Abstract
The purpose of this research is to find the optimum combustion conditions for the celadon using a gas kiln. It is clearly defined by the amount of CO gas in the kiln that it is fired in the commonly used oxidation and reduction atmosphere. As a result, while celadon was fired at $1250^{\circ}C$, oxidation happened when the amount of CO was 0~4,500 PPM, a neutral condition happened when the of CO was 4,500~25,000PPM and a reducing process was happened when the of CO was more that 25,000PPM. To reduce gas and firing time while keeping uniformly the firing temperature and firing condition of the gas kiln, you can partially block the gas corridor and adjust it as a damper. This adjustment reduces gas consumption by 40% and shortens the firing time by 1 hour.
