Abstract: Disclosed herein are dual-textured glass articles. The glass articles may include a glass substrate comprising a first major surface and a second major surface. The first major surface may be opposite the second major surface. At least a portion of the first major surface comprises a dual-texture. The dual-texture may comprise a plurality of first features and a plurality of second features. The plurality of first features comprise protrusions from the first major surface and the plurality of second features comprise indentations in the first major surface and indentations in the plurality of first features.

Abstract: Anti-sparkle substrates include a first major surface with a textured surface having a surface roughness Ra from 0.03 micrometers to 0.09 micrometers. The anti-sparkle substrate is a glass-based substrate or a ceramic-based substrate. The anti-sparkle substrate can exhibit a haze from 3% to 40% and a sparkle from 1% to 3.8%. Methods include chemically strengthening an existing first major surface, abrading the existing first major surface to form an intermediate first major surface, and etching the intermediate first major surface to form the first major surface of the anti-sparkle substrate.

Abstract: A textured article is described herein that may include a glass-based substrate comprising a first major surface and a second major surface. The first major surface may be opposite the second major surface. At least a portion of the first major surface may be textured. The portion of the first major surface that is textured may have a roughness Ra of greater than or equal to 400 nm and an average pitch. A ratio of roughness Ra to average pitch may be from about 0.01 to about 0.04. At least a portion of the textured article may have an opacity of greater than about 70% or may have a coefficient of friction of from about 0.25 to about 0.4. The coefficient of friction may be measured as the kinetic coefficient of friction using a 500 g load on a foam rubber according to ASTM D1984.

Abstract: A method of forming a textured glass article comprises: submerging an aluminosilicate glass article in an etchant to an upper submerging depth from a surface of the etchant and at a tilting angle, wherein the aluminosilicate glass article comprises a first major surface and a second major surface opposite the first surface, wherein the tilting angle is a smallest angle between a normal to the first major surface and a vertical; holding the aluminosilicate glass article in the etchant for a holding time; and after the holding time, cycling the aluminosilicate glass article in the etchant between the upper submerging depth and a lower submerging depth deeper than the upper submerging depth for a cycling time.
