  • Publication number: 20220356110
    Abstract: A glass article including at least about 40 mol % SiO2 and, optionally, a colorant imparting a preselected color is disclosed. In general, the glass includes, in mol %, from about 40-70 SiO2, 0-25 Al2O3, 0-10 B2O3; 5-35 Na2O, 0-2.5 K2O, 0-8.5 MgO, 0-2 ZnO, 0-10% P2O5 and 0-1.5 CaO. As a result of ion exchange, the glass includes a compressive stress (?s) at at least one surface and, optionally, a color. In one method, communicating a colored glass with an ion exchange bath imparts ?s while in another; communicating imparts ?s and a preselected color. In the former, a colorant is part of the glass batch while in the latter; it is part of the bath. In each, the colorant includes one or more metal containing dopants formulated to impart to a preselected color. Examples of one or more metal containing dopants include one or more transition and/or rare earth metals.

  • Publication number: 20220339906
    Abstract: A glass article includes a glass core layer and a glass cladding layer adjacent to the core layer. A coefficient of thermal expansion (CTE) of the core layer is greater than a CTE of the cladding layer. The core layer has a tensile stress, and the cladding layer has a compressive stress. A retained strength of the glass article is a strength determined after abrasion of an outer surface of the glass article with 1 mL of 90 grit SiC particles for 5 seconds at an abrasion pressure, and a ratio of the retained strength at an abrasion pressure of 25 psi to the retained strength at an abrasion pressure of 5 psi is at least about 0.3.

  • Publication number: 20220063241
    Abstract: Textured glass laminates are described along with methods of making textured glass laminates. The textured glass laminates may be formed via addition of nanoparticles or manipulation of the glass surface. Laminate compositions are designed to take advantage of glass clad and core properties at Tg, annealing point, strain point, and or softening point, along with glass clad and core viscosities. The resulting compositions are useful for anti-reflection surfaces, anti-fingerprint surfaces, anti-fogging surfaces, adhesion-promoting surfaces, friction-reducing surfaces, and the like.

    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.
