What is the reason why Hetian Yuyue wears more yellow?
Some jade players will find that after Hetian jade has been worn for a long time, it will become more and more yellow. In fact, the color of Hetian Baiyu generally does not change much. The real jade material is relatively stable. Generally, it is normal to wear and play without obvious changes. If there are changes in depth, this is related to the length of wearing and maintenance. There are many reasons why Hetian Baiyu wears more yellow. First, let's talk about the problems on jade. Some jade textures are loose and easy to turn yellow and black. For example, the Russian material in Hetian Yuzhong is like this because it has a rough structure and is worn for a long time. Naturally, it will slowly turn yellow. Therefore, when we choose jade, we choose to buy Xinjiang Hetian seed jade because it is relatively stable in nature and is not susceptible to the external environment. Regarding the oxidation of jade, Hetian jade contains more or less iron. These elements are in contact with air, and the iron ions are oxidized to form iron oxide. The color of jade also exhibits iron oxide. yellow. In particular, the mountain material and the field jade, because they are cut off after mining, they start to contact the air, and the oxidation is faster. Daily improper maintenance of Hetian jade: The true jade nature is relatively stable, and the color generally does not change much. However, the color change of white jade is the most obvious in Hetian jade. Many white jade will turn yellow and black for a long time, which is caused by the wrong maintenance method. The sweat secreted by the human body corrodes the surface of jade, etc. If it is not cleaned for a long time, it will make Hetian Baiyu slowly turn yellow and black, reducing its quality. To prevent this, we need to keep the jade surface clean in time, wash it with water, and brush the dust and grease in the gap. Also note that it is best not to stick Hetian jade on the face or nose, as these parts have the most grease. How to properly maintain Hetian jade? 1, to avoid bumps, jade has fragile characteristics, especially after the engraving of Hetian jade, if it is difficult to repair after being hit by a bumper; even if it is repaired, it is difficult to have a smooth before. It is not necessarily split, but it is a pity that there is a white spot. 2, away from high temperature: long time fire roast and high temperature, will cause jade expansion crack, jade surface gloss and transparency will be reduced. Therefore, high temperatures will cause great damage to jade. 3. Corrosive products with minimal contact. For example, toothpaste, toothpaste can be used in the mouth, why can't it be used in cleaning Hetian jade? Some leathers with low density and oilyness will also erode damage. Also includes perfumes, etc. Chemicals must be kept away. 4, the oil will cover the natural luster of jade, losing its natural mellow beauty. When we selected jade, in order to better observe the gloss of the oil itself, it would wipe off the artificially applied oil. The oil itself has no harm to the jade, and it is not an exaggeration to wipe it off reasonably during the game. Because not all jade is oily, so rubbing oil also has the effect of covering up dryness or cracking. Lazy people do not wear for a long time, you can also rub the oil and put it. 5, cleaning: clean cloth without lint, water, soap, toothbrush, enough. Washing with soapy water and toothbrush can effectively remove surface stains and stains in the gap, and will not damage the jade. Do not bump during the cleaning process, and finally wipe with a clean cloth. When it's not too dirty, it can be like cleaning a spectacle lens. 6. Preservation: Need to be placed, put it in a clean environment after cleaning, put a glass of water in the place where jade is stored. It can effectively ensure the influence of spotlights on jade and ensure the humidity of the storage environment. If it is like some oil-only merchants, it must be cleaned to ensure the natural grease and luster of jade.
