Jiggering is another method for mass production. A ball of clay is placed into a jigger mold and then is pressed by a wheel head to form the shape. Once the pot is leather hard, it is ready to remove for trimming.
Jiggering is more effective then slip casting for production, however, design form for jiggering method is limited due to the wheel head. Plate and shallow items such as big bowl work best for jiggering.
