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: Described herein are textured glass-based articles. The textured glass based articles may include a glass-based substrate including a first major surface and a second major surface. At least a portion of one or both of the first major surface and the second major surface is textured, wherein the portion of the one or both of the first major surface and the second major surface that are textured may have a sparkle at 140 ppi of less than or equal to 5% and an uncoupled distinctness-of-image of at least 78%. Methods for making such articles are also described herein.
