To remove larger pottery from the potter's wheel requires a device called a mold. In fact, each pottery needs a mold and it is better to always have a number of molds ready.
The mold is a round earthenware or wooden plate that is exactly the size of a pillowcase. The only difference is the thickness of the mold, which is slightly thinner than the steering wheel on the wheel. Keep in mind that molds must be used to make pottery the size of a vase and larger. Otherwise you will have trouble removing the pottery.
