Abstract
Methods of separating a glass web include the step (I) of exposing a path on the glass web to at least one laser beam to produce thermal stress along the path without damaging the glass web. The methods further include the step (II) of creating a defect on the path while the path is under thermal stress produced during step (I), whereupon the glass web spontaneously separates along the path in response to the defect.
