    摘要: 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.
