http://www.connectingtocollections.org/preservation-metrics-today-heritage-health-information-and-preservation-statistics-2/
Now more than ever, data drives decisions: Which projects should be funded? Where is staff needed? What activities should take priority over others? How can you find the data to help when you are looking for funding or trying to persuade your community or legislators to provide funds for collections care in you museum, historical society or library? Collections care is an ongoing process and the need for caring for collections doesn’t go away when times are lean. Having your specific needs spelled out can help you make a persuasive argument for future funding.
The Heritage Health Information and the Preservation Statistics programs are both dedicated to collecting and analyzing the information on care for our collections in the broadest sense and they are the go-to programs for the data you need.
This webinar will give you the chance to learn more about these programs and to learn about how you might use the information they provide for your own situations. It will also help you to address StEPs MVG Standards 3 and 4.

43rd Annual Meeting – “Investigating Softening and Dripping Paints in Oil Paintings Made Between 1952 and 2007” by Ida Antonia Tank Bronken and Jaap J. Boon, May 14

Issues encountered during analysis and treatment of contemporary artworks by conservation scientists, conservators, and other professionals have been brought into the limelight during recent years. Both in the United States and throughout the world, contemporary art collections have introduced new concerns regarding the use of modern materials, artists’ intent, and so on. Even the modern use of materials such as oil paints have demonstrated conservation issues. During this presentation, Bronken described her team’s research into oil paintings (created after 1950) which have exhibited softening and dripping media. The team’s research was conducted on works produced by Jean-Paul Riopelle (Canadian, 1923-2002), Pierre Soulages (French, b. 1919), Georges Matthieu (French, 1921-2012), Paul-Émile Borduas (Canadian, 1905-1960), Frank Van Hemert (Dutch, b. 1956), Paul Walls (Irish, b. 1965), Jonathan Meese (German, b. 1970), and Tal R (Danish, b. 1967).
Softened paint shows decreased surface gloss in normal light and drip material fluoresces in ultraviolet light (sometimes misinterpreted as fluorescing varnish). Softening/dripping impasto and thickly applied paints are easier to identify, but analysis has demonstrated the presence of softening in thinner paint layers as well. Possible causes of this phenomenon are the use of semi-drying oils in recent decades and the development of fatty acids in paint. In their abstract, the authors mention: “There is ample evidence from a number of paints studied by mass spectrometry that the exudates are rich in polar fractions with triglycerides with moieties of mid-chain oxygen-functionalised stearic acids and azelaic acids . . . observations led to the hypothesis that exudation is caused by a loss or absence of anchor sites for the acidic fractions that develop over time.”1
Details from Peinture (1954) by SoulagesTest area from the Seven Series (1990-1995) by Van Hemert
Lead II acetate and europium II acetate were tested by brush and gel application. These compounds treated the softening and dripping oil paint at the molecular level by penetrating into the sample to create carboxylates and forming a hard crust on the paint surface. Brush application was determined to be the most effective method. At this time, the only disadvantage appears to be the lack of reversibility.

43rd Annual Meeting – Book and Paper Session, May 16, “Unlocking the Secrets of Letterlocking to Reseal the Letters of John Donne and Other Early Modern Letter Writers", Jana Dambrogio

Jana Dambrogio, Thomas F. Peterson Conservator, MIT Libraries, presented the first of three sections in this talk – an introduction to the work she and others have been doing to discover letterlocking.
As letterlocking models were handed out to the audience, Jana began by defining letterlocking as “the folding and securing of any object so that it becomes its own sending device”. This is a 10,000 year tradition, Jana said, dating all the way from Mesopotamian clay tablets to Bitcoin.
Examples of letterlocking Jana showed included the letters of Tomaso di Livrieri at the Vatican secret archive and the letters of Queen Elizabeth I. Queen Elizabeth used more than ten techniques in her letters, often with two techniques per letter.
Jana described how letters of this type have traditionally been viewed simply as two-dimensional objects. But as a result of this research conservators and scholars are beginning to look at them as 2D/3D hybrids, and they must be treated accordingly.
Jana and her colleagues have been constructing models of the locking techniques based on evidence in the original letters. Jana believes that making models of letterlocking techniques is helpful because they are both a learning tool and a teaching tool for discovering and sharing the patterns.
If the goal in conserving these letters is to preserve their past function conservators are faced with the decision of what to repair and what not to repair, and the question of how to preserve the evidence.
During her talk Jana highlighted recent collaboration such as with Nadine Akkerman of Leiden University in The Hague, with Daniel Starza Smith of The University of Oxford, and with Heather Wolfe of the Folger Shakespeare Library.  See links to various demo videos, blogs and publications that have resulted from these collaborations at the end of this post.
 
