Warm Gray Liquid Underglaze is a soft gray that is light and smoky at cone 05, becomes deeper gray and fluxes into a soft glaze-like surface at cone 6, and maintains a slate gray tone with a soft sheen all the way to cone 10. Though the underglaze does become glaze-like, a clear gloss glaze can give Warm Gray an impeccably smooth surface with good color.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
