A simple vacuum revolution

 I have recently had an 'Aha!' moment. I have always struggled with the small attachment tool for vacuuming. Untill now!

You know that wonderful, handy and inexpensive micro-tool that comes with the many small changeable tools. I realize that part of my struggle when using it, was the narrow-long plastic tube that linked the small attachment brush to the vacuum cleaner connection. It always seemed like I needed a third hand,  because two hands were needed to manipulate the tubes, but one was still needed for the tweezers, the micro-tool and the like.

Why does this narrow tube need to be so long, I thought? Really a new thought. The innovation is just to  cut the tube. So I did this, and Voila! Now less of the tube to manipulate, it simply connects the two sections of the micro-tool. Now, one hand is free to hold the vacuum attachment and the other for other tools that I might need, such as tweezers.

Happy New Year!

As we come to the end of 2018, we take a moment to look back at the year. The projects completed and history preserved. The new and interesting places work has taken us this last year. From leading a magnets workshop at Dartmouth to assisting with the hurricane aftermath in Puerto Rico, even multiple trips across the Atlantic to present at conferences. 2018 has been a wonderfully busy year at Spicer Art Conservation.

For our traditional holiday card this year we featured pictures from some of the many items that were treated in the studio this year, including a signed print by Victor Vasarely and a portrait of Mr. Albert N. Briggs. The lovely 1909 Wedding Dress was restored to its former beauty and packed so it will last for many more generations and a silk souvenir from the 1893 World’s Columbian Exposition in Chicago was framed for display. Fire damaged items often make their way into the studio to be cleaned and repaired, such as the painted Norwegian bench which after cleaning was stunning in its color and style.

The summer of 2018 also saw a 1910 Stoddard-Dayton Limousine brought into the studio for work on the interior upholstery. To read more about this treatment check out the blog that written shortly after the treatment was completed.

Finally, when not hard at work in the studio treating objects, Gwen was busy putting the finishing touches on her new book, Magnetic Mounting Systems for Museums & Cultural Institutions, which will be out in early 2019. As a part of her continuing work with magnets, Gwen took many trips this past year, hosting workshops and presenting at different conferences both here and abroad. In her “spare time” she also went down to Puerto Rico to assist with the post hurricane damage assessment of their cultural heritage.

We hope you have enjoyed this little look back at 2018 with us and while we look forward to another exiting and fun filled year, we wish you a wonderful 2019!

A Low-Tech Treatment for Small Areas of Visible Mold

The humidity many of us have experienced this summer due to torrential rains and heat sweeping across the country can easily lead to mold growth. Now in the wake of Hurricane Florence mold will be rampant as the flooding recedes. (For more on freezing see our earlier post.) It's important to be vigilant by monitoring humidity levels throughout your institution or home to prevent excessive moisture levels. Mold is not only a hazard for objects, it's also a danger to people.

If you've got a big mold problem, first fix the source of it and then call in professionals to remediate it. Poor drainage, foundation or wall cracks, leaking roofs or plumbing, lack of sufficient ventilation or air-conditioning all contribute to the spread of damaging mold.

If you have visible mold in less than 10 continuous square feet, you may be able to remediate it yourself with dehumidification and a low-tech water trap attached to your vacuum to capture the spores.

The water trap can be made of any glass or jar. The one we use in the studio is in the image below. It is important to ensure that it is well sealed around the openings and the tubes. Ethafoam (a strong, resilient, medium-density, closed-cell, white polyethylene foam which is acceptable for use in the preservation of objects) is really helpful for this. Gwen even carved out a stand for the glass to ensure it would not fall over. The other critical aspect is the ends of the two tubes inside the glass are above the water line. It is the vacuum's suction that forces the mold spores into the water i.e. trap, while not traveling into the vacuum cleaner.

The above photo illustrates how the water trap is connected to a vacuum. The right hand hose (with the blue end on it) is the one used to suck up the mold.

When finished, thoroughly clean all of the associated tools, mark them and save them together, including brushes.

It's very important to contain the spores, not spread them around (which is what regular vacuuming will do). Here's a step-by-step guide to what to do next and don't forget to wear an approved N95 respirator, gloves, and eye protection!

