Research Purpose:Research was conducted at China's Guangzhou Province,Foshan's Shiwan Kiln;Henan Province,Yuzhou's Jun Kiln,Japan's Okayama Prefecture's Bizen Kiln;Tokyo University of the Art's Toride Campus' Noburigama and at every kiln,the firing schedule,clay body shrinkage,and other special practicalities were recorded.The dragon kiln at Shiwan was fired for sixteen hours,the small down draft kiln at Jun kiln was also fired for sixteen hours and the Noburigama at Geidai was fired for 74 hours,finally the Bizen kiln was fired for 221 hours.What differences did the firing schedules produce,what effects were given to the clay body? Clay body hardness and coloring,as well as a comparison of the glaze coloring,the length of firing times gave what kind of impression to the piece? The firing time and clay material's practicalities were compared.In addition,through international conferences opened exchanges with Turkey and Ireland,these places' kilns,in regards to their firing methods and schedules,which has brought new insight into this research.In actual firings,Shiwan,Longquan,Jun's downdraft kiln,Geidai's noburigama,and Bizen's anagama,depending on the time and final firing temperature produced clay body hardness,glazing effects,the differences based on the temperature were compared at each kiln's unique firing and researched.
