Abstract: A method of modifying a substrate comprising an etching step comprising contacting one or more primary surfaces of a glass, glass-ceramic, or ceramic substrate with a solution for a time period of 20 minutes to 8 hours to generate one or more etched primary surfaces, the solution comprising over 10 percent by weight of one or more alkali hydroxides, the solution having a temperature within the range of 100° C. to 150° C., the substrate having a thickness between the primary surfaces that decreases during the time period by 5 μm to 100 μm at a rate of 2 μm per hour or greater. The solution of the etching step does not comprise hydrogen fluoride. The one or more alkali hydroxides of the solution of the etching step can be sodium hydroxide (NaOH), potassium hydroxide (KOH), or a combination of both sodium hydroxide and potassium hydroxide.

Abstract: A textured glass article that includes: a glass substrate comprising a thickness, a primary surface and a bulk composition at the midpoint of the thickness; and a textured region defined by the primary surface and comprising a textured region composition. The textured region comprises a sparkle of 2% or less. Further, the bulk composition comprises about 40 mol % to 80 mol % silica and the textured region composition comprises at least about 40 mol % silica.

Abstract: A glass article is provided that includes: a glass substrate comprising a thickness and a primary surface; and a textured region defined by the primary surface. The textured region comprises a low spatial frequency region and a high spatial frequency region substantially superimposed within the low spatial frequency region. Further, the low spatial frequency region comprises an average lateral feature size that exceeds an average lateral feature size of the high spatial frequency region. In addition, the textured region comprises a surface roughness (Ra) from about 10 nm to about 1000 nm.

Abstract: A glass substrate comprises: a first surface with surface features having an average width, an average height, a ratio of the average width to the average height of from about 0.04 to about 0.24, and the first surface has a haze value of 3% to 40%. The glass substrate can be transparent to electromagnetic radiation in the visible spectrum. The glass substrate can have a composition of: 61-75 mol. % SiO2; 7-15 mol. % Al2O3; 0-12 mol. % B2O3; 9-21 mol. % Na2O; 0-4 mol. % K2O; 0-7 mol. % MgO; and 0-3 mol. % CaO. The first surface can have an average surface roughness Ra of from 10 nm to 1,000 nm. The first surface can have an average characteristic largest feature size of from 200 nm to 50 μm. The ratio of the average width to the average height can be from 0.06 to about 0.08.

Abstract: Described herein are various systems and methods for using acidic media to enhance the surface characteristics of glass articles while reducing the adverse effects of precipitate/sludge formation. The systems and methods generally implement a precipitation-capturing device that is configured to 1) permit formation of sludge thereon and 2) reduce formation of the sludge on other solid surfaces involved in the systems and methods.
