Someone (a "Dr. Doom," as I recall) asked about old Th and U salts.  We have
several solid thorium nitrate samples, in ground glass topped vials, with
lick and stick labes marked in cursive.  I expect they are from the fifties,
if not before.

I'm not offering them for sale, but I wonder what the aforementioned Dr.
Doom wanted with them....
