Maroon Liquid Underglaze is a plum color that is a light burgundy at cone 05, becomes a beautiful, deep mauve 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 Maroon an impeccably smooth surface with good color, but will cause more color loss at higher temperatures.
