  • Patent number: 11795102
    Abstract: A coated glass article and of a system and method for forming a coated glass article are provided. The process includes applying a first coating precursor material to the first surface of the glass article and supporting the glass article via a gas bearing. The process includes heating the glass article and the coating precursor material to above a glass transition temperature of the glass article while the glass article is supported by the gas bearing such that during heating, a property of the first coating precursor material changes forming a coating layer on the first surface of the glass article from the first precursor material. The high temperature and/or non-contact coating formation may form a coating layer with one or more new physical properties, such as a deep diffusion layer within the glass, and may form highly consistent coatings on multiple sides of the glass.

  • Publication number: 20230312395
    Abstract: The disclosure relates to glass compositions with high coefficients of thermal expansion and low fracture toughness designed for thermal tempering. These glasses are ideally suited to produce a “dicing” pattern when thermally tempered, even when thin (<3 mm). Disclosed glasses have high thermal expansions at low and high temperatures to produce increased temper stresses once quenched, coupled with low fracture toughness which promotes crack bifurcation and enhanced frangibility. Methods of making such glasses are also provided.

  • Patent number: 11773006
    Abstract: A method of making a glass includes batching constituents, including silica, alumina, boria, magnesia, quicklime, and strontia, where one or more of the constituents is from “dirty” raw material that includes a relatively large amount of sulfur. The method further includes melting and mixing the batch to make glass having sulfur content but free of blisters, suitable for high performance displays.

  • Publication number: 20230295038
    Abstract: A laminated glass article comprises a core layer comprising a core glass composition, and a cladding layer directly adjacent to the core layer and comprising a clad glass composition. A stress of the cladding layer increases with increasing distance from an outer surface of the cladding layer from a compressive stress to a tensile stress, transitions to a compressive stress as a step-change at an interface region between the core layer and the cladding layer, and increases with increasing distance from the interface region to a center of the core layer from the compressive stress to a tensile stress.
