What temperature does ceramic crack?
Dunting is a special type of crack which occurs from stresses caused during firing and cooling. These stresses primarily occur during two critical points of firing called silica inversions which occur at 1063 degrees F (573 degrees C), and 439 degrees F (226 degrees C).
Can a microwave crack a plate?
Cookware Breaking: If a microwave safe dish breaks during normal use in a microwave the problem is most likely a “hairline crack” invisible to the eye, or a chip or visible crack. Liquid can seep into the damaged area and attract microwaves. The resulting heat and steam can create enough pressure to shatter the dish.
