Can you harden polymer clay in the microwave?
Microwave ovens heat the inside of clay just as much as the outside, so as the cooking continues, parts of the mass will begin to superheat, melt, and actually bubble and boil while other parts of the polymer clay mass will merely begin to harden. After a few minutes, the overheated polymer will expand and ooze out.
