  • Method of making glass sheets with gas pretreatment of refractory
    Patent number: 10435323
    Abstract: A method of making a glass sheet includes exposing a refractory block material comprising at least one multivalent component to a reducing atmosphere for a time and at a temperature sufficient to substantially reduce the at least one multivalent component of the refractory block material. The method also includes flowing molten glass over the refractory block material that has been exposed to the reducing atmosphere while preventing substantial re-oxidation of the at least one multivalent component.
    Type: Grant
    Filed: January 12, 2015
    Date of Patent: October 8, 2019
    Assignee: Corning Incorporated
    Inventors: Matthew John Dejneka, Benjamin Zain Hanson, Thomas Dale Ketcham, James Robert Rustad, Susan Lee Schiefelbein, Kochuparambil Deenamma Vargheese
  • Method of making glass sheets with vehicle pretreatment of refractory
    Patent number: 10047000
    Abstract: A method of making a glass sheet includes treating a refractory block material comprising at least one multivalent component with a vehicle comprising at least one redox altering component or precursor. The method also includes flowing molten glass over the refractory block material, wherein the treatment of the refractory block material with the vehicle comprising at least one redox altering component or precursor reduces the amount of oxygen production resulting from interaction between the at least one multivalent component and the molten glass.

  • GLASS FORMING APPARATUS AND METHODS OF FORMING A GLASS RIBBON
    Publication number: 20170044041
    Abstract: A glass forming apparatus comprises a forming device configured to form a glass ribbon from a quantity of molten glass. The glass forming apparatus includes a refractory material comprising monazite (REPO4). In another example, a method of forming a glass ribbon with a glass forming apparatus includes the step of supporting a quantity of molten glass with a refractory member comprising a refractory material comprising monazite (REPO4). The method further includes the step of forming the glass ribbon from the quantity of molten glass.
