    Abstract: A method of making a glass having antimicrobial properties and high compressive stress. The method includes a first ion exchange step in which potassium cations are exchanged for sodium cations in the base glass to provide a surface layer under compressive stress, followed by a second ion exchange in which silver cations are exchanged for potassium and lithium ions in the glass to produce the antimicrobial glass. In some embodiments, the antimicrobial glass has a maximum compressive stress that is at least 80% of the maximum compressive stress obtained by the potassium-for-sodium exchange in the first bath. A base glass and an ion exchanged glass antimicrobial having antimicrobial properties are also provided.

    Abstract: Computer-implemented methods and apparatus are provided for predicting/estimating (i) a non-equilibrium viscosity for at least one given time point in a given temperature profile for a given glass composition, (ii) at least one temperature profile that will provide a given non-equilibrium viscosity for a given glass composition, or (iii) at least one glass composition that will provide a given non-equilibrium viscosity for a given time point in a given temperature profile. The methods and apparatus can be used to predict/estimate stress relaxation in a glass article during forming as well as compaction, stress relaxation, and/or thermal sag or thermal creep of a glass article when the article is subjected to one or more post-forming thermal treatments.

    Abstract: Borosilicate glasses are disclosed having (in weight %) 66-76% SiO2, 0-8% Al2O3, 10-18% B2O3, 0-4% Li2O, 0-12% Na2O, 0-12% K2O, 1-1.5% Ag, 1.5-2.5% Cl− and 0.01-0.06% of a summed amount of CuO and NiO, wherein the glass composition is bleachable upon exposure to ultraviolet irradiation from a stable state color or shade to a lighter color or shade. Such reverse photochromic borosilicate glass compositions may be thermally darkenable. The borosilicate glasses may be strengthened via ion-exchange strengthening treatment. The borosilicate glasses may retain their reverse photochromic and thermally darkenable properties even after ion-exchange strengthening treatment.

    Abstract: A method of treating a substrate is provided that includes the steps: submersing a substrate having an outer region containing a plurality of divalent exchangeable ions in a bath that comprises a polar solvent and a plurality of divalent ion-exchanging ions, the substrate comprising a glass, glass-ceramic or ceramic; pressurizing the bath to a predetermined pressure substantially above ambient pressure; and heating the bath to a predetermined temperature above ambient temperature. The method also includes a step of treating the substrate for a predetermined ion-exchange duration such that a portion of the plurality of divalent exchangeable ions is exchanged with a portion of the divalent ion-exchanging ions. In addition, the step of treating the substrate results in a greater number of divalent ion-exchanging ions entering the substrate than divalent exchangeable ions exiting the substrate.
