Amaco Underglaze Chalk Crayons, Set No. 2 - Set of 8

Create unusual styles and a variety of textures with Underglaze Chalk Crayons by Amaco. A watercolor effect can be obtained by brushing chalk sketches with water. For pastel techniques, draw on bisque ware, then finish with a transparent glaze. Sketching on bisque will result in a pebbled appearance. Underglaze Chalk Crayons can also be blended by rubbing with fingers.

Allow to dry and brush on additional coats as needed. Pieces should be fired to the maturing temperature of the covering glaze.
