Pyrite Preservation Predicament
I apologize for referring to a pesky invertebrate in the following post,
but I would think that my problem could be addressed by readers who have
experience with either pyritized shells or pyritized bones.
I have a small pyritized ammonite fossil that lost its gold color after
I made an RTV silicone rubber mold of it. It turned dark and dull, much
like tarnished silverware. What (if anything) can I do to restore it to
its original golden color? Is there a recommended sealer for iron
pyrite fossils? Are there any other methods you advocate to protect and
preserve the specimen?
