When you’re done working a glass bead in the torch, you can’t just drop it in a cooling blanket.
You need to cool it slowly so it doesn’t cool too quickly.
If the bead cools too quickly, it’ll break as it cools or weaken it so it will eventually break from stress fractures.
You need to cool it gradually to relieve those stresses.
That is why we must anneal it in the kiln.
It’s kinda like life, really. Taking time to cool down properly.
Now put down that knife and get off the ledge slowly, please. You’re making a scene.
