I made this porcelain chawan specifically to see what the combination of my temmoku with one of my ash glaze variants would do over a heavy texture and here is the answer. The temmoku became a super rich amber style glaze with subtle flowing tendrils running down the surface culminating in big, gravity defying drips on the underside of the bowl. Though a rather heavily saturated iron glaze, my temmoku becomes a translucent deep amber color which the ash glaze seemed to just melt in to though it creates a rich surface environment that shows hints of iridescence here and there especially just under the bowl where the glazes ran and formed drips. The teabowl was glazed overall in the temmoku and then had the inside poured and then was dipped in the ash to just below the transition line in order to keep the entire surface from ending up on the kiln shelves though the bowl was fired on a thin slice of soft brick as a precaution. Though I was hoping for a slightly more ashy effect, I am pleased with the results and think the porcelain, heavy texture and the glaze combination worked quite well together.
