Subject: New address for IPI Polysulfide and film project finished
... Anyway, two things: IPI has now moved. Phone numbers are still the same and my email is the same. New mailing address is Rochester Institute of Technology Image Permanence Institute Frank E. Gannett Memorial Building P.O. Box 9887 Rochester, NY 14623-0887 The second thing I was reminded of (to let people know about) by Ellen McCrady. She called requesting information for the Abbey NL readers. The final report for NEH/NHPRC on the use of Potassium Polysulfide toning for the enhanced permanence of microfilm and the final report for NEH on the stability of safety film are both completed. The polysulfide report contains the development of IPI's polysulfide toner formulation, toning methods, recommended starting point for anyone attempting the toning method (time, temp., etc.), and test methods for quality control. The total volume is about 174 pages long and is public information. Copies are available, although we must charge for copying, binding, shipping and handling. Total cost is $20.00. The safety film project report contains information regarding the relative stability of cellulose ester based films (triacetate, acetate propionate, acetate butyrate, diacetate, nitrate) and polyester. Acetate butyrate film is used in contemporary and historic sheet film by Kodak. Effects of storage temperature and humidity are explored. This volume is about 103 pages long and is also $20.00. Copies of either report can be obtained by writing to IPI at the above address.
