I recently purchased a pack of gravel from Florida filled with Miocene and Pleistocene fossils. Among the fossils was a giant beaver molar. I rinsed it off with water, left it to dry and came back to find that has started to peel. Has this happened to anyone before? How would you recommend consolidating the tooth so that it stops peeling? I have tried to use Butvar before but I have never seemed to get the right ratio to protect the fossil while avoiding the shine. Would you recommend dunking the entire tooth in the solution or to apply some using a dropper or paint brush? Any help would be greatly appreciated.