Daniel Starza Smith spoke about applying letterlocking to literary history.
Normally scholars look only at the text they can see in letters. But now they are learning to look for folds, seals, and intentional damage – the damage that occurs as a result of opening a letter. These days Daniel asks himself ‘what other messages are there than just who the letter is from and to?’
He took us through some basic background on the development of the writing and sending of letters, from a manual for letter-writing, The English Secretary published in 1586 by scholar Angel Day, to the relatively modern invention of the commercially-produced paper envelope in the mid-19th century.
Daniel noted that the word “secretary” itself comes from the idea of secret keeping. A secretary is one entrusted with secrets, and literary scholars such as Daniel are occupied with revealing secrets and unpacking texts – now in a physical sense.
Delving into the letters of John Donne, Daniel revealed that Donne would use as many as four techniques in locking his letters. Why would you need four ways of locking? For various different purposes, including security and aesthetics. In fact there was even a class difference in the way letters were folded; your folding technique said something about you as a person. Some methods were simple and some were complicated – even “fantastically difficult” – and this reflected on your own sophistication and status.
Daniel concluded his talk with the following three main take-aways:

  1. Tiny bits of evidence are key in deciphering the folding/locking patterns, and these details are revealing about the history of communication.
  2. This research has the potential to reach further than just scholars
  3. The collection of Donne letters – from which much of this research has stemmed – numbers only thirty-eight. More data is needed, and this starts with conservators.

 
At the beginning of her portion of the talk Heather Wolfe emphasized three points that have come to light during this project.

  1. The importance of a three-way dialogue between curators, conservators, and scholars.
  2. This dialogue leads to discoveries, and informs decision making in conservation when considering whether or not to treat
  3. The need to standardize letterlocking vocabulary, referring to physical details. This is especially important in treatment documentation, and also for catalog searching.

In what Heather described as the “pre-envelope era” a letter was a single leaf that was transformed into a packet. Tearing was required in order to open the letter, and this is the damage we can see today that aids in reconstructing the locking patterns.
Communication with Jana was informative for interpretation of the collection at the Folger – Heather noted that the type of evidence in question tends to me more visible to conservators. For example, Heather no longer refers to the area bearing the address as the “address leaf” of the letter, but rather the address panel of the original packet. Heather went so far as to say that physical evidence such as the folds and intentional damage contains information critical to the interpretation of the letter itself.
She reiterated Jana’s remark that it is very difficult to imagine the folding and locking patterns without practice, and this is the reason they decided to make models.
In letters from the 16th-17th centuries there is evidence of hundreds of riffs on just a handful of basic techniques, such as the pleated letter genre, and the papered seal genre in which a strip is harvested from the letter itself to use as the locking mechanism. The many riffs tend to be associated with specific people.
Finally Heather took us on a whirlwind tour of these various letterlocking genres, but particularly highlighted the technique of binding a pleated letter with silk floss, first used by Queen Elizabeth I. Heather pointed out that while many letters would have been written in the hand of a secretary taking dictation, the nature of this technique suggests more intimacy. Letters of this type were usually written in the hand of the person composing the letter on high quality thin Italian paper.
 
Question and answer
Q: Have you seen any evidence of postal censors opening letters?
Heather said that she had not seen this specifically. But in the same vein she noted that a distinctive triangular-shaped 20th century Russian letter from the WWII front that was invented due to adhesive being forbidden.
Daniel pointed out that in the early modern period, people would sometimes employ a seal forger, in order to open and re-seal letters; he has seen some examples of this.
Q: Are you presenting these findings to archivists (specifically for the purpose of standardizing vocabulary? Where will you be publishing the vocabulary?
Heather said that the vocabulary is still in development, but that there are currently a lot of resources online, such as the MIT TechTV videos, the youtube letterlocking channel, and blogs. Heather has written in a recent British Library publication on pleated letters, and Jana has a forthcoming article.

