Lead-free Amaco Velvets are semi-translucent underglazes which have the appearance of velvet when left unglazed.
Velvets will become opaque after three coats. When glazed with transparent matte glaze they will assume a soft, satin finish. The colors will intensify when covered with a clear transparent gloss glaze, but will lose their matte surface quality.
Velvets fire true to color from the jar and may be intermixed with other colors. They may be brushed on mature fired bisque before applying a covering glaze. These underglazes are safe for spray application. Velvets tolerate a wide firing range. Fire to Cone 06-10 (1855°F–2381°F, 1013°C–1305°C).
Colors can be assorted by size for quantity pricing.
Some colors vary at higher temperatures. Please refer to the Resources tab of this page to download a PDF of Amaco's color variation chart for colors at Cone 05 and Cone 10.
Note — Velvets were developed to be used without a glaze color and should not be used on surfaces which come into contact with food or drink.
Note — Use this color chart as an approximation of the real color. If exact color matching is necessary, use actual samples of the materials.
