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.

Ceramic additive formulation and method of making

A method of treating a glazed ceramic article comprises applying an antimicrobial composition on top of an outermost surface of a glazed ceramic article. The antimicrobial composition comprises an antimicrobial additive. The antimicrobial composition further comprises a carrier medium. The antimicrobial additive is selected from the group consisting of BiO, ZnO, AgCO, AgO, Zn, Bi, Ag, and a combination thereof.

Method of treating a glazed ceramic article

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.
