Prepared by the interaction of sodium nitrate and potassium chloride. It is used in glazes, glass and enamels for its oxidizing and fluxing properties.

Oxidation enamels usually contain 2-4% potassium or sodium nitrate to maintain oxidizing conditions during smelting to prevent reduction of compounds such as lead or antimony. Enamels with niter thus tend to froth during melting.
