White chalk crayon. Ceramic decoration with unusual, effective styles and a variety of textures can be created with AMACO® Underglaze Decorating Chalk Crayons.
Chalk Crayons can be used like pastels on bisque pottery, which results in a pebbled appearance. Colors may be blended or smoothed by rubbing with the fingers or a swab of cotton on a toothpick. Water color effects are obtained by brushing sketches with water. For fine lines, the chalk crayons can be sharpened. Small pieces of chalk crayon may be dissolved in water for painting or spraying.
Clear Transparent AMACO® Glazes LG-10, F-10, DC-10, and HF-9 are recommended as a covering glaze. Sponge on first coat of clear glaze lightly in order not to smear design. Let dry and brush on additional coats of clear transparent AMACO® glaze. This precaution is unnecessary if the glaze is to be applied by dipping or pouring. Pieces are fired to the maturing temperature of the covering glaze. When spray application of a covering glaze is desired, first refer to individual listing to be sure that it may be sprayed safely.
