Clay as the main raw material，always used to make bricks and tiles through mud treatment, molding, drying and roasting. The production of tile was earlier than that of brick. The production process is also simpler. The requirements for clay bricks are relatively high. You need a clay pugmill to filter out the large impurities in the soil, and then use a double-shaft mixer to mix the mud evenly. If the mud is too dry, you need to add a little water when mixing.
As early as the Western Zhou Dynasty in China, an independent pottery industry had appeared. According to the reported data, China used tiles for construction in the Western Zhou Dynasty three thousand years ago. Bricks also began to be used in construction during the Western Zhou Dynasty.
At that time, people mainly used large-area pottery kiln rooms, which had high firepower and uniform heat. Those rooms also had tight sealing of the kiln, which can make red pottery and harder gray pottery. This pottery-making technology prepared the conditions for the emergence of bricks, tiles, and pottery pipes.
