Often, particularly in functional ware, it is covered with a clear or translucent glaze. Amaco Liquid Underglaze Decorating Colors are concentrated, opaque colors recommended for covering large areas quickly, easily and smoothly. Results are equally effective when the colors are used for detailed painting, sgraffito decoration, water color effects, free brush painting, wax resists and mishima decoration. Colors may be brushed on greenware which is to be bisque fired before applying a covering glaze, or on mature Cone 04 bisque, then covering glaze applied and fired to maturity temperature of the clear glaze. Also use for coloring slip or clay.
Velvets are a very versatile, semi-translucent underglaze which offers two finish possibilities.
When left unglazed they have the appearance of velvet. Or, when glazed with a clear gloss glaze, they have a soft, satin matt finish. They are rich colors and can be used for all over coverage similar to an opaque underglaze. Colors may be mixed together to create unique colors. Use on greenware, then bisque prior to applying a clear glaze.
