I’m planning on ordering the Amaco Cosmos Dark Star CO-08. It was a tie between that and the white-based glaze, so the white/clear version will be the October glaze.
I watched the Amaco video for these glazes. Cara is using a collar with drip tray, like we’ve used for the macrocrystalline glazes that @cmcooper0 is doing tomorrow (Sunday 8/18) and the past. However! Cara says that if you leave the normal (1/2-1/4") unglazed foot, you should be okay. (Not sure I believe that, though.)
Those of you who are interested should start thinking about what you’re making. Cara says that these should only go on decorative pieces. While they are technically food safe, the surface is a bit fragile. AND you shouldn’t glaze both surfaces as the Cosmos glazes out-gas and will produce bubbles in the glaze if both surfaces are glazed. You should also make a drip-plate for your piece, just in case. I am planning to have a test piece fired before the glaze class where you will have access to the special glaze, and I’ll put it on a drip-plate to see what happens.
A drip plate varies from a regular cookie in that it has edges so that a really drippy glaze won’t run off onto the kiln shelf.
