ABSTRACT:
A method of and apparatus for cutting relatively thick glass sheets by applying surface contact, conductive heat to the glass surface along the desired line of cut. An elongated, heated conductor rod is placed on the glass surface along the desired line of cut for transmitting heat thereto to create a thermal differential line and effect a cut therealong. Pressure means bear against the conductor rod to maintain the same in continuous contact throughout with the glass surface along the length of the desired line of cut.
