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.
Clear Transparent AMACO® Glazes LG-10, F-10, DC-10, and HF-9 are

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.
