![HUMP MOLD 12"](http://psh.ca/cdn/shop/products/TMH12_{width}x.jpg?v=1590633037)
12" dia. x 6" deep. Fit onto standard 10" centered wheel head pins. Simply lay a slab of clay on top of the hump mold. Think of it as throwing the backside of a form. You will still have to throw a foot by gathering clay from the slab or by attaching a coil and compressing it to the back.
