Patent number: 11767256Abstract: A method of making a ceramic glaze additive formulation having an antimicrobial property for use with a ceramic article is provided. The method comprises fritting an antimicrobial formulation in a flux frit, providing a silver carrier in a glass matrix, combining the flux frit and the silver carrier in the glass matrix to form the ceramic glaze additive formulation, wherein the silver carrier is combined at an addition rate of at least 2 weight %, based on a dry weight basis of the ceramic glaze formulation. The flux frit is present in the ceramic glaze additive formulation in a range of 94 weight % to 99.5 weight %, based on a dry weight basis of the ceramic glaze additive formulation. A ceramic glaze additive formulation and a ceramic glazed article comprising a ceramic glaze additive formulation are also provided.Type: GrantFiled: December 16, 2020Date of Patent: September 26, 2023Assignee: MICROBAN PRODUCTS COMPANYInventors: Alvin Lamar Campbell, Jr., Nathan L.
