Ceramic is a material that is used in many different applications, ranging from cookware to flooring. When it comes to temperature, ceramic is safe up to about 1,200 degrees Fahrenheit. At temperatures above this, the material can start to break down and release harmful chemicals into the air. For most household uses, such as cooking on the stovetop or in the oven, ceramic is more than safe enough. However, if you are using ceramic at very high temperatures, it is important to be aware of its limitations.
