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: Anti-glare glass-based articles and methods of processing a glass based article to reduce warp are disclosed. A method for processing a glass-based article includes etching a first surface of the glass article to create a first anti-glare surface having a plurality of first anti-glare features and etching a second surface of the glass-based article to create a second anti-glare surface having a plurality of second anti-glare features. At least one of a length, a width, and a diagonal of the glass-based article is greater than or equal to 500 mm. A difference of warp between a first warp value before etching the first surface and the second surface and a second warp value after etching the first surface and the second surface is less than or equal to 0.15 mm across each of one or more 500 mm intervals of length, width, or diagonal of the glass-based article.
