Help!!! Exploding Clay!
I have a problem. A bunch of my students created coil pots, and the bases of them (no more then 1/2 in thick) seem to be "blowing out" in the bisqueware stage of firing. We are using low-fire cone 06 Stoneware and Earthenware clays, with an electric kiln. The pots are completly dryed out when fired, and this has even occurred in my OWN coil pot example I created for the kids. Anyone have any suggestions or help, please respond ASAP! Thanks!