43rd Annual Meeting – Architecture Specialty Group – May 15, Concrete Actions to Extreme Risks: Conservation of Humberstone and Santa Laura Saltpeter Works World Heritage site in danger, IQUIQUE, Chile, Alicia Fernandez Boan

Humberstone Salitrera Iquique Chile taken by Carlos Valera on December 30, 2012

During the Architecture Specialty Group Session, Alicia Fernandez Boan focused on the conservation efforts and needs for two World Monument sites that represent the salt peter mining era in Chile.
The salt peter works are remains of human activity in the Atacama desert. Operation began as part of Peruvian territory in mid-19th century. They were declared world heritage sites in 2005. Humberstone and Santa Laura represent over 200 salt peter works that once existed. The Atacama desert has a temperature extremes from 0 deg c at night to 40 deg c midday, which takes it’s toll on the built environment. The cultural landscape is made up of the structures and surrounding site that is formed due to the accumulation of byproducts of the mining efforts.
At Humberstone, the structures and buildings of the community remain — church, school houses. Alternately, Santa Laura is representative of the industrial sectors found in saltpeter works. The materials are exposed to extreme weather. The structures are also exposed to salts and chemicals that were part of the production. There are dozens of rust colored structures. They include generalized corrosion and galvanized losses.
In order to maintain these sites, several factors must be considered. The conservation of urban sites requires establishment of commercial activity so that the site can be self-sufficient and sustainable. Therefore rehabilitation, recycling, controlled use, and the reoccupation of the territory is greatly needed. Use of these sites as museums documenting the industrial age of salt works is currently happening but more is needed. Rehabilitation, recycling, controlled use, the reoccupation of the territory works will be necessary for the long-term preservation of the sites.
From a conservation standpoint, the sites have conservations needs but they offer the possibility of a conservation field laboratory. This is a place where cleaning tests and environmental aging tests could offer substantial information to the preservation community. The sites offer the ability to study corrosion on a monumental scale under extreme weather conditions.

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 – Opening Session, May 14, Concrete Conclusions: Surface treatment Trails for Conserving the Miami Marine Stadium by John A. Fidler, Rosa Lowinger, et. al.

“This presentation by John A. Fidler and Rosa Lowinger focused on testing cleaning methods for removal of graffiti from concrete surfaces at the Miami Marine Stadium. The work is being undertaken by the Friends of the Miami  Marine Stadium with funding by the Getty Foundation.
The stadium is an excellent modernist structure designed by the Cuban-American Architect, Hilario Candela. The building includes a 326 foot-long cantilevered thin shell concrete roofline that is among the longest in the world. The Stadium was created for speedboat racing but was also used as a concert venue, and featured artists such as Jimmy Buffett, Sammy Davis Jr, and more. The stadium is owned by the city. It was closed in 1992 after Hurricane Andrew and has fallen into a state of disrepair. It has become the central site for graffiti artists in the Miami area and the surfaces of the stadium are covered with multiple layers of graffiti.
Because of it’s unique and original mid-century design, the Miami Marine Stadium is the recipient of the Getty Foundation Keeping It Modern Initiative funding. This is one of nine structures to have received this type of grant. This funding has allowed for testing graffiti removal methods and evaluating concrete repair materials for the project. This 12 month testing phase is due to be completed this summer, but the project will be on-going.
The Friends of the Miami Marine Stadium are working diligently to save this structure from a city demolition order that was issued in 1993. There is concern about the welfare of the deteriorating concrete and the structure’s hurricane resistance. The project requires both civil engineering expertise and conservation skills. In addition to materials conservation issues, the cultural and social use of the site as a graffiti sanctuary must also be addressed. Repair of the concrete in many places will require the removal of many of the graffiti works. While much of the graffiti designs are undertaken using acrylic or polyurethane enamel car touch up paint, there are more than 200 types of paint materials used to create the graffiti art.
The project will require graffiti management for current and possible future tagging. Initial meetings were held with the graffiti artists to convey that there is intent to honor the role of their work, to record the work, and to provide creative ways to archive or show the work. In the future there may be walls placed for graffiti artists to continue their efforts.
Current conservation research efforts are focusing on three lines of study – graffiti removal, anti-graffiti protection, concrete repair. Graffiti removal is focusing on both mechanical and chemical methods of removal. Mechanical techniques include dry-ice abrasion and/or laser cleaning. This may also be followed by chemical methods such as Dumond’s Smart Strip Pro, or custom chemical blends using 5% formic acid and benzyl alcohol. To protect surfaces from new graffiti additions, anti-graffiti barriers are being tested. These treatments may include Dumond Chemical Watch Dog, as well as Keim, and Prosoco products.
Concrete patch repair is focusing on stable long-term materials. Worldwide over 90% of concrete repairs fail within 10 years. Thus, it is important to test potential patch materials in actual environments prior to treatment. Also, the surface textures and finishes will be a challenge to conservators. Materials selected for testing include:

  • SIKA Mono-top
  • BASF Emaco Repair
  • Edison Coatings System 45
  • Cathedral Stone Jahn M90
  • Custom Mixes

Results of this research will both guide the treatment of the Miami Marine Stadium and serve as a guide for the treatment of other mid-century modern concrete buildings and structures.

