[Nhcoll-l] vivianite preservation

[Becky Desjardins]

Hello all;

One of our curators recently collected a sample of  waterlogged wood (could
be clay) with crystals of vivianite on it. Vivianite changes color when
exposed to air (which is already happening) and the wood/clay is drying
out. Does anyone have any tips for how to preserve it? Keep it in
glycerine? Or oil? I welcome your suggestions.



Met vriendelijke groeten,

Due to the construction of new public museum facilities, depots, labs and
offices, the zoological, geological and paleontological collections of
Naturalis Biodiversity Center in Leiden will be closed to all visitors,
including Synthesys Access applicants, as well as for all loan requests for
two months during March and April 2016, and for a period of about two
years from
August 2016 till summer 2018. The botany collections, housed elsewhere in
Leiden, will remain open to visitors and available for loans until further
announcement. In case of logistic questions and updates on planning and
progress, please check www.naturalis.nl or contact collectie at naturalis.nl. We
apologize for this inconvenience.
