Abstract: Methods for compensating for warp typically exhibited by glass-based articles having non-uniform thicknesses as a result of ion exchange strengthening are provided. The methods include producing a molding surface of a mold based on a measurement of warp obtained by a specified ion exchange strengthening of a glass-based substrate of non-uniform thickness, such that the molding surface offsets the warp. Glass-based substrates resulting from the mold can then be exposed to the specified ion exchange strengthening and form glass-based articles that are substantially free of warp.

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 method of making a strengthened glass article includes providing a flat glass article having a select contour and a glass surface covered by a protective coating layer. The protective coating layer is removed from the glass surface without touching the glass surface with any solid object. Immediately after the protective coating layer is removed from the glass surface, the flat glass article is subjected to an ion-exchange process to strengthen the flat glass article and improve the resistance of the flat glass article to subsequent damage.
