I live in southwest Florida and have about 4 gallon bags of coral that I've picked up on the beach and I've been trying to find an a project to use it in. I thought making some jewelry out of it would be fun, but I wanted to know if anyone on here has ever tried firing coral before? Let alone glazing it. I know thin shells tend to crumble and turn to dust in a kiln, but this beach coral feels a lot tougher than your average shell. Anybody have any thoughts on this?
