Messed up when making Tower Busters.

Hello everyone, I have a question. The other day I made my first batch of tower busters and I have a major problem. I used Styrofoam cups for molds! The Styrofoam ended up melting and then drying onto the towerbusters, and now I can't get it off. My Question: Is there a way that I can take the hardened fiberglass resin apart so that I can recover the quartz crystals? Maybe there is some kind of chemical which will soften the fiberglass resin so that I can recover the crystals in order to use them again? Thanks. Tweet
