An antimicrobial chemically strengthened glass and a method for manufacturing the antimicrobial glass article. The antimicrobial chemically strengthened glass is suitable for use as high-strength cover glass for touch displays.

A method of making a glass having antimicrobial properties and high compressive stress. The method includes a first ion exchange step in which potassium cations are exchanged for sodium cations in the base glass to provide a surface layer under compressive stress, followed by a second ion exchange in which silver cations are exchanged for potassium and lithium ions in the glass to produce the antimicrobial glass. In some embodiments, the antimicrobial glass has a maximum compressive stress that is at least 80% of the maximum compressive stress obtained by the potassium-for-sodium exchange in the first bath. A base glass and an ion exchanged glass antimicrobial having antimicrobial properties are also provided.
