WebIn thermal tempering, the outside of a glass is cooled faster than the inside. This results in an expanded outer layer and condensed inner layer, which interact to create a strong, compressive surface. In molten glass, this can happen simply by cooling rapidly– the outside will naturally cool faster than the inside. Remember how glass is amorphous?
