Friends who know some basic jade knowledge know that Jade B goods, also known as new jade, are formed by soaking jade raw materials with strong acids or other chemicals. The strong acids here include concentrated hydrochloric acid, concentrated nitric acid and the like. Because strong acid will dissolve the impurities existing between the grains and grains in the jadeite. The jadeite, which has low transparency, many impurities and cracks, gray color and unsightly appearance, becomes bright, clean and transparent. The jadeite soaked with strong acid will destroy its internal structure and become weak and weak, so it will be re-coated with resin.
However, epoxy resin is an organic compound. After a period of time, it will slowly fade to yellow, and it will age and produce many cracks in the turtle, greatly affecting the beauty of the jade. People who are not familiar with jade knowledge may not know that wearing jadeite B goods is harmful to the human body. After long-term wear, it will have a very bad effect on the human body.
