Radiant Red Velvet Underglaze is a bright scarlet color that is vivid at cone 05, deepens at cone 5, and becomes a slightly glossy, deep fire-engine red at cone 10. A clear glaze accentuates the color of the underglaze nicely at any temperature.

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