Abstract
The invention provides for placing a material to be scribed in a gaseous atmosphere and contacting the surface of the material with a non-cutting heated tip. The heated tip is rounded to prevent cutting and is moved relative to the material. The tip is heated during the scribing operation, either continuously at a prescribed level, or discontinuously in order to maintain the average temperature at a prescribed level.
