Abstract: Glasses that can be chemically strengthened and are colored by transition metals. Most of the glasses are black, with some having high damage resistance and compressive surface layers having high compressive stress and depth of layer after ion exchange. These colored glasses do not require a post-forming heat treatment to produce color and are formable by fusions drawing, rolling, slot drawing, and float glass processes.

Abstract: A glass article including at least about 40 mol % SiO2 and, optionally, a colorant imparting a preselected color is disclosed. In general, the glass includes, in mol %, from about 40-70 SiO2, 0-25 Al2O3, 0-10 B2O3; 5-35 Na2O, 0-2.5 K2O, 0-8.5 MgO, 0-2 ZnO, 0-10% P2O5 and 0-1.5 CaO. As a result of ion exchange, the glass includes a compressive stress (σs) at at least one surface and, optionally, a color. In one method, communicating a colored glass with an ion exchange bath imparts σs while in another; communicating imparts σs and a preselected color. In the former, a colorant is part of the glass batch while in the latter; it is part of the bath. In each, the colorant includes one or more metal containing dopants formulated to impart to a preselected color. Examples of one or more metal containing dopants include one or more transition and/or rare earth metals.

Abstract: A glass article comprising an alkali aluminosilicate glass that is formable by down-draw processes for example slot- and fusion-draw to thicknesses of 125 μm or less and is capable of being chemically strengthened by ion-exchange to achieve a compressive stress at its surface of at least 950 MPa, in some embodiments at least about 1000 MPa, and in other embodiments at least about 1100 MPa. The high surface compressive stress allows the glass to retain net compression and thus contain surface flaws when the glass is subjected to bending around a tight radius. The glass may be used in foldable display applications.

Abstract: A glass article includes a glass core layer and a glass cladding layer adjacent to the core layer. A coefficient of thermal expansion (CTE) of the core layer is greater than a CTE of the cladding layer. The core layer has a tensile stress, and the cladding layer has a compressive stress. A retained strength of the glass article is a strength determined after abrasion of an outer surface of the glass article with 1 mL of 90 grit SiC particles for 5 seconds at an abrasion pressure, and a ratio of the retained strength at an abrasion pressure of 25 psi to the retained strength at an abrasion pressure of 5 psi is at least about 0.3.
