One of the most difficult parts of throwing on the wheel is having to battle centrifugal force.
The pottery wheel has a circular wheel head that rotates while the potter’s hands are pulling and shaping the clay. A potter exerts pressure against the centrifugal force of the clay to create the desired shape. Clay is subjected to centrifugal force (tendency for the clay to fly outwards on the circular path) because a wheel’s centripetal force, center seeking force. Thus the clay’s natural tendency is to fly off the wheel which isn’t uncommon if the clay is not prperlly stuck to the bat.
