It looks sort of like styrofoam balls, but it is not. It is also not vermiculite. This is obviously used for satake glass, but I was told you can anneal regular 104 glass in it as well and it will anneal properly the same as if in a kiln? It retains heat a lot better than a fiber blanket or vermiculite.
My electric bill skyrockets to about 400 in the summer and I want to save some money and batch anneal. If I used this medium to anneal, would I have to anneal it later on in a kiln, or would it be just as stong as if I had annealed it directly from the kiln? Boy this would definitely save me money AND time. My kiln takes awhile to heat up.
My question....I want to buy some. Where do I find this miracle annealing medium? I'd love to find out where to purchase it and also some feedback from any members who have used it themselves and their opinion of it.

I asked Akihiro about his comment on "annealing 104 glass in this "annealing bubbles." What he meant was that "you can safely cool 104 glass in this." The Japanese word for "annealing" actually means "gradual cooling" so there's a difference there. "Annealing Bubbles" may prevent thermal cracks in the cooling process but they don't anneal beads.
But it is true that most Japanese beads are not annealed in a kiln.