When Water Strikes, It's a Freezer to the Rescue!

Unusually warm temperatures last week have caused rivers and creeks in our area to swell, flooding low-lying areas. Earlier this winter the River Seine rose to flood stage, causing the Louvre to implement emergency protocols and close its lower level.

When a water disaster strikes a textile collection or organic collection, a humble freezer can become an institution's best friend. Subjecting items to a deep freeze will halt bacterial and fungal activity and give an institution time to develop a remediation and conservation plan. Procedures for freezing textiles should be a part of any organization's disaster plan.

No natural water disaster or leak is too small or large for a freezer to be helpful.

And the faster the response time, the better.

It is important to place the textiles into the freezer as soon as possible to minimize mold growth. Ideally, items should be wrapped in plastic with minimal folds or overlaps, thus creating a larger surface area. Interleave fabric layers with freezer or waxed paper to prevent dye transfer.

Attached labels added to the packages

Items should be spaced apart from each other to promote rapid freezing, preferable in separate packages. Insure that the package are labeled with information about the artifact, including the accession number. The more information included the better since it might be a while until they can be addressed. Do not rely on your memory of what is inside.

           

Fabric layers are separated with freezer or waxed paper 

            

Previously frozen textiles await cleaning

                         

Water damaged textiles can then be removed from a freezer and quickly wet cleaned.

In consultation with a conservator a proposal can be developed to treat the water-damaged textiles.

Great work Historic Woodstock!

It is at times like this that I truly love my job. 

I just returned from a visit to an amazing collection in a museum located in Woodstock, NY. Woodstock is known for many things, but less so for this incredible collection of artists' work consisting of paintings, prints, drawings, sculpture, textiles, photographs, books, manuscripts, film/sound recordings, antique tools, and an extensive archives of all the other arts organizations in the community.  This group had an early connection to the inclusion of artists into the WPA during the New Deal years. The Historical Society of Woodstock was founded in 1929 by a group of artists, writers, academics and local citizens. The Society maintains its link to the community of artists who are still at work in this community.

Over the years I have visited the museum many times. As early as 2008 they had already begun the project of renovating and modernizing their historic structure, the Eames House. At this time, their collection had mostly been moved to a secure location where organization and data recording was done. 

No large project like this is simple or straightforward. Always there are many moving parts. However, this dedicated group sought funding from local groups throughout New York State; NYSCA, Get Set, Ready, Go in 2009; and on the federal level, from the Federal Conservation Assessment Program (CAP) in 2010; and the National Endowment for the Humanities (NEH) in 2016. Each assessment was used as a building block that allowed them to fulfill the promise of earlier recommendations.

I want to share the great work they have done by showing a few before and after images.

insulated and painted. Now there are new insulated windows and light blocking shades.

At each visit there was always noticeable progress. 

Eames House, home of the Historic Society of Woodstock, in 2009 and 2017. The
addition positioned in a vulnerable corner provided a handicap bath room and a small kitchen.

 Eames House suffered water damage at this corner due to the sloping of the landscape,
adding to the high humidity levels inside. With the new addition, french drains were installed. 

The CAP was performed with Tilly Architects who gave them great guidance for how to improve the historic building while keeping its integrity. 

The dedicated group who did so much!  What a team.

How do I camouflage my magnets?

There is an increasing interest in the use of magnets, both in museums and among the general public. In many museum exhibits it is desirable to make the magnet blend with the artifact being mounted. Conservators and mount makers have used many methods of disguise to achieve this. A magnet or ferromagnetic material can be used and disguised quite easily (For more on what a magnetic system is, read our other posts: http://insidetheconservatorsstudio.blogspot.com/2013/05/ferrous-attraction-and-science-behind.html and http://insidetheconservatorsstudio.blogspot.com/2015/05/a-magnet-is-only-as-strong-as.html). 

The camouflaging method selected is often based on available supplies, expertise, and the experience of the practitioner. Other aspects depend on selecting a substrate similar to the artifact's texture, color, pattern and design. Concern for the durability and the magnet placement depends on the situation. In particular, the magnet's tolerance for being handled multiple times. Also, concern for its proximity to the visitor, especially in the case of patrons who might be susceptible to a magnet's effect (pacemaker wearers, for example).

