Straw Velvet Underglaze is a rich sunflower yellow that is a strong ochre at cone 05 and becomes lighter at cone 5. At cone 10, it is even lighter and less saturated. Overall, it maintains its color well at any temperature and becomes richer and darker under a clear glaze.
If AMACO Velvets are used for food or drink, they must be covered by a dinnerware-safe clear glaze and fired properly.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
