A potter's wheel is a tool used by potters to shape clay into various forms, such as bowls, vases, and plates. It consists of a rotating disk that the potter spins while molding the clay with their hands. The wheel allows for precise control and symmetry in the creation of pottery. There are two main types of potter's wheels: the kick wheel, which is powered by foot, and the electric wheel, which uses an electric motor. Both types enable potters to create functional and artistic pieces, making the potter's wheel an essential instrument in the craft of pottery.
