This tumbler was thrown on the potters wheel of NZ clay.
NZ offers the perfect backdrop for clear soda ash.
The interior was lined with AW2 (1 part blue/4 parts clear).
It was fired for 30+ hours in the wood/soda.
Look how smammered it got on the one side, and how dark with the carbon trapping!
The mug measures over 6 inches tall, 3.5 at its widest, and holds 16oz.
