    Abstract: Described herein are various methods and manufacturing methods for making antimicrobial and strengthened, antimicrobial glass articles and substrates. The methods described herein generally include contacting the article with a KNO3-containing molten salt bath set at about 380 C to about 460 C for about 30 minutes to about 24 hours to form a compressive stress layer that extends inward from a surface of the glass substrate to a first depth; and contacting the article comprising the compressive stress layer with a AgNO3-containing molten salt bath set at about 300° C. to about 400° C. for about 5 minutes to about 18 hours to form an antimicrobial region that extends inward from the surface of the glass substrate to a second depth. The methods also include poisoning at least the AgNO3-containing molten salt bath and, in some cases, the KNO3-containing molten salt bath. Poisoning components include Na+ and Li+ ions.

    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 method for optimizing ion exchange of glass. The glass is ion exchanged in a series of two ion exchange baths. The first ion exchange bath contains an amount of a poisoning ion or salt and the second ion exchange bath contains an amount of the poisoning ion or salt that is less than that in the first bath. When the concentration of the poisoning ion/salt in the first bath reaches a maximum value, the first bath is discarded and replaced by the second bath and a third bath that initially does not contain the poisoning cation/salt replaces the second ion exchange bath. This cycling of baths may be repeated to produce a plurality of glass articles, each having a surface layer under a compressive stress and depth of layer that are within predetermined limits.

    Abstract: Provided herein is a method for producing glass-ceramic sheets. The method includes texturing at least one surface of a first glass sheet, and stacking the first glass sheet and a second glass sheet. The first glass sheet and the second glass sheet are stacked so that the textured surface of the first glass sheet contacts a surface of the second glass sheet. The first and second glass sheets are cerammed. After cooling, the cerammed first and second glass sheets are separated. Also provided is a pre-form for producing glass-ceramic sheets. The pre-form includes a first glass sheet having a textured surface, and a second glass sheet contacting the first glass sheet. The textured surface of the first glass sheet is in contact with a surface of the second glass sheet.
