Abstract: A novel apparatus for mixing handcraft materials is disclosed wherein a rotatable container has positioned therein a stationary scraper bar adjacent the inner surface of said container, and an elongated rotatable mixing member substantially in the center of the container, which is rotatable therewith. The mixing member can assume different specific shapes and configurations, but as disclosed herein such member extends from the bottom of the container upwardly in substantially the form of a helix in a first direction around the central axis of rotation of the container for a predetermined distance, at which point the direction of the helix is reversed and the member continues upwardly around said axis in said reversed direction thereof until it terminates near the top of the container. The container is especially adapted to be removably mounted on a potter's wheel for rotation therewith.
