Background

The history of ceramic manufacture in China has been thousands of years, and the inheritance and development of the generations also make the requirements of people on the quality of ceramics higher and higher. The wood is the most main fuel of the kiln, covers the porcelain body when firing the pottery, separates the wood ash from the fire, avoids direct contact with the wood ash, keeps the glaze color appearance of the product consistent, however, under the condition of extremely successful modern porcelain making and firing technologies, a modern pottery creation 'firing appearance' which is completely different from the traditional firewood aesthetic sense is in full play, and the modern firewood firing technology pursues natural combination of the wood ash and the soil. The modern firewood burning is reflected to a great extent in that: the use of a cover when burning the work with firewood means acceptance of "bad" that occurs during the burning process. It is characterized in that ash and flame generated by wood combustion directly flow into the kiln, and different from common beautiful glaze water, the ash falling in the kiln naturally adheres to the body to form warm and smooth natural ash glaze with rich layers under high-temperature baking; the melted or unmelted wood ash, which forms a smooth or rough texture on its surface and various color variations, leaves traces of the fire left standing, natural without a powdery finish, is not repeated and it is difficult to expect its kiln result.

However, the conventional firewood kiln requires 2 to 10 days for burning, for example, Chinese patent CN207730013U, and the burning time of the firewood kiln is very long for experimental research and is not beneficial to use.
