A Study on Fireing condition analysis of celadon porcelain for reliability manufacturing

The purpose of this study is to identify the best firing condition for Celadon, which is one of the famous traditional pottery to represent Korean culture, by minimizing energy consumption, cutting firing time, shortening the time of processing ceramic making, in order to, save energy as well as to protect the potters' health. Most Korean potter starts their reduction from $950^{\circ}C$ to change kiln atmosphere. However on this study, reduction have started from $950^{\circ}C\;to\;1200^{\circ}C$ by increasing $50^{\circ}C$ at a time. Then the results are analyzed to be compared to previous Celadon, in colors, chroma, and brightness. As a results, it is found, that the best temperature for starting reduction is $1100^{\circ}C$, when chroma and brightness values to meet same with previous celadon. Therefore the best condition could be made by starting the reduction on $1100^{\circ}C$ to fire celadon, which would have shorten 2 hours of firing process and, at the same time, it could have saved the energy by 12%.
