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.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
