This tumbler was thrown on the wheel and fired in a gas soda kiln to about cone 3, or ~2100°F.  

It’s decorated with a satin white glaze on the inside, and a dark slip on the exterior. This mug is one of the more successful tests from research I was doing this past summer on lower-temperature soda firings.

Approx. 5.5’’ x 3’’ x 3’’
