These ceramics include stoneware, porcelain, bone china, and vitreous cookware. In summary, most high fired ceramics are suitable for microwave oven use.
Does clay explode in the microwave?
Water absorbs microwave radiation so it heats up in the microwave. If a ceramic dish is porous, it slowly absorbs liquids and traps them in little cavities in the clay. This not only causes the clay to heat up but the pressuriz ed pockets of water could cause the dish crack or explode.
Why did my plate explode in the microwave?

Are ceramic microwaves better?
As steel is a good conductor of heat, the stainless steel cavity facilitates better heating process and protection against leakage of microwave waves. Whereas, a ceramic cavity has a non-sticky surface i.e. it’s easy to clean and maintain, but the heating process is comparatively longer than stainless steel cavity.
