Shop here for slump molds, which are concave forms that you can drape slabs of clay into. When you work with slump molds, the interior of your form is exposed, while the outer face is in contact with the mold. That means if you like to make forms such as platters with a decorated surface, this may be the mold type for you! We carry a wide variety of different shapes of slump molds that we produce here at The Ceramic Shop. Made of highly durable HydroStone -- the same materials that our Hydrobats are made of -- these molds make a great addition to any studio or classroom.
