Each piece of Clay In Motion Pottery is handcrafted by the husband and wife team of Bob and Corina Neher. Located in the foothills of the Blue Mountains, their Milton-Freewater studio is where the creativity happens. Bob throws and fires the clay, while Corina decorates and glazes each piece. The Hand Warmer Mug, their most popular product, transfers the heat of your favorite drink right to your hands. Slip your hand into the special pocket and feel the warmth of your coffee or tea. Available in left- or right-handed styles. Dishwasher and microwave safe.
