Little progress has been made in the past to prevent crazing on porous ceramic ware because many of the fundamental causes of this defect were not known. Three sources of crazing are described which have not generally been recognized as causes of this defect. It was found that a type of crazing may be caused by firing ware under a reducing kiln atmosphere. This defect may also be caused by small changes in volume of the body produced by frost action. A special type of crazing may be caused by mechanical pressure on the ware during service. The defects can be prevented by more careful manufacture and selection of raw materials.