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 Group Session, May 16, "The Fragile Surface: Preserving the CD-DA by John Passmore

John Passmore works as the archives manager at WNYC. They have audio recordings that go back to the earliest days of radio– about 100 years now. As a listener of WNYC it was very interesting to hear about how they are caring for their archives. WNYC does a lot more than just radio- like many media producers, they are a multi-platform production company with born-digital content. In the audio preservation lab they are able to digitize and preserve almost all media types, which is an anomaly in the public media world.
That being said- between 2000-2008 they created ~30,000 digital audio cds which were created and finalized by the engineers at the time of the broadcast. About 5 years ago they started to notice some problems with them being unplayable and hard to rip. It was possible to extract the .wav file, but it would sound terrible. Being worried about the health of these formats they created a workflow to migrate them in an efficient and responsible manner. Some have obvious manufacturing defects, but the scary thing is that usually you can’t see something visibly wrong. The most commonly believed reason that cds fail is due to degradation or failure of the dye layer. This is extremely small- at 0.5 micrometers this is about 1/100th of the width of a human hair!
To migrate their collection, they bought a machine that is used to put cds onto an ipod or other digital player- it is not preservation oriented, but can concatenate .wav files dump them onto the DAM and extract the metadata. If the cd fails then they use a separate testing system. Plexstore can be used to review the data. It is also possible to run the cd in real time in a cd player and extract the info that way, but this is obviously much more time consuming. There are problems with this system and John is not totally happy with it, but it is working for now.
Now for the alarming information- they ran a test of about 20% of 2,400 discs to determine how many errors and what kind there were- correctable or uncorrectable. None of the cds passed! So the whole collection is at great risk.
John’s list of takeaways:

  1. CDs don’t last very long, maybe even less than we though- their CDs are only 10 years old, not the 20-30 usually stated in accelerated aging tests
  2. It is hard to know why the CDs go bad, and finally
  3. They are looking at open source tools like QCTools. John ended with a great video using MakeAGIF.com showing the process of his machine in process.

43rd Annual Meeting- Workshop, May 13, "Using Wikis to Collaborate, Share, and Advance Conservation" with Rachael Perkins Arenstein, Michele Derrick, and Suzy Morgan

This year, the annual meeting wiki-a-thon turned into a daylong workshop in the hopes that we would have more time to add content to the site. Thanks again to NCPTT for helping to fund the day! Although we never seem to have enough time, the day was immensely helpful in getting beginners comfortable with adding content to the site and moving the more experienced users forward to another level with useful tips and problem solving for getting the wiki to do what we want.
After introductions, Rachael started with a useful overview of the wiki site and general goals. She also gave a brief talk put together by Leon Zaks (from the pestlist) about how to choose your online platform. Basically the wiki is a many to many platform- there are many contributors with loosely vetted content meant to reach a large audience.
Michelle presented on CAMEO, which is hosted by the MFA Boston. It has recently been moved to a wiki format so that it can be more easily updated- hopefully by more than just Michelle. Anyone interested is welcome to contact Michelle. CAMEO is a great resource and the wiki is not meant to duplicate it, but there is definitely room for increasing the connection between the two and improving the integration of the sites.
Unfortunately Nancie Ravenel was not able to make it, but we had Nora Lockshin available to step in and provide lots of great information about wikipedia in general, what are some of the ground rules and expected conduct on the site. If you didn’t know, there is a wikipedia teahouse made for newcomers- this is a great place to post questions and get answers about coding. Just beware- the AIC wiki does not have all of the extensions and add-ons, so something you can do on Wikipedia isn’t necessarily possible on the AIC Wiki. That being said, if there is anything you want to do and can’t let Rachael know and she can look into getting that functionality on the site.
Two other wiki sites, you should know about Preservapedia (also sponsored by NCPTT) and the SPNHC wiki which is just getting off the ground.
Other tidbits you should know that came out of the day:

  • Creative Commons is a way of licensing images to limit their use by others, or make them available to all
  • when searching through google images or flickr, you can filter those that have the CC license
  • there is a great slider tool to help you determine if something is still under copyright or in the public domain
  • The AIC has a policy and expects that if you post something, you have gotten the proper permissions and you have given AIC permission to publish and re-publish content in perpetuity, so that they can migrate to a new platform when needed in the future.
  • When adding images- be aware of their size. Please resize before uploading.
  • Zotero is a great open source citation tool- the exported citation format for the wiki is not exactly right, but could save you a ton of time when adding citations.
  • Check out the Categories page from Special pages- these can be used to “tag” pages in a way to help link them together.
  • For the non-beginner training session Suzy put all of her notes on the wiki under the news section, so you can find all of her great tips there.

Happy wiki-editing!
