43rd Annual Meeting – ECPN/CIPP Happy Hour, May 13

Before the opening sessions began, the Emerging Conservation Professionals Network and Conservators In Private Practice co-hosted an evening happy hour at the Hyatt Regency Miami (sponsored by Tru Vue, Inc.). Everyone at the conference was welcome as this event was not ticketed. Appetizers present included breads, cheeses, hummus, fruits and vegetables, and even mini burgers. Alcoholic and non-alcoholic drinks were available for purchase.
Attendees ate, drank, and mingled indoors on the Promenade or outside on the Riverwalk Terrace (image below). The event was well attended with probably between one or two hundred people networking and having fun. Some people decided to stay inside the air conditioned building while others went outside to enjoy the 80˚ weather and view of the Miami River. There were tables and chairs available for small groups to gather, and alternatively, many small groups also chose to sit on the steps and relax.
I certainly recommend those of you who did not attend to do so at a future conference, especially if you are an emerging professional. This happy hour was an excellent opportunity to meet the other attendees. If you are someone who is nervous about attending, please remember that this is supposed to be laid-back and other people want to meet you too. If you know some people at the conference, feel free to begin the evening with them. But after you are more comfortable, you should also make an effort to branch-out and talk to people that you do not know. And do not forget to distribute business cards to your new contacts.
If you want to learn more about other networking opportunities open to attendees, you should read reviews for the Opening Reception, Specialty Group Receptions, and Emerging Conservation Professionals Luncheon.

British Museum, 20-21st April 2015. Symposium on the care and conservation of human remains with a focus on natural mummies.

How comfortable do you feel surrounded by skeletal remains and natural mummies? The symposium hosted by the British Museum left no areas unturned, from the excavation, conservation and curation of natural mummies, and allowed participants of the day access to natural mummies from their extensive collection.
Daniel Antoine, curator of physical anthropology at the British museum, kicked the day off by considering the legal aspects and ethics in the curation of human remains. A huge 91% of the British population appears to be on side with the display and retention of human remains by museums for research purposes, but there are obligations. The display of human remains less than 100 years old does not sit well on some peoples’ shoulders and named remains attract a similar apprehension. This seems at odds with the display of Egyptian mummies that often have their names inscribed on their cartonnages, but maybe the longevity of these mummies makes their display more palatable.
Derek Welsby, assistant keeper in archaeology of Sudan and Egyptian Nubia, and Daniel Antoine followed with a description of the problems involved in the excavation of skeletal remains and natural mummies from their resting places, in this instance, the fourth cataract of the Nile Valley, Sudan. Skeletal remains dating back to the Neolithic period were uncovered from various burial sites and natural mummified bodies from the medieval period were excavated from this previously understudied region of The Sudan. Over a 1000 skeletal remains and naturally mummified bodies were donated to the British Museum by SARS, the Sudan Archaeological Research Society via the National Corporation for Antiquities and Museums of Sudan. For the past two years the British Museum have been undertaking research into population genetics and the pathology of these Nilotic human remains. A human remains database has been created by the museum that will open up the research potential of these people, negating the need for physical interaction and reducing the risk of damage to the bodies.
Barbara Wills, conservator of organic artifacts at the British museum had the job of surveying the mummies. She examined, photographed, assessed the needs of each individual and established a strategy for stabilization. Barbara was in the wonderful position of receiving a Clothworkers Conservation Fellowship that allowed her to put all of her time and effort into the development of a passive method of stabilization and display. Barbara has a wonderfully calm demeanor that exudes respect for humanity. I don’t know whether she had this disposition before she started work on the mummies or whether the mummies taught her this respect on her travels with them. A workshop on the second day of the symposium allowed for the exploration of these stabilization and display methods that Barbara developed during her fellowship and shall be discussed later.
The life of the Nilotic people is unraveled not only from research into the human remains but also by analyzing the textiles and leather excavated along side the bodies. Caroline Cartwright, from the department of conservation and scientific research at the British Museum, gave an excellent talk about the problems and pitfalls of trying to identify materials that may have been in close proximity to soft tissues and Anna Harrison, a senior conservator of organic materials at the British Museum, followed with the issues surrounding the conservation of archaeological textiles. Of particular fascination was the discovery of human hair mats that were treated like dry archaeological wool and the revelation that an imprint of a textile may be present on a skin sample even if the textile no longer remains.
 
