Pierced vellum binding on: Qvinti Horatii Flacci Poemata, Amsterdam, 1662.
This volume was in a full leather binding in poor condition, with one board and the spine missing, and staining and skinning of the leather. The textblock was water-stained throughout. Because the text leaves required aqueous treatment and the binding was so damaged, the volume was rebound.
The binding was discarded and the text block disbound. The leaves were cleaned with a vulcanized rubber sponge as needed. The text leaves were washed in a solution of 70% isopropyl alcohol/30% distilled water, followed by several baths of distilled water conditioned using calcium hydroxide to a pH 8.5.
