A bstract A modification of the Steger method is described for measuring the stress in a glaze. The test specimen consists of a double‐pronged fork glazed on the outside so that the distance between the ends of the prongs gives a measure of the glaze stress. A method has been devised to calculate the actual stress in the glaze from the deflection of the prongs. Actual stress curves are given for several body combinations when the specimens are cooled, and the influence of aging and treatment in the autoclave is discussed.
