I felt a bit like a kid in a candy store this Friday when I got pots out of three different kiln firings—gas, wood and electric. The main thing I had on my mind were these tokkuri and ochoko (sake flasks and cups). Both flasks were fired in the electric kiln, one is porcelain with white glaze, the other is stoneware with wood ash. I not only sprayed wood ash glaze on the stoneware pot, I dusted raw wood ash powder on top of it, and side-fired it resting on sea shells.
The shino sake cups were fired in the gas kiln in reduction, and the dark area is actually wood ash glaze that I sprayed on top of the shino glaze, not carbon trapping. The other sake cups were wood-fired, and I couldn't be much happier with the results.
