1. Precious mud: Daji mutton firewood is made of precious green mud. Mud is characterized by rich mineral components, which makes the kiln gas rich after burning wood. At the same time, it can withstand the high temperature firing of firewood and reduce the defective rate. Because the effect of firewood burning is like jade, and there is a looming effect of Jinsha, it is named Jade Jinsha, which increases the collection value of Dajiyang firewood burning pot.
2. It is difficult to make a fire: firewood combustion requires air humidity and outdoor temperature. It is impossible to burn kiln in rainy and hot days. Different weather will have different effects on the performance of kiln workers, including output and kiln changing effect. The second dragon kiln in Dajiyang is designed obliquely. Due to the air pressure difference caused by the inclination of the kiln body, the Longyan kiln mainly relies on air flowing from the faucet to the dragon tail, so the firing atmosphere of each part in the kiln is obviously different. At the same time, the firewood fired at different positions of the dragon head, the dragon body and the dragon tail is also different, which also makes the works fired at different positions of the dragon kiln behave differently. This is an important part of firewood burning. It takes the kiln's rich experience to better display the works by continuously throwing firewood for three days and nights, adjusting the way of throwing firewood, controlling the temperature and mastering the temperature. The difficulty of burning paper also increases the collection value of Daji mutton firewood cooking pot.
