Firing Shino Carbon Trap Glazes in a Bailey Downdraft Gas Kiln
Bailey Gas Kilns, front loading or shuttle, are ideal for firing Shino Carbon Trap glazes. Because firing carbon trap glazes create excess carbon in the combustion process, Bailey Gas Kilns are designed with a very efficient fume removal system, including collection hoods over the top of the kiln (over lapping the door seams), over the spy ports, over the burner ports, and the chimney exhaust. It is important to have a properly ventilated kiln room when firing Shino Carbon Trap glazes.
Adjustments are made in the Bailey forced air burners to reduce the air to gas ratio early reduction stages to produce free carbon in the chamber. When performing a carbon trap firing, the carbon created by the low air to gas ratio will be sealed into the glaze by the soda in the glaze formula.
