    • A method of making a strengthened, antimicrobial glass article that includes: providing a glass article comprising a primary surface and ion-exchangeable alkali metal ions; providing a first molten salt bath comprising 60 to 95 wt.% alkali metal ions that are larger in size than the ion-exchangeable alkali metal ions; providing a second molten salt bath comprising alkali metal ions and about 1 to 10 wt.% silver ions; submersing the glass article in the first bath to exchange a portion of the ion-exchangeable alkali metal ions with a portion of the ions in the first bath to define a compressive stress layer extending from the primary surface to a DOL; and submersing the glass article in the second bath to exchange alkali metal ions in the compressive stress layer with a portion of the silver ions in the second bath to impart an antimicrobial property at the primary surface.

    • 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 KNO 3 -containing molten salt bath set at about 380C to about 460C 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 AgNO 3 -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 AgNO 3 -containing molten salt bath and, in some cases, the KNO 3 -containing molten salt bath. Poisoning components include Na + and Li + ions.
