Mayco – Slump and Hump Mold Sets – Circle
Plaster Slump and Hump Molds from Mayco are sold as a set (one hump and one slump). Slump molds allow you to drape a slab into the form and work on the inside of the finished piece while the clay is still on the mold. Hump molds allow you to drape a slab over the mold and work on the outside of the finished piece while the clay dries. Plaster is porous and therefore absorbs water from the wet clay so it will set faster.
