Add a touch of style to your home décor with these beautifully handmade and hand decorated 16oz ceramic mugs by Clay In Motion. Established in 1981, this family owned and operated studio produces more than 100 different items of functional high-fire stoneware and specialty items. Each piece is lead free, dishwasher, oven, and microwave safe. All of the clay used at the studio is of the highest grade giving it a smooth texture and high density, and they prepare and mix all their own glazes in order to control the contents. There are twelve steps in making a quality piece of pottery, the final one being to inspect each piece to ensure the finest handmade quality possible. The use of a coaster is highly recommended; the underside of the mug is unglazed and can potentially scratch smooth surfaces.
