When scribing and snapping a glass plate, a fluid is applied over the scribe mark prior to snapping in order to substantially reduce the force required to break the glass and to provide a clean fracture. While there are various commercial cutting fluids designed for this purpose, the most commonly-used fluid is kerosene. All of these materials, however, leave contaminating residues on the glass which must be removed after separation.
