Pit Fire Colors

I had problems replying to a comment posted on the "Pit Fire" post so I thought I'd answer it in a regular post. I have found that I get my best colors in the barrel kiln, which I fire completely uncovered until the fire burns itself out. In the pit firing I cover it when I can see the pots through the hot coals. And, it is loosely covered so that it can still get plently of air circulating around the pots. To create colors I sprinkle generous amounts of copper carbonate and miracle grow around the pots. Consistent beautiful colors every time.