A lunch break allowed time for a visit to the temporary exhibition: Ancient Lives, New Discoveries, where a number of the curatorial issues discussed in the morning session could be seen in practice. The use of explanatory and contextual information was well presented and tasteful lighting within display cases offered respect to the mummies.
 
Nancy Odegaard from the University of Arizona and Arizona State Museum resumed proceedings by discussing the post-excavation deterioration of the Chinchorro mummies of Arica, Northern Chile. The storage facility for the mummies is far too hot and humid and the mummies are acting as the environmental buffer. Deterioration was manifesting itself in the form of a ‘black ooze’ emanating from the bodies. A quick, easy and inexpensive solution to this problem was the introduction of some locally sourced hygroscopic wall coverings that took over the work of attempting to stabilize the environment.
A Sudanese mummy offered Joanna Russell, from the department of conservation and scientific research at the British Museum, the opportunity to use HPLC to investigate the dyes present in colourful textiles adorning the body. All dyes identified, Pseudopurpurin, Purpurin, Alazarin and Indigotin were used in Egyptian dying.
Marie Vandenbeusch, a project curator in the department of Ancient Egypt and Sudan at the British Museum, used infrared reflectography on a tattoo found on the upper leg of a naturally preserved female mummy from medieval Sudan. The tattoo represents one of the earliest known surviving examples of a tattoo from this period and region and represents a Christian monogram of the Archangel Michael. (images found at: http://blog.britishmuseum.org/2014/06/26/tattoos-in-ancient-egypt-and-sudan/) Of particular interest was the fact that it was mainly women that were tattooed and this particular tattoo was hoped to provide protection under Michael, the patron saint of Nubia.
Heather Bonney, a collections manager for human remains and repatriation at the British Museum, discussed the general curation and digitization of the human remains collection at the British Museum. Human remains can be acquired via three different routes. They may have been purchased anatomical specimens, ethnographic collected remains or they may be from an archaeological context and each requires different legal documentation for their storage and display. Osteoware software and the Oracle Word database were then discussed for the digitization of the collection. (The Oracle Word database is really tailored towards a British archaeological context).
Finally but certainly not least Emily Taylor and Simon Prentice, museums assistants at the British Museum, gave a superb talk about the safe packing and transportation of human remains. It is essential that all remains are carefully photographed before travelling so they can be referred to after unpacking and the person unpacking the remains must be able to deconstruct and replicate the packing easily so it must be simple but effective. Cellite honeycomb boards were used instead of the old-fashioned mummy boards but beware, do not use the Aluminium version of the boards if the mummy is to be sent for a CT scan as the Aluminium interferes with the scan.
 
Barbara Wills lead the second day of the symposium. She gave us an insight into the development of an inexpensive, simple, reversible, reliable and relatively quick way of displaying human remains for display or research using Plastazote LD33 and LD45 (polyethylene foam), PTFE tape and sheets (polytetrafluoroethylene, plumbers tape) and Polyester wadding.
Plastazote LD45 covered in Tyvek (a spun bonded olefin material that is inert and gas permeable) can be placed on a cellite board onto which the mummy can be displayed. Plastazote LD33 can be cut into shape and pinned to the board, offering support or preventing movement.

There should be at least a 10cm boarder to the outside of the human remains to prevent damage to any delicate parts when being transported. Barbara demonstrated a quick and easy way of cutting the plastazote into shape using only a big sharp knife. (Figure 2)

The wonderful thing about PTFE is that it adheres to itself through static attraction only. There is no adhesive involved! PTFE sheet can be wrapped around Polyester wadding that has been fluffed, to create really soft ‘pillows’. Really soft ‘pillows’! ‘Pillows’ of the size and shape you require. (Figures 3 and 4)

Fig 4. Barbara Wills demonstrating the construction of a skull mount using fluffed Polyester wadding wrapped in PTFE sheet. Barbara made a sausage shape that she then curved round and pinned in place. Plastazote LD33 cut into wedge shapes can be pinned at each pole position to offer additional support.
A sheet of PTFE could be pinned to a Plastazote LD33 surround creating a hammock like structure. This could support very fragile parts of a body that would not survive using a conventional support.
PTFE tape can be wrapped directly around a fragile part of a body that needs to be held together and, as there is no adhesive involved it is completely reversible. When the static property of PTFE could potentially be damaging to a fragmented part of a body or where hair is present then the static can be eliminated quickly by shooting a beam of electrons at the material from an antistatic gun. Conventional tying can then be used to hold the PTFE in place.
Barbara Wills was apologetic to those attending the workshop as she considered her ideas simple. However, the simple ideas are sometimes the ones that are overlooked and missed. Barbara has developed a system that can stabilize and display any human remains without the need for chemicals and consolidants. The mummies we observed had been displayed in a manner that negated the need to move them for research purposes. However, if a research project did come along that required the movement of any of the bodies then this could be easily achieved without too much intervention, minimizing any damage that might occur to these priceless human remains.

