Without this makeup technique, the jade you get will still be rough, dull and lifeless.

There is a saying: "Carving accounts for three points, while polishing accounts for seven points." This means that for jade finished products, the polishing process is very important. People who know the business know that unpolished jade has poor gloss and transparency. Its true beauty seems to be covered by a veil, rough and rough, like a layer of raw goods.

Rough jade is a semi-finished product of jade. Even if its carving is very fine, it is difficult to stand out because the jade does not have enough gloss and transparency. It is like a person without makeup. Although the appearance is good, the complexion is not rosy and radiant enough, and it is still amazing enough.

After polishing, the rough jade is called mined jade. After mined jade, it becomes translucent and shiny, which is what jade as a precious ornament should look like. We all know that the size and density of the crystal particles inside jade determine the quality of jade. The better the quality, the better the transparency and glossiness of jade. If you want to know whether the quality of a piece of jade is good enough, you only need to look at the image characteristics after polishing.

Therefore, jade polishing is a very important process that cannot be ignored. Jade polishing requires a series of close steps and polishing processes. The operation is not simple, and it is not as easy as unveiling a veil. There are many points that need to be paid attention to.

The first step is to use an oil stone, that is, to use oil-rich rock to polish the jade. Generally, a too large oil stone will not be used, otherwise it will be difficult to control the strength and it will be easy to damage the surface of the jade. What needs to be polished are the rough places where the traces of carving are obvious, and then use oil stones of different coarseness and fineness to polish over and over again.

After being polished with an oil stone, the jadeite must be polished with a grinding wheel. This step is very similar to polishing with an oil stone, except that the grinding wheel has a fast-sliding wheel that rolls back and forth continuously to polish the jadeite more finely.

Some experts will sprinkle some polishing powder in an appropriate amount before these two steps. The purpose is to increase the polishing speed and the smoothness of the jade. Polishing powder is not entirely a bad thing. As long as it is used in appropriate amount and used properly, it can have good effects.

Next, the polisher will take out a drill with an iron nail and sprinkle diamond powder on the drill to polish the carving details. The nails come in different sizes to facilitate polishing of different engraving areas.

After the nails are drilled and ground, they are polished with sandpaper. Polishers have a lot of sandpaper of different coarseness and fineness, which are used to polish those slightly larger carved areas. Generally, the polisher will use two sandpapers of different coarseness and fineness to polish them separately, which is very detailed.

The purpose of polishing is to make the details and surface of the jade smooth. After polishing, there will be a lot of stone chips remaining in the gaps. At this time, you need to use a soft-bristled brush to brush away the stone chips, and then use the brush to dip in stone powder, brush it on the surface of the jade, and then use hard leather (cowhide) to polish it.

The last step is cleaning, the purpose of which is to clean the polishing powder remaining on the polished jade. Ultrasonic machines are mainly used for cleaning, and alcohol is used to wipe areas that cannot be cleaned. At this point, the polishing of the jade is completed, and the next step is a series of processes such as waxing.

On the market, every exquisite jade piece has gone through a series of processes before it can be put on the market. In addition to polishing, jade also has multiple processes such as carving and waxing. Knowing how complicated the jade process is can help you cherish jade more.
