I've got cake stands drying; these are the ones I made with the quarter trick last week. So far, so good: no cracking or warping [knocks wood.]
And I've got serving baskets, a couple of which morphed into colanders:
Aaaaand, my newest shape: stoneware steamers!
They work (I hope they work!!) Like bamboo steamers: put them on the rim of a cook pot of water, and boil the water. The steam is forced up into the lidded piece, and the vegetables therein cook. Each piece also has an underplate, so the steamer doubles as a serving dish. I got the idea using my bamboo steamer and wishing it looked nicer and didn't have that funny smell.
It seems like it should work: steaming is not like putting a piece right on a burner, and if you put the steamer over the water and then bring it to a boil...well, I'll say again: it seems like it should work. In any case I can't wait to take one of them for a test drive!
