Velvet Underglazes - Lead Free 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. |
