Painted on a wheel designs are incised through the paint layer into the clay pots. The score line, made with fine carving tools, become part of the design and the resulting art piece is called Sgraffitto. Etched art is done on either red terracotta clay or white gypsum greenware clay pots that have been made in a mold. After being fired, the resulting design will show the bright white background or the earth-colored red backgrounds seen on the various pieces throughout our store. Call for wholesale packages.
