    Abstract: A method is described herein of making a textured glass article, the method includes: etching an initial primary surface of a glass substrate having a thickness with a hydrofluoric acid-free etchant having a pH of about 3 or less; and removing the etchant from the glass substrate, such that the etching is conducted from above ambient temperature to about 100° C. to form a textured region that is defined by a primary surface of the substrate and comprises a sparkle of 2% or less, and the etching comprises a plurality of batch cycles.

    Abstract: Methods for making a glass article include etching the surfaces of the glass article with an etchant solution that includes hydrofluoric acid to produce an etched glass article. The glass article being a high index glass containing transition metal oxides and having an index of refraction greater than or equal to about 1.6 at 589.3 nm wavelength. The surface having surface and subsurface defects. The etching improves a surface strength of the surfaces of the etched glass article by removing or rounding the surface and subsurface defects, and the etching causes deposition of transition metal fluorides. The methods include cleaning the surfaces of the etched glass article with a cleaning solution having a pH of greater than or equal to about 10 to remove transition metal fluorides from the surfaces of the etched glass article.

    Abstract: One or more aspects relate to an article that includes a glass substrate having a first average strain-to-failure; and a crack mitigating layer disposed on a first major surface of the substrate forming a first interface. The article also includes a film disposed on the crack mitigating layer forming a second interface and having a second average strain-to-failure that is less than the first average strain-to-failure. Further, at least one of the first and second interfaces exhibits a moderate adhesion such that at least a portion of the crack mitigating layer experiences one or more of a cohesive failure and an adhesive failure at the interfaces when the article is strained to a strain level between the first average strain-to-failure and the second average strain-to-failure. In addition, the refractive index of the crack mitigating layer is between or the same as the refractive indices of the substrate and the film.
