The Conservation of Baskets

At Spicer Art Conservation we specialize in textiles, paper and objects. "Objects" is a broad category, but for us it is typically an object made of organic material that is difficult to treat, and so we are contacted for its conservation. We treat objects made of uncommon organic items, like: bone, skin, feather, hair, porcupine quill, horn, bark and a variety of species of grass, to name a few. Baskets, of course, are typically constructed of grass, but are also often embellished with additional items (feathers, glass beads, quills) making them a compound object, which could make them particularly complicated.

Baskets are often not alone in a collection, instead they exist in groups, sometimes very large groups.
A few years ago, Spicer Art Conservation and other conservators had a great opportunity to clean, rehouse, and condition a very large group of baskets. The collection of over 700 baskets were owned by the United States Department of the Interior.

the Interior collection.

The first portion of the DOI collection was gathered in the 1930's by the first Secretary of the Interior, Mr. Harold Ickes, who then gave them to the people of the United States. It is a little known collection, but with the now improved access and storage, more research on the collection will be made. What is evident is that within the collection are great examples of all types of baskets from North America.  Read more: http://www.doi.gov/museum/upload/Interior_Shelves_newsletter_2010_issue1.pdf

Baskets have been used by humans for 1000's of years and they have many characteristics: they are vessels, sometimes with a lid. Baskets are woven, coiled, stitched, braided, knotted or put together in creative ways which make them come together in a specific shape. Baskets are purposeful or decorative, exchanged in trade or tourism. Each of these qualities are what determines the conservation of the object.

RIGHT: The basket's form is more readable, it has its shape and the entire surface of the sweetgrass and glass beads

Many baskets come to us embedded with dirt. This is not surprising as baskets are incredibly dimensional with surfaces of "nooks and crannies". Baskets can loose their shape over time, slouching or warping below their own weight. These two concerns are addressed during the conservation treatment of a basket. First the basket is vacuumed with low suction and a brush attachment to release any loose dirt on the surface both inside and out. Next the basket is cleaned with swabs and a mild enzymatic cleaner. Stabilization occurs as the basket requires it; this can be in the form of a full internal support or refastening loose embellishments or handles.

Conserving Patton's Third Army Flag

Happy Flag Day 2017 and Happy 242nd Birthday to the US Army!  At Spicer Art Conservation we wanted to celebrate these two occasions by talking about the conservation of a historic American Army flag, General George Patton's Third Army Flag.

This flag is quite unique in that it is a textile constructed as a flag, yet it was never meant to fly.  Instead, Patton's Third Army Flag is a commemorative piece containing insignia from each of the 56 Units and Divisions of Patton's Third Army, as well as several lengths of laurel embellishments, all overlaid onto an organizational flag of the third army.  The flag was created specifically as a commemorative piece and was presented to General Patton by Major General Robert Littlejohn (who was chief quartermaster of European Theater of Operations).  The flag was given to Patton just weeks before his death on December 21, 1945.  The image below is perhaps the only photo of Patton with the flag.

Littlejohn presents the flag to Patton.  (Photo from U.S. Militaria Forum). 

The flag features some insignia or embellishments that are not part of the 3rd Army or its regiments.  Several lengths of laurel radiate from the center and create a separation between the Unit patches.  These laurel leaves are "European" in character, but quite fitting for inclusion in Patton's flag as he commanded throughout Europe and perhaps more importantly, laurel symbolizes victory.  An appropriate symbol to include in a presentation to a celebrated General who had famously been involved in victories of the WWII, from North Africa to Germany.

Creating a pressure mount for Patton's Third Army Flag:
A pressure mount is a type of framed mount for the display of a textile or paper artifact to create overall pressure to support the artifact. For textiles in particular, a pressure mount enables the artifact to be placed on a mount but with few or no stitches placed in the artifact to secure it to the mount.  The mount begins with a support panel composed of a rigid archival material, such as a honeycomb aluminum panel. The support panel is then covered with soft base layers created from needle-punched polyester batting. The batting serves as a soft surface for the artifact to rest on. The artifact is then covered with UV filtering plexiglas and it is secured within an aluminum powder coated frame; the edges of the frame are sealed to prevent dust, debris and airborne pollutants from entering the frame.

