***DO NOT ATTEMPT UNLESS SAFETY PRECAUTIONS ARE TAKEN!!**** Since the Hobby Lobby bags of new cylinder beads, I've found myself wanting to start torching random beads. Are they or aren't they glass?? I've lost more beads to the cats jumping on top of my trays and sending them flying so burning one here or there is just fine with me. I haven't gotten to test as many as I'd like just yet bc I'm having technical difficulties with my torch. But so far I'm happy with my findings.
