Object Conservator Céline Chrétien described her experiences working with contemporary artist Richard Fauguet to conserve his piece Mirida and her more recent work with Buddhist monks to conserve actively-used liturgical objects. Though on the surface these projects seem very different, they both raised interesting questions about how to apply conservation ethics to situations in which the artist – or, in the case of the liturgical objects, the believers – still have a living relationship with their objects.
While working at the FRAC (Regional Fund for Contemporary Art) in Besançon, France, Chrétien was responsible for the conservation of the 1993 piece Mirida by artist Richard Fauguet. Mirida consists of three translucent silicone rubber horse heads covered in glass marbles. The silicone heads are somewhat soft and intentionally deformed to evoke Fauguet’s dreamlike aesthetic. The heads were damaged from the mounting screws and the silicone had discolored. Conservation was necessary, but no alterations could be made to the piece without permission from the artist. During an initial conversation Chrétien had with the artist to discuss the condition of the piece and its need for conservation, Fauguet was concerned that the silicone had discolored too severely and he believed that the best approach would be for the piece to be remade, either by him or by Chrétien. The collections manager immediately rejected this proposal, however, since in reconstructing the piece its authenticity would be lost. Once Fauguet was able to come see the condition of the piece in person, he determined that the discoloration was not as drastic as he feared and agreed to treatment of the original work. Chrétien mended the horse heads with Beva and constructed new mounts and crates that offered more support to the silicone forms. Chrétien had to navigate complex ethical considerations through multiple conservations with the artist, his colleagues, and her colleagues at FRAC to arrive at the best outcome.
This collaborative experience served Chrétien well during her more recent work at a Buddhist monastery in northern India. The monastery was preparing for a new exhibition space, and many of the clay figures and masks used in religious ceremonies were in need of conservation treatment. These objects had never been repaired by outsiders, only local members of the community. Chrétien interviewed the monks to learn more about how the objects were used and their goals for treatment. People still leave offerings at the objects, which serve as homes to various deities. The deities will leave when the object becomes damaged, so they must be repaired in order to invite the deity back to reside there again.
Since the Buddhist objects were being actively used, they couldn’t be treated in the same ways ethnographic objects are treated in Western museums. As a result, Chrétien and her fellow conservators had to take an approach that is more similar to working with living contemporary artists. Chrétien drew interesting parallels between conservation of ethnographic objects in an active monastery setting and conservation of contemporary art in consultation with the artist. In both cases, the interview is a crucial tool. The conservator is an outsider and must act as mediator. And care must be taken not to privilege the norms of traditional Western conservation ethic.

43rd Annual Meeting – Object Session, 16 May 2015, “Ivory: Recent Advances in its Identification and Stringent Regulation" by Stephanie Hornbeck
Stephanie Hornbeck wrapped up the morning OSG session with her talk, “Ivory: Recent Advances in its Identification and Stringent Regulation.” She set the stage by noting how international and U.S. laws were strengthened in 2014 to combat the rise in ivory trafficking, drawing the connection to conservators since we may be involved in the identification and sampling of ivory materials. It is important for us to be aware of the methods to identify ivory and of the new regulations that apply to it.
Stephanie presented some history about ivory and its use, including a detailed description on what ivory is and how it is formed. Stephanie carefully outlined the diagnostic features for identifying different types of ivory and included a host of images to illustrate her points along the way. Some excellent resources to help with this include Stephanie’s web article for the National Museum of African Art and the Fish and Wildlife Services (FWS) website, including this page on identification. A point that Stephanie drove home is how critical it is to have comparative data when attempting to identify and unknown specimen. Photographs of morphological features and known reference material are essential tools to use. An additional aid is the use of UV light as a screening tool to classify the unknown as animal versus vegetal or synthetic. Animal ivories will fluoresce blue-white due to the presence of apatite, while other materials are likely to absorb or produce yellow or orange. Stephanie reminded the audience that the presence of Schreger lines is indicative of Proboscidean ivory, and the angle of the lines can help distinguish between mammoth and mastodon versus elephant. However, she also pointed out that the angle of the lines is variable depending on where along the tusk the lines are being examined. Beyond these visual tests, Stephanie also outlined analytical methods that require sampling. These included FTIR and DNA for identification, as well as isotope analysis, bomb-curve radiocarbon analysis, and the potential of measuring water ad/absorption as methods for possible dating.
From here, Stephanie shifted gears to talk about the ivory trade and new international, federal, and state regulations. She pointed out that the US is the second largest consumer of ivory behind China and that the ivory trade is often a cover for other illicit trade. Although ivory was already a highly regulated material since the 1976 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), these facts, along with the rapidly diminishing population levels of the elephant due to rampant poaching, have led to newer, tighter regulations. After an outline of the various laws and regulation that affect ivory, Stephanie explained that it is now illegal to buy or sell ivory of any age. Only well documented works that can prove a date of more than 100 years and ownership before 1977 can enter the US. The new requirements ask for species-specific identification and specific dating. These regulations are problematic because identifying and dating artifacts to those levels is difficult, if not impossible. The FWS has provided useful information on the new regulations here.
