This spring, I was pleased to work with a folder of materials from UT’s Alexander Architectural Archives. These materials came from the Boone Powell collection. Powell was a 20th-century Texas architect with notable work in Austin and San Antonio. He was project architect for the Tower of the Americas; in 1968, this was the tallest observation tower in the Western Hemisphere. This folder details his 1981-83 designs for the Texas Republic Bank and associated office buildings in San Antonio.
The most delicate part of this treatment was four sheets of photographic slides that had been stored in non-archival plastic protectors. The protector sheets had discolored and warped, and had stuck to the photos’ image areas. Working with magnification, and alternating between transmitted and raking light, I used a microspatula to mechanically release the slides from the plastic sheets. I then used gentle brushes and a soot sponge to remove adhered grime, and stored the slides in new protector sheets made of archival PET plastic.
We were fortunate that this treatment didn’t require heat, cold, or humidification, which might have required consultation with a photo conservator! When storing photographic slides at home, similar damage can often be avoided by using archival-quality sleeves or PET, Mylar, of Melinex plastic; and storing materials in conditions controlled for human comfort (no attics, basements, or storage buildings.)
This semester, students in my class INF 393C, Introduction to Paper Conservation, are excited to conduct conservation treatment on a group of architectural drawings from the Alexander Architectural Archives here at UT. The drawings come from the Roy Thomas collection. Thomas was an architect who practiced in Austin and Central Texas from the 1920s through the 1950s. He designed many building types, including homes, schools, churches, commercial buildings, apartments, and service stations. Among other notable projects, Thomas was a lead architect on the Stephen F. Austin Hotel at 701 Congress Ave., the first high-rise hotel in Austin.
Students in my class will conduct surface cleaning, humidification and flattening, and mending on rolled blueprints and drawings on tracing paper. They’ll also have plenty of opportunity to practice and refine their skills on lab teaching materials. By the end of the course, they’ll have one portfolio-ready conservation treatment, complete with written and photographic documentation.
We’re so pleased to be able to work with the Alexander Architectural Archives as our library and archives students develop their treatment skills!
During the spring semester of 2021, I’ve had the pleasure of working with a late-19th century photograph of the Ellis County Courthouse, designed by architect James Riely Gordon. The photograph comes from the collections at UT’s Alexander Architectural Archives. Here, I summarize the rationale and outcomes of the conservation treatment.
In Spring 2021, I’m pleased to perform conservation treatment on a late-19th century photograph of the Ellis County Courthouse, designed by James Riely Gordon. This item comes to us from the Alexander Architectural Archives here at UT Austin. The Ellis County Courthouse was a signature achievement in Gordon’s career designing Texas county courthouses. Construction required two million bricks, “160 car loads of Texas granite, 100 car loads of Pecos red sandstone, used in trimming the building, and 14 cars of iron”1.
The Alexander Architectural Archives seeks stabilization for this photograph, which has high use for scholarship, historic preservation, and display. The first step in treatment is detailed examination that will inform decision-making. The item consists of a silver gelatin print mounted to backing board. While the photo is in good condition, the backing board is acidic, with cracks and losses typical of backing boards of this era.
Stay tuned for more on the rationale and techniques that go into this treatment.
