havens was the only owner of the house until his death in 2001. He bequeathed the property to the University of California Berkeley who now uses the house for visitors.
The house features a modernist design with upper and lower levels cut into a hillside. A curvilinear stair leads to the lower floors. There are two guest rooms with private terraces. The house contains original finishes at are intact. Kitty Vieth was brought in to evaluate the conditions of the materials and all building systems.
Upon evaluation, two high priority projects were defined. The first project was the Pedestrian Bridge that was in a state of near collapse. The bridge displayed a keel type construction with paired studs. Slow growth Redwood found in the Berkeley area was used to construct the Bridge. All of the wood showed deterioration, especially the structural components. Fortunately, the main beams were still structurally sound, but Vieth was not able to save the rafters and studs. The bridge was reconstructed using long slow growth of redwood that is already beginning to fade to grey and better match the original materials. A finish was used to protect the reconstructed bridge.
The second priority was the East wall and roof area. The seismic activity of the area was considered. Redwood boards were greyed, worn and cupping in some locations. Vieth consolidated and rehabilitated the windows and walls on East wall.
Molly Lambert spoke next about earlier work she undertook in the house when Weston Havens was still alive. This and other modernist structures often have redwood paneled interiors. When roofs leak tide lines form on the interior panels. Molly did two different campaigns to repair tannin tide lines on the interior of this house. She was able to get 80-90% of the tide lines out. Tannins in the wood migrate with water causing the darkened lines.
Her technique was as follows:

Wipe down the entire panel with wet cotton PVOH sponges (cellulose sponges) with grain.
Harvest some of the tannins with a swab using distilled water or spit and transfer to needed areas.
Don’t take too much of the tannins away.
In-paint with a tannic acid mixture as needed.

42nd Annual Meeting – Joint Architecture and Objects Session, May 29, "The Cultural Production of Tourism at Lake Tahoe: Exploring How Cultural Heritage Preservation Is Impacted By Tourism," by Catherine Magee

This paper was a departure for a specialty group presentation in that it focused not on the conservation or technical study of material culture, but on the creation and consumption of cultural narratives and landscapes. Magee noted that conservation work informs and perpetuates stories about people, places, and things, and made the point that conservators are generally comfortable thinking about our work in the context of education, science, and academic scholarship. But she proposed the idea that we must also consider our role in the broader context of tourism, since the primary products of our work – conserved objects and sites – are most often intended for consumption by the general public, also known as tourists.
Her paper included a brief overview of tourism studies, examining the impact of tourism on different kinds of sustainability: economic, ecological, and cultural. The bulk of the paper was spent illustrating the latter point, looking at the ways tourism influences our perception of history and heritage by creating hybrid tourist/cultural heritage landscapes and influencing cultural memory.
Magee used two examples from her doctoral research, which focuses on the landscapes and material culture of the Washoe people in the Lake Tahoe area. The first example was Cave Rock, a pilgrimage site of major spiritual significance for the Washoe. The site was progressively destroyed by tourism, evolving from a culturally significant tourism site, to a pathway for a road, to a mecca for rock climbers. The second example focused on an iconic Washoe basket form, the degikup, and its most famous creator, Dat-So-La-lee. Magee examined the shared mythos of Dat-So-La-Lee and the degikup in detail, revealing the stories, and the basket form itself, to be products created for tourism.
The role of the conservator in shaping the destiny of a site like Cave Rock or the narrative surrounding iconic artifacts and artists like the degikup and Dat-So-La-Lee was not explicitly discussed. It’s not difficult, however, to imagine the complexity inherent in conservation decision-making for the kinds of tourist-hybridized sites, objects, and narratives explored in this paper. Magee argued that we conservators will discharge our responsibilities best if we develop a better awareness of our role in the cultural production of tourism. With that awareness, we can improve our agency in the process and generate better outcomes for sites, objects, and the communities we serve.

41st Annual Meeting – Architecture Session, May 30, “Fifteen Shades of Grey…? Paint Color Analysis on the Eames House,” by Emily MacDonald-Korth, Alan Phenix, Tom Learner, and Kyle Normandin

The Eames house was designed in 1949 by Charles and Ray Eames as the eighth house in the case study house program of the Arts & Architecture magazine. The Eames lived in the home until their deaths; after 1988 the house remained untouched. In 2011, the contents of the living room were reassembled at the Los Angeles County Museum of Art (LACMA) for an exhibition. It was at this time that the Getty Conservation Institute (GCI) provided investigation and scientific analysis to determine the conservation issues and plans for the house. The 2011-2012 initiative of the Eames House conservation program was to determine the paint stratigraphy of the interior and exterior of the home. This presentation discussed the approach, technology used, sample extraction, and findings for the Eames House investigation.