Blog at AIC's 2015 Annual Meeting and win!

Each year we receive feedback from colleagues who couldn’t make it to the annual meeting that write-ups of the talks posted here on www.conservators-converse.org were interesting and informative.  For the past few years we had so many fabulous concurrent session that even those present at the meeting couldn’t attend all the talks they were interested in and found that they could get a taste of what they missed using the blog.  Our blog sees a huge increase in traffic due to annual meeting posts with almost 600 unique visits per day.  We know that many colleagues are looking forward to hearing more about the conference and hope that some of you will volunteer and share your thoughts from the meeting.miami

How To Sign-up:

Signing up is easy.  Just click on the link below to access the signup spreadsheet:
https://docs.google.com/spreadsheets/d/1pNEluroUP6aP_Degsdvy0Ns7PMpximU2XDYUkGHia-A/edit?usp=sharing
There is a separate tab down at the bottom for each SG or session.  Next, input your name and email next to the talk you are interested in covering.  Easy!  The limit for signup is two talks so that nobody feels overwhelmed.

What’s In It For Me?

Many people take notes at the talks and writing them up is a great way to organize your notes and thoughts while doing something great for your colleagues and the field.  Speakers are often grateful for the feedback.  And, yes there is something in it for you…all volunteers who complete two posts will be entered into a drawing to win a FREE 2016 ANNUAL MEETING REGISTRATION!

What do I need to know about Blogging?

Not much!  All volunteers will be sent AIC’s Guidelines and Blogging Tip Sheets.  Writing a good blog post can take some time but covering a just two talks is very manageable.  Here are a few things to know:

  • You do not blog in real time so you don’t need a laptop or internet access at the conference– the best way is to take notes and then write up your thoughts later (ideally by the end of the conference or shortly thereafter).
  • You need not be an experienced blogger nor particularly tech savvy.  The WordPress blog format is extremely easy to use and any necessary hand-holding will happily be provided to make you feel comfortable online.  If you can send an email – you can create a blog post.
  • There is no pressure to be particularly witty.  Active tense, first-person and personal style are all encouraged in blog posts – this is a chance to free yourself from the writing constraints of condition reports!  While all posts should be professional overall, the tone is somewhat between reporting and “what I did over my summer vacation”.  The best posts tell why you were interested in the topic and what you learned, you aren’t expected to be writing the speaker’s postprint so you don’t need to capture every detail.  The goal is for readers to learn more about the talk than they would gain from the abstract.  Tips and Guidelines will be provided for all volunteers.
  • In addition to the talks we also value reviews of the workshop, tours, receptions and other associated events and sessions.

42nd Annual Meeting – Workshop, May 28, "Responding to Mold Outbreaks after a Disaster"

