Anyone familiar with jade knowledge knows that jade is generally divided into three kinds of goods: A, B, and C: A goods are natural jade, and the constituent elements are relatively fixed, generally harmless to the human body. B goods are jade articles that are chemically bleached and refilled with resin. The resin does not have external force and generally does not have much harm. C goods are poor in color, and will fade after one or two years. Nowadays, the B+C goods are more common in the market, and they are processed by the simultaneous combination of B goods and C goods. After dyeing B+C or C, the acid solution may damage the skin after fading. Some merchants may use the strong acid such as sulfuric acid and hydrochloric acid to imitate the old ochre of jade, and then apply a layer of floor paint on the surface. Crystal paint or epoxy resin. Resin substances together with strong acids may cause irritation. Contact dermatitis may occur after contact with human body, and symptoms such as redness, tingling, itching and peeling may occur. People with sensitive skin are most likely to have these symptoms.
