Pottery Chalkboard: Thermal Expansion, Glaze Fit, and Common Glaze Issues
Thermal Expansion, Glaze Fit, and Common Glaze Issues
In this video, our clay chemistry expert, Tyler Didier, explains the science behind some of the most common glaze issues: crazing/crackling, shivering, dunting, and chipping. If you've ever wondered about thermal expansion and glaze-body interaction, this is your video!
Our clay expert, Tyler Didier, gives a blackboard talk into the science of what crazing is and why it happens in your pottery work, how serious the problems it causes are, and what to do about it. He talks thermal expansion, clay/body interfacial "zones", fluxes, and more.
