Heat is the degree of hotness, which can increase and decrease and is controlled by an energy that causes a rise in temperature, such as gas or electricity. With different products and at different temperatures, it causes expansion, evaporation and other physical changes. In ceramics, it changes clay, a soft, pliable product, into a hard breakable one and colors from powder into a glazed, non absorbent, breakable surface.
