Vivak exhibition cradles

September 8th, 2014

Soon, Spencer Library will unveil its latest exhibition, on the work of John Gould and his atelier. Conservation Services staff support exhibition design by helping the curators present the items in their best light. For bound volumes this work often involves the construction of a supportive cradle.

Many library conservation labs construct cradles and supports from Vivak, a transparent, cold-bendable, PETG plastic. Unlike the more traditional Plexiglas, Vivak can be cut on our board shear (no scoring required).

Once the sheet is cut, the locations for bending are transferred from a paper template to the Vivak sheet. Vivak comes with a protective plastic film that is left in place until the final installation to prevent scratching of the soft plastic.

The plastic can be bent by hand, but we use a sheet metal bender to make the process easier. Plexiglas requires heat to bend, so we are happy to avoid that step and the accompanying fumes that result. Making cradles with Vivak is much quicker and less toxic.

Vivak is not as sturdy as the Plexiglas we used to use, but if stored properly cradles can be reused for multiple exhibits.

Throwback Thursday: Kick Off Edition

September 4th, 2014

Each week we’ll be posting a photograph from University Archives that shows a scene from KU’s past. We’ve also scanned more than 1,700 images from KU’s University Archives and made them available online; be sure to check them out!

This week, we celebrate the start of the 2014 football season on Saturday with this image of the old scoreboard at Memorial Stadium. You can learn more about the history of this building at the KU Places Directory and the KU History website.
