All clay bodies contain some measure of carbon, organic materials, and sulfur. These burn off between 572 F and 1470 F (300 C and 800 C). If for some reason—such as poor ventilation within the kiln—these are not able to burn out of the clay body, carbon coring will occur. This will considerably weaken the clay .
