There was no very successful firewood kiln in the Tang Dynasty, but it was burned in the Five Dynasties and became famous after the Song Dynasty. Ouyang Xiu, a writer in the Northern Song Dynasty, was the first to record firewood kiln documents. He said in "Returning to the Field Collection": "The color of the firewood kiln is like the sky, and it is as clear as the sound, and the world looks at it (rarely). Whoever gets its fragments uses gold ornaments as utensils. ..... whoever looks at the color of the firewood kiln, the sky is blue and the rain is out of date. " Ouyang Xiu was born in Jingde, Song Zhenzong for four years (A.D. 1007), and finally lived in Ning, JaeHee for five years (A.D. 1072). As a consultant (deputy prime minister) in his later years, his description of the glaze and porcelain of the firewood kiln is already a very authoritative statement.

In the Ming Dynasty, Zhang's "The Secret Collection of Qing Dynasty" completely revealed the characteristics of firewood kiln: "When it comes to kiln ware, it is necessary to say that firewood, ru, official, elder brother and ding are indispensable. Wen Qiyun: Blue is like the sky, bright as a mirror, thin as paper, and ringing like a chime. You must see it with your own eyes, so it is true. I saw a remnant in the other direction and made it into a belt ring. The color and light are the same, but the difference is thick. " It shows that Chai Kiln is one of the five famous kilns in Song Dynasty, and its ranking order is Chai, Ru, Guan, Ge and Ding. In addition to the glaze color and glaze sound of the firewood kiln, the content of "as bright as a mirror and as thin as paper" has been added.

In the Ming Dynasty, Cao's On Gegu also said: "Chai kiln, out of the northern land, was burned by Chai Shizong from generation to generation, so it is called Chai kiln, which is blue and moist, delicate, with fine lines and thick loess, which is rare in modern times." The difference between this book and Guitian Collection is that it is the first time to put forward some new ideas, such as "firewood kiln goes out of the north", "firewood kiln is moist and delicate, with fine lines and more coarse loess", and so on. I hope I can help you. Good luck.
