Master Zou Yunyuan's silver pendant lamp can distinguish authenticity by sound. The specific method is to treat the glaze with acidic substances, and then make the knocking sound of new products simple and dull by means. Secondly, from the appearance, Master Zou Yunyuan's floor lamp has clear texture and exquisite workmanship. If the antique building lamp is similar to the ancient building lamp in tire, glaze and firing temperature, its chemical composition is basically the same and its texture can be confused. But careful observation shows that most glazes are bright and dazzling, while those soaked by acidic substances are dim and obscure, lacking the soft and deep feeling of architectural lamps. Some paste "soil rust", but it is not natural. Imitation tire soil elutriation is delicate, the surface of the tire body is smooth and thin, and the feel is light and floating. So as long as we grasp these characteristics, we can see whether the work is the original of Zou Yunyuan. More ways to distinguish the authenticity of the warning can be found in the exhibition star world work number.
