A bstract The stresses developed by five glazes in the field of cone 9 porcelain glazes were determined by the tuning fork method of Blakely. A reaction between the body and glaze at the interface causes a development of stress above the softening point of the glaze. The mat glaze studied showed no crazing even though it was extremely high in tension, whereas a semimat and clear glaze, lower in tension, showed craze marks.
