Although jade has high hardness, it is easy to crack after being hit. Sometimes, although cracks can't be seen by naked eyes, the molecular structure inside jadeite has been destroyed and dark cracks have appeared, which greatly damages its perfection and economic value.

Second, try to prevent dust.

If there is dust on the jade surface, clean it with a soft brush; If dirt or oil stains are attached to the jade surface, it should be washed with mild soapy water first, and then washed with clear water. Do not use chemical degreasers. If the jade is beautifully carved and the dust has not been removed for the time being, please ask the professional factories and companies that produce jade to clean and maintain it.

Third, try to prevent contact with perfume.

Seed jade and ancient jade have a transformation process, which needs the help of human body temperature. Sweat will make them more transparent, so seed jade and ancient jade can be exposed to sweat more, because human sweat contains salt, volatile fatty acids and urea, which can make the surfaces of seed jade and ancient jade thoroughly remould themselves and become more and more moist. However, if Xinyu is exposed to too much sweat, it will damage the outer layer and affect its original brightness, especially for objects carved with suet white jade, avoid sweat and oil stains. Many people think that the more Hetian jade touches the human body, the better. Actually, this is a misunderstanding. If you sweat too much, sheep fat white jade will easily turn pale yellow and no longer be as pure white as fat.

Fourth, put away the pendants when they are not in use.

It is best to put it in a jewelry bag or jewelry box to avoid scratching or damage. If it is high-grade Hetian jade jewelry, don't put it on the counter to avoid dust and dirt, which will affect transparency.

Five, Pei Hetian jade pendant should be wiped with a clean, soft white cloth, not with dyed cloth or fibrous hard cloth. Hetian jade jewelry inlaid with diamonds, rubies and emeralds. Only use a clean white cloth to wipe off oil, dust, impurities, moisture or sweat, which will help maintain the original quality.

6. Hetian jade jade environment should be kept at a suitable temperature.

Jade should be kept by a certain humidity. Without temperature and brightness, it will lose its artistic value and economic value.

Let's talk about the care of ancient jade.

Ancient jade, people in the industry and people who play jade have "three taboos" and "four fears". This is the long-term experience and experience of people who play with jade. Liu Datong said in Gu Bian Yu that the so-called "three taboos" refer to the oil, fishy smell and dirty breath of ancient jade, and the so-called "four fears" refer to the ice, fire, Jiang Shui and breath of ancient jade. Although it is experience, it is equally scientific. Friends who like to play with ancient jade can do so in the process.

1 Jade should avoid oil

Avoid oil, that is, ancient jade should avoid contact with greasy. This is because oil can block the fine pores of jade, so that the dust in jade can't escape, and jade naturally won't shine, so it won't show the so-called "clear light". The ancients thought that there was a pipeline to discharge impurities in jade, which was called "earth gate". The so-called "earth gate" refers to the fine hole of jade itself. Because jade is temporarily eroded by water and soil underground, soil or impurities naturally penetrate into micropores. The purpose of conservation is to "spit out" impurities as much as possible, so that ancient jade can be restored. Some people think that putting peanut oil on ancient jade or touching human fat on nose, face value and hair can make ancient jade look shiny and moist, which is actually a taboo. Because as a result, the "earth gate" is blocked, which is harmful to jade.

Once greasy, there are two solutions. One is to boil it in boiling water for a while, and then you can remove the oil. The other is to put jade pieces in prickly heat powder or dry flour to absorb oil. As a result, the "Tumen" was not blocked, but gradually showed a treasure light.

In addition, most jade articles, including ancient jade, are often waxed. Because there is no "soil", Xinyu can "spit out" and block the "soil door", so it is difficult for impurities and dirt to invade, and the luster is better, which is naturally a good thing. Because ancient jade has dirt to vomit, it can't stop the dirt gate, so waxing is not good for jade. Businessmen want to "wax" just to "buy photos". Therefore, the first thing to do when buying ancient jade home is to put it in boiling water to let the wax dissolve out and then wear it.

In daily wear, ancient jade will come into contact with the human body every day, and it will also be contaminated with oil secreted by the human body and the acidity and alkalinity of sweat. People who used to play with jade have two ways to solve this problem. One is "warm vomiting" and the other is "dry vomiting", that is, the jade worn on the body is taken down every four or five months to make it "vomit" greasy and acidic. The so-called "warm vomiting" means soaking jade in hot water of 50-60 degrees before going to bed, and then taking it out and drying it in the morning. The so-called "retching" means putting jade into the itchy powder or noodles just mentioned before to suck out its greasy and acid-base properties. Therefore, the jade "earth door" will not be closed, and the human body will slowly recover under constant temperature and friction.

2 ancient jade taboo

When jade comes into contact with something fishy, it will not only make jade fishy, but also hurt jade. It is found that none of the jade unearthed by the sea is perfect. The ancients believed that this was caused by fishy smell or fishy smell liquid. In fact, because the chemical components contained in fishy smell or fishy smell liquid, such as halogen salts, have a certain corrosive effect on jade, resulting in damage to jade, so ancient jade should avoid contact with fishy smell substances.

3 ancient jade avoids filth

The reason why ancient jade avoids filth is similar to that of oil, that is, filth will block the "dirt gate", so that the lime soil in jade cannot leave the country or even be polluted by it. Therefore, when playing with jade, you should wash your hands in advance.

4 ancient jade is afraid of ice

The so-called "fear of ice" people who used to play with jade thought that if ancient jade was often near ice or frozen, its color would be dead and moist, which was called "dead color". Some people think that freezing ancient jade in the refrigerator will make it "transparent" and "solid". On the contrary, jade may crack and cannot be preserved. What's more, the lute can't "live" but it may not be able to save "live" anyway.

5 ancient jade is afraid of fire

The so-called "fear of fire. If ancient jade is often near fire or heat source, it may make the "color paste" fade. The so-called color paste mainly refers to the appearance luster and transparency of jade. When ancient jade is heated near the fire, especially at high temperature, it will cause cracks and damage the jade, thus losing its luster and reducing its transparency. Don't say it's an ancient jade, even a new jade. In addition, because many jadeites have been "waxed", the wax is easy to melt at high temperature and the surface gloss is reduced. This is why I seldom see a glass of water in the jade counter of a jewelry store. Because the high temperature of spotlights in the cabinet is not good for jade, water can adjust the temperature and humidity in the cabinet, thus reducing the influence of spotlights on jade.

6 Gu Yu is afraid of Jiang Shui.

The so-called "fear of Jiang Shui" Some people think that "Jiang Shui" is a deodorant, which can remove the fishy or rancid smell of unearthed ancient jade. Who knows, but I hurt Yu. The contact between ancient jade and Qin often makes the existing Qin color dim. If it is soaked for too long, it will make jade numb all over. Even if you fight from time to time in the future, it is difficult to remedy.

Grain Rain is afraid of falling.

This is the so-called "fear of shock", which means that when the wearer is frightened or careless, the jade falls to the ground or collides with hard objects, or even "falls to pieces", it will break. Even if the crack is invisible, it doesn't mean it is intact. Because under the violent impact, the internal structure will always be affected, even the tiny cracks invisible to the naked eye are hidden dangers of jade. Therefore, people who play jade pay attention to calmness, caution and dryness, which is also the content of self-cultivation.
