My email has been acting up and I'm not sure if a previous message went
through.
I need to hear from ceramics experts out there. Does anyone know why
glaze runs off bisque fired pottery? My students glazed some pieces
using various Amaco glazes and all of the colors ran terribly. Did I
fire them too hot, not hot enough, or what? I've never had this happen
before, but I'm using a new kiln and I'm not sure what went wrong.
