Abstract: A glass ceramic is provided that has an upper surface, a lower surface, and a surface zone of at least 10 nm thickness that is substantially amorphous so that a content of crystalline phases in the surface zone is at most 20 vol %. The glass ceramic has at least one lateral pattern with periodic and/or quasi-periodic features with a mean feature spacing of not more than 200 μm. The features are defined by depressions in the material of the surface zone so that the pattern as a whole does not protrude beyond the surface level. The features have a depth that is smaller than a thickness of the surface zone and do not extend into the region of the glass ceramic that has a higher content of crystalline phases.
