Book Restoration: Moisture Content

Recovered Books: Checking Moisture Content in Paper

At each critical stage of the recovery process, we carefully test for any excess moisture content. In cases of particularly thick or heavy books, additional drying may be required to insure that all destructive moisture is removed.

Removing Moisture from Vacuum Freeze Dried Books

Moisture content after freeze-drying is a critical aspect of wet book recovery and restoration. For example, early work done by Document Reprocessors at the Los Angeles Public Library disaster involving vellum-bound volumes and a modified vacuum freeze-drying chamber demonstrated considerable success in drying the items. However, the distortion issue with leather and vellum was not totally resolved at that time. Our new cryogenic drying process, dubbed "Cryo-Drying," employs a large temperature differential between a collector plate and the book in order to considerably slow down the rate of water loss from the text block and the binding material. Thus, careful monitoring of moisture content is crucial to a successful recovery.

Quality Control Insures Successful Restoration
