A glass element includes a glass surface including a surface structuring with a structured region of the glass surface that, owing to glass removal, has a higher roughness than an adjoining unstructured region of the glass surface, the structured region having a mechanical stress profile which can be measured by stress birefringence. The structured region has a compressive stress on the glass surface that is higher in absolute terms than a stress in the adjoining unstructured region. At least one of the following is satisfied: the compressive stress becomes smaller in absolute terms with increasing depth and transitions into a tensile stress, a maximum tensile stress being smaller in absolute terms than the compressive stress on the glass surface; or the compressive stress has a value of less than 5 MPa in absolute terms on the glass surface and becomes smaller in absolute terms with increasing depth.
A glass element, comprising:
A method for producing a glass element comprising a glass surface which has a surface structuring with at least one structured region of the glass surface that has a higher roughness than an adjoining unstructured region of the glass surface, the method comprising:
A batch, comprising:
