Can anyone tell me if the attack will damage the piece if it is in
fact mammoth ivory (or if it's actually some kind of plastic...)
and if the attack will damage the ink or whatever the colorant is
in the design"
Whether they used the traditional India ink, or acrylic paint,
Attack will almost certainly strip it from the design. The ivory
itself is pretty tough stuff, but some of the things that give the
mammoth ivory it’s colors, might be affected by the solvent.
My gut reflex is attack might not be your friend here…
Heat might be your friend, here.
