Subject: Rehydrating invertebrate specimens
The following was originally posted to nhcoll and is reproduced here without the knowledge or consent of the authors I'm an objects conservator at Texas Memorial Museum. One of our curators just asked me about what would be the best way to rehydrate specimens from a collection of cave invertebrates which unfortunately dried out. I understand that these types of specimen are difficult to rehydrate due to the chitinaceous exterior. I have read 2 papers (see below) which recommend using combinations of trisodium phosphate/or other detergents with (deionized) water or "alcohol", heated or perhaps under vacuum, to rehydrate specimens. Can anybody offer any other suggestions/helpful hints? I'm trying to work out what would be the least damaging method to use, accepting that some damage will occur, but that this is acceptable if the specimens regain some scientific value. Of course, all procedures carried out on the specimens will be recorded. I'd be grateful for any help anybody could give, Kathy Hall Conservator Materials Conservation Laboratory Texas Memorial Museum 10100 Burnet Road Austin, Texas 78758 512-471-6090 Fax: 512-471-6092 *** Conservation DistList Instance 11:39 Distributed: Thursday, October 23, 1997 Message Id: cdl-11-39-011 ***Received on Thursday, 23 October, 1997
