**Firewood introduction** "Chai burning" is a traditional way of burning kiln. There is a "fire mark" left by the firewood directly in the green body, and the ash that naturally falls after the firewood is burned, so that the color of the work is warm and varied, and it is a realm that the electric kiln and the gas kiln cannot reach. Compared with the general electric kiln and gas kiln, it takes about 8~10 days for the wood to burn from the kiln, the ignition to the kiln, and then the temperature. In addition, the kiln pressure of the wood burning is very large, and the humidity of the climate, the dryness of the wood, the artificial firewood speed, the location of the kiln, etc., may lead to the success or failure of the work, and the damage rate is also high. Old-fashioned wood-burning writers will consider the speed of the entire kiln airflow when arranging the kiln. How to discharge from different sizes of the works, how to estimate how the fire road rises, how to cast firewood, and how to burn the fire mind. Every process must be focused on, so that the perfect wood-burning works are presented. **Precautions** 1. The works are handmade, the textures are not the same, and the computer displays are different. 2. The surface of the work has irregularities, traces of bubbles, glaze, and crack texture. 3. The works are all real shots. If you have any questions, please feel free to contact us. We will reply you as soon as possible!!
