â– rust color Generally speaking, most of the unearthed bronzes have been unearthed, and there are common green rust, red rust, blue rust, and purple embroidery. When you get a piece of bronze, you must first look at it. If the rust color is combined with the body, the depth and depth are consistent, solid and even, radiant and natural, it is naturally generated rust. If the rust color floats above the utensils, it is green and not shiny, the skin is rusted, and it is not moist and glare, it is pseudo rust. â– feel and sound If you are too light or too heavy, you should pay attention. In addition, you can also tap the object with your hand and listen to the sound. If the sound is fine and crisp, you can use it. If the sound is turbid and you make a "beep" sound, you need to be vigilant. â– patterns and models This is a key point in identifying bronzes. The Xia Dynasty bronze pattern is simple; the Shang Dynasty pattern is gorgeous and prosperous, and many times the body is born; the Western Zhou Dynasty is roughly the same as the Shang Dynasty, but the later stage tends to be simple; the pattern of the Spring and Autumn Warring States is fresh and lively; As for the knowledge, it can be distinguished from its font. In the Shang Dynasty, the fonts were regular, and the gestures were generous; the early Zhou Dynasty followed the Boss; the body of the Spring and Autumn Period had fat bodies and lean bodies; the Warring States gold scripts did not pay attention to the gold; the Qin Dynasty unified the text, the general Xiaoyan. â– Bronze and type The identification of copper is relatively simple. Look at the bottom of the bronze. If the texture of the brass is out, it is a fake. If the sole of the foot has been made of copper, brush it with hot alkaline water to see its original appearance. In addition to remembering the type and name of the bronze, it is necessary to know what bronzes were cast and what type of bronze was cast. For example, é’«, é’« is a square, a container, which appeared at the end of the Warring States period; if it works according to the Xia, Shang and Zhou dynasties, it is a fake.
