Here are three tables that I made for a client using CA claro Walnut. There are ammonite fossils set in the tops. They are finished w/ BLO then a water based ploy. Your feedback is appreciated.
An interesting and disturbing thing happened when I used silicone caulk. I had to rout out the pockets rather deep, as part of the fossil sits rather wide, and lay them in a thicker bed of caulk. Well, as it cured, it sucked the ammonites down into the pocket. I had to repop them, and lay in a thicker coat. Luckily it worked out!
