Annealing - stabilizing by adding heat and ramping down slowly. Shocky - glass that pops off in the flame, and usually lands on your neck or lap! Glass - what I use to make my beads.
Lampworkers all know what I mean when I say shocky glass - it's glass that no matter how slowly you introduce it into the flame, it pops off in shards and lands all over you and your workspace. It's usually odd-lot glass (small batches of glass usually produced by mixing several colors of glass together). Did you know you can anneal your glass to make it less shocky?
1. Clean your glass rods first - get the rubber band schmutz off before you put the rods in the kiln. That way, you won't get the burning rubber smell (lol) and the black marks on your glass (which burn off in the flame when you use the rod, but, you know, who wants to take that chance...)
2. If you keep the labels on your glass rods, make sure you anneal like the photo above, with the paper labels outside of the kiln-proper area. Again, this avoids the burning smell of paper and the mess of burnt paper on your rod.
3. Do NOT put the glass in the kiln on top of the rod rests. Ask me how I know. Below you can see two photos of glass that got a nice little bend in them, because I rested them on the rod rest instead of flat on the floor of the kiln!
While this may not stop all your odd-lot glass from shocking, it should help a bit! It's no fun to get burned by glass, so still be careful when introducing your glass to the flame, even if you did anneal it!