This full-day workshop comprised 4 talks by 3 conservators, all experienced with treating mold affected artworks or library/archive materials. The morning session was presented by Olivia Primanis, Senior Conservator at the Harry Ransom Center, University of Texas Austin. Primanis gave a large amount of introductory material focusing on aspects of mold that are of interest to Heritage Conservators and Caretakers. An introduction to mycology provided a basic understanding of fungal characteristics and the life cycle of aspergillus, one of the mold genera most commonly found after flood events. Details of fungal anatomy such as conidia/spore sizes were also discussed, as were activators of conidia – the conditions that encourage rapid growth. Fungal genera found on artifacts, as illustrated in Mary Lou Florian’s book Fungal Facts, was also briefly discussed. Primanis also discussed whether it was necessary to consult with fungal experts, such as industrial hygenists, who can take samples and identify the mold species. While species identification may inform mitigation treatments, it appeared that the presenter did not do any species identification during any of the case studies presented, and all mold outbreaks were treated using the same method of HEPA vacuuming to remove the visible mold, in some cases followed by attempts to neutralize the remaining microscopic elements using a 70% ethanol solution. Rather than attempt to “kill” the mold, Primanis vacuums and then works to optimize the environment to stop or slow mold growth, as historic mold killing treatments have been found to either stay in the affected material and affect users, or could potentially adversely affect the object itself.
In addition to a lengthy bibliography and access to additional downloads via a shared Dropbox folder, Primanis also provided a useful list of options to consider when responding to a mold infestation:
• What is the cause of mold growth and how can the growth be stopped?
• Should an expert, such as an industrial hygienist, be consulted?
• Should the type of mold and bacteria be identified?
• Should the mold be killed?
• What are the health and safety issues for staff and patron?
• Should the mold, and can the mold, be removed from affected building materials and artifacts?
o What methods can be used to remove the mold contamination?
o What methods can be used to assure the cleaning process has been effective?
o What will access to building and collection materials be?
The second presentation was by Ann Frellsen, Book and Paper Collections Conservator for the Emory University Libraries, a member of AIC-CERT as well as organizer of HERA (Heritage Emergency Response Alliance) in Atlanta, GA. Frellson discussed AIC-CERT response after Hurricane Katrina as well as HERA regional response activities, presenting a variety of challenges through a series of case studies. Response activities after tornado destruction in Atlanta highlighted challenges in establishing salvage priorities, as the emotionally affected owners of the collection were incapable of making those decisions, as well as communication issues. Post-Katrina AIC-CERT response inside a historic house on the Gulf coast illustrated the essential need for proper PPE, in this case including full HAZMAT suits equipped with a forced-air system. Another case study discussed how affected town record ledgers containing property data needed to remain accessible, as people were required to consult them in order to obtain proof of ownership as required by their insurance companies. A mold event at Emory University discussed the need for managing contracts with salvage companies, emphasizing that their activities may need to be closely monitored, and you need to know exactly what you want from them.
Ann Frellsen and Vicki Lee (Director of Preservation and Conservation at the Maryland State Archives and AIC-CERT member) teamed up to give a short case-study presentation cleverly titled: “Where We Did Not Find Mold, or, I Suited Up for This?” This presentation consisted of a series of images from flood/water response activities that provided the ideal circumstances for rampant mold growth (such as wet photos in plastic sleeves, wet salvage items left covered in plastic, and wet basement library items relocated to a non-climate controlled backyard shed), but exhibited no visible mold growth.
Another short presentation, titled “Creative Solutions: Thinking Outside the Box (the boxes have not shipped yet)”, presented examples of stabilization treatment ideas that developed from specific needs, such as the creation of a quick-fix solvent chamber at the Cultural Recovery Center in Brooklyn (post Hurricane Sandy) in which solvent sensitive moldy artifacts were treated by placing them in a Ziploc bag with solvent soaked cotton balls overnight. The efficacy of the treatment was not determined. Another attempt to wash and deacidify a paper item tried using crushed and strained calcium vitamins in an attempt to develop a buffering solution bath – the pH was tested at ~pH 7.5. This may be because calcium vitamins comprise calcium carbonate, not calcium hydroxide, but perhaps there were some other steps involved in the experiment that were not mentioned.
Questions from the audience:
Q. How effective is spraying an alcohol solution, when papers are general soaked in baths for 30 min?
Answer from Presenter: No testing was done to determine effectiveness, but it visually appeared to work.
Answer from Audience member: Alcohol treatment only kills surface mold via dehydration. To kill the fungal organism inside of the object or paper fibers, it needs to be put in an anoxic environment for at least 5 weeks using CO2 or Argon gas, which ruptures the cells. If you don’t kill all of the mold (not just the surface mold), then you will have dormant mold under the upper structure.
Q. Was it worth spraying then?
A. Yes, because it minimizes the spread of the spores. You can potentially maintain dormancy by controlling the environment (if possible).
Q. Should you spray, vacuum, and spray again? Vacuum, spray, vacuum?
A. Generally, spray, vac, spray, unless obviously very dirty, then vacuum first so that you can access more of the surface mold.

42nd Annual Meeting – Conservators in Private Practice, May 28, "Greening your Conservation Practice."

Believing heat wheels work is like believing you can section off a part of a hot tub for peeing.

