After bisque firing, a copper glaze is applied to the leaf shapes. The pottery is then heated for about 1 1/2 hours to 1800 F in a small gas kiln.
Upon reaching temperature, the lid is removed from the kiln.
The work is removed using a long hadled tongs, and carried to the reduction area.
Sawdust and paper in the hole burst into flame upon contact with the hot pottery.
The flame is quickly smothered by placing a barrel over it . This creates a reduction of oxygen in the chamber which creates interesting colors from the copper glaze.
The finished vessel shows the color changes in the copper glaze. The pink area at the bottom had a shortage of oxygen so the copper in the glaze turned reddish , the area at the top had more air so the copper remained green. The grey black background has been stained by carbon in the smoke.
