The Raku technology is a very different firing method from ordinary ceramic firing.According to the introduction on the official website of Raku,they recognize that Amiya comes from Fujian,and Raku technology comes from the South China Tri-color.This paper sorts out the relationship between the South China Tri-color,Zhangzhou Plain Tri-color,Zhangzhou Five-color and Wuxu Chi-painted,and their firing kilns.It is believed that the internal kilns used by Japanese Raku firing have a closer relationship with the"red kilns"used for overglaze baking,and their more direct source should be Zhangzhou Five-color.
