Hello,
I have recently acquired three calymenes from Morocco, one of them was broken (or composited), and glued. To hide the glue, it was covered with mud, and after removing the glue I discovered an awful white glue.
I tried to dissolve the glue by leaving the fossil in acetone for a whole day, then I left the it in alcohol for another whole day, and nothing happened.
I finally soaked it in hot water but another time nothing happened.
Does anyone know how to remove it?
Thanks!
