Amaco Velvet UnderglazesAMACO®Velvet Underglazes are 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 Transparentor Gloss glaze. V-387 Bright Red, V-388 Radiant Red, V-389 FlameOrange, V-390 Bright Orange, and V-391 Intense Yellow, are the latest addition of very bright colors. These colors, when applied and fired,have a very vivid, luminescent glow.
Velvets V-380 through V-384 and V-387 through V-391 are formulated with encapsulated red, orange, and bright yellow pigmentswhich make them very color/temperature stable. 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 similarto an opaque underglaze. They fire true to color as applied from thejar and may be intermixed to create a palette of hundreds of colors.
The colors may be brushed on greenware which is to be bisque fired before applying a covering glaze or 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. To see how Velvets look when fired to Cones 5 and 10, click here for the web page or download the PDF above.
