Brick is a block of ceramic material used in building walls. Usually done with brick mortar. The bricks as building material are already known in old. The Romans used the brick and the Roman legions, which were supported by a number of mobile kilns, putting a brick in many parts of the empire. The first descriptions of the production process and techniques used in the manufacture of bricks can be found in the Song Dynasty, a carpenter from Yingzao Fashi in China. Historically, the manufacturing process of bricks look like this. An employee had to make sure the oven temperature was maintained at a level that caused the transformation of the clay to the brightness and color of molten gold and silver. Also had to know when the boiler goes off water to the surface of the enamel. Other workers have less work: mixing clay and water, trampling thick paste, smoothing the surface of the arc, taking them out of the frames, printing of stamps, which indicate that the bricks came from and who is the contractor. The idea of \u200b\u200bsigning the employee's name and date of birth in a brick and where this has been done, is not new in the Ming Dynasty and had no little or even to do with vanity. As early Qin Dynasty (221 BC -206 BC) requires policy-makers and blacksmiths etched their names in the arms to track the quality of the weapons remained the standard required by government.
