  1. Hi everyone, Hobbyist ceramist with a few years of experience here, but not so much glaze chemistry knowledge. I make work at a studio in Germany since a few years and since the summer, we noticed a lot of new issues with various glazes used at the studio. Nothing seems to have changed a priory with the way we do things. We fire with 2 different Rhode ecotop kilns at 1220 celcius. All ours work is made using a white stoneware clay from one distributor. We order commercial glazes from the same distributor and a few other glazes from another one. We've been using the same glazes for yea
  2. Wanted to ask you guys about your experience with this defect we've been having. It's not glaze specific and I highly doubt these growths are just bubbling up from the clay during a glaze firing (but maybe). This defect does not occur only on mugs that are close to the thermocouple, but I don't want to rule out the possibility that it is thermocouple related. Ring any bells?
