Abstract
Method and device for cracking the glass plates parallel to their faces and in their entirety, characterized by the fact that one or more rupture fronts are displaced, which have as origin one or more rupture initiations previously drawn on the edges, by symmetrically cooling the faces progressively or simultaneously in all their extension, after raising the sheet to a sufficiently high temperature but nevertheless inferior to that which corresponds to the strain-point of the glass.
