Heat Strengthened Glass
Heat strengthened glass is a semi tempered glass which has been strengthened thermally by inducing a surface compression of 6000 to 9000 psi as compared to a range of 11000 to 20000 psi in case of fully tempered glass.
In heat strengthening process electrically heated horizontal furnace, which heats the glass to a uniform temperature of approximately 660° C. Ceramic rolls convey the glass through these furnaces at speeds regulated to ensure temperature uniformity and minimal optical distortions.
