Abstract: A method is provided for scoring glasses. The method includes the steps of generating a deep crack in the glass along an intended separation line by exerting pressure onto the glass surface using a rigid scoring tool, wherein the scoring tool, by being pressed against the glass surface and due to the advancement force while introducing the deep crack generates a zone of elastic strain in the glass in a direction along the glass surface and perpendicular to the separation line, which extends in an arc in the plane defined by the separation line perpendicular to the glass surface such that one leg of the arc is located close to the contact point of the scoring tool on the glass surface and another leg is located inside the glass. The arc being open towards the advancement/advancement direction of the scoring tool.

Abstract: A method and system for assessing the quality of at least one component of optical material which has at least one first center axis includes directing at least one light beam towards at least one detector device such that while changing the position and/or orientation of the component relative to the light beam, the light beam crosses at least from time to time the component and determining, with at least one determination device, at least one characterizing value of at least one figure of merit of the component based on analyzing, with at least one analyzing device, the dependency of a parameter of the light beam detected by the detector device on the position and/or orientation of the component.

Abstract: An improved measurement method and a corresponding measurement device are provided that measure the edge strength of plate-shaped elements made of brittle-fracture material. For this purpose, a long sample is drawn apart at the short edges, wherein the force transmission points lie next to the center of gravity of the base surface of the sample.

Abstract: A method for winding up a glass ribbon is provided, in which, prior to winding up the glass ribbon, the two surfaces of the glass ribbon are each initially treated with a water-containing medium and subsequently dried so as to produce a defined content of water molecules on the two surfaces, by achieving a saturation of the surfaces of the glass ribbon with water, without bringing about an excess of water molecules. A glass roll is produced in which the electrostatic charge of the glass surface is reduced and, as a result, any undesired excess adherence of the glass surface to an interleaf material is prevented and, in this way, glass breakage, in particular during winding up and/or unwinding of the glass roll, can be markedly reduced.

Abstract: A method for producing long-term bendable glass material includes: bending a glass material in a bending radius in a range of 1 mm to 107 mm; storing the bent glass material for a time period of at least 1 day; inspecting at least a portion of the bent glass material for damage after the storing; and classifying the inspected bent glass material as a reject if damage is detected or as a long-term bendable glass material if no damage is detected.

Abstract: A long-term bendable glass material includes a glass material having a bending radius in a range of 1 mm to 107 mm. The glass material is structured such that a number of breaks developing over a course of time after a storage period of at least one day displays a remaining probability of breaking of less than 0.1 for a storage time period of a maximum of half a year.
