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.

본 연구는 가스가마를 사용하여 청자를 소성 할 경우 최적의 소성조건을 구하고자 하였다. 특히 환원분위기와 산화 분위기 등의 소성분위기를 가마내의 CO 농도로 명확하게 정의하였다. $1250^{\circ}C$로 청자유약을 소성한 경우, 가마 안의 일산화탄소 양이 0~4,500PPM에서는 산화 4,500~25,000PPM에서는 중성, 25,000PPM 이상에서는 환원분위기가 됨을 관찰 할 수 있었다. 가스 가마 안의 소성분위기와 소성온도를 균일하게 하면서 가스소모량과 소성시간을 줄이기 위해서는 가마 안의 연돌을 일부 막은 후 댐퍼로 조절하면 된다. 이와 같은 조절방법으로 가스량은 40%, 소성시간은 1시간을 절약할 수 있다.
