Brilliant, Ready-To-Use Colors. Amaco® Liquid Underglaze Decorating Colors are supplied in time-saving, ready-to-use form. The concentrated, opaque colors are recommended for covering large areas quickly, easily, and smoothly. 25 intense colors are available and other colors, shades and tints are made by blending. The colors may be brushed: (1) on greenware, which is to be bisque fired before applying a covering glaze, or (2) on bisque, then covering glaze applied. For opaque coverage by brushing, the consistency of the color in the jar is correct. Slip may be tinted by adding small amounts of LUG to produce colored slip. Intensity depends on the quantity used. To color moist clay, cut clay in very thin slices, pour LUG color between slices and wedge until a uniform color is achieved.
Since the colors are approximately the same tone before and after firing, the effectiveness of color combinations and blending is observed as the painting progresses.
