I garage as I go, but then I make marbles and not beads. I do have vermiculite and when I'm making marble blanks, think pulling points only with 15mm solid rod, I cool the blanks in vermiculite and then batch anneal. I find that the blanks survive better than tossing them in the kiln. There can be a large temperature differential on 4 inches of 15mm rod.
