A composite includes a component and a glass or glass ceramic material. The component has a first coefficient of expansion α1 and the glass or the glass ceramic material has a second coefficient of expansion α2. The glass or the glass ceramic material has a surface with a thickness and thickness differences (TTV) within the surface, and thickness fluctuations (LTV). The composite has a residual stress in the glass or the glass ceramic material (WARP), and a geometric and material-physical degree of compatibility KG≥4.
