Dear Paleoneters,
some time ago, I have inherited a large collection of (petrographic)
thin sections, mostly from limestones, prepared to study their
microfossil contents.
A significant number displays a centripetal deterioration (see
pictures attached). Apparently it affects the glue. May be you have
faced a similar problem and I should be very pleased if you could
share your "bad" experience:
1) is there a way to revert the process?
2) if not, is there a way to stop it?
"Bien à vous",
Bruno Granier
