1. A sheet-like glass or glass ceramic element for anchoring components, comprising
two opposite faces spaced apart by a thickness of more than 2 mm;
an edge surface connecting the two faces that is defined between a first edge of one of the two faces and a second edge of the other of the two faces; and
adjacently aligned filamentary damages that form indentations in the edge surface,
wherein the filamentary damages have a continuous longitudinal extension in a direction from the first edge to the second edge,
wherein the first and second edges define a transition between the edge surface and the two faces,
wherein the edge surface is inclined relative to the two faces and has a direction of inclination relative to the two faces that is consistent along one of the first and second edges, and
wherein the filamentary damages have a length along the longitudinal extension of at least 200 micrometers and form indentations in the edge surface at a depth of less than 20 μm.
