A component includes a glass or glass ceramic having a thickness and a plurality of predamages. Each predamage of the plurality of predamages has a longitudinal axis and passes continuously through the thickness of the glass or the glass ceramic. The component also includes a material compaction of the glass or glass ceramic that is at least 1% relative to an actual material density in a radius of 3 μm about the longitudinal axis of each predamage so that the glass or the glass ceramic has a relative weight loss per predamage that is less than 10%.

Components made of glass or glass ceramic having predamage along predetermined dividing lines

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.
