Ceramic decoration with unusual, effective styles and a variety of textures can be created with AMACO Underglaze Decorating Chalk Crayons. The 2 3/4" x 7/16" chalk crayons come in sixteen colors ranging from intense hues to pastel tones. 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.
