This invention relates to a non-contact thermal-score, mechanical snap method and apparatus for reliably cutting glass yielding pieces of glass having a high edge strength. A delineated infrared source is positioned at one focus of an elliptical reflector means, thereby causing its energy to be concentrated at a focus locus that is caused to coincide with one surface of the piece of glass to be cut along an intended line of fracture, creating a thermal score or heat path. The piece of glass is then severed by applying a bending moment around the heat path.
