Hi ... I recently collected some fragile shell fossil specimens
from the Calvert Cliffs area in Maryland. Most of them are
chalky white, and some people have advised me to paint it with
a glue solution (1 part Elmers to 4 parts water).
 
However, I was wondering if anyone could suggest a transparent
hardener? Some of the fossils have a little color, presumably
minerals absorbed from ground water. I'd like to preserve those
colors.
 
Thanks!
