The vitality of blue and white elements has been born from ancient times to the present. The firewood kiln is also an ancient firing technology. Both the official and imperial kilns are fired in firewood kilns. With the development of the times and the advancement of science and technology, the kilns for making porcelain in Jingdezhen are made from firewood. From kilns to mixed firewood and coal, coal kilns, coal-gas tunnel kilns, oil-fired tunnel kilns, and then to liquefied gas kilns, they have undergone earth-shaking changes in a short period of time.

Chai kiln blue and white porcelain is warm in color, rich in layers and heavy in texture. Repeat and it is difficult to predict its firing effect. The firewood kiln blue and white also has its own unique features due to the different firing methods: First, it is scarce. The firing cost of firewood kiln porcelain is high, and the finished product rate is low, so it is very scarce. Each kiln needs to burn nearly 2 carts of pine wood, which is very costly. The second is the degree of moisture. The wood kiln has traditionally used pine wood rich in pine resin. The pine wood volatilized by burning pine wood has a moisturizing effect on ceramics.
