    Abstract: A textured article is described herein comprising a substrate comprising a textured region defined on a primary surface of the substrate, in which the textured region comprises (a) a Vmp/Sq of at least 0.084, (b) a Vmp/Sq of at least 0.084 and an Smrk2 of at least 90%, and/or (c) a Vmp of at least 10 nm and an Sdq of 0-0.1. The textured article generally has good abrasion resistance and optical properties including antiglare, haze, sparkle, and distinctness of image. A method for making a textured article is also described herein comprising removing a first portion of a primary surface of a substrate through holes penetrating through a stop layer to the primary surface to form seed depressions and unremoved portions, removing the stop layer, and then removing a second portion of the primary surface comprising the seed depressions and the unremoved portions.

    Abstract: Glass-based substrates are described herein that may be processed by methods including applying a cover article onto a glass-based substrate, submerging the glass-based substrate in an etchant, and maintaining the submersion of the glass-based substrate in the etchant. The glass-based substrate may include a covered surface portion and an exposed surface portion. At least a portion of the covered surface portion may be in direct contact with the cover article. The covered surface portion may not be in contact with the etchant and the exposed surface portion may be in direct contact with the etchant. The etchant may contact the exposed surface portion and the cover article fora time sufficient to etch the exposed surface portion. The cover article may provide a barrier between the etchant and the covered surface portion for the entirety of the submerging.

    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.
