Janel - shards! Another good one. I even have the hollow mandrels. I have heard of annealing bubbles. I'll try the vermiculite with boro and see how that works. BTW - love your pic! Is it new?  |
Nope, 104. I've made several 104 marbles and cooled them in vermiculite, also venetian style icicles. The trick is DON"T PEAK, until they are dead cold. I use a non contact infrared thermometer if I'm not sure they are cold. When making venetian icicles you need to know what you can reheat and what you can't. Basically if it's thick and round once it is cool leave it alone. If you are going to come back to it leave a stem you can attach to.
