Potter's wheel
Many early ceramics were hand-built using a simple coiling technique in which clay body was rolled into long threads that were then pinched and beaten together to form the body of a vessel. In the coiling method of construction, all of the energy required to form the main part of a piece is supplied directly by the hands of the potter. This changed with the introduction of the fast-wheel, early forms of which used energy stored in the rotating mass of the heavy stone wheel itself.
