  • Patent number: 9814240
    Abstract: A biocidal additive formulation comprises a silver containing glass particle, and a combination of at least two metal based compounds. A metal in each of the metal based compounds is selected from the group consisting of silver, copper, zinc, mercury, tin, lead, bismuth, barium, cadmium, chromium, titanium, and a combination thereof. Another biocidal additive formulation comprises a silver containing glass particle, ZnO, and Bi2O3. A glass substrate possessing a durable biocidal property and an article possessing a durable biocidal property are also provided.

  • Publication number: 20170258092
    Abstract: A method of making a ceramic glaze formulation having an antimicrobial property for use with a ceramic article. The method comprises fritting an antimicrobial formulation in a flux frit, providing least one unfritted antimicrobial component, providing a silver carrier in a glass matrix, and combining the flux frit, the at least one unfritted component, and the silver carrier in the glass matrix to form the ceramic glaze formulation. The silver carrier is combined at an addition rate based on a dry weight basis of the ceramic glaze formulation. A ceramic glaze additive formulation and ceramic glazed article are also provided.
