Conservation Treatment: A Drawing by Sir Aston Webb

Posted on May 3, 2024 by Sarah Norris

This spring, I conducted conservation treatment on an architectural drawing from the Alexander Architectural Archives. The drawing, by British architect Sir Aston Webb, shows a late-19^th-century renovation of the Church of St. Bartholomew the Great. At over 900 years old, St. Bart’s is the oldest surviving church in London!

The drawing presented several condition issues. It was covered in a significant layer of grime, likely the result of storage in a sooty London office. The margins displayed a thick layer of brittle, cracked, brown adhesive, likely left behind by a previous display mat. Most significantly, the drawing had been executed on drawing board, a commercially-produced material that becomes acidic with age. Given the board’s deterioration, cracks and losses had occurred, and were likely to worsen with handling. The goals of treatment were to improve stability, access, and aesthetics, and to reduce likelihood of future damage.

First, the drawing was first surface cleaned with brushes and soot sponges, resulting in a notable change in contrast and legibility. Surface cleaning removed acidic components from paper’s surface to slow future pH shifts and to prepare for water-based treatment.

Next, the residual adhesive was softened with successive applications of a methyl cellulose poultice, and mechanically removed with a microspatula. Methyl cellulose is frequently used in conservation as a controlled moisture delivery method. The residual adhesive is glue made from animal hide, so it responds to water without need for more aggresive solvents.

Then, the drawing was removed from its acidic backing board. This process involved using a modified bone tool to split the drawing from its board. Remaining fibers were then pared away with a modified lifting knife while working on a light table. This process represents a major change for the item that requires justification. In this case, removing the backing significantly reduces the risk of future damage, and no significant content was on the back of the drawing.

Last, the drawing was washed on damp blotter to reduce acidity, remove degradation components, and reduce discoloration. A lining of Japanese tissue was then adhered with reversible wheat starch paste to provide ongoing flexibility and stability.

Thanks to the Alexander Architectural Archives for the opportunity to work on this drawing. I hope to visit this building in London someday!

Students Compare Flattening Methods for Tracing Paper

Posted on May 3, 2024 by Sarah Norris

This spring, my lab students had a unique opportunity to compare the effectiveness of two treatment methods. While ours was an informal observation, it was nevertheless informative for future projects!

Our class was conducting conservation treatment on a batch of rolled architectural drawings. These drawings were on tracing paper, a material that can respond unpredictably to water exposure. Unfortunately, the most effective way to flatten rolled documents is through humidification! This poses a challenge for both preservation and access.

After testing our media for water solubility, the first half of the class proceeded with humidification and flattening through one method that is fairly well accepted in paper conservation. These documents were dried between blotter paper and stiff boards, beneath weights. The resulting documents were flat for storage and handling, but slightly rippled. Could we do any better?

The second half of the class responded by using a drying method called the hard-soft sandwich. This method was developed in response to the special needs of tracing paper, in a publication by Hildegard Homburger and Barbara Korbel (see below). Differences in this method as compared to a traditional blotter stack include:

Felt instead of blotter paper as one layer of the stack.
Significantly increased weight on the stack.
Increased drying time.

And it worked!

The resulting sheets had fewer ripples in the surface, making subsequent mending of tears easier.

Though these are informal findings, this class did present a unique opportunity to compare drying methods on similar materials with similar provenance and storage history, all from the same collection. Managing such parameters on historical materials is a major challenge in conservation research. Thanks to my lab students for taking on this learning experience with me!

Students Perform Conservation Treatment on Drawings by Charles Stevens Dilbeck

Posted on January 25, 2024 by Sarah Norris

Once again this spring, we’re excited for my Introduction to Paper Conservation class to collaborate with the Alexander Architectural Archives! Students will perform conservation treatment on drawings from the Charles Stevens Dilbeck (1907 – 1990) collection. Dilbeck is best known for his residential designs in the Dallas-Fort Worth area. He created romantic cottages with French and Irish influences, as well Texas Ranch style houses. His work is documented and explored further by the Dilbeck Architecture Conservancy.

A Dilbeck drawing is unrolled for initial examination.

Drawings for treatment consist primarily of graphite on tracing paper. As the students develop introductory treatment skills, our group will work to clean, humidify and flatten, and conduct basic mends. In taking these materials from rolled storage to flat storage, we’ll improve accessibility for patrons and enhance future stability and preservation.

Disaster Response with the Institute of Classical Archaeology

Posted on October 18, 2023 by Sarah Norris

This semester, students in my Disaster Planning and Response course are lending a hand with a real-life emergency. A water leak at UT’s Institute of Classical Archaeology caused many of their library materials to become waterlogged and moldy. I joined UT Preservation Librarian Brittany Centeno on the scene, where the books had been moved to a nearby room.

Since many of the books were still wet, Brittany and I stood them on end and fanned out the pages, while a facilities manager brought a large fan to increase air circulation. This first step in water disaster response helps decrease the ongoing risk for mold growth.

Drying books — Books are dried on end, while fans (not pictured) increase air circulation.

Then came a discussion with collections caretaker Adam Rabinowitz to determine next steps. Some books were deemed replaceable; others were important to salvage, as they contained scholarship from less accessible regions. Salvage candidates were routed to Brittany’s preservation freezers to halt the progression of water damage. From there, books that were valued primarily for their informational content went for preservation scanning.