The study included 15 samples and 6 in-situ investigations from the interior and exterior of the house. In on-site storage, the team located painted plates and several date labeled paint cans that were used for comparison. The team deployed the use of optical microscopy, EDS cross-sectional photo, micrographs, and stratigraphic examination in order to identify the layers of paint present. It was noted that the limited number of samples may not represent all of the paint layers present, for this reason cross-sectional and in-situ excavation were used in conjunction of each other to cross reference findings.

Interior, Eames House, Case Study House No. 8. Designed by Charles and Ray Eames, 1949.

To begin the study, the team identified the known timeline of painting campaigns, for this they relied on historical documentation. The following was known about the house:

1949-House built
1978-Charles’ death
1978-repair campaign
1988-Ray’s death
1989-painting campaign
1994-painting repair
2003-painting campaign
The house & studio show similar paint layers, but the interiors differ

Initial comparison of exterior cross-section and excavation indicate that the two areas have similar stratigraphy. When in comparison, they were able to loosely date the layers to the appropriate painting campaigns. Paint extractions were then separated by paint layers and material composition. The team was able to determine that the earlier paint layers were mixed through subtractive color mixing; this type of mixing technology indicates that great care went into the color mixing and selection process.

Primer layers show that a warm grey was the first layer, with no evidence of dirt between the layers. At this time it was hypothesized that the exterior color was changed to black from 1978-1988. The paint analysis showed a series of gray paints with compositional overlap and two zinc based primer layers. Most samples have two layers below the zinc primer that are the same in composition to the exterior first two layers. Based on these results, it was determined that the first generation warm gray layer exists on the interior and exterior of the house.

AIC's 41st Annual Meeting – Architecture Session, May 30, “Bringing Modern Back: restoring 1930s Aluminum Finishes,” by Helen M. Thomas-Haney and Xsusha Flandro

Pre-Restoration, 4th Avenue Station, Brooklyn, New York — Aluminum spandrel before restoration.

Helen M. Thomas-Haney and Xsusha Flandro discussed their research and investigation of restoring aluminum finishes at a train station. Discovered in 1825 by Hans Christian Oersted, aluminum was used in jewelry and decorations into the mid-nineteenth century. The first architectural use of aluminum in the United States was for the cap of the Washington Monument in 1884. As production increased and price decreased, aluminum began to be more widely used in commercially available products. By the 1920s, aluminum was being used on many buildings in Vienna, in modernist movement buildings, and on the Empire State Building. Companies such as ALCOA Aluminum advertised aluminum as weather resistant and structurally sound. It’s ease of being manipulated made aluminum popular as decorative ornamentation on exteriors, but also in Art Deco interiors.

Post-Restoration, 4th Avenue Station, Brooklyn, New York — Artistic rendering of aluminum spandrel, post-restoration.

Built in 1932, the train station was constructed of a copper roof, pine ceiling, and aluminum arch spandrels. The station had alterations over the years, including lead paint, the addition of billboards that pierced the aluminum panels, and graffiti. The conservation project began with research into project specifications, original drawings, and original finish specifications. Through research and material evidence, it was clear that the aluminum spandrels had three different types of mechanical finishes. Based on the historical terminology, these were identified as “satin”, “sand-blasted”, and “sand-blasted deplated”. The station remained in service during the restoration, so precautions were taken during paint removal and repair work. After the paint was removed, two different types of corrosion were revealed. Corrosion was especially significant in areas where the differing materials joined. Based on the containment issues caused by sandblasting to remove corrosion, other means of removal were necessary. Some corroded areas were patched and repaired, while other panels were taken offsite for restoration.

After surface preparation, the finishes were recreated in-situ. The “satin” finish was recreated by hand sanding with a coating to prevent corrosion. Initially, a bristle-blaster was used for the “sand-blasted” finish, but it did not complete the desired effect. The team later used aluminum oxide blasting for the finish. The “sand-blasted deplated” finish was completed with an aluminum patination process with a black patina buffed to gray.

AIC’s 39th Annual Meeting – ASG Session, June 3, “Conserving a Space for Commemoration: Trinity Cathedral Burial Ground Renewal” by Teresa Duff, Post-Graduate Fellow, University of Pennsylvania’s Graduate Program in Historic Preservation

Teresa Duff presented the conclusion of a twenty-year, three-phased conservation project by the University of Pennsylvania Graduate Program in Historic Preservation at the Trinity Burial Ground in Pittsburgh, PA. The first phase, begun in 1990, entailed a condition survey and pilot testing program for the conservation of grave markers in the cemetery. In 2000, students from the University of Pennsylvania performed the second phase of testing, and in 2007-2008, Duff and her colleagues began Phase 3, which was in conjunction with a landscape renewal by Andropogon.