Patton's Third Army flag had been previously framed and was stitched to a heavy piece of black polyester fabric. The previously used frame was not a sealed pressure mount and therefore dust and airborne particulate entered the back of the frame to settle on the mounting fabric (see image below).

The previously used frame had allowed dust and airborne particulate to enter the back of the frame. Above, the reverse side of the mounting fabric shows the layer of dust.  Above, you can also see the extensive stitching in yellow thread used to attach the flag and fringe to its display fabric.

This flag is not flat:
A flag like this is unique in that the embroidery, insignia, and fringe create a 3-dimensional surface.  Additionally, the stitching of the various elements onto silk creates puckering between the patches and laurel.

Flag conservation, preservation, repair, mounting, framing, Patton Museum, textile conservator and flag care and preservation expert Gwen Spicer
This planar view of the flag's surface, shows the raised quality of the laurel embellishments.

The center area, where the large army "A" is located in an embroidered circle, is quite thick, with a round embroidered "A" being featured on both the obverse and reverse of the flag.  In fact, the large circle with the Third Army emblem is the only embroidery featured on the reverse side of the flag.

Paying attention to the raised embroidered areas of the flag is important for a number of reasons.  First, cleaning a surface that has texture and depth requires more attention to detail.  Second, when mounting the flag for display, if the raised areas are not supported, the weight of those areas can sag or shift as gravity takes its toll.

Building the Mount
Creating a pressure mount for a textile like Patton's Third Army Flag requires that the raised elements be supported consistently and overall with a padded surface as the base for the mount. If it had instead been placed on a hard, flat, base surface and Plexiglas was simply played over the top, it would result in the raised areas being crushed.  For a textile like this, the padding that covers the surface of the mount cannot consist of just one solid piece, instead the padding must be muli-layered, having areas cut-out of the padding to allow for the embellishments to rest into.

Textile pressure mounts for historic flags and banners are a specialty of conservator Gwen Spicer of Spicer Art Conservation, preservation, repair, conservation of antique, vintage and collectable flags.
While the pressure mount is being constructed, various layers of batting are
compiled to line up with the embellishments on the surface of the flag.  

The construction and building of the pressure mount is careful work.  The layers must align properly, and they must support, but create no additional bulk.

Patton's commemorative patch flag features some interesting construction techniques.  The fringe is affixed to the outside of the flag, this indicates that the flag was a standard issue Third Army Flag.  The unit sleeve patches were affixed with care and thought; the red patches were stitched in a blanket stitch with red thread, the blue patches with blue thread, etc. (close-up image below).

Above, the close-up image reveals the close proximity placement of the sleeve patches, as well as the decorative laurel. The attachment shows the puckering or "undulation" of the silk as the heavy pieces are are stitched to silk - a slippery and unforgiving fabric!

As the pressure mount comes together, each component must work in synchronicity.  The layering of the batting must sit properly beneath the patches and embellishments, the Plexiglas must create the right amount of support and proper pressure, but not too much pressure as to be damaging.  The layers of the frame; the base support layer, the artifact, the Plexiglas, the frame itself, all must work together and house the textile in a way that will create the best possible mount for as long as the flag is framed within it.

Each year Spicer Art Conservation assists organizations and individual collectors with their flag conservation and mounting projects.  Our expertise in the preservation of these historic artifacts has given us the opportunity to work on some of the most unique and interesting pieces of history. We are pleased to be a recognized expert in flag preservation and wish all flag enthusiasts a very happy Flag Day!  We are additionally pleased to serve the US Army in the conservation of their collection of artifacts and wish the US Army a very happy birthday!

What is Bondina? And how is it different from Reemay or Hollytex?

Visiting another art conservator is always a way to learn new things, but visiting an art conservator on another continent is always an adventure and often unexpected things are discovered. I spent a wonderful time with Carolina De Stefani at the London Metropolitan Archives in London, UK. You may know about Carolina if you have read about her involvement with the "Great Parchment Book Conservation". The reason for my visit to the Archives was to learn their technique of using magnets to flatten parchment. Their experience was broad and extensive, having many volumes of water and smoke damaged books containing pages of parchment.

In the research I have done on the use of magnets and how their use has entered the field of conservation, I have been so amazed by the fact that there were these various conservators, almost in the same year, who began to use magnets to flatten challenging parchment that could not be flattened by the more traditional methods. Each conservator had their challenges, and thus methods that resulted in developing their own techniques. However, each used resources, time allotment, and the tools on hand to solve their immediate issues. From each problem and solution found, we can only gain from their problem solving.