Useful Tools:

If you must trim any material after it has been attached to the magnet, the use of metal tools like standard metal scissors can be frustrating because your tool and magnet are attracted to each other. Luckily tools made of zirconia (Zr, atomic number 40), like knives, are perfect and will not be attracted to a magnet. These knifes are very sharp and brittle, so great care is needed to prevent them from breaking.

Useful non-metallic tools that won't be attracted to a magnet

Below is a list of various options for camouflaging a magnet:

A) PAINT

A layer of paint can be a quick camouflaging method, but it also brings challenges. One, is creation of an uneven application (it can be difficult to apply an even coat on the plated surface of a magnet). Another, is protecting the applied surface. An added protective coating is useful to aid in reducing the potential of chipping. Another option is to "rough" the surface slightly, allowing for a better grip of the paint to the magnet surface.

The painted surface on a magnet will become chipped or marred when opposing sides are quickly snapped together. This often occurs when magnets are removed and stored, or are placed near one another during preparation when ferromagnetic materials are not present. To minimize this problem, ensure that all of the magnets for one project are stored with the poles in the same direction, so that the fragile painted layers repel each other.

This might not be a choice for magnets that are used regularly. However, it can be an easy and quick method for short term needs. To do this, place them on inexpensive plumber’s tape behind silicone Mylar, scrap steel, or a metal filling-system. (see the image below).

Using a layer of adhered paper or Japanese tissue below the paint layer can improve the cohesion. For more about painting magnets go to: http://denverartmuseum.org/article/how-dam-prepared-rare-earth-magnets-installation-oceanic-textiles

These block magnets are spaced far
enough apart to discourage them from
snapping together quickly.  

B. DIGITAL PRINT

An excellent camouflage technique is to use a digital image to duplicate the surface that the magnet covers. Larger flexible magnets are ideal for securing thin artifacts. Several conservators have published the technique, but on-line you can go to the Asian Art Museum's blog (http://www.asianart.org/exhibitions_index/batik-mounts) to read about it. 

A digital print can also be added to the outer surface of any rare-earth magnet (see photo below). 

Camouflaging is created using a long flexible magnet that
is covered with a 1:1 image of the artifact it will secure.

C. COVERING LAYER

Another approach to disguise the magnet is to apply materials that are the same, or with similar texture, as the artifact that is being supported . The materials are disguised by the color, texture or images in the local area that is being covered, or even the actual embellishment itself (see the decorative element section below). Examples of materials that have been used include Japanese paper, mat board (http://www.conservation-wiki.com/w/index.php?title=Magnet_Mounts), Nomex, fabric (http://spicerart.com/2014/12/17/hunzinger-chair-re-tufted-with-magnets), Tyvek, felt, leather, artificial rawhide, and ultra suede.

When fabric is used, using a sufficiently tight weave-structure to withstand the strength of the magnet is recommended. If the weave-structure is too loose, then the fabric weakens prematurely.

will be covered with the same red show-cover fabric, creating a 

camouflaging of the magnets.

D. DECORATIVE ELEMENT

Conservators have cited the magnet itself as the decorative element and hence requires placement above the artifact. The decorative element in this case aids in determining the size and strength of the magnet. If the magnet is replacing a missing element, then the size is predetermined. But the grade can be adjusted to better match the magnetic system.

When a magnet is securing the element to the artifact the magnet needs to have the strength for support. The element can be a range of sizes and shapes, large; and flat or small footprint and tall. A magnet must be selected that will secure the element, while also not damaging the artifact below. 

Read more about disguising magnets as decorative elements at the Asian Art Museums website: http://www.asianart.org/collections/magnet-mounts 

Decorative element secured to a costume using a magnet.

E. Embedding

A successful method of placing rare earth magnets within materials is embedding them properly. Keeping the magnets surrounded by materials aids in their longevity, by lessening the risk of demagnetization from both shock and heat. These embedded magnets or ferromagnetic materials can be placed on top or within an artifact, as well as used as a point fastener, or as continuous pressure on the artifact. 

