Abstract: A glass ribbon in the form of a glass roll is provided that is optimized with respect to the requirements of a long service life and at the same time compact dimensions. A bending radius on the inner side of the thin glass roll is determined by performing breakage tests on samples of the glass material, statistical parameters are determined on the basis of the breakage tests, and the statistical parameters are converted into a range of bending radii which meet the requirements on service life and the most compact dimensions possible of the thin glass roll.

Abstract: Chemically toughened glass articles are provided that include a first compressive stress region extending from a first surface, a second compressive stress region extending from a second surface, and a chamfer structure at an edge, which connects the first and second surfaces. The first compressive stress region has a first compressive stress of 100 to 2000 MPa and a first 60% depth (F60D). The second compressive stress region has a second compressive stress of from 100 to 2000 MPa and a second 60% depth (S60D). The chamfered structure has a first ratio of average chamfer height (Havg) to a total chamfer height variation (TCHV) that is at least 250 μm2.

Abstract: An element of an inorganic brittle material is provided having two opposed sides and a circumferential edge. The element has at least three sections that include a first section and two second sections. The second sections adjoin the first section so that the first section is between the second sections. The first section has an arrangement of openings and interconnectors so that the first section has a higher flexibility than the second sections. The arrangement of openings has at least one opening shaped as a fold with two limbs that intersect to form a vertex.

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.
