  • Patent number: 11023630
    Abstract: A method of making a glass article includes melting batch materials to produce molten glass, heating or cooling the molten glass to a temperature, forming a glass article from the molten glass. The batch materials include a plurality of viscosity-affecting components that become at least part of the glass article. Selection of the batch materials or the temperature was made at least in part using computer-implemented modeling where predicted equilibrium viscosity of the glass at the temperature is a function comprising concentrations of viscosity-affecting components and temperature-independent fitting coefficients for the viscosity-affecting components.

  • Publication number: 20210087103
    Abstract: According to one embodiment, a glass article may include a glass body having a first surface and a second surface opposite the first surface. The first surface of the glass body may be etched to a depth less than or equal to about 25% of the maximum initial flaw depth Ai of a flaw population present in the first surface. The flaw population of the first surface is etched to selectively remove material adjacent to each flaw of the flaw population along the maximum initial flaw depth Ai. When the glass article is under uniaxial compressive loading, at least a portion of the first surface is in tension and a uniaxial compressive strength of the glass article is greater than or equal to 90% of a uniaxial compressive strength of a flaw-free glass article.

  • Patent number: 10899659
    Abstract: According to one embodiment, a glass article may include a glass body having a first surface and a second surface opposite the first surface. The first surface and the second surface each have a radius of curvature. The first surface of the glass body comprises a flaw population extending from the first surface into a thickness of the glass body with a maximum initial flaw depth Ai. The first surface of the glass body may be etched to a depth less than or equal to about 25% of the maximum initial flaw depth Ai of the flaw population present in the first surface. When the glass article is under uniaxial compressive loading, at least a portion of the first surface is in tension and a uniaxial compressive strength of the glass article is greater than or equal to 90% of a uniaxial compressive strength of a flaw-free glass article.