Any three-dimensional artifact can be easily mounted and supported. The magnet or ferromagnetic material can be embedded and hidden inside. In addition, many of these systems can be reused. The wide selection of materials used are Ethafoam, pillows with batting and a baseboard, materials that are easily carved, and rigid or simple acid-free board.  Read more about creating mounts here:

(http://insidetheconservatorsstudio.blogspot.com/2013/01/creating-mounts-with-magnets-for.html)

Ferromagnetic material attached 

to an acid-free board inserted 

into the base of a wooden box.

The shape of the magnet, whether using a disc or a block, does not affect many of the methods described above. The only exception is cutting a hole into mat board. Here having a block-shaped magnet could be simpler than cutting a round hole, but a drill bit can be used.

At Spicer Art Conservation we are always interested to hear of magnet use success stories. In fact, Gwen Spicer, owner and principal conservator of SAC is busy writing a book about the use of magnets in conservation. The book features examples of successful magnet use by conservators. If you have a story or project you are particularly proud of, and would like to possibly be included with other successful magnet using conservators in the book, please share your own experience of covering and camouflaging magnets. We want to hear!

Storage for Framed Items Need to Protect the Frames.

One of the many advantages of working on-site at museums is seeing how collections are rehoused and stored. You can also see what clever solutions a museum comes up with that work with their particular situation and needs.

Several years ago, I had the opportunity to consult at the Maine Historical Society in Portland, Maine. They created wonderful protective storage for their framed collections in a closest that was underutilized because it was "out of the way". The closet space seemed perfect to be reconfigured into small segmented storage for framed artifacts. It can be described as a variation on bin storage. Bin storage for framed collections has been around for a long time and is highly recommended. And while it is a good choice, care is needed to ensure that all parts of the framed collection remain protected; This also means the frames themselves.

It is true that at times, the document or portrait is considered the important part of the artifact, consequently the frames are not sufficiently protected. Also, with large bin storage many frames can be housed in a single bin and the items can lean against one another. But most importantly; in a highly-populated bin, when one item is selected, several artifacts are handled. (reducing handling of artifacts is always good practice, read our previous post about lowering the handling of other artifacts, especially those that are wrapped or boxed). In the photo below, large bins are utilized, archival materials are used to interleaf the frames, and corners are protected with padding. A sheet of Ethafoam covers the "floor" of the bins, and it protects the bottoms of the frames.

Traditional bin storage makes great use of space. In the above
photo, notice especially the acid-free corrugated board used as
dividers and the frame corners padded in ethafoam, as well as
the ethafoam on each shelf "floor". The only drawback to large
bin storage is that several items lean against each other.

In the closet at the Maine Historical Society, the segmented spaces are evenly divided in small sections to allow only one to two framed items, perhaps three if the frames were very thin (image below). The sections are labeled for identification.

Padding with Volara sheeting is applied at both the lower and upper horizontal supports. Each framed item is sandwiched between foam-core board, which is very sturdy for interleaving. 

Each area is labeled, so the artifact you are looking for is easier
to find and therefore handling is minimized.

Here you can see the foam core board separators.

Here you can also see the padded lip of the storage opening. 

Another system using Metro International wire chrome movable units is used at the Roosevelt / Vanderbilt, National Park Service's new storage facility in Hyde Park, NY. The system is archival and it is space conscious. This system also allows for custom-sized sections for the bin. The size of the bin should be noted to determine if excessive handling or "paging" through framed items is done before the item being searched for is located. Also, is there any risk of the items being bumped from the side because the rack is accessible from both sides?

In this type of bin storage each item is separated so that
it will not be in contact with another piece.

A view of sliding framed storage. This system ensures that the frames will not be harmed because there is no risk that they will strike another frame or the hanging system itself. Vibration will occur with a system like this, so no framed item that is at risk for loss of media, like a hair wreath or a pastel, should be stored here. 

Another view of the sliding unit. This hanging storage is completely archival. It is costly and takes up
a large amount of space but the framed works are stored perfectly.

This hanging storage slides on set tracks and there is no risk for one unit hitting another.

close up of the sliding tracks from the above unit.

