Lead Free Velvet Underglazes - 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 an AMACO 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 very rich 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.
Velvets were developed to be used without a glaze cover. They should not be used on surfaces which come into contact with food or drink. AMACO glazes LG-9, LG-10, F-10, DC-10, and HF-9 are recommended as clear glazes over Velvets. V-327 will appear Green Turquoise under LG-9 and Blue Turquoise under LG-10.
Designer Velvet Underglazes - Designer Velvets are semi-translucent underglazes that have the same distinction as the original Velvet line with the addition of small specks. When left unglazed, they assume the appearance of velvet or velour with a soft speckle effect. When glazed with AMACO® Transparent Matte or Clear Glazes, they intensify slightly in color.
Designer Velvet colors can be used on greenware or bisque. All colors are lead free. Recommended bisque firing range is Cone 04, but Designer Velvets tolerate a wide firing range with recommended firing temperature being that of the clay used.