Headline speaker Monona Rossol began this year’s CIPP workshop with her characteristic flair when referring to the use of the heat exchange system with contaminated air streams. The system is often recommended to score points for Leadership in Energy & Environmental Design (LEED) certification and served as an example of how greener practices may not necessarily be safer practices.  An Industrial Hygienist and health and safety champion for the arts community, Monona is the founder of Arts, Crafts and Theater Safety (ACTS). If you don’t leave one of her lectures concerned about everything you have ever come in contact with, you should at the very least have a better idea of how to navigate your way through the jargon of government, industry and product health and safety information.
The beginning of Monona’s talk introduced the pitfalls of blindly accepting the safety information provided by government regulatory organizations and manufacturers. In her explanation of many of the acronyms associated with chemical classifications and exposure assessments, Monona emphasized that it’s what we don’t know about chemicals that is the most concerning. For example, phrases such as “not listed as a carcinogen” and “generally recognized as safe” do not indicate that the chemical is not toxic, but may mean that it has never been tested. She also reviewed the improved chemical labeling and Safety Data Sheets (SDSs), as outlined by the new OSHA Hazard Communication Standard. Even though SDSs are better than their predecessors, Material Safety Data Sheets (MSDSs), they still are limited by lack of information. Finally, she discussed commercially manipulated and undefined “green” phrases like all natural–just because something comes from nature does not make it is safe–and biodegradable– chemicals can breakdown into compounds that can be more toxic than what you started with.
So what can we do as conservators and consumers to protect ourselves, the others we work with and the environment?

  • Become a conscientious and informed user; understand and learn about the products in your studio as well as the language and limitations of hazard communication (such as manufacturer provided SDSs) and local and federal regulations.
  • Purchase products from companies that disclose the full ingredient lists and avoid products that have proprietary formulations.
  • Support laws such as California’s PROP 65, which requires the state to publish a list of toxic chemicals. Businesses must notify Californians about significant amounts of chemicals in their products or that are released into the environment. By allowing anyone “acting in the public interest” to enforce the law, it takes the responsibility for policing manufacturers and their harmful materials out of the hands of legislators and bureaucrats and into the hands of the people who are being affected by toxic chemicals (you!).

In the second half of her presentation, Monona discussed air quality and fume and particle extraction. She first reviewed the definitions of gases, vapors, fumes, dusts, mists, nano-particles and smokes; their associated health hazards; and types of filters that can be used. In her discussion of fume extraction, she cautioned that window fans and air conditioners are not proper ventilation and of the limited efficacy of portable, filter-based fume extractors. Her main point was that proper extraction involves a displacement system that exhausts to the exterior in concert with bringing in uncontaminated air from a source on a wall across from the exhaust (not from an adjacent wall or window). A clear path of air flow should put the conservator’s head directly in the stream. Filter-based extractors can be selective to the vapors and/or particles sizes they collect; only clear the immediate work area; do not provide clean replacement air; and have no indication of when the filter is no longer functioning properly. She stressed that when you are designing your ventilation system, you should consult a specialist with an industrial ventilation background. While there were too many points to discuss in a few hour workshop and certainly too many to adequately cover in a blog, Monona is always willing to respond to anyone’s concerns or review your studio set-up.
 


 
The remainder of the session focused on greener business practices. Chair of the Committee on Sustainability, Betsy Haude, outlined the committee’s activities over the past year, including several AIC News articles and making their wiki into an informative and useful resource.
Objects Conservator Sarah Nunberg, followed up with an outline of the results of a Life Cycle Assessment to look at the environmental impact of museum practices. Conducted in collaboration with the Boston Museum of Fine Arts, students at Northeastern University performed four case studies using a computer program with a series of user defined parameters:  1) halogen vs. LED lighting, 2) solvents used for consolidation of stone, 3) loans and transport, and 4) HVAC systems. They concluded that the LED lighting was more energy efficient. In the second case, silane in ethanol proved to have the greatest negative environmental impact over B72 in xylene and B72 in acetone and ethanol; xylene had a greater impact than acetone/ethanol primarily due to its production. In their loan assessment they compared a loan going to Tampa, Florida and a loan going to Japan. Interestingly, they discovered that accommodating for the courier had the greatest environmental impact. Finally, their study also showed that shutting down HVAC systems every night decreased the energy costs by 40%, but that the overall energy impact also depended on the source. Seeing quantified data on these various museum conditions allows for a discussion on how museums can potentially reduce their environmental impact, while still considering the elements of maintaining and promoting their collections.
The final three San Francisco-based speakers discussed the various programs that are available for greening business in California.  Wendy Yeung of the California Green Development Program presented on how this government program works with local business to implement environmental protocols that are both sustainable and profitable. Anya Deepak, a Commercial Toxics Reduction Associate with the San Francisco Department of the Environment, discussed their program for artists, which is an outreach initiative to raise awareness among Bay Area artists on environmental and health issues associated with their art materials. The program is currently in the first phase of implementation and will eventually address disposal, safety and finding alternatives. Organizers discovered they were able to get remarkable participation and interest from all the studios they contacted by suggesting that the artists could have an effect on the environment by following these practices–a notably more positive response than when they tried to appeal to the artist’s personal health and safety. Finally, Anna Jaeger from Caravan Studios, a division of TechSoup Global, discussed various electronic and tech-based programs for greener business administration. Her examples focused on the idea that it is more effective to change the situation or environment than to change an individual’s behavior. Tips included using smart power strips and multi-function machines; conducting virtual meetings; and purchasing refurbished electronics since the majority of energy use goes into their production.
The seminar concluded with a group discussion of what sustainability means to us and the field of conservation. Can artifact preservation and environmental preservation coexist? How can we make the annual meeting more sustainable? Should ventilation regulations focus on optimal human performance within that space or optimal environmental impact?

