Abstract: Disclosed herein are glass-ceramic article having a first surface, a second surface opposing the first surface, a first region extending from the first surface to a first depth d1, and a second region extending from a depth greater than or equal to d1 to a second depth d2, wherein the second region comprises a crystalline phase and a glass phase, and wherein an area percentage % of crystals in the first region is less than an area percentage % of crystals in the second region. In some embodiments, a compressive stress layer extends from the first surface to a depth of compression (DOC), wherein the DOC is greater than or equal to 0.05 mm an average compressive stress in the first region is greater than or equal to 50 MPa. In some embodiments, the DOC is greater than d1; a reduce modulus of the first region is less than the reduced modulus of the second region; and/or a hardness of the first region is less than the hardness of the second region.

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.
