Abstract

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%.