42nd Annual Meeting – Angels Project, June 1, California Historical Society


This year’s Angels Project took place at the California Historical Society (CHS), a non-profit organization founded in 1871 to celebrate California’s rich history. Textile conservator Meg Geiss-Mooney and photograph conservator Gawain Weaver led the group of about 25 enthusiastic volunteers and had our project and supplies ready to go early Sunday morning.
Prior to the AIC meeting, Gawain had surveyed the CHS collection for approximately 200 photograph albums that were in need of treatment and/or re-housing. We divided up into teams based on specialty and skill set, and went to work to assess, surface clean, stabilize, and box each album. The library was organized into stations to help with workflow and I joined the group that was examining each album to identify the photographic processes and provide recommendations for treatment. Not only was this a great way for me to put my photo conservation skills to the test, but as a native Californian, it was a pleasure to look through these beautiful albums featuring historic images of local monuments and people. Using a pre-made single page survey form, we denoted all necessary identification and condition information to help with the following treatment steps and for later catalogers at CHS.
Station two began treatment, and was set up to vacuum, brush, and clean with eraser crumbs the dirtiest album covers and pages. A special table of volunteers was armed with the proper PPE to tackle any possible mold. Next, a group of expert conservators were completing treatment steps such as re-attaching loose photographs, mending torn pages, and tape removal, as needed on a case-by-case basis. Finally, the albums were whisked away to be housed in new archival-quality boxes that were labeled and placed on a cart to return to storage.
At the end of the day, all albums were assessed and boxed, and many received significant treatment steps that will no doubt prolong the life of these valuable objects. For those albums that did not receive treatment, they can be flagged by priority and sent out to a private conservator in the future. As with Angels Projects that I’ve participated in in the past, I appreciated the opportunity to meet, learn from, and work with many new conservation professionals, and I was especially happy that this project allowed me to directly benefit the photographic collection through treatment and re-housing.
Many thanks to Meg, Gawain, Ruth Seyler, and the rest of the AIC staff for organizing this year’s project, and to the CHS staff for generously providing the volunteers with ample working space and supplies, a delicious lunch, and a bonus free annual membership to the Society!

42nd Annual Meeting – Workshop, May 28, 2014, “Dataloggers – Establishing and Maintaining Environmental Monitoring Systems” by Rachael Perkins Arenstein and Samantha Alderson

This workshop was a smorgasbord of dataloggers, filled with details about how they function, how the recorded information is moved from one device to another to be analyzed and repurposed, and how to think about choosing the right type of datalogger to match a particular environmental goal. I came into the workshop hoping to learn about new equipment that’s on the market now, to advance my institution’s upcoming project to re-invigorate our environmental monitoring and control program, in support of both energy and preservation goals. I got what I came for!