Another take on hanging storage. Care needs to be taken that the
frames cannot hit each other as the storage is moved. Here the units
move like the pages of a book.

A tremendous amount of hanging storage. 

This large hanging storage area is wall mounted and composed of archival components. It uses a great deal of wall space.

These framed items are placed in a hanging storage system that
is compact and thus makes great use of precious storage space.
The use of wood needs to be considered because of its acidity.

Large ornate frames like these are well suited to hanging storage.

Determining the best solution for framed storage is determined by many factors:

• Space
• Budget
• Amount of framed items needing storage
• Size of the items
• Ornateness of the frames, 
• Media used (pastels for instance should not be subjected to vibration from moving racks because the media could be dislodged from the surface of the work, causing it to fall to the bottom of the frame; see image below). 

Each institution will be different because of their unique needs. You may or may not have a wonderful little closet to retrofit, but you do know your collection and you know your storage space. Don't be afraid to think outside of the box and create the best frame storage for your institution.

Need some extra advice? An online guide of types of framed art and how they should be stored can be found through the Minnesota Historical Society. They also have wonderful guidelines for all sorts of things, check them all out. Want an expert collection care consultant to come and help you figure this out? Call an art conservator.

Collection management in museums where recommendations are being followed

Imagine the success in collection care that could be achieved if the recommendations in a site visit report or collection care report could be followed and implemented?

But for many institutions, by the time a report is deemed necessary, an overwhelmed state has already been reached. The museum staff simply may not know where to begin because the task has been labeled as "daunting". Yet, in some situations the survival of the collection, and certainly the most vulnerable items in the collection, need to be addressed or be lost.

I know, you are reading this and saying, "we are understaffed!", "we have a shoestring budget!" or, "you've never dealt with my board!"

Those are stumbling blocks, no one will deny. But implementing recommendations does not have to be an "all at once" effort, nor does it have to be "everything or nothing at all". Hence is why most recommendations are prioritized and a time-line is projected.

Success Story: The Banner Collection of the Literary and Scientific Circle of the Chautauqua Institution.
The background story is this: the Chautauqua Institution is a small community known for their short intense summer season, and many residents are seasonal only, leaving just a handful of people on-site in the off-season. Many buildings belonging to the institution are unheated in winter.

Overall of the 1947 banner with its protective covering.

The 1947 banner features a painted surface.

The Chautauqua Institution dates back to 1847. The banner collection dates to 1875 where it is known as the collection from The Normal School, then the Scientific and Literary Circle from 1882. The collection grows by one banner each year as the literary circle creates a banner to symbolize that year. Every banner since the inaugural banner is in the collection. Traditional also calls for the banners to be removed from display/storage and be marched in an annual parade.

About 15 years ago, the Institute called to consult with Spicer Art Conservation about the condition of some of the older banners that had grown quite fragile, as well as to seek advice about the building in which the banners are housed. The building, Alumni Hall, which is original to the grounds, had no basement, no insulation, no covering over the lights or windows, no heat, no dehumidification system, and no air conditioning.

Alumni Hall. Some of the banners are reproduced to be hung outside.

The first step was a survey of the collection, included in the survey report were recommendations which were classified into categories. The most urgent needs were identified to be dealt with first, followed by those which were close behind, and finally the needs that could wait. After the survey, a hands-on session was conducted to train anyone in contact with the collection how to properly handle and care for the banners.

One of the shelving units in the collection.

The all-volunteer committee was eager to learn about best practices and while they were concerned about the monumental task ahead of them, they made the decision to move forward, one recommendation at a time, and create the best possible environment for their collection.

The committee worked on each step, they budgeted for things they did not expect (like getting dehumidifiers), and they worked for a solid decade. Ten years later, the collection was reassessed. The collection was being stored, displayed and handled properly. Guidelines were in place, and the environment was being monitored constantly.

Each banner is placed on its solid support in archival shelving with an image of the banner on an identification card.

The Chautauqua Literary and Scientific Circle's (CLSC) collection of banners has become the hallmark for how to implement change and create the best storage and display environment possible for any textile collection. This past week I returned to Chautauqua for another visit to examine the collection and give a talk about the banners and this incredible story of success.

