Twenty-four Easy-to-Apply Colors. Twenty-four 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, (2) on mature Cone 04 bisque, then covering glaze applied and fired to maturing temperature of the clear glaze. Color chips shown above were glazed with LG-10 and fired to Cone 05.For opaque coverage by brushing, the consistency of the color in the jar is correct. White slip may be tinted by adding small amounts of most LUG colors to produce colored slip. Intensity depends on quantity used. To color moist clay, cut clay in very thin slices, pour LUG color between slices and wedge until 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.Transparent covering glazes are applied on decorated bisque shapes, and the pieces are fired to the maturing temperature of the glaze. AMACO® Glazes LG-9, LG-10, F-10 and HF-9 are recommended as clear glazes. LUG-25 will appear Green Turquoise under LG-9 and Blue Turquoise under LG-10. Colored transparent glazes in the LG, F and HF series may be selected for unusual effects.
