Product Description:

Recommended for use with wet clay. Form clay slabs over the shape and allow to dry for 2-3 hours, or until the clay releases itself from the mold. Drying time will vary - the clay is ready to remove once it has released itself and you can handle it without breaking. Once formed, allow clay to dry before firing.
Not recommended for use in a kiln.
