Amaco Semi-Moist Deco Colors (Set of eight)
Semi-Moist Underglaze Decorating Colors -- LEAD FREE
Semi-Moist Underglaze decorating colors are suitable for many types of ceramic painting. They are especially good for water color effects and painting of fine detail. The 32 colors are concentrated, intense and opaque. Additional shades and tints are made by intermixing. Colors may be brushed on either greenware or bisqueware. A brush dipped in water lifts the color for decorating. Further thinning of the water soluble colors prepares them for transparent water color effects by brushing. Colors are approximately the same tone before and after firing, so effectiveness of color combinations and blending can be observed as painting progresses. Colors dry quickly and may be handled without damage. If applied to bisque, sponge the first clear coat to avoid smearing. Glazes with Zinc can cause discoloration of underglazes. Use of Zinc-free covering glazes is recommended. All colors are non-toxic.
Pieces are fired to the maturing temperature of the covering glaze. Pink, maroon, peach, rose and yellow hold their color when fired to temperatures up to Cone 6 (2269°F, 1243°C). All other colors may be fired to an upper limit of Cone 10 (2381°F, 1305°C) with good retention. AMACO Semi-Moist Underglaze Decorating Colors have only been tested and approved as dinnerware safe when applied and fired under AMACO LG10 Clear Glaze. They should not be used on surfaces which come in contact with food or drink. If left unglazed, AMACO clear glazes LG10, F10 or any other dinnerware safe glaze are recommended to be used over AMACO Semi-Moist Underglaze Decorating Colors to make them dinnerware safe.
