A potter's wheel has a shaft supporting a lower rotatable disc for a pedal and an upper rotatable disc supporting clay to be molded. The shaft connects the two discs. The shaft and discs are supported in a support structure made from a peripheral frame. The support structure supports a top platform through which the shaft supporting the upper rotatable disc passes. The upper rotatable disc is substantially elevated above the top platform to avoid the possibility of an operator's hand being caught and injured between the upper rotatable disc and the top platform.
