Beschreibung
Zusammenfassung:	A method of making an antimicrobial glass article that includes the steps: submersing the article in a strengthening bath to exchange a portion of ion-exchangeable metal ions in the glass article with a portion of ion-exchanging metal ions in the strengthening bath to form a compressive stress layer extending from the first surface to a diffusion depth in the article; removing a portion of the compressive stress layer from the first surface of the article to a first depth above the diffusion depth in the article to define a new first surface and a remaining compressive stress layer; and submersing the article in an antimicrobial bath to exchange a portion of the ion-exchangeable and the ion-exchanging metal ions in the compressive stress layer with a portion of the silver metal ions in the antimicrobial bath to impart an antimicrobial property in the article.
