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:
A method includes forming a glass article. The glass article includes a core and a clad adjacent to the core. The core includes a first glass composition. The clad includes a second glass composition different than the first glass composition. A degradation rate of the second glass composition in a reagent is greater than a degradation rate of the first glass composition in the reagent.
Abstract:
A method of manufacturing a laminated glass article having a first clad layer, a second clad layer, and a core layer between the first clad layer and the second clad layer, by exposing an edge of the core layer. An etchant can be applied to the edge of the laminated glass article to form the recess. The recess can then be filled.

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:
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.
