Hetian jade maintenance:
Avoid collision with hard objectsAlthough the hardness of jade is high, it is easy to crack after being collided. Sometimes, although the naked eye does not see cracks, in fact, the molecular structure inside the jade has been damaged and there is dark cracks, which greatly damages its perfect degree and economic value.Try to avoid dust as much as possibleIf there is dust on the surface of the jade, a soft brush should be cleaned; if dirt or oil stains are attached to the surface of the jade, it should be washed with a warm soapy water and then rinsed with water.Do not use chemical oil removal agents.If it is a very exquisite jade carving, and the dust has not been removed for a long time, you can ask for professional factories and companies that produce jade articles to clean and maintain.
Hotan jade taboo collision
The maintenance of Hetian jade is to avoid collision.Although Hetian Yu's hardness is high, between 6.5 ~ 7 of Mobi, the hardness is higher than the common knife and glass.However, Hetian Yu is easy to crack after collision. Sometimes, although the naked eye does not see cracks, the molecular structure inside Hetian jade may have been destroyed and dark cracks will occur, which will damage the perfectness and economic value of jade.
Xinyu should not contact sweat
Hetian jade should avoid contact with chemical liquid such as perfume.Some people think that the more Hetian Yu is in contact with the human body, the better. In fact, this is a misunderstanding.New jade articles cannot be exposed to too much sweat. If contact, it will damage the outer layer, affecting its original brightness, especially the utensils carved by sheep fat and white jade.If the sheep fat white jade is exposed to sweat too much, it will easily become pale yellow and no longer pure white as fat, so do not put the new jade on the face and nose to apply oil.In addition, Hetian Yu also avoids direct sunlight and baking.
Seed jade and ancient jade appropriately contact sweat is more beneficial.Seed jade and ancient jade have a transformation process, which requires human body temperature help, and sweat will make it more translucent.Because human sweat contains salt, volatile fatty acids, and urea, the surface of the seed jade and ancient jade can be reborn, which is getting more and more moist.
Regularly check hanging ropes to prevent loss
Hetian jade maintenance should be avoided as much as possible. If there is dust on the surface, wipe it with a clean and soft white cloth when wiping, and it is not advisable to use staining cloth and fiber -quality fabric.After a long time, it will have dirt or oil stains that are attached to the surface of jade or carved gaps. You can use a soft brush for cleaning.You can also use warm soapy water to wash, and then rinse with water. Do not use chemical oil removal agents.
Put the Hetian Yupei and the pendant should be placed when it is not used.If it is Hetian jade jewelry, do not put it on the cabinet to avoid the accumulation of dust and dirt affect the transparentness.
In order to prevent Hetian jade from being cut and grinding flowers, Hetian jade jewelry generally does not be equipped with gold and platinum chains. Instead, it is a rope. Therefore, you should pay attention to whether the tie is firm and change the rope every two years to prevent loss.
