Abstract: Alkali aluminosilicate glasses that exhibit fast ion exchange performance and having low softening points that enable the glasses to be formed into non-planar, three-dimensional shapes. The glasses contain less than about 1 mol % of boron oxide and, in some embodiments, are substantially free of B2O3. Furthermore, these glasses have excess amounts of alkali oxides relative to both Al2O3 and P2O5, in order to improve melting behavior and ion exchange performance while still achieving sufficiently low softening points to allow for formability.

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 (σs) at at least one surface and, optionally, a color. In one method, communicating a colored glass with an ion exchange bath imparts σs while in another; communicating imparts σs 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.

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: A glass laminate includes a glass core layer having a core coefficient of thermal expansion (CTE) and a glass cladding layer adjacent to the core layer and having a cladding CTE that is less than the core CTE such that the core layer is in tension and the cladding layer is in compression. A stress profile of the glass laminate includes a compressive peak disposed between an outer surface of the cladding layer and an inner surface of the cladding layer.
