Barrel-Fired Pottery Barrel-fired pottery is a form of wood firing that cures the pots in a fire built in a barrel. Like Raku, it is considered an alternate firing technique, where unusual and colorful pieces of pottery are created at a low temperature. Colors are obtained from the materials burned in the fire with the pottery - various chemicals are added to the fire to produce different colors. With barrel-fired pottery, it is very hard to control the outcome. As the color is added by fuming of materials not attached to the pot, the final pieces are the result of a wide variation of temperature, location in the barrel, and added chemicals. I add salt, baking soda, red iron oxide, and even Miracle-gro to the firing to get a variety of yellows, reds, and oranges. The wood provides the black, but the way it is captured on the pieces depends on how the ashes fall in the firing process. Barrel firing is worth the uncertainty because the results are difficult to obtain in any other technique. The colors appear on the pieces like clouds, producing random fading effects that make every piece unique. I am still trying to figure out where each color comes from. Also like Raku pottery, barrel-fired pieces are not waterproof or food safe. But they make a spectacular artistic statement that more than makes up for their lack of utility. |
