Abstract: A glass article is provided that includes: a glass substrate comprising a thickness and a primary surface; and a textured region defined by the primary surface. The textured region comprises a plurality of sub-surface hillocks, each hillock having a top surface and a base, the base located below the primary surface of the substrate. The plurality of hillocks comprises an average lateral feature size from 0.1 μm to 3 μm and an average height from 5 nm to 200 nm. Further, the primary surface of the substrate is substantially planar.

Abstract: A vacuum insulated glass unit includes a first and a second glass pane and a pane bonding layer. The first and second glass panes each include a vacuum chamber side opposite an outer side. The vacuum chamber side of the first glass pane includes an etched interior surface, a glass pane periphery having a periphery surface, and a plurality of glass spacers each having an end surface. The pane bonding layer is positioned between and engaged with the periphery surface of the glass pane periphery of the first glass pane and the second glass pane and couples the first glass pane to the second glass pane. Each end surface of the plurality of glass spacers and the periphery surface of the glass pane periphery are offset from the etched interior surface such that a vacuum chamber is disposed between the first and the second glass panes.

Abstract: A method of forming a glass laminate includes providing a substrate having a core layer and at least one cladding layer; heat treating the substrate at a temperature such that the at least one cladding layer is phase-separated after the heat treating; and etch treating the substrate for at least 10 sec. A phase-separated glass laminate includes a substrate having a core layer and at least one phase-separated cladding layer, such that the glass laminate has a % transmission of at least 96%, and the at least one cladding layer comprises a grain size in a range of 10 nm to 1 μm, or a graded glass index of greater than 5 nm.
