This is the smaller mug on the pair, which measures 3 1/2 inches tall by 3 inches in diameter and holds 10 ounces. Larger mug is available separately.
The mug is made from a slab of porcelain which has been laminated with a slice of a colored pattern of clay made by a mokume gane process of texturing then flattening a layered piece of clay, then slicing. All of the color is in the glaze, with a clear glaze. Dishwasher and microwave safe.
