Abstract
A method for processing glass elements is provided. The method includes introducing a perforation line for parting a glass element introduced into the glass element during or after a hot processing process at an elevated temperature of at least 100° C. Spaced-apart filamentary flaws are introduced into the glass element along the predetermined course of the perforation line by a pulsed laser beam of an ultrashort pulse laser, and, during or after the introduction of the filamentary flaws, the glass element is cooled down so as to produce a temperature gradient, which induces a mechanical stress at the filamentary flaws, whereby the breaking force required for parting the glass element along the perforation line is reduced.
