Abstract: A device for securing a clay workpiece to a pottery wheel includes a base plate and a clay holding member. The base plate includes an alignment feature to at least partially receive a locating feature of the pottery wheel. The clay holding member includes a body extending from the base plate to an upper surface and an opening at the upper surface extending into the body. The clay holding member includes an inner surface defining a tapered shape. The tapered shape is symmetric about an axis of symmetry of the inner surface. The alignment feature is configured to align the axis of symmetry of the inner surface within an axis of rotation of the pottery wheel.
