Abstract: A laminate glass article is provided that includes: a core glass layer comprising a first coefficient of thermal expansion (CTE); and a plurality of clad glass layers, each comprising a first primary surface, a second primary surface in contact with the core glass layer and a second CTE that is lower than the first CTE of the core glass layer. The difference in the first and second CTE is about 10×10−7/#C to about 70×10−7/#C. Further, each of the core glass layer and the clad glass layers comprises a viscosity from 109.0 to 1014.0 Poise from about 550#C to about 700#C.

Abstract: Embodiments of glass articles comprising an anneal point (° C.) and a softening point (° C.), and the relationship of (anneal point+softening point)/2 in a range from about 625° C. to about 725° C. are disclosed. In one or more embodiments, the glass articles include a glass composition including SiO2 in an amount in a range from about 63 mol % to about 75 mol %; Al2O3 in an amount in a range from about 7 mol % to about 13 mol %; R2O in an amount from about 13 mol % to about 24 mol %; P2O5 in an amount in a range from about 0 mol % to about 3 mol %, and one or both of MgO and ZnO. Laminates including such glass articles, and methods for making such laminates are also disclosed.

Abstract: A glass laminate for an architectural element has a glass substrate coupled to the architectural element and defines a primary surface facing away from the architectural element. A phase-separable glass cladding is coupled to the primary surface. The cladding has an interconnected matrix with a first phase composition and a second phase that has a second phase composition different than the first phase composition. The second phase is distributed throughout the interconnected matrix. A copper phase is distributed within the interconnected matrix. The glass cladding has an antimicrobial log kill rate greater than about 4 as measured by an EPA Copper Test Protocol.

Abstract: Optical techniques for determining thermal properties of materials are described. Optical techniques include Raman scattering and thermal properties include relative length change and coefficient of thermal expansion. Correlations of features of bands observed in the Raman spectra of several glasses with thermal properties of the glasses are demonstrated. The technique provides a convenient method for determining thermal expansion properties of materials.
