Among the six famous celadon kilns of the Tang Dynasty, Hongzhou Kiln, Yue Kiln, Dingzhou Kiln and the famous white porcelain kiln Xing Kiln could be regarded as relatively well-known kilns in the Tang Dynasty. Among them, Hongzhou Kiln was one of the origins of celadon and had a long history of firing. Yue Kiln had exquisite craftsmanship and the celadon produced was clear and green. It was known as "Secret Color Porcelain" and even became a tribute to the royal family. Dingzhou Kiln produced celadon slightly inferior to Yue Kiln.