With hard work and perseverance, the entire collection has been conserved properly. If a tiny institution can do it with an all volunteer staff, anyone (who is willing) can do it too.

The banner collection of the CLSC has been featured in our blog once before. That entry is one of our most popular and most viewed. Simply titled "How to Store your Flag Part 1" it has been viewed by thousands and I invite you to view it by clicking the link. There are simple storage solutions there, and it is never to early or too late to implement proper storage.

And of course, if you need a professional conservator, reach out! No project is too big or too small for Spicer Art Conservation. We are here to help institutions, historic societies, private collectors and anyone who is interested in the care and preservation of historic textiles, banners and flags.

Preservation week and the importance of preserving artifacts

A week devoted to the preservation of cultural heritage is a wonderful week indeed! We get many phone calls and email messages asking for advice or help to care for artifacts from families and museum collections.  Sometimes, the items in question are in need of care from a professional conservator, but other times the items are just not being kept as carefully as they could.  The most frequent advice we give to those looking for proper storage and care is threefold:                          

1. Watch the temperature and relative humidity of your storage/display area.  You do not want large fluctuations in either; temperature should be between 65 and 70 degrees F, and RH should always be below 50%.  The chart below illustrates the ideal conditions for the safe-keeping of artifacts.  
2. Direct light is a NO-NO!  Keep your items out of the light. Light damage is accumulative and irreversible.  "No light" is therefore the best possible environment, especially for your paper, textile and upholstered items.  
3. Use acid-free materials to support and store your collection. 

If the only thing you can do is the three items listed above, it is a great start!  The recommendation of the above three items is always followed with the next three questions:

1. How in the world do I determine relative humidity?
2. What can I cover my windows with? OR is there a UV protecting glass I can use?
3. What is "Acid Free"?

As luck would have it, there is an answer for each of these questions.

1. Relative Humidity, temperature, and light exposure can be determined quite easily and with no great expense using a HOBO data logger.  If that is just way more than you think you need, then just keep in mind the guidelines above: between 65 and 70 degrees F and below 50% humidity.
2. Cover your windows with curtains or light blocking/filtering shades or light blocking/filtering cling-style window films.  Cover your lights with diffusers.  And use UV filtering plexiglass on your framed artifacts.  And if you want to measure what kind of light a particular room or area is receiving, you can use British Wool Fading Cards to determine that.  Bottom line = Light is bad!
3. An in-depth discussion about Acid Free materials can be found in our October 2013 blog entry entitled:  "What is Acid Free?"

ALA, the American Library Association reports that after the first comprehensive national survey in 2005 of the condition and preservation needs of the nation's collections, "it was reported that U. S. institutions hold more than 4.8 billion library items. Libraries alone hold 3 billion items (which represent 63% of the whole).  A treater trove of uncounted additional items is held by individuals, families, and communities.  These collections include books, manuscripts, photographs, prints and drawings and objects such as maps, textiles, paintings, sculptures, decorative arts, and furniture, to give a sample.  They include moving images and sound recordings that capture performing arts, oral history, and other records of creativity and history.  Digital collections are growing fast, and their formats quickly become obsolescent, if not obsolete".

The survey showed that, "some 630 million items in collecting institutions require immediate attention and care. Eighty percent of these institutions have no paid staff assigned responsibility for collections care; 22 percent have no collections care personnel at all. Some 2.6 billion items are not protected by an emergency plan. As natural disasters of recent years have taught us, these resources are in jeopardy should a disaster strike. Personal, family, and community collections are equally at risk."

And because of these statistics and the survey information, Preservation Week was born. Libraries and cultural heritage institutions are encouraged to use Preservation Week to connect with their local communities "through events, activities, and resources that highlight what we can do, individually and together, to preserve our personal and shared collections." If you couldn't attend a presentation in your community or anywhere else, here is a youtube link to ALA's past "Preservation Week" presentations, covering various topics on how to care for your collection. 

Of course, if in doubt about the way you are caring for (or storing) an item, or a collection, contact us!  We are happy to help. And if you think your item or collection falls into that category of the "630 items that require immediate attention and care," contact us sooner than later.
