Abstract
A method of scoring and/or separating a brittle material is described comprising heating a surface of the brittle material along a predetermined path with a laser, then quenching the heated surface with a stream of cooling liquid, such as water, formed by a nozzle. The portion of the cooling stream impinging on the surface of the brittle material is a substantially columnar flow.
