Abstract: An element of an inorganic brittle material having two opposed sides and a circumferential edge includes at least three sections. The at least three sections include a first section and two second sections, the second sections adjoining the first section so that the first section is arranged between the second sections. The first section includes an arrangement of openings forming passages from one side to an opposed side of the element so that the first section has a higher flexibility than the second sections.

Abstract: A toughenable glass article includes a glass and has a thickness of less than 100 μm and a cooling state which is such that, after chemical toughening to a depth of 30% of the thickness, the glass article has a relative thermal length change potential in a range from −1500 ppm to ≤0 ppm.

Abstract: A plate-like glass element includes a pair of opposite side faces and an opening having a transverse dimension of at least 200 μm. The opening is delimited by an edge. The edge has a plurality of rounded, substantially hemispherical depressions that adjoin one another. The plurality of rounded, substantially hemispherical depressions having abutting concave roundings which form ridges.

Abstract: A method for producing structured glass articles is provided by removing glass material from a glass element. The method includes the step of etching the glass element to remove the glass material from using an etching medium. The etching medium has a basic aqueous etching solution with a pH of more than 12 and a complexing agent. The complexing agent complexes a leached constituent of the glass element.