Because of time constraints, Stephanie was not able to fully delve into the implications for traveling exhibitions. She skipped over a case study in which documented ancient ivories owned by the Bolton Museum in Bolton, England were delayed at the Miami International Airport for four days in a tropical environment where climate controls were unknown. Following the new 2014 regulations, the local FWS agent wanted species specific identification of the ancient ivories, which was not readily proven in the existing documentation. That level of identification is also not possible to obtain without destructive analysis. Although ancient worked ivories should have been allowed as part of a traveling exhibition, and CITES permits were provided, the entry into the US was nevertheless delayed at great risk to cultural artifacts. For this reason, coupled with her long-standing research interest in ivory, Stephanie has joined a sub-committee to help develop an AIC position paper on the subject.

43rd Annual Meeting- EMG + OSG Session, May 15, "The Butterfly Effect: A Case Study on the Value of Artist Collaboration in the Conservation of Ephemeral Material" by Christa Pack, Tasha Ostrander, and Mina Thompson
Christa Pack presented a beautiful collaboration that took place at the New Mexico Museum of Art between staff conservator Mina Thompson, herself, and the artist Tasha Ostrander. The artwork Seventy-Three in a Moment was acquired recently by the museum after it had been displayed outdoors on a portico. The conservation work was also mentioned in an article published in “Ongoing” a Santa Fe New Mexican paper.
Christa started out with documentation on the materials and working method- the work is a butterfly mandala with a butterly representing each day in the life of a 73 year-old, the average life span of a person in 1996, the year the work was made. Tasha became involved in the process and eventually made additional butterflies- photocopies that were individually cut out- to add to the work. At a point in the conservation process they realized that Tasha should make the replacement butterflies and work on the integration- there weren’t enough of the detached butterflies and although many were numbered, there was no obvious logical sequence.
In this process they moved away from the YES! paste used by the artist and instead chose Aquazol. Christa spoke about the value of the artist’s voice and participation in restoration of the conceptual components. The process required mutual trust and respect. Christa ended with a nice video of the artist telling in her own words about the project… I’m paraphrasing… when Tasha saw the work in the lab, she was sad, but also thrilled to have some control over the piece since it was sold. She felt like the process was bringing the work back to life; re-entering into the past.
What surprised Tasha about conservation? The artistry, patience, pain-staking, get the job done, whatever it takes, discovery, and courage
A great collaboration that saw a new relationship and friendship emerge.
43rd Annual Meeting, Electronic Media and Objects Joint Session, Co-Organized by Voices in Contemporary Art (VoCA), May 14, “Beyond the Interview: Working with Artists in Time-based Media Conservation,” Kate Lewis
Kate Lewis, Media Conservator at the Museum of Modern Art, spoke about communicating with artists, a daily practice for time-based media conservators. Time-based media art is inherently dynamic and its conservation requires ongoing collaboration throughout the life-cycle of a piece. Gathering information from an artist is a cumulative process, with opportunities for both formal and informal conversations at multiple stages, from acquisition to condition checking to installation.
The first opportunity for conservators to communicate with the artist is at the point of acquisition. This is a chance to gather information about the media production history and specifications for the technology needed to show the piece. Initial contact generally happens via email; for efficiency and consistency, Lewis has a standard set of questions that she sends to artists.
The next point at which communication with artists happens is during the condition checking phase. This is when all of the media in the piece are examined to ensure that the necessary files and equipment are present and working properly. Gathering information at this point can be a challenge; artists are often busy and may feel rushed, especially if they don’t fully understand the more technical concerns.
It is often at the installation stage that museum staff conducts a formal artist interview. Installation is the first time the staff has a chance to experience the art, and it’s at this point when final tweaking of volume settings and other technical details happens. There are so many people involved and there are many conversations happening between museum staff and the artist, that capturing important snippets of information can be tricky. Lewis likes to audio record whenever possible, in addition to taking notes, and then follows up with more formal questions later on. Post-installation is often the ideal moment for more in-depth conversations with the artist.
Lewis spoke to the importance of revisiting questions with the artist multiple times. A cumulative approach is inevitable, given time-constraints and the nature of these interactions, but it also affords an important opportunity to develop trust and empathy for the artist and the piece. It can take a while to get the artists away from their canned “spiel.” It can also take time for conservators and other museum staff to understand and appreciate, even if they don’t agree with, an artist’s point of view.
Some artists are elusive but exert a lot of influence over their work. Lewis talked about a few artists she’s worked with whose pieces have very specific technological requirements that will face obsolescence in the not-too-distant future, and an unwillingness (at least at this point) on the part of the artists to discuss hardware, software, or format alternatives. Lewis and others in the room speculated that artists don’t always want to talk about how components of their work might change; they might be resistant so that things won’t be changed too soon, forcing conservators to work a little harder to keep as faithful to the original for as long as possible.
Lewis made the interesting point that time-based media art is so new and dynamic that we’re still determining what counts as “patina” for these works; ongoing conversations with artists help us figure out what elements may be altered or replaced and what must be saved in order to retain the authenticity and integrity of the piece.
43rd Annual Meeting – Objects Session, 16 May, "Beloved Treasures: Assessing the Effects of Long-Term Display on Models Containing Wax" presented by Marissa Stevenson
Marissa Stevenson presented on the effects of long-term display on the “Libbey Dolls” in the Toledo Museum of Art. The dolls were created in 1915 and are named for the collector who purchased them. They depict characters popular in the later nineteenth and early twentieth century using multiple types of media that include wax, plaster, feathers, fur, human hair, lace, plaster, cotton, plant material, wire armatures, and more. After full-time display for over fifty years, along with two interventions that date to pre-collection in 1917 and to 1951, the dolls were showing damage. During that time, the dolls were exposed to incandescent lighting with the associated light and heat conditions, fluctuating environment, and lack of support on display. The result? Disfigurement, cracking, light damage, and other structural damages, topped off with a healthy dose of dust and grime.
The conservation study focused on the wax and included identification and treatment. Through IR analysis, the wax was identified as bee’s wax, which was observed to become brittle and darken. It was applied in four layers, with two layers of plaster supporting it. Cleaning tests of 1% ammonium citrate, saliva, methylcellulose with deionized water rinses, and gels, showed that wheat starch paste and saliva were the most effective. Adhesive tests with Jade 403, Aquazol 500, Rhoplex AC33&N58, Avalure UR450, Avalure AC120 showed that Avalure AC120 and Aquazol 500 preformed best. The Avlaure also supported good pigment dispersion, so this was used in areas that needed pigmented fill material. Since Avalure has not been tested as an adhesive, Stevenson chose to use it to adhere a broken leg in her case study. The leg’s hidden location will allow them to observe how the resin holds up over time without compromising aesthetics should it prove to be problematic in any way. Since the head is in a visually prominent location, and Aquazol has been tested as adhesive with good results, it was used there.
With the wax issues under control, the next step will be to investigate what the clothing’s needs and to address them. Finally, storage mounts need to be made. Solutions will need to consider how to fully support the dolls, and will in some cases necessitate horizontal storage, and in others vertical storage. Fosshape is a likely candidate for helping to create these supports, forming it on Ethafoam model. An audience member brought up the idea of using Varaform fabric for the mounting system since he said it is less bulky than Fosshape, comes in 3 weights, and though it is heated to use, it is not thermally conductive. This was a new material for Stevenson, who said she would investigate. This also led to a brief discussion regarding to long-term storage. Since Fosshape has pass Oddy testing, it seems like a good idea, but we do not know about its aging properties, so question was raised about it being appropriate for long-term storage.
43rd Annual Meeting – Objects Specialty Group Tips Session, May 16, “Lacquer Fills” by Ellen Promise, with Jessica Chloros and Holly Salmon
During the OSG tips luncheon, Ellen Promise, currently of Historic New England and formerly of the Isabella Stewart Gardner Museum, presented new techniques for filling and inpainting lacquer. The techniques, developed in collaboration with Jessica Choloros and Holly Salmon, are readily applicable to many types of objects, not just lacquer.
Lacquer objects, especially those damaged by light, have very sensitive surfaces; therefore creating fills in situ can be dangerous. In the technique presented, Golden Acrylic Regular Gel Medium in matte was mixed with acrylic paint to a frosting-like consistency. The tinted mixture was then cast out onto silicone release mylar. After drying, the paint film remains flexible, has the bulk required for a fill, and resembles the sheen of aged lacquer. The paint film is trimmed to shape with a scalpel and then adhered in place with fish glue or B-72. While the fill isn’t invisible at the edges, it is harmonious with aged, cracked lacquer and remains reversible.
Promise also described her experiments with inpainting lacquer, specifically the fine gold lines often found on these objects. While acrylic paint is easy to use, the texture and shine is often not a good match. Promise tested several other options – metallic pens and markers, metallic paints, and mica powders dusted over sizes. She evaluated the materials for color, texture, gloss, and adhesion to an acrylic substrate. For the object in her case study, a Chinese export table in the collection of Historic New England, she had the best results with a Decocolor opaque paint marker. The marker was a good color match and had a high pigment load without bulk. The marker, which produced a fine line, could be used directly on the fill, or the ink could be dispensed into a palette, mixed with solvent, and brush applied.