The remaining volumes came to my students for mold remediation. Working with a HEPA-filtration vacuum, soot sponges, and brushes, my students practiced their skills removing mold. We also encountered many examples of blocked pages: leaves of clay-coated paper that become irreversibly stuck together after water exposure. This offers the students real-world perspective on what’s achievable through varying methods of disaster response.

We’re so glad for this opportunity to work with Adam and Brittany as our students prepare for their own careers as librarians, archivists, and preservation professionals!

Conservation Treatment: McDonald Observatory Drawing

Posted on May 9, 2023 by Sarah Norris

This semester, I was pleased to conduct conservation treatment on an architectural drawing of the McDonald Observatory, a leading center for astronomical research and teaching located in the Davis Mountains of West Texas. This 25″ x 42″ charcoal and graphite drawing, made by University of Texas architects in 1934, is housed at the Alexander Architectural Archives here at the University of Texas.

The drawing had several condition issues when it entered the lab. A large tear extended up the center of the drawing, nearly separating the paper in two. The tear had been previously repaired with pressure-sensitive tape, which had become browned and embrittled over time. The tape repair was visible through the drawing’s thin tracing paper. The tear was misaligned along the tape repair, causing gaps in the image and text, as well as rippling from stress in the paper. Creases and grime had resulted from handling. The charcoal had offset during direct contact with storage materials.

Mending the tear on the light table to ensure proper alignment

During treatment, the drawing underwent surface cleaning and several rounds of humidification and flattening to reduce grime and creasing. The discolored tape was removed manually, with controlled application of moisture to soften areas of stiff adhesive. The tear was realigned and mended with heat-set tissue to minimize water exposure to the moisture-sensitive tracing paper. Wheat starch paste was added in small mended areas to improve strength.

Last, a sink mat was constructed to safely house the drawing. The deep walls of the mat hold its cover sheet away from the drawing to prevent further media offset. Acid-free corrugated board was used for structural elements to provide stiffness with minimal weight. A second ply of board, applied cross-grained, was added to support this oversize drawing.

Many thanks to the Alexander Architectural Archives for the chance to work on this beautiful drawing!

Sound and Media Artist Holland Hopson Visits Algorithmic Assemblages Exhibit

Posted on April 17, 2023 by Sarah Norris

This spring, INF 386E, Planning and Understanding Exhibits, created the exhibit Algorithmic Assemblages: Do Machines Dream of Art?.

This exhibit featured the data-based artwork A Work of Art for Every Entry in Index – Subjects – Library of Congress by sound and media artist Holland Hopson. The artwork generates descriptions of non-existent artworks by using actual Library of Congress terminology; our students then created real artworks based on these fabricated descriptions. We were so pleased to host Holland at our exhibit closing reception, and to work with him throughout the semester!

Holland also presented two talks while visiting us here at UT: “Listening as a Creative Act,” sponsored by the Bureau for Experimental Ethnography and “Data as Medium,” sponsored by UT’s Visual Arts Center. Thanks to Marina Peterson and MacKenzie Stevens for coordinating these talks, and to Holland for being our visiting artist!

Austin Edible Book Festival

Posted on April 3, 2023 by Sarah Norris

Last weekend marked the 20th anniversary of the Austin Edible Book Festival! This April Fools’ Day tradition showcases serious fun, as local bibliophiles create edible books to compete for prizes and glory.

What’s an edible book? It’s anything that’s edible, based on a book title, and likely includes a pun. Inspired by the International Edible Book Festival, Austin’s event keeps it weird by offering the unique opportunity to literally eat one’s words.

Austin Edible Book Festival is sponsored by the Austin Book Arts Center and the University of Texas Student Chapter of the Society of American Archivists. The event also featured the City of Austin Office of Sustainability, discussing their work creating a healthy and just local food system.

Student Conservation Treatments for Spring 2023

Posted on February 13, 2023 by Sarah Norris

Students in INF 393C, Introduction to Paper Conservation, are excited to apply their treatment skills to two groups of drawings from the Alexander Architectural Archives this spring! Throughout the course, students learn foundational treatment skills through work on practice materials, and then complete one full treatment on archives materials.

Roy Thomas Architectural Drawing — Student treatment project: architectural drawing by Roy Thomas for Austin’s Kealing Middle School, 1929.

The first group of tracing paper drawings features the original design for Kealing Middle School here in Austin. The plans were created by architect Roy Thomas, who designed residential, public, and commercial structures in Central Texas from the 1920s – 1950s. Kealing opened in 1930 as the first junior high for African American students in Austin. The school closed in 1971 during desegregation. The original building was razed after a fire in 1983, and Kealing’s current building opened in 1986.

Nicholas Clayton Architectural Drawing — Student treatment project: architectural drawing by Nicholas Clayton for a public school building in Galveston, TX, ca. 1898.

The second group of tracing paper drawings features a number of Galveston buildings designed by architect Nicholas Clayton. Clayton was one of the first professional architects to become established in Texas. He’s best known for his work in Galveston between 1873 – 1900, during that city’s heyday as a center of trade and commerce, and the largest city in Texas. It is likely that the water damage on the students’ drawings came from the Galveston Hurricane of 1900, still the most deadly natural disaster in US history.

We are so pleased to work once again with the Alexander Architectural Archives on these hands-on student experiences!
