This is an antique dish that was originally used for some purpose in a medical or experiment Laboratory.
These are New Old Stock!
It is 1 1/2" by 1 1/2" by 5/8" tall.
It is solid clear glass.
One side has been ground so that it is opaque, presumably so that someone could charcoal or pencil what was in the dish. It is not exactly a petri dish because it has no lid. It may have been used for powdered chemicals or salts just prior to mixing.
We find that these make great ring dishes or also for use as open salts.
We have only ONE left.
