Kenneth Spencer Research Library

The Kenneth Spencer Research Library holds a rare 14th century Korean Buddhist sutra (MS D23) titled, Dae Bangwangbul Hwaeomgyeong (The Sutra of Garland Flower of Great Square and Broad World of Buddha). The sutra is the 45th volume of the eightieth version of the Avatamsaka Sutra translated by Siksananda between 695 and 699 in the Tang dynasty (Eung-Chon Choi, 2003). It is mounted in accordion book format, a practice commonly seen in China, Japan, and Korea (Hsin-Chen Tsai, 2017).

The sutra’s structure consists of papers with a width of 101 cm and height of 26.7 cm that are joined by one seam every nine pages with a starch-based adhesive[1]. The sutra has sixty-one pages of text comprising three chapters, and four pages on which is painted the frontispiece. The calligraphy and frontispiece are hand-painted in a metallic media, likely gold, where gold pigment is typically mixed with animal glue as the binding media (Hsin-Chem Tsai, 2017). The outer edges of the text block are also decorated in gold. The heads, chest, and hands of the three Buddhas in the frontispiece are further enhanced with cream, red, blue, and black opaque paint. The verso of the sutra is blank except for inscriptions along the seam of each join labeling each section.

There are four different papers observed throughout the sutra. The text block of the sutra is a double layer of dark blue dyed paper, likely indigo, that is highly burnished. The paper used on the verso of the frontispiece, back cover, and adjacent pages is a different laminated indigo paper. It is not burnished, and the indigo has prominent brush strokes (see Image 2). The paper cover has a white paper core consisting of a few sheets laminated together and is covered with a thin, blue paper. The front cover is decorated with flakes of gold leaf while the back blue paper cover is blank. Fiber identification characterized the furnish (fiber content) of these papers as a paper mulberry or a paper mulberry mixture with either mitsumata or gampi. These fibers are consistent with the known furnish of papers from this period and region.

According to Goryeo dynasty: Korea’s age of enlightenment, 918-1392, the following volumes from this set of Avatamsaka Sutra are extant and share the same style of calligraphy, treatment of the frontispiece, and cover design: Vol. 1 (private collection in Japan), Vol. 4 (Tokugawa Art Museum), Vols. 35 and 36 (Yamato Bunkakan), Vol. 42 (Tsaian-ji, Kobe), and Vol. 78 (The Cleveland Museum of Art). 

The sutra had several structural issues (weak folds, insect damage, old mends that were detaching) and was a priority for examination and treatment to stabilize it for future use. With great thanks to the Andrew W. Mellon Foundation and its support of a Collaborative Conservation Initiative at KU, there was allocated funding to host a visiting conservator to complete a special week-long project during the grant period. We reached out to Minah Song, a conservator in private practice in the Washington D.C. area, to advise on the development of a treatment plan for this rare object. Read more about Minah’s entire Visiting Conservator Project in the blog post written by Special Collections Conservator, Angela Andres.

After the sutra was examined and the condition issues prioritized, we shared our observations and treatment plan with Elspeth Healey, special collections librarian, who authorized the treatment. Our plan included addressing all necessary mending needs first. If we could tone a good matching paper, then we would also address the most visually distracting mends and overlays to reintegrate the paper margins of the sutra. We toned handmade Korean paper (hanji) using High Flow Golden acrylic paint (indigo/anthraquinone) and Dr. Ph. Martin’s Synchromatic Transparent watercolor (black) diluted with deionized water to mix various blue tones and achieve a good match with the sutra’s burnished indigo paper. The mixture was brush-applied to the hanji and the paper was hung to dry completely.

Once the paper was toned, we removed old mends across worm holes that were loose and detaching. We used the new mending paper to reinforce weak fold creases and replace old mends, as needed, and reattached the seams that were coming loose. The treatment overall was kept as minimal as possible with the primary goal of stabilization so that the sutra could be safely handled. Once the new mends and infills were attached with wheat starch paste, some were locally inpainted with Schminke watercolors to match the sutra’s paper tone more closely.

The conservation treatment of the sutra is now complete. The new mends have better visual integration with the object and allow for the sutra to be safely handled. We would like to extend our sincere thanks to Minah Song for her guidance and expertise on this important project. We would also like to thank Dr. Brian Atkinson, Assistant Professor in the Department of Ecology and Evolutionary Biology and Curator of the Division of Paleobotany at the Biodiversity Institute for the use of his microscope to complete fiber identification. Finally, we would like to thank the Andrew W. Mellon Foundation for enabling this collaboration.

[1] The final section is only five pages long, including the cover, and is 55.8 cm wide. Adhesive was tested with an iodine indicator. The adhesive is likely wheat or rice starch paste.

In the first installment of this two part blog series, the Kansas artist, Mary Huntoon, was introduced. We shared how her print, Kansas City, Kansas Grain Elevators, was prepared for an overall washing treatment in order to reduce several dark brown stains along the top edge that interrupted the image area and created bulging in the surface.

Before any washing treatments are performed on works on paper, all media are tested with the proposed washing solutions to ensure their stability. The surface is also checked for any areas where the print may have been previously restored, or even re-touched by the artist with another material that might be water-soluble. I carefully examined the print under magnification during testing in order to make sure the ink and paper were safe for washing. Everything checked out, so I was ready to start the washing step.

Prior to washing, the print was gently surface-cleaned and the brown paper attachments were removed. You can read more about these steps in the first blog post about this treatment.

