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.

A glass-based article with a textured surface exhibiting low haze is provided. The glass-based articles are produced by utilizing a combination of abrasion and etching, where hydrofluoric acid is not utilized. The process for producing the glass-based articles also includes an ion exchange process.

A textured glass article includes: a body comprising an aluminosilicate glass comprising greater than or equal to 16 wt % Al.sub.2O.sub.3, the body having at least a first surface; a plurality of dendritic surface features extending from the first surface, each of the plurality of dendritic surface features comprising a base on the first surface and a surface feature size at the base greater than or equal to 10 μm and less than or equal to 350 μm; and a transmittance haze greater than or equal to 50%.

The purpose of the present invention is to provide a chemically-strengthened glass exhibiting both surface strength and abrasion-resistant anti-fingerprint (AFP) properties. The present invention relates to a plate-shaped chemically-strengthened glass which has a compressive stress layer provided to a glass surface layer, a glass surface hydrogen concentration profile in a specific range, and a surface strength and abrasion-resistant anti-fingerprint (AFP) properties which are in specific ranges.

A coated glass article includes a glass article comprising a glass having a surface. The surface has an adhesion promoting region comprising a nanostructure formed at the surface of the glass. The adhesion promoting region is constructed of materials that are the same as one or more constituents of a glass composition of the glass. The coated glass article further includes a coating disposed on the adhesion promoting region formed at the surface of the glass. The coating incudes one or more polymer coating materials. The adhesion promoting region improves adhesion of the coating to the glass while also eliminating the use of titania or other adhesion promoting compounds that can adversely affect the optical properties of the coatings.

A system and method of production of matt effect or matt glass that eliminates the double-sided printing process in the production process of glasses used in products such as ovens, refrigerators, bottle cabinets, combi boilers, built-in appliances, fume hoods, stove glass, etc., prevents fingerprints on glass and increases the scratch resistance.
