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.
