  • Publication number: 20200369551
    Abstract: A method for processing glass elements is provided. The method includes introducing a perforation line for parting a glass element introduced into the glass element during or after a hot processing process at an elevated temperature of at least 100° C. Spaced-apart filamentary flaws are introduced into the glass element along the predetermined course of the perforation line by a pulsed laser beam of an ultrashort pulse laser, and, during or after the introduction of the filamentary flaws, the glass element is cooled down so as to produce a temperature gradient, which induces a mechanical stress at the filamentary flaws, whereby the breaking force required for parting the glass element along the perforation line is reduced.

  • Patent number: 10556827
    Abstract: A product is provided that includes a volume-colored monolithic glass or glass ceramic element and to a method for producing same. The glass or glass ceramic element has a first region in which the coloration is modified so that light transmission of the first region differs from light transmission of a second, adjacent region. The light scattering in the region of modified coloration in the glass or glass ceramic remains the same as light scattering in the second, adjacent region with non-modified light transmission.

  • Publication number: 20040129024
    Abstract: The invention relates to a method and a device for reducing the adhesion tendency during the hot forming of a glass body, using at least two moulds, which are positioned on either side of the glass body and are brought into contact with the glass body at a temperature, at which the glass is deformable, whereby the moulds are configured with electrically conductive surfaces. The disadvantage of existing methods and devices is that the moulds have a tendency to adhere to the glass body to be formed and that the surface quality of the glass is impaired. The invention therefore discloses a method, according to which the conductive surfaces of the moulds that come into contact with the glass body are supplied with an alternating current. The device for carrying out said method has electrically conductive mould surfaces, which are connected to an alternating current source. This guarantees that a larger processing window is available as a result of the reduced adhesion tendency, i.e.
