The Tintype was invented by a professor @ Kenyon College in the US in
1856 and was a sheet of iron covered w/a black varnish and then
collodion. They are one-opf-a-kind and if not kept in a dry place will
ultimately (if the surface of the varnish is scrathed or broken) start to
"rust" or, as Risa says, oxidize. It must be kept dry ... other than
that, I'd surely give a call to the Geo. Eastman House in Rochester and
check out what they advise.