Samantha Alderson and Suzanne Hargrove discussing datalogger options

The workshop was taught by Samantha Alderson and Rachael Perkins Arenstein, both of whom have advised institutions large and small about environmental monitoring programs, and clearly know what they are talking about. They recently updated the National Park Service Conserve-O-Gram (“Comparing Temperature and Relative Humidity Dataloggers for Museum Monitoring,” September 2011, Number 3/3, http://www.nps.gov/museum/publications/conserveogram/03-03.pdf ), which is worth reviewing, but with the caveat that the technology is changing so rapidly that vendors and specifications should be researched anew when you’re planning for a major purchase.
The presenters started by reviewing basics of the hardware and connectivity, summarizing what kind of data loggers can collect, how many loggers one needs, and where to place them, and for how long. They also talked about general environmental management concepts so the less experienced in the audience wouldn’t be left behind.
They then explained a basic difference between two families of dataloggers:

  • Stand-Alone Loggers collect data which is then harvested either by direct wired connection to a computer, through an indirect intermediary device like a card reader or thumb drive, or wirelessly; this method is appropriate when you don’t need real-time data
  • Connected Loggers either wired (Ethernet) or wireless (radio, WiFi, cellular, etc.) transmit data to a receiver that then aggregates the data from one or more devices; this method is appropriate when you need real-time data, need to receive alerts, and when you need to manage a lot of devices

Other topics covered included datalogger software and data management, calibration, and a group activity in which we had to choose (and justify) a monitoring system for one or more specific scenarios. This activity was my favorite part of the workshop, and I wish we had spent more time on this. It was a practical test of how to figure out why and what you need to monitor, and how to maximize your resources to achieve that goal.
Helpful handouts included charts of various datalogger models/systems with comparison of many variables including costs. Options to consider include: connectivity, size and aesthetics of the logger, battery type and life, sensor quality, data capacity, cost, accessibility of the device once installed, built-in display of current readings, display and/or communicate alarms, sampling rate, calibration method, probe option, and software platform compatability.
Here are some take-aways that for me will inform my upcoming work:

  • The landscape of available hardware is rapidly changing with developments in communications technologies; Bluetooth is the hot technology according to several vendors, so they are investing their development efforts into Bluetooth connectivity for their upcoming upgrades and new releases
  • Sensor quality matters, but there are also differences (reflected in the wide range of prices) in everything else around the sensor…most notably the architecture of the device, the circuitry and algorithms used to translate the sensor data into numbers. You get what you pay for, but that should be matched to what you need.
  • Sensors are very sensitive to organic vapors! They can be destroyed by a big whiff of solvents, and even thrown off by off-gassing from the plastic housing in which they are mounted.
  • Loggers need to be checked for accuracy (you can do this yourself with saturated salt solutions according to instructions in another helpful handout), and if they have drifted, they need to be recalibrated (some you can do yourself, others have to be sent to the manufacturer); battery replacement is also variable (some are DIY, others not).
  • Most connected loggers require IT support for installation in an institution, so include your IT staff during the planning phase; be sure to ask them about WiFi encryption requirements
  • Wireless technologies may be affected by building/exhibit case material and construction, as well as nearby noise-emitting sources
  • Software varies a lot, but some of the systems can import data from other manufacturers’ devices; again, you get what you pay for, but the options I favor include the ability to import climatic data, graphical visualization of the data in a format that’s understandable by a range of audiences, and good tech support.

At many points throughout the Collections-Care focused Annual Meeting, I noticed that careful environmental monitoring and interpretation of the data becomes a fundamental part of energy savings and decision-making, grant-funding and construction/renovation of storage spaces. I almost wish the workshop had happened right after the meeting instead of before, because I would have had many more big-picture questions to ask of the presenters. Mostly, I want to hear a more substantive discussion about why we monitor, and how to translate the data into words that advance preservation priorities. Environmental monitoring is a time- and resource-intensive process, so we should be thoughtful and strategic about it.

42nd Annual Meeting – Opening Reception, May 29, de Young Museum

This year’s opening reception for the 42 Annual Meeting was held at the de Young Museum.  The museum is located in Golden Gate Park, and the venue, surrounding area, and reception did not disappoint.  The museum provided a great place for the conference attendees to meet up with friends and colleagues, meet new professionals in the field and just have fun after a full day at the conference.
Not only was it a great atmosphere for socializing, but the food and drink did not disappoint.  For you foodies out there, the grub at the reception was amazing!  But then that seemed to be the theme of the day with delicious pastries and baked goods offered at both coffee breaks earlier in the day.  Check out some pictures from the reception below.  And a warning…most are of the food, because it was that good!
 

Everyone lines up at the end of the first day of the annual meeting to board buses to the De Young for the opening reception.