AIC 43rd Annual Meeting- Architecture Specialty Group Session, May 16th: “One Piece at a Time- The Repair of Felt-Bases Sheet Flooring at Johnny Cash’s Boyhood home in Dyess, Arkansas” (Christina Varvi)
Christina first discussed the location- a New Deal planned farming community of 500 homes. It is now the only surviving home from the community and the town now has only 388 residents today. The home was acquired by the Arkansas Heritage Sites if Arkansas State University, located an hour and a half away. The home was furnished with 2 rooms of original flooring and objects owned by the family augmented by furniture dating to the time and 2 rooms of floor covering belonging to nearby Dyess Colony houses. The house was to be opened as a historic site for visitors in August 2014
RLA (Rosa Lowinger & Associates) was brought in at the end of the project to conserve the original floor coverings. Consideration had to be taken into account that the living room flooring would be walked on. There was little time and budget due to this being an add-on to the project at the last minute. The original estimate was double what the project could afford. Discussions led to a scale back in the project and priorities were set to what was most important to happen right away. Treatment was mostly confined to the 2 original-to-the-house floorings- those in the living room and Johnny Cash’s boyhood bedroom. Treatment was confined to cleaning (vacuuming and surface wet cleaning), stabilization of tears (on back with Japanese tissue and B72), fills and in-painting on living room flooring, and varnish (applied by brush) to protect the surface of the flooring. The non-original-to-the-house flooring was not varnished. Recommendations for now are furniture pads to protect the floor underneath, recommendations for visitors to remove shoes and use booties in the living room and roller shades to reduce light during off hours. Next steps are to raise additional funds to finish work on the floor, work on additional buildings on site (outlying farm buildings) and to raise funds for a visitor center.
There were many complexities to this project: the area was very rural, there was no running water in the house, the house was climate controlled but not airtight, no shops to be able to get supplies and the client was an hour and a half away. Everything had to be brought in. Additionally since the floor covering project was a last minute addition, furniture was already in place and could not be moved out of the house. With careful planning, much more was accomplished in the time given than was though possible and the treatment was a success.
AIC 43rd Annual Meeting- Practical Philosophy General Session May 15th: “Suspended Rules for Suspended Worlds: Conserving Historic Stage Scenery” (Mary Jo (MJ) Davis)
I was interested in this talk because it seemed an interesting intersection between textiles and objects together with the complications of working on objects that are still in use.
MJ discussed the set of challenges of working with historic stage scenery: climate, use, lack of funds, space to do treatments, ect. The “Curtains Without Borders” team (started 15 years ago in the state of Vermont) of conservators came up with a standard method of treatment that could be applied, with some differences as need, to the stage curtains. The typical treatment consists of: on-site technical examination, cleaning (vacuuming and dry sponging), mending tears with patches of muslin w/B72, inserts to areas of loss, consolidation of edges (all sides reinforced with muslin w/B72), structural support at top edge if necessary and reattachment of bottom roller, paint consolidation (sprayed B72), in-painting of losses and reinstallation with volunteers or professional riggers as needed. All work is done onsite by conservators and a team of local volunteers (with at least 2 at all times). Many conserved curtains have been revisited over the years and additional issues have been attended to. Issues have mostly come from handling of curtains once they were re-installed.
The project has been a success all over New England- with more requests coming in from all over the country for help. There are plans to continue the project and expand territory.
2015 Annual Meeting EMG/OSG/VoCA Joint Session: Collaboration with Artists in the Preservation of Artistic Heritage
The Electronic Media Group (EMG) and Objects Specialty Group (OSG) of the American Institute for Conservation (AIC) are joining with Voices in Contemporary Art (VoCA) to present a special joint session on the topic of collaboration with artists at the upcoming AIC Annual Meeting in Miami, FL, May 13-16, 2015.
Recognizing that artists have a stake in the legacy of their work has shifted conservation practice in recent decades. Moreover, it is possible to maintain a critical art historical discourse while also integrating the voices and opinions of the artists within preservation strategies for their artworks. The mission of organizations like VoCA has been guided by the possibilities of this shift. Increasingly, these practices are flourishing at major museums across the country.
Many conservators are actively seizing opportunities to interview and otherwise interact with artists. This session provides a venue for novice and experienced practitioners alike, from conservation and allied preservation-related fields, to share their outlook on and practice of collaboration with artists and their associates.
The sessions will be take place on Thursday, May 14, from 2pm-5:30pm, and Friday, May 15, from 8:30am-12:30pm. A ½ hour discussion will be held at the end of each day’s talks, led by Jill Sterrett on Thursday and Glenn Wharton on Friday.
The full schedule for the joint sessions is available here.
