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: 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: Laminated glass articles and methods for making the same are disclosed. In one embodiment, a laminated glass article may include a glass core layer and at least one glass cladding layer fused to the glass core layer. The at least one glass cladding layer may be phase separated into a first phase and at least one second phase having different compositions. The first phase of the at least one glass cladding layer may have an interconnected matrix. The at least one second phase of the at least one glass cladding layer may be dispersed throughout the interconnected matrix of the first phase of the at least one glass cladding layer. In some embodiments, the at least one second phase may be selectively removed from the interconnected matrix leaving a porous, interconnected matrix of the first phase.

Abstract: Glass compositions that may be used to produce chemically strengthened glass sheets by ion exchange. The glass compositions are chosen to promote simultaneously high compressive stress and deep depth of layer or, alternatively, to reduce the time needed to ion exchange the glass to produce a predetermined compressive stress and depth of layer.

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.
