Subject: Freeze-drying
I am acting as a consultant for the rescue and recovery of some 5000 plus documents at a site at ground zero, September 11, 2001. The records for these documents are no longer available, the documents were wet and there was a severe mold infestation as well as diesel fuel in the water. Examination could not be done until the site at ground zero was cleared and the structure stabilized. The water line is about 4 feet off the floor. The documents are in file cabinets, on rolling stacks and some are bundled in plastic. The documents by and large are still wet from the 9/11 event until today I am interested in getting information from book and paper conservators who have worked on items that have printed colored inks on the pages of the documents and in the books after they have been freeze-dried. After freeze drying was it possible to easily separate the pages? Could the pages be separated without lifting the ink? Do some inks break down from the freeze-drying process? The interest here is to preserve the information on the document not the documents themselves. I would also like to hear the pros and cons of the freeze-drying process *** Conservation DistList Instance 16:58 Distributed: Thursday, April 3, 2003 Message Id: cdl-16-58-005 ***Received on Thursday, 3 April, 2003
