  • Patent number: 11319235
    Abstract: In a process for manufacturing glass, a mixture of solid glass-forming materials may be melted by application of heat from one or more submerged combustion burners to produce a volume of unrefined molten glass comprising, by volume, 20% to 40% gas bubbles. A refining agent may be introduced into the unrefined molten glass to promote gas bubble removal from the molten glass. The unrefined molten glass including the refining agent may be heated at a temperature in the range of 1200° C. to 1500° C. to produce a volume of refined molten glass. The refined molten glass may comprise, by volume, fewer gas bubbles than the unrefined molten glass. A colorant material may be introduced into the refined molten glass to produce a volume of molten glass having a final desired color.
    Type: Grant

    Date of Patent: May 3, 2022
    Assignee: Owens-Brockway Glass Container Inc.
    Inventors: Zhongming Wang, Udaya Vempati, Casey Townsend, Earnest R Iddings, Sutapa Bhaduri, Nicholas A. Schoenrock, Ya-Cheng Lin

  • Patent number: 10590025
    Abstract: A glass precursor gel and a method of making a glass product from the glass precursor gel are disclosed. The glass precursor gel includes a bulk amorphous oxide-based matrix that is homogeneously chemically mixed and includes 30 mol % to 90 wt. % silica and at least one of the following: (A) 0.1 mol % to 25 mol % of one or more alkali oxides in sum total, (B) 0.1 mol % to 25 mol % of one or more alkaline earth oxides in sum total, (C) 1 mol % to 20 mol % boric oxide, (D) 5 mol % to 80 mol % lead oxide, or (E) 0.1 mol % to 10 mol % aluminum oxide. A method of making a glass product from the glass precursor gel involves obtaining the glass precursor gel, melting the glass precursor gel into molten glass, and forming the molten glass into a glass product.

  • Patent number: 9856163
    Abstract: A nanocomposite material that can withstand prolonged contact with molten glass and glass precursor melts may include a cermet substrate and a glass reaction material overlying the cermet substrate. The cermet substrate may include a refractory metal matrix and ceramic particles embedded in the refractory metal matrix, and the glass reaction material may be the reaction product of molten glass and the cermet substrate in an inert environment. The nanocomposite material can be used to construct any kind of structure, such as an impeller or a vessel liner, that may be exposed to molten glass or glass precursor melts.
