Can A Ceramic Cup Be Heated in The Microwave？

The ceramic cup can be put in the microwave oven. The high temperature will not harm the ceramic cup. Even if the ceramic cup is put in the microwave oven, there will be no deformation, fracture and other problems. Common ceramic cups are made of kaolin, clay and porcelain. In the process of production, they need to be fired at high temperature. Even low-temperature ceramic cups are fired at about 700-900 degrees, so the ceramic cups can withstand the temperature of microwave oven.

Two things stand out

1. Frozen ceramics can not be immediately put into the microwave oven. Experienced people know that if the ceramic, pottery immediately taken out of the refrigerator into the microwave is likely to burst.

2. Some ceramics made of kaolin doped with metal impurities are not suitable for microwave ovens. If they are put into microwave ovens, they may produce toxicity and cannot be used.
