For V-388 Radiant Red Velvet Underglaze, we recommend using HF-9 Zinc Free Clear. If HF-10 Clear is used, color may shift. 

HF-9 Zinc-Free Clear is recommended for use with underglazes to reduce the incidence of color shift. Most underglazes, stains, and coloring oxides will show their best color with Zinc-Free Clear.

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

Saturated color, dependability, and versatility make Velvets as popular for professionals as they are for children. Velvets fire true-to-color as a Cone 05/06 underglaze or fired to Cone 6.
Some colors remain true as high as Cone 10.

Try two finish possibilities: When left unglazed these colors have the rich textural appearance of velvet; when covered with AMACO Clear Transparent Matte or Clear Gloss they intensify in color. Can be easily applied to wet clay, greenware, or mature Cone 04 bisque (1971F / 1077C)
