Pixie, I'd just dump them all in, but then I'm a bead stacker.
If you're worried about doing that or any other kind of melt down, you could put down a piece of fiber blanket on the floor of your kiln and spread the beads out on it. Alternatively, a layer of kiln wash isn't a bad idea.
Barbara, I garage at 925. When I run the annealing program it goes up to 950 for a soak.
