What is Calcining? (with pictures) - Info Bloom

Calcining, also called calcination, is an industrial process that uses very high temperatures, often between 1,400-1,800 degrees Fahrenheit (800-1,000 degrees Celsius) or higher, to change the physical and chemical properties of various solid materials, such as minerals, metals, and ore. The origin of the term comes from one of the oldest and most common calcining processes: turning limestone, also
