Firewood kiln porcelain was a famous traditional China porcelain. It was made in the imperial kiln of Chai Rong, the emperor of the Five Dynasties and Ten Kingdoms. It was founded in the first year of Xiande of the Zhou Dynasty (954) after the Five Dynasties. The kiln site may be in Zhengzhou or Kaifeng, Henan Province, but no real objects and kiln sites have been found so far. According to records, Emperor Shizong of the Zhou Dynasty once ordered the imperial kiln porcelain to be "after the rain, the sky is blue and the clouds are broken. This color is for the future." From this, it was inferred that the wood kiln porcelain should be azure glazed porcelain, but in fact, wood kiln also had other colors besides azure. Firewood kiln porcelain had the following characteristics: 1. ** Scarcity **: High firing cost, low yield, and few modern wood kilns. First, the government banned the burning of firewood in the kiln, resulting in insufficient supply of pine firewood. Without special funds and specific purposes, few people would easily use the match kiln. Second, a kiln would burn nearly 2000 catties of pine firewood, which was costly. Third, the kiln required experienced teamwork. The fire and temperature of the kiln were all controlled manually. The pile-handling master needed decades of experience. A slight negligence could cause the kiln to collapse, causing hundreds of thousands of yuan of economic losses. Fourth, the temperature in the kiln was uneven. The front end was high, the back end was low, and the middle was moderate. The quality of the same furnace of porcelain varied greatly, and the rate of finished products was low. 2. ** Moistening degree **: The wood kiln uses pine wood fuel, which is rich in pine resin. The pine resin that is volatile during the burning process has a nourishing effect on the porcelain. The principle of firing was to slowly increase the temperature by constantly adding firewood, so that the utensils in the kiln could be slowly heated. In addition, the water vapor in the furnace and the porcelain glaze could be combined to produce a porcelain body with a unique style of white jade, which made the porcelain glaze subtle and moist. The firing process of the firewood kiln included many processes such as arranging the kiln, filling the pond with the blank, and hanging the kiln. In history, wood-kiln porcelain was very legendary. It had a very high status among China porcelain, and was even considered to be higher than the five famous kilns, Ru, Guan, Jun, Ding, and Ge. Among the six kinds of porcelain recorded in the Xuande Ding Yi Manual found in the Ming Dynasty's palace when sorting out antiques, the firewood kiln was ranked before the five famous kilns of the Song Dynasty and was the more expensive porcelain. However, although there were records of palace collections in history, there were no real objects of wood-kiln porcelain that had been handed down. At present, there was a Northern Song Dynasty Ruyao flower pot in the National Palace Museum in Taiwan that was thought to be a wooden kiln porcelain. The basis was that the inscription "made in the first year of Xiande of the Great Zhou Dynasty" was found under the glaze on the inner and outer walls of the flower pot. The same text could be read with the help of electron microscope instruments, but this conclusion was controversial. In modern times, wood-fired porcelain also referred to porcelain that was fired in a kiln that used pine wood as fuel. In terms of the firing effect, the porcelain fired in the wood kiln was no different from the porcelain fired in other kilns. The novel "Shou Zang" is equally exciting.
