Amberina glass

From: Stephen Koob <koobsp>
Date: Wednesday, July 14, 1999
In reply to Mary Harris-Serrao's inquiry about removing marks
(possibly ink) from amberina glass, I would suggest swabbing with a
50/50 mixture of ethanol and water.  Examination under a binocular
microscope should be informative, to determine whether the marks are
on the surface, or scratched into the glass.  If the marks are some
kind of paint, other solvents, such as acetone, naphtha, or xylene
might work.  The surface of amberina glass is quite solid and
stable, and will not be affected by the solvents.