There was sushi as well as a noodle dish served in small take-out containers (very cute!)

Very large bamboo steamers filled with different types of dumplings were set up on some tables.

So much food…cheese, quiche, vegetable paninis, pasta, chicken satay, mash potatoes and a meat station!

This would certainly be a conservation challenge! On display in the area of the reception  were these amazing hats and costumes were part of an exhibit celebrating 40 years of the revue "Beach Blanket Babylon".

This Opening Reception was definitely a great way to kick off #AICSF and I can’t wait for next year’s reception in Miami!

42nd Annual Meeting, Workshop Session, May 28, 'Essentials of Inpainting' by James Bernstein.

The Essentials of Inpainting workshop was well attended and greeted by a very welcoming James Bernstein adorned in wonderful kilt regalia. The one day workshop was presented predominantly through power-point presentation with plenty of interaction and discussion with the participants. The main head table was packed with portable workstation blocks holding a huge array of color pigments. The workstations were made from Ethafoam® and were light-weight and versatile. Examples of fillers were also available to examine which emphasized the essence of choice and considerations when thinking about filling and inpainting surfaces.
The day focused on practical application rather than ethical considerations due to time limits and varying contexts that conservators work within. A great booklet full of useful handouts which echoed the content of the presentation was provided from the start which helped prevent excessive note taking and increased knowledge transfer throughout the day. The booklet provided a summary of the content of the workshop; materials, concepts and participants experiences which included preparation, techniques, varying reactions of the choice of media, brushes, study of pigments, paints and their properties, toning and patination and in-painting standards. Complementary material relating to the presentation was included which was thorough in content which really helps with later revision.
James reminded the delegates of the importance of establishing a sense of the character of the object and all layers beneath the paint film need to be evaluated as all these elements effect one another. When thinking about inpainting, wicking and capillary actions need to be controlled and identifying inherent and altered states needs to be deciphered. These were just many of the considerations taken into account when trying to approach inpainting on various surfaces. Good support during treatment application was considered essential to enable good control. Painting sticks, plexi blocks and rolls were other alternatives if working with other substrates. Having a well organized and labeled pigment selection was highly recommended along with strong light and magnification.
Fill material and techniques were discussed and the importance of isolating areas requiring infilling to reduce the risk of leeching of binders. James spent a lot of time explaining the varying techniques to apply fill material to enable good inpainting. I particularly enjoyed learning about the use of cellulose fibers as they were compatible with cellulose materials such as canvas, paper and other organic objects. The material is inert and is easy to remove. Solka-Floc® was used as an example of Microcellulose Purified Cellulose fibers available in varying fiber lengths which can be used with the adhesive/consolidant of your choice. Differing techniques regarding reversibility of inpainting was also discussed such as how the Getty Conservation Institute use tissue overlays as an isolating method and as a form of reversibility. Drying time and shrinkage of fill material was considered an issue; if the fill is not applied well they have a tendency to sink in the center due to the material drying from the outside in, leaving the center to dry last. Applying the fill as thickly as possible will aid in less shrinkage, which is another common challenge with fills. James explained the effects of fill materials on inpainting through a failed project he had completed some time ago which highlighted how an incorrect fill could be detrimental to the inpainting applied. This was a great lesson. James presented all kinds of techniques with regards to good lighting, burnishing and smoothing.
Color and pigments were reported which led to a reminder of the color theory and pigment indexing. It was rather rewarding as a textile conservator to learn James is more fearful of dyes than pigments which really emphasized the complexity of dyed textile substrates in comparison to the complexities of pigmented paint film. The potential for dyes to migrate and bleed is a very real one and control can be difficult. Refraction and transmission of light were covered, as were issues surrounding whites, inerts pigments and black pigments. These can be difficult pigments to manipulate and a comprehensive pigment and particle chart was supplied which included health concerns.
The session progressed onto binders and polymers and the effects of low and high molecular weights with regards penetration. James advised to always check the composition of pigments, just because pigments have been selected for conservation use, it does not mean it is safe. Building up color slowly is essential to help with replication.
When first I realized the amount of information which was being packed into this one day workshop I thought the day would be too overwhelming. I was pleasantly surprised as to how much I actually understood due to the steady and consistent pace James presented his expertise. The handbook was incredibly comprehensive and James is very approachable as an instructor, both not just essential to inpainting but to training and developing.
