Stress distribution in severely quenched thick plate glasses was examined. Three kinds of glasses (thermal expansion coefficient: 37-94×10-7/°C) were quenched by air blast from softening ranges of temperature. Photoelastic observations indicated that: 1) Stress distribution in the direction of thickness was not parabolic; stresses and stress gradients were extremely high near the blasted surfaces, 2) Stress distribution was not simple; in some blasting conditions tension at surface layers and saw-teeth-shaped stress distribution were found; 3) The glass with relatively low thermal expantion (60×10-7/°C) could be stressed as effectively as a soft lead glass; glass transition temperature multiplied by expansion coefficient seemed to be a measure of possible stressing.<br>Thus we have found non-parabolic stress distribution which had been forecast theoretically but not found experimentally. The results indicate that stress distribution depends on both the degree of air quenching and the deformation of glass plate during blasting.
