Hello all. Crazing can be a confusing glaze problem, and there are a lot of myths out there regarding its causes. (Just like a lot of glaze defects) I can explain it, but if you want the experts, you can't do any better than the Ceramics Materials Workshop. Here, they provide a short lesson on crazing, its causes, the myths surrounding it, and the chemistry that causes it... yes, always. It's very short; just over 12 minutes. It's also free, so please watch: https://youtu.be/NkNda1R-xro?si=iV-AMlQBlMQWRlPf
