Today on Verso, book conservator Kristi Westberg describes the process of performing repairs on a copy of a 16th-century astronomy book censored by the Roman Catholic Church. Kristi used something called solvent set tissue to make her repairs, and she made the solvent set tissue in-house. Here’s a peek at the process:
First, Kristi pours an adhesive called Klucel G into a tray.
Next, she uses a brush to pick up some of the adhesive.
She then spreads a thin layer of the adhesive onto a sheet of clear polyester.
Finally, she lays a piece of lightweight Japanese paper on the adhesive.
