Coil method or coil construction
Coils are long, snake-like ropes of clay that are used in making pottery. The coil method of making pottery involves building the walls of a pot with a series of coils into the required shape. Once the desired height has been reached the surface can either remain coil-textured or they can be smoothed. Much pottery in primitive cultures was made this way, and remains one of the principle hand-building technique potters use.Also see helix, pinch, slab construction, potter's wheel, and volute.