From my visit with Carolina, I also learned about a new material, called Bondina. I learned in my visit to both the Victoria and Albert and British Museum that this is a common material used by conservators in the United Kingdom and has many advantages.

At first impression Bondina seems to be like Hollytex, but then not. I will say it is a wonderful blend, that is somewhere between Hollytex and Reemay. Bondina, like the others, is also a non-woven material made of polyester fibers and comes in different thicknesses. 

Thick Hollytex (71g).  Photo from Conservation-by-Design.

Thinner Hollytex (34g).  Photo from Conservation-by-Design.

Bondina comes in three different weights (30, 71, and 100 grams), each with their beneficial uses. The thinner (30g) version, is very calendared and is not good for washing due to the high level of calendaring. But, it is great for covering surfaces under artifacts. Carolina used it to cover the metal surfaces when flattening the parchments.

Bondina "30" (30g).  Photo from Conservation-by-Design.

Bondina "100" (100g).  Photo from Conservation-by-Design.

The thicker version (photo immediately above), identified as "100", can be hot melted (as most likely the thinner version can be as well). This makes it good for making folders along with Mylar (Melinex). Carolina also uses it for a support with washing, very much like we would use Reemay in the United States.

I brought some Bondina home to the US. Now having samples and being able to really look at them more closely, Bondina really is an interesting "sister" of Hollytex and Reemay. I was pleased to learn that there are distributors here in the US, a google search will point you to them.

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 still at work in this community.

Over the years I have visited them 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; NYSCA, Get Set, Ready, Go in 2009; 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.

At each visit there was always noticeable progress.

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.

Spicer Art Conservation has gone solar!!

It is true. Spicer Art Conservation is now running on solar power! We are just so excited about this new event. It has been something that we have been working on for several years. There was the perfect southern exposure slop that was calling out for panels; and now it has them.

At Spicer Art Conservation we have always been energy conscious. In the studio we use many energy saving techniques; using compact fluorescent, and now the newer LED light bulbs, extra thick insulation for the walls, and shades for windows, as well as maintaining the studio environment for the collections in our care to ensure good relative humidity and proper temperatures.

Textile mounts of unusual sizes

Cultural heritage just does not come in regular sizes.

This fact can be both frustrating and interesting, especially when it comes to the mounting and display of artifacts, particularly textiles. In our modern mechanical world our lives are filled with things in pre-determined sizes and shapes; clothing comes in systematic sizes, small, medium and large, etc. Our houses are typically built in Colonial, Cape Cod, ranch (traditional, raised or split) or other blueprint with specified characteristics. But this not so for the artifacts that tell our stories. And so, mounts and storage spaces are all dictated by the unique and often non-conforming sizes of our collections.

A recent project at SAC is such an example. It is a most unusually embroidered artifact. I am not even sure if it should be singularly characterized as a sampler, or better described as a trade-persons portfolio providing examples of their handwork. Regardless of it's original purpose, it is clearly representative of a skilled needle person. We do not know if the creator is a man or woman as the artifact is signed at one end with an initial and last name and a date of 1857.

Textile conservation of Berlin work sampler featuring Bargello needlework. Conservator Gwen Spicer of Spicer Art Conservation custom mounted the unusually sized textile sampler
Here the sampler of Berlin wool work is seen after treatment. It has been mounted and framed using archival materials. The sampler's extra long size can be appreciated, stretching 12 feet, it beautifully showcases each of the 36 unique design panels and the 35 border designs between each panel.

Similar artifacts like the one above exist is several collections, it is likely that these artifacts were produced as a demonstration piece to show skill, and therefore secure work for the embroiderer. To this endeavor, this particular artifact is reinforced and protected for travel. The entire embroidery is backed with a glazed cotton that covers the reverse side, also hiding the reverse or "business side" of the stitches. The glazed cotton backing also protects it, especially while it is rolled during transport. The outer rough edges are covered with green silk ribbon and at each corner is a small bow. The green silk ribbon also provides a nice finishing touch to any presentation.

