Crazing is a disaster for a production potter. Consider what one said: "I have just recently been contacted by a customer due to small lines in her bowl.

Could anyone tell me if it is the glaze and if there is anything I can do to alter the recipe?" Yet this is easy to fix.

In ceramics, glaze fit refers to the thermal expansion compatibility between glaze and clay body. When the fit is not good the glaze forms a crack pattern or flakes off on contours.
