Purple Liquid Underglaze is a soft purple color that is light and powdery at cone 05, becomes more of a creamy light blue and fluxes into a soft glaze-like surface at cone 6, and begins to burn out at cone 10. Though the underglaze does become glaze-like, a clear gloss glaze can give Purple an impeccably smooth surface with intensified color, but will cause more color loss at higher temperatures.
