G3948A iron red cone 6 oxidation glaze at its best

This spoon jar is glazed with the G3948A recipe. It was fired using our standard cone 6 C6DHSC slow cool schedule. The body is Plainsman Coffee Clay. The inside glaze is GA6-B. The metallic appearance was achieved because of the thick application. But this glaze has a fluid melt and should have run on to the kiln shelf. Why didn't it do that? Because of the way I glazed it. The inside was done first. Then wax was applied over the rim and down the inside for a couple inches. Then I applied a thin layer of the iron red to the bottom half to act as a catch glaze - by pushing the piece down into the bucket of dipping glaze for only a second. That dried in about 5 seconds enabling flipping it over and pressing it down to do the upper half. I held it down much longer and got a much thicker layer (with a little overlap over the thin section). During firing it all evened out - leaving only a little evidence of this method near the base.