Before a work on paper is placed into a bath, the entire object must slowly undergo a humidification step. This helps to relax the paper and the media and prevents aggressive swelling. Then the object is gently sprayed with deionized water using a fine mist attachment in order to fully saturate it. This step-wise procedure ensures a gentle transition for the object into the bath.    

The print was washed in successive baths of pH-adjusted deionized water and air-dried. I examined the print once again to assess the progress of the washing step. The stains had noticeably lessened, but they were still quite visible, and I decided to test another stain reduction technique.

Using a small brush, I gently introduced very small applications of a dilute reducing bleach to the stained areas. This reduced the stain to an almost undetectable level. Then the bleach was fully rinsed with additional baths of pH-adjusted deionized water. I used an ultraviolet lamp to check to see that all the bleach, which fluoresces under ultraviolet radiation, was rinsed away.

After the stain reduction and overall washing was complete, it was time to address a few structural concerns. Weak creases in the upper corners made the print vulnerable to breakage and tearing, so I reinforced them using Japanese paper applied with wheat starch paste we make in our conservation lab. Instead of cutting the Japanese paper, it is wetted and torn. This torn edge makes use of the long kozo fibers in the paper and creates a strong mend that integrates well into the paper. After all the mends and reinforcements were complete, the print was humidified a second time and flattened between thick felts. Pressing between felts helped to remove planar distortions along the edges, while also maintaining the plate mark of the etching.

Now that the treatment is complete, the print is ready to be returned to the collection where it can be safely examined by visitors to the Kenneth Spencer Research Library.  

The Kenneth Spencer Research Library is home to the collection of papers and original artwork by Kansas artist and art therapist, Mary Huntoon (1896 – 1970). As part of a collaborative initiative between KU Libraries and the Spencer Museum of Art, funded by the Andrew W. Mellon Foundation, many of the prints, drawings, and watercolors by Huntoon will be treated.

The Kenneth Spencer Research Library is home to the collection of papers and original artwork by Kansas artist and art therapist, Mary Huntoon (1896-1970). As part of a collaborative initiative between KU Libraries and the Spencer Museum of Art, funded by the Andrew W. Mellon Foundation, many of the prints, drawings, and watercolors by Huntoon are being treated over the next two years.

Huntoon was born in Topeka, Kansas. After graduating from Washburn University in 1920, she studied at the Art Students League in New York City for six years under Joseph Pennell and Robert Henri, and was a good friend and colleague of William Stanley Hayter, founder of Atelier 17. She later became director of the Kansas Federal Art Project and made significant contributions to the early development of art therapy.

Kansas City, Kansas Grain Elevators, is an artist’s proof print (a print made prior to the final edition), an etching in black printing ink on cream, laid, machine-made paper. The primary condition issue involves two large brown stains along the top edge that interrupt the image area and cause distortions in the sheet. An overall washing treatment was proposed in order to reduce the appearance of the stains.

In preparation for the treatment, the printing inks were tested to ensure they would be stable during the wet treatment. The outer margins and back of the print were selectively surface-cleaned with a soft sponge, avoiding all printed areas, as well as the graphite pencil inscription. Surface-cleaning ensures that loose and embedded dirt and grime are not driven deeper into the paper support during the wet treatment.

Brown paper tape attachments on the top edge of the front and back of the print were removed with a methylcellulose poultice. The attachments had been partially removed at some point, and the top layer of the paper was slightly skinned. The poultice delivers moisture in a controlled way, softening the adhesive, and allowing safe removal of the attachment.

The print is now ready to be washed. Stay tuned for Part 2 to learn how the stains were reduced.

This is the fourteenth installment in a recurring series of posts introducing readers to the staff of Kenneth Spencer Research Library. Today’s profile features Jacinta Johnson, who joined us in January 2019. Jacinta is the Associate Paper Conservator, Mellon Initiative, and splits her time between the Kenneth Spencer Research Library and the Helen Foresman Spencer Museum of Art. Welcome, Jacinta!

Where are you from?

I grew up in the Puget Sound area of Washington State, but have lived in many other cities throughout the Pacific Northwest, California, and the East Coast.

What does your job at Spencer entail?

I joined KU Libraries’ Conservation Services Department in late January as the Associate Conservator for a three-year initiative, funded by the Andrew W. Mellon Foundation, aimed at bridging the conservation efforts of the Kenneth Spencer Research Library and the Helen Foresman Spencer Museum of Art. I specialize in paper conservation and split my time between the library and the museum, working with staff at each site to prioritize conservation projects with common goals.

What is one of the most interesting items you’ve come across in Spencer’s collections?

The collection of prints and drawings by Mary Huntoon (1896-1970). Huntoon was born in Topeka, KS and grew up knowing she wanted to be an artist. She studied at The Art Students’ League in New York and lived in Paris for five years. She returned to Kansas in 1930 and later became the state’s first art therapist. Her work, which is mostly portraiture and landscapes, depicts important people in her life and all the different places she lived and the places where she travelled. The collection contains several preparatory drawings for prints and artist’s proofs that illustrate her careful working process.

What part of your job do you like best?

The opportunity to interact closely with collections. I enjoy finding clues about the artistic process, techniques, and materials.

What are some of your favorite pastimes outside of work?

I enjoy exploring cities by bike, fumbling through knitting projects, and trying out new recipes.

What piece of advice would you offer a researcher walking into Spencer Research Library for the first time?

Be sure to utilize all the great help and guidance the staff can offer, and don’t forget to visit the current exhibition!
