ABSTRACT:
This invention relates to a device for causing fracture of a brittle material such as a glass. The invention employs at least two fluid streams directed against the surface of the material to be cut. One stream is a heated fluid such as air whereas a second flow of colder fluid such as ambient temperature air is also directed against the surface to be fractured at a displaced location. The combined effect of heating and rapid cooling causes thermal stress and fracture to occur in the material to be cut. The manner of applying the fluid according to this invention produces a highly controllable propagating fracture.
