I wonder why jade changes color after wearing it for a long time

The mechanism of jade health preservation has been confirmed by modern science. According to chemical analysis, jade contains a variety of trace elements that are beneficial to the human body, such as zinc, magnesium, iron, copper, selenium, chromium, manganese, cobalt, etc., wearing jade can make trace elements be absorbed by the human body, producing a special "photoelectric effect", forming an electromagnetic field and the human body to resonate, so that the physiological functions operate more coordinated.

Due to contact with the air, human sweat, human body secretion of oil and other substances, some substances will slowly enter the inside of the jade, resulting in a change in the color of the jade, which becomes more obvious with the passage of time, and generally slowly becomes warmer.

The reason for the discoloration of the jade for a long time:

1. It is related to the factors of the jade itself.

Jade, like other items, can be both good and bad.

Not all Hetian jade will undergo discoloration, and the jade that is prone to discoloration is generally those with a loose texture. Because the structure of these jades is rough and not delicate, they are prone to slight yellowing after wearing them for a long time. And those Hetian jades with delicate texture, small structure, and warm and smooth will not change much even if they are played for a long time.

2. It is related to the chemical reaction of jade.

As jade, jade contains mineral elements inside, these mineral elements sometimes react with the surrounding environment, jade will contain iron elements more or less, as the wearing time is getting longer and longer, these elements in the process of contact with the air, this iron ion and oxidation occur, the formation of iron oxide, the color of jade will also show the yellow color of iron oxide.

3. It is related to jade maintenance.

A piece of jade needs careful care, the maintenance of jade must be paid attention to, jade in the process of contact with people, by the body secretion of sweat, oil, etc., if not cleaned for a long time, will also make Hetian jade slowly turn yellow and black, reduce its quality.

4. It is related to the environment of contact.

After some people get jade, they do not understand some of the relevant knowledge of jade, which leads to the contact between jade and various things in the environment, and the obvious chemicals in life, such as perfumes, cosmetics and other items containing chemical products, will cause the jade to turn yellow and black when in contact with jade.

5. Dyed counterfeit and shoddy products.

It is also possible that the jade we bought itself is a dyed counterfeit product. Although the color is bright and beautiful when I first buy it, it will slowly fade after wearing it for a long time, showing the most original color. So if you want to buy it, you have to buy jade of better quality.

Because the high temperature generated by daily friction and heating can quickly force out the earthy gas in the jade, making it crystal moist.

Identification of jade: 1. Looking at the sun, there are some cloud-like things in the jade, one by one, the color is clear, like cotton wool.

2. The hardness of jade is very high, like diamond, so it can make marks on the glass.

3. The jade is cold, put a hair on the jade, burn it with a lighter, and the head of the jade will continue to burn. (To be verified, in fact, if the head is burned on glass or porcelain (silicate mixture), heat transfer will occur, and the ignition point will not be reached, so no combustion will occur).

4. Xiaofeng makes a water identification method, drops a drop of water on the jade, such as a dewdrop that does not disperse for a long time; The droplets disappear quickly are counterfeit goods.

5. Tongue licking method, the tip of the tongue licking the real jade has an astringent feeling; Fake jade, on the other hand, has no astringent feeling.
