A component of glass or glass ceramic having predamages arranged along at least one predetermined dividing line is provided. The dividing line has a row of predamages lying one behind the other. The predamages pass continuously through the glass or the glass ceramic with at least 90% of the predamages being cylindrically symmetrical. The glass or the glass ceramic has a material compaction of at least 1% relative to an actual material density in a radius of 3 μm about a longitudinal axis of respective pre-damaged points. The relative weight loss per pre-damaged point is less than 10% and the component has a thickness of at least 3.5 mm.
