The tumbler is made with buff stoneware clay. It's entirely coated in colored glazes which hide the clay color. The exterior was sprayed with a dark tenmoku that fired light. I can't explain that. The kiln fire gods know. The interior was sprayed with a Shino glaze.

The tumbler is 3-7/8 inches tall and 3-5/8 inches in diameter. It weighs 12 oz without packing and holds 13 liquid ozs.
