Abstract:
Described herein are various antimicrobial glass articles that have improved resistance to discoloration when exposed to harsh conditions. The improved antimicrobial glass articles described herein generally include a glass substrate that has a low concentration of nonbridging oxygen atoms, a compressive stress layer and an antimicrobial silver-containing region that each extend inward from a surface of the glass substrate to a specific depth, such that the glass article experiences little-to-no discoloration when exposed to harsh conditions. Methods of making and using the glass articles are also described.

Claim (Index 6):
A method of making an antimicrobial glass article, the method comprising:\n providing a glass substrate; forming a compressive stress layer that extends inward from a surface of the glass substrate to a first depth; forming an antimicrobial silver-containing region that extends inward from the surface of the glass substrate to a second depth; and chemically cleaning the glass substrate after the forming steps by contacting the glass substrate with a cleaning solution at an ambient temperature for less than or equal to about 15 minutes, wherein the cleaning solution comprises any one of:\n less than or equal to about 2 volume percent each of ammonium hydroxide and hydrogen peroxide in water, based on a total volume of the cleaning solution; \n about 0.01 wt % to about 5 wt % sodium chloride in water, and \n about 0.01 wt % to about 5 wt % citric acid in water.
