AMACO Velvet Underglazes

AMACO Velvet Underglazes

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 (1020°C-1040°C)  underglaze or fired to Cone 6 (1230°C). Some colors remain true as high as Cone 10 (1300°C).

Try two finish possibilities: When left unglazed these colors have the rich textural appearance of velvet; when covered with AMACO clear transparent matte of Clear Gloss they intensify in color. Can be easily applied to wet clay, greenware, or mature Cone 04 bisque (1060°C)

Some colors can develop anaerobic bacteria with stinky smell in the container. You can add a few drops of bleach or vinegar to your underglaze to stop this. 

Cadmium containing colors (some of the bright red, yellow and orange colors) might cause glaze defects (bubbles) when fired with zinc-free glazes to 1230°C or more. We recommend to us HF-10 Clear glaze in that case.
