Publication number: 20150118276Abstract: The disclosure is directed to a chemically strengthened glass having antimicrobial properties and to a method of making such glass. In particular, the disclosure is directed to a chemically strengthened glass with antimicrobial properties and with a low surface energy coating on the glass that does not interfere with the antimicrobial properties of the glass. The antimicrobial has an Ag ion concentration on the surface in the range of greater than zero to 0.047 ?g/cm2. The glass has particular applications as antimicrobial shelving, table tops and other applications in hospitals, laboratories and other institutions handling biological substances, where color in the glass is not a consideration.Type: ApplicationFiled: January 6, 2015Publication date: April 30, 2015Inventors: Nicholas Francis Borrelli, David Lathrop Morse, Wageesha Senaratne, Florence Christine Monique Verrier, Ying Wei
