Abstract

The invention relates to a glass material having a hardened surface layer in which modified material stresses are produced in order to increase the mechanical resistance and to form a breaking pattern. To this end, the resistance in the surface layer is higher than the resistance in a core layer. The inventive glass is characterised in that the material stresses are produced by locally exposing the glass surface to a laser beam in a controlled manner, at predetermined positions, in order to form a predetermined breaking pattern. Furthermore, the invention relates to a method for hardening glass, according to which the temperature of the glass surface is increased in a locally defined manner by exposing said surface to a laser beam (7), until the glass transition temperature is reached, and the locally heated glass surface (8) is then quickly cooled.
