Elephant Velvet Underglaze is a light, ashy shade when fired to cone 05, darkens to a deeper gray at cone 5 then turns to a grayish-black akin to elephant skin when fired to cone 10. A clear glaze accentuates the color of the underglaze significantly at any temperature.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
