  • Tempered glass substrate having reduced iridescence
    Patent number: 11186514
    Abstract: A process for the manufacture of a heat strengthened glass substrate, includes the application of a temporary layer including a polymer on a glass substrate including a glass sheet, then the application to the glass substrate coated with the temporary layer of a treatment for the heat strengthening of the glass including heating, leading to the removal of the temporary layer, and then cooling by blowing of air through nozzles. The glass substrate thus obtained exhibits a reduced level of iridescences.
    Type: Grant

    Date of Patent: November 30, 2021
    Assignee: SAINT-GOBAIN GLASS FRANCE
    Inventors: Guillaume Kaminski, François Guiraud, Romain Decourcelle
  • THERMALLY HARDENED ISOTROPIC GLASS
    Publication number: 20210032152
    Abstract: A process for manufacturing a heat strengthened glass, includes a heat treatment applied to a thermally tempered glass. Moreover, a heat strengthened glass sheet in accordance with standard EN1863-1:2011 has a surface stress of greater than 30 MPa, an edge compressive stress of greater than 30 MPa, a mean optical retardation of less than 40 nm.
