This mug is a glossy white, with a glossy black interior- as dark as your mood when you are in the middle of counting and someone wants to know where their book bag is, or what's for dinner, or any similar question that only you seem to be able to answer. Created in a New Jersey studio from stoneware clay and kiln fired to over 1900 degrees. This mug measures 4 x 4 and holds 16 oz.
