Abstract

A method for the production of glass or glass ceramic elements from flat glass or glass ceramic parts is provided where the edges of the glass or glass ceramic elements are treated by a combination of two processes. The flat glass or glass ceramic element with an edge surface connecting the two side surfaces is produced. The edge surface has at least one first elongated, strip-shaped edge region and at least one second elongated strip-shaped edge region, which are formed by a ground edge. The edge regions extend in the longitudinal direction along the edge surface and along the side surfaces. The first edge region has elongated parallel filamentary damages that are parallel and adjacent to one another and, in particular, spaced apart equidistantly, in the longitudinal direction thereof extending transversely to the side surfaces and along the surface of the first edge region.
