South Red Agate is a kind of agate unique to China. It has been very popular in recent years. Many friends are attracted by Nanhong's charming red and jade-like touch. Some netizens have consulted that their southern red agate has faded. What is the reason? The color of Nanhong is very rich, from Jinhong, persimmon red, rose red to cherry red, blush, red and white, ice and red, etc., each with its own characteristics. Some friends bought the red red agate back. After a while, the color faded and faded. What is the matter? The south red agate is composed of silicon oxide, and the red part is a large amount of iron oxide particles. It is like a cinnabar. If it is not exposed to high temperature, chemical corrosion, etc., the natural south red will not change color. On the contrary, the South Red has been worn for a long time, and the color will become more vivid. When will South Red Agate fade? Nanhong Xishui is a water-based gem. There is a small amount of water molecules between the tiny gaps in the crystals of the material of the South Red Agate. The fine particles of iron oxide promote light and shadow refraction under the illumination with silicon crystals and water molecules, giving people a macroscopic feeling that the color is more vivid. If you can wear Nanhong for a long time, the moisture on the surface of the human skin can penetrate into the South Red, and the oil on the surface of the skin will also be integrated into the South Red, which will block the tiny gaps and make the water not easy to lose. This process is called For "pachet". The longer the time, the thicker the patina layer, the more obvious the phenomenon of light and shadow refraction, and the more vivid the color. And those south red that have been placed for a long time and are not maintained, the water will evaporate with the passage of time, and the phenomenon of light and shadow refraction will become weaker, giving the impression that the color is lighter. However, this phenomenon does not need to worry, just play again to restore the glamorous color. Those who can't play in time and need to be placed for a long time can be cleaned with a layer of non-corrosive oil. In addition, it is very possible to buy fakes, that is, dyed. This kind of wear will definitely fade and it will be harmful to people's health. The dyed southern red agate is very harmful to the human body. The process of dyeing the red agate is to be soaked in a harmful acidic liquid, and then fixed at a high temperature. It is very bad for human skin to wear for a long time. Therefore, when purchasing the investment in South Red Agate, it is necessary to carefully identify the advantages and disadvantages, in order to prevent the purchase of the dyed and processed South Red Agate. When selecting, you can use the cinnabar point in the South Red Agate to identify. In summary, South Red fades, don't panic, after excluding the cause of fakes, it is caused by improper maintenance. As long as you wear it for a long time, you can maintain it. Nanhong can not only restore its original brilliance, but also become more beautiful and moving.