Duff explained that the site was a Native American burial ground that was adopted by white settlers in 1779. In 1822 the first church was erected on the site, and the current Trinity Cathedral was constructed in 1872. The grounds contain 155 stones along with burial-marker fragments. Duff and her colleagues mapped the site and numbered each plot, and created color-coded layers for conditions, treatments and the history of markers. They built a site-specific treatment platform for the on-site conservation of markers, and completed the conservation treatments begun in 2000. Treatments included cleaning and removal of biological growth, epoxy repairs for blind delamination and cracks, pinning with fiberglass pins, carbon fiber strap reinforcement on the back of some markers, excavation and resetting of partially buried or at-risk markers, and the burial of markers who had lost their material integrity. Fragments were displayed on the exterior walls of the church.

The author provided detailed information about treatments and products, but I would have liked to have learned more about the history of the site, the types of stones and carving represented in the burial ground, and the rationale behind some of the treatments. There were many questions following the talk about the landscape renewal by Andropogon, particularly the native grass they selected which does not need to be mowed. It was a well-organized presentation with good visuals and detailed information.

39th Annual Meeting – Architecture Session, June 3, “Assessment and Characterization of the Architectural Metal Finishes at Fort Moultrie: A Successful Student-Scientist Collaboration” by Stéphanie A. Cretté, Lisa M. Nasanen and Néstor G. González-Pereyra, Clemson Conservation Center, Warren Lasch Laboratory; and Frances H. Ford, Clemson University/College of Charleston Graduate Program in Historic Preservation

Amelia Millar from the Clemson University/College of Charleston Program in Historic Preservation, and Stéphanie A. Cretté from the Clemson Conservation Center presented a two-part paper on a graduate-level project at Fort Moultrie National Monument near Charleston, SC. Millar presented the student portion of the work, while Cretté presented the analytical research.

The project entailed a survey of metals in a portion of the Fort Moultrie site, owned by the National Park Service. Students from the Clemson University/College of Charleston program performed a survey of all existing metals, both architectural metals and the metal objects on site, and assessed the condition of the metals. They took paint samples to determine the chemical composition of the paint so that NPS can develop a strategy to safely remove any lead-containing paint while preserving the metal substrates. The students did most of the field work and tested paint-removal methods, then collaborated with scientists from the Clemson Conservation Center on SEM-EDS and Raman analysis of the paints. Most of the scientific portion of the presentation was about the analytical techniques and why they were used for this application.

The paper was interesting, but I would have liked to have learned more about the researchers’ findings and the various treatment recommendations put forward by the students. It would have also been interesting to learn whether the NPS has implemented or plans to implement any of the student recommendations. Nevertheless, it was a good collaborative project that seems to have benefited the students and scientists alike.

39th Annual Meeting – Architecture Session, June 3, “Comparative Study of Commercially Available Rust Converters” by Jason Church, Anna Muto and Mary F. Striegel, National Center for Preservation Technology and Training

Jason Church from NCPTT presented a useful paper on commercially available rust converters. He explained that rust converters are a chemical treatment that converts iron oxide into a more stable product, though this product varies depending on the chemical composition of the rust converter. Church and his colleagues started with the 1995 Canadian Conservation Institute study of rust converters, but found most of the products to have been discontinued or available in new formulations. This led the team to perform their own experiment.

Church et al., selected four commercial products of varying chemical composition: Ospho (phosphoric acid base), Rust-oleum Rust Reformer (tannic acid base), Corroseal (gallic acid base) and RCx427 (oxalic acid base). The four commercial products were selected on the grounds that these products were readily available, were top sellers, and could be purchased in sufficiently small quantities so as to be accessible to homeowners or for small conservation projects. Church and his colleagues also tested the CCI-recommended custom formulation of tannic and phosphoric acid, which several objects conservators they polled still claim to use. NCPTT staff tested the five rust converters on new A36 carbon steel that was naturally weathered. They subjected each of the test samples to artificial weathering and measured the samples for color changes and active corrosion every 250 hours for 1000 hours total. They found that the Rust-oleum product had the least color change and most stable surface of the five products tested, though the efficacy of each product tested was quite varied. Church mentioned that their testing is not complete. They continue to push the Rust-oleum product to metal failure through extended artificial weathering, and will also test the new aerosol version of that product. They also plan to perform outdoor accelerated weathering tests on the five products.

The presentation was interesting and informative, as is characteristic of studies done by NCPTT. I like that their experiments are developed for conservators, but the results are accessible to anyone. The information presented in this talk will surely broaden the body of knowledge for architecture and objects conservators and will be useful for homeowners and maintenance workers. Following the talk, moderator Patty Miller recommended that they eventually expand their testing scope to include conservation-grade products and less readily available materials. I concur, and I would encourage Church and his colleagues to publish their findings.
