This chalice form went through a soda firing and spent some time on this sales site. Experimenting with sending pieces back through the electric kiln with another Cone 6 glaze I tossed it in, or should I say, I placed it carefully on a kiln shelf inside an electric kiln. It turned out sweet. Porcelain, wheel thrown and slab built. 5 1/2” tall x 5 1/2” in diameter at the bowl.
