"The design of this mug is achieved using the wax-resist glazing technique. The pattern is applied in wax by hand. Then the mug is dipped in glaze and the design reveals itself when the wax is melted during firing. • size: 14 oz. • material content: stoneware. • care instructions: dishwasher & microwave safe. • each wax-resist mug is dipped by hand. After that we let gravity do its thing. There may be slight variations in color, texture and finish to each perfectly imperfect item." DH
