Abstract
A method for cutting a glass article from a strengthened glass substrate having a surface compression layer and a tensile layer includes forming an edge defect in the surface compression layer on a first edge of the strengthened glass substrate. The method further includes propagating a through vent through the surface compression and tensile layers at the edge defect. The through vent precedes a region of separation along a cut line between the glass article and the strengthened glass substrate.
