Changes in firing

All clays and many minerals contain water which does not leave the body until above 700°F. Organic (carbon) materials need to be oxidized (burned out). Other minerals, such as calcite, break down and give off a carbon dioxide gas. Minierals such as flint (silica) undergo a sudden expansion on heating to 1060°F and contraction during cooling.
