Gas Reduction Firing
|
|||
When a fuel such as gas, oil, or wood is burned, the carbon in the fuel combines with the oxygen in the air to produce the chemical reaction of burning, and the products of this rezction are heat, carbon dioxide, and carbon monoxide.
This carbon monoxide will seize oxygen from any available source, including some of the metallic oxides in the glaze (iron oxide, copper oxide, etc.), greatly affecting the color of the finished glaze.
Among the most famous of reduction glazes are Celedon and Copper Red, also known as Oxblood, Peach Bloom, or Flambe. The old Chinese potters prized these colors for their richness and elusiveness. Having only wood as a fuel source, they developed their magnificent reduction effects because these effects were the natural result of the way they fired their kilns. Reduction firing is impractical for industrial production since it is difficult to control sufficiently for the exact reproduction of colors. It is for this reason it finds favor among potters who place a value on the unique qualities of each piece they make. |
