Abstract: Methods of forming vias in a glass-based article by laser-damage-and-etch processes including etching solutions having positive charge organic molecules are disclosed. In some embodiments, a method of forming a via in a glass-based article includes forming a damage track through a bulk of the glass-based article extending from a first surface of the glass-based article to a second surface of the glass-based article, and applying an etching solution to the glass-based article to form the via. The etching solution includes at least one acid and a positive charge organic molecule. An etch rate at the first surface and the second surface is lower than an etch rate at the damage track.

Abstract: Methods for regenerating poisoned salt bath comprising providing a salt bath comprising at least one of KNO3 and NaNO3, providing an ion-exchangeable substrate comprising lithium cations, contacting at least a portion of the ion-exchangeable substrate with the salt bath, whereby lithium cations in the salt bath diffuse from the ion-exchangeable substrate and are dissolved in the salt bath, and selectively precipitating dissolved lithium cations from the salt bath using phosphate salt. The methods further include preventing or reducing the formation of surface defects in the ion-exchangeable substrate by preventing or reducing the formation of crystals on the surface of the ion-exchangeable substrate upon removal from the salt bath.

Abstract: Described herein are various antimicrobial soda lime glass articles that have improved resistance to discoloration when exposed to harsh conditions, including manufacturing conditions. The improved antimicrobial glass articles described herein generally include a SLG substrate that has a thickness, t; a compressive stress layer of about 0.15*t or greater; and an antimicrobial agent-containing region having an antimicrobial agent and a thickness less than the thickness of the compressive stress layer. Roughly 2 to 20 microns of the primary surfaces of the glass substrate can be removed prior to development of the compressive stress and antimicrobial agent-containing region. In some aspects, prior-annealed and tempered, or prior-annealed, SLG is employed as the substrate. In some aspects, the substrate includes tin at one surface. The improved SLG substrates experience substantially no discoloration when exposed to harsh conditions. Methods of making and using the glass articles are also described.

Abstract: A patterned article that includes: an alkali silicate glass substrate comprising a thickness and a primary surface, the substrate having a bulk composition; a patterned region defined by at least a portion of the primary surface; and a compressive stress region that extends from the at least a portion of the primary surface to a first depth within the substrate. The patterned region comprises a surface roughness (Ra) from about 1 nm to about 600 nm and at least one of a plurality of protrusions and a plurality of depressions. Further, each of the compressive stress region and the patterned region comprises a concentration of at least one alkali metal ion that is different than the concentration of the at least one alkali metal ion in the bulk composition.

Abstract: Described herein are various antimicrobial articles that have reduced discoloration after the formation of a silver-containing region in a substrate. The improved antimicrobial articles described herein generally include a substrate that comprises a compressive stress layer and a silver-containing region that each extend inward from a surface of the substrate to a specific depth, and has a uniform silver concentration profile across the surface of the substrate, such that the article exhibits little-to-no discoloration. Methods of making and using the articles are also described.