BEFORE TREATMENT: A close-up of the end of the sampler. Here, the fraying corner can be seen, along with the silk ribbon that covers the edge and creates the corner bows. This particular panel is lovely in that it captures both the needlework as well as the beadwork. 

This artifact is also unusually sized, measuring 146 inches (or just over 12 feet long), yet it is a mere 8 inches wide. It features 36 different and unique embroidery samples. No two pattern designs are alike. And while the outer black wool floral border is consistent around the entire perimeter, each pattern sample is separated by a unique dividing border of a repetitive design stitched in (see image below). While the sample designs include those worked with both glass and metal beads, the style of the vibrant wool colors is unmistakeable, referred to as "Berlin wool work", or just simply, "Berlin work". The panels feature much more than "standard" Berlin work, it also includes a mixture of cross stitches, Blackwork insets, and several Bargello needlework panels (see image below), some panels are embellished with glass and metal steel beads. As well as a mixture of both wool and silk threads. Such an artwork! It begs the question, who was the owner? Who did they present it to? Were they successful at their trade?

One of the several Bargello panels featuring the beautiful
brightly colored wool yarns. Here, two of the dividing
border patterns can be seen as well. 

After it was done being used as a demonstration piece for earning a living, no doubt someone saw the beauty in the piece and it became decoration. Following examination, we learned that it had been mounted previously. Signs of thumb tacks and nails were present along the twelve foot long sides of the embroidery.

The prepared mount was unusual, 150" long and only 9" wide. The owner wanted to have it span the entire upper wall "frieze" area of a room with a high ceiling.  

We are often asked what goes in to creating a mount that is both constructed of materials that are archival, and preferred among conservators, as well as museum professionals to ensure that the mount materials are safe and will not harm the artifacts they hold.

The structure of the mount is multi-layered. At its base is a support which is created from an aluminum honeycomb panel which will not release harmful pollutants, is buffered against acid migration, is not prone to warping, and is light weight (which is a wonderful characteristic when you are creating a large mount that could be tremendously heavy!). Over it is a layer of soft material, typically polyester batting. Then, over that is a mounting fabric, chosen to blend best with the artifact, composed of plain weave long-fibered cotton. The textile is then carefully attached to the mount using fine thread and stitches that follow former or existing stitching so as to not create additional holes (see illustration above). At the perimeter of the mount is the fillet, which creates the space (between the mount and the UV filtering Plexiglas) for the textile to rest. The frame of the mount is constructed of aluminum and is powder coated in any color, but typically black is the color of choice. Smaller mounted items can have a decorative frame placed over the top of the aluminum frame of the mount. The mount is completed with UV filtering Plexiglas. Plexiglas is much lighter than glass and it does not shatter like glass. Depending on the mount, the hanging mechanism is often incorporated into the back (see image below).

The reverse of the mount, with hanging mechanism.

Here at Spicer Art Conservation, we mount a lot of flags and other items that all tend to be closer to being square or a "reasonable rectangle". But to have a mount with this odd proportion is not just unusual, but also fun. The studio's work tables get moved around to accommodate the extra long size and then we begin to think about methods that might be slightly out of the standard. This is all great fun; we welcome and embrace the challenging mount and unusual textiles at SAC.

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.

ferromagnetic knives are not a good choice when working with magnets. Choose one of these non-metallic tools instead. Magnet mounts in art conservation with Spicer Art Conservation, Upstate New York
Useful non-metallic tools that won't be attracted to a magnet

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

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

storing magnets for use in conservation mounting and museum display. this quick snapping together can damage the magnet and hurt your fingers too. At Spicer Art Conservation we work extensively with magnets to create innovative treatments.
These block magnets are spaced far
enough apart to discourage them from
snapping together quickly.  

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.

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.
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:

Magnetic exhibit and display is possible with a variety of applications of a magnetic system. Here, the magnetic system is used within the artifact. The application is fully reversible, will not harm the artifact, and is reusable.
Ferromagnetic material attached 
to an acid-free board inserted 
into the base of a wooden box.

Magnetic systems for mounting and conserving artifacts can be complicated, but with some knowledge, any conservator or mount maker can create a great magnetic system.

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!

Gwen Spicer is a conservator in private practice. Spicer Art Conservation specializes in the conservation of textiles, objects, and works of art on paper. Ms. Spicer is known for her innovative treatments and mounts using magnets.
