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: Methods for machining glass structures may be performed on fusion-drawn glass laminates having a core layer interposed between a first cladding layer and a second cladding layer. The core layer may be formed from a core glass composition having a core photosensitivity, the first cladding layer may be formed from a glass composition having a photosensitivity different from the core photosensitivity, and the second cladding layer may be formed from a glass composition having a photosensitivity different from the core photosensitivity. At least one of the core layer, the first cladding layer, and the second cladding layer is a photomachinable layer. The methods may include exposing a selected region of a photomachinable layer in the fusion-drawn laminate to ultraviolet radiation; heating the glass structure until the selected region crystallizes; and removing the crystallized material selectively from the photomachinable layer.

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.
