Amaco Underglaze Pencils Now more intense, with better working qualities. Underglaze Decorating Pencils are ideal for shading, fine line drawing or identification. Apply the underglaze pencil to bisque ware to create a variety of unique decorative designs. After decorating, dust lightly with a brush to remove excess particles. Sponge on first coat of clear glaze lightly, in order not to smear design. Let dry and brush additional coats of clear transparent AMACO® glaze. This precaution is unnecessary if the glaze is to be applied by spraying, 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 it may be sprayed safely. Unlike regular pencils—care must be taken in sharpening Underglaze Pencils. Do not use a pencil sharpener. It is best to sharpen the underglaze pencil with a knife or blade. NOTE: The maximum firing temperature is Cone 10 for Blue, Black, and Green, Cone 5 for Brown and Yellow, and Cone 05 for Rose. If left unglazed, AMACO® Underglaze Pencils should not be used on surfaces which come in contact with food or drink. AMACO® clear glazes LG-10, F-10, and HF-9 or any other dinnerware safe glaze are recommended to be used over AMACO® Underglaze Pencils to make them dinnerware safe. AMACO® Underglaze Pencils have only been tested and approved as dinnerware safe when applied and fired under LG-10 Clear Glaze. To reduce smudging, mix 1 tablespoon AMACO® Gum Solution to 1 pint of water in spray bottle. Spray on work before glazing.
