All colors in the Velvet Series are AP NON-TOXIC.
AMACO Velvets semi-translucent underglazes offer two finish possibilities. When left unglazed, they have the appearance of velour or velvet. They will intensify in color when covered with a Clear Transparent Gloss glaze.
Velvets 380-384 have a unique formula that makes them very versatile. They can be used in detailed design work as a Cone 05/06 underglaze, or they can be fired up to Cone 6 and maintain their intensity and brightness.
All the Velvets are vibrant colors and can be used for an all-over coverage similar to an opaque underglaze. They fire true to color as applied from the jar and may be intermixed to create a palette of hundreds of colors. The colors may be brushed (1) on greenware, which is to be bisque fired before applying a covering glaze, or (2) on a mature Cone 04 (1971 F, 1077 C) bisque, then a covering glaze applied. For opaque coverage by brushing, the consistency of the color in the jar is correct. Velvets tolerate a wide firing range, with recommended firing temperature being that of the clay used.
