1 Jade is an important variety of jade. The traditional jade carving products in China have to go through a process called drinking wax after molding, that is, the jade is boiled with wax and then polished. The jadeite processed in this way looks like jadeite and moist. At the same time, this process also has the function of preserving water volatilization and evaporation. However, because this kind of organic wax will also volatilize in nature, the problem of evaporation .. This is also the reason why some water cups should be put on the counter where jade ornaments such as jadeite jade are stored. After a period of time, jade appeared dry, absorbent cotton and cracked. Usually, jade merchants should wax and polish jadeite jade again after a period of time, so as to keep jadeite jade moist before. But once jadeite jade is worn, this wax will be destroyed or volatilized by body fluids and cosmetics. Cracks are exposed. At this time, jade is its true colors. This is why people feel that their jade has changed after wearing it for a period of time. With the passage of time, organic oil and some organic cosmetics secreted by the human body enter the surface cracks of jade. This makes their jade look much warmer. I think this has nothing to do with people raising jade, but the essence is that organic matter has entered the gap of jade. It seems that jade is more moist. I further boldly imagine that people with oily skin secrete more oil. When wearing jade, they may look more moist. On the contrary, people with dry skin wear jade, which has no obvious effect on jade. They just grind off or volatilize the wax on the original jade surface. This may be why people think that healthy people wear jade to improve its quality, while unhealthy people or patients wear jade to darken its luster! I prefer things related to the change of jade and the nature of human skin.

2. The color change of jadeite. As we all know, the green color of jadeite is formed by chromium ions and iron ions in the mineral composition of jadeite. These ions enter jadeite, sodalite, chromite jadeite and some amphibole minerals that constitute jadeite in the form of isomorphism. These ions are the cause of jadeite discoloration. Jade, a pure pyroxene mineral without these chromogenic ions, is colorless. Experimental research shows that jadeite is a kind of low temperature and high pressure mineral. That is to say, the mineral phase cannot be formed or changed at room temperature. Chromium and iron ions entering the jadeite mineral phase are completely or incompletely isomorphic and replaced into the jadeite mineral composition, so these ions do not escape at will. Because the chromogenic ions in these jadeites have not changed, the color cannot change. However, once this mineral phase is destroyed, these chromogenic ions will escape, leading to the discoloration of jadeite.

So I think Master Sa thinks that jade with long color is metaphysics!

3. In the process of making jadeite B, it is generally necessary to go through pickling, alkali etching and glue injection. Pickling is the process of removing iron and manganese oxides from the surface. This is one of the reasons why Master Sa and others can distinguish jadeite A and B from the pictures. Because these yellow, brown and some metallic minerals have been removed, it makes jadeite pure. Alkaline corrosion is the main reason for jadeite discoloration. Because the corrosion of strong alkali destroyed the structure of minerals, some chromonic ions were brought out. This is the essence of the discoloration of B goods. A prerequisite of this process is the existence of fluid, that is, the existence of solution. On the contrary, this kind of fluid does not exist in the wearing process of A jadeite, so the color will not change during the wearing process. The so-called changes are just appearances.

I don't know. Why do you think it is?

After the formation of jadeite, its changes are nothing more than two aspects. The first is the change of planting water. Secondly, it is the change of color. Other changes are also due to these two changes, or have little effect on the changes of jadeite.

Changes of seed water, structural water and partially adsorbed water of jadeite jade. One process of jadeite formation is wax injection. The purpose of waxing is to keep water. It also has the function of bridging wool, so that these defects are not obvious. However, this wax will be partially volatilized or aged in the air, especially under the long-term baking of light. In this way, wool appeared. Emerald looks much uglier. Moreover, the wax will turn yellow, making jadeite even more ugly. Generally, the counter where jade ornaments are placed will put some water containers. Keep the humidity in the counter to slow down waxing. Jade ornaments that are usually not sold will be waxed again after a period of time. There are also some merchants who inject oil into the surface of jadeite, the wax light of cars or the blue beads used in furniture. These are all for one purpose. At the beginning of wearing jade ornaments, this wax will be worn off in a short time or removed for bathing and other reasons. In this way, jade will look uglier in a short time than when it was bought. But with the passage of time, jade will keep in contact with the human body, and the oil secreted by the human body will enter the gap of jade. The constant friction between jade and clothes is equivalent to constantly polishing jade, so that jade will gradually become beautiful. Dare to imagine the oil secreted by people with oily skin.
