What is Calcining? (with pictures)

M. Haskins Calcining may be performed to change the chemical and physical properties of ore. 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.

Calcined Kaolin - Digitalfire

Calcined kaolin has an important use in ceramic glazes. Al 2 O 3 is essential to the chemistry of the vast majority of glazes and its most readily-meltable natural supplier is feldspars, however they most often oversupply KNaO in providing the needed Al 2 O 3. Raw kaolin is an ideal second, or even primary source of Al 2 O 3.

However, the same clay, when calcined, shrinks less during the process of drying. In the case of glazes, drying shrinkage can become problematic as the clay content of the glaze rises above 10% of the recipe. If a glaze contains so much clay that it shrinks too much as it air dries, it will crack and may even fall off the ware.
