  • Glass segments including identification marking
    Patent number: 8057884
    Abstract: A glass pane is provided. A marking field that includes an uneven surface structure is located on a limited area of a smooth side surface of the glass pane. The limited area is smaller than a total area of the side surface of the glass pane, and the uneven surface structure is more rough than portions of the side surface of the glass pane that are outside of the limited area of the side surface of the glass pane. A marking layer is located on the marking field so as to create an intimate adhesive bond between the marking layer and the marking field. The marking layer includes a color containing a thermochromic pigment that visually indicates that a heat treatment has been carried out on the glass pane by being irreversibly modified at a temperature at which the heat treatment is conducted.
    Type: Grant
    Filed: September 16, 2009
    Date of Patent: November 15, 2011
    Assignee: Saint-Gobain Glass France
    Inventors: Hubert Hauser, Herbert Stadelmann, Andreas Kasper

  • Marking heat-treated substrates
    Patent number: 7615253
    Abstract: A method for visual marking of heat-treated substrates, in particular tempered glass panes. The method modifies a marking layer deposited on a surface of the substrate, that visually indicates that the heat treatment has been carried out, and produces a rough marking field on the surface of the substrate that the marking layer deposited on the substrate exhibits intimate adhesive bonding thereto, which marking layer cannot be completely removed using a mechanical mechanism.
