By jolly or jigger: They are instruments made to hold a template in relation to the clay being turned on the wheel. They must be very stable and for this reason are usually attached to a wall. A mold is put on to a wheel and centered, the clay laid over it or into it. The template is held in a jigger or jolly, placed against the clay then the wheel is slowly turned and the template scrapes and removes the unnecessary clay until it forms the shape of the template.
