Create cool patterns in clay! Molds facilitate the creation of textured, embossed and decorative clay surfaces. Just press moist clay onto the porous plaster molds then lift and either hand-build or add the textured clay to already thrown pots. Textured designs can enhance artwork, both in terms of adding imagery as well as affecting the glaze and underglaze colors. Recommended for water-based clays only. Since the plaster naturally absorbs water and releases the clay, no release agent is needed. Sprig Molds are used to easily add decorative elements and embellishments to moist clay projects. Mold is 1-1/4" thick and measures 12 x 6-3/4".
