Abstract

Methods for cutting a fragile material are provided. The methods comprise the step of heating the fragile material along a separation path to separate the fragile material into a first portion and a second portion. At least the first portion includes a first thermal affected zone extending along the separation path. The methods further include the steps of spontaneously splitting at least part of the first thermal affected zone from the remainder of the first portion along a first split path extending a first distance from the separation path. The spontaneous splitting occurs as a consequence of the step of heating the fragile material.
