What is the role of polishing in the process of processing jade into finished products?

When jadeite is transformed into a finished product for sale, the polishing process is very important regardless of the texture and color of the raw material.

As the saying goes, "carving accounts for three points, while polishing accounts for seven points."

What this sentence means is that for finished jade products, the polishing process is very critical. People in the industry know that jade that has not undergone this process will only appear dull and lifeless, so people can only call it "rough goods."

"Raw goods" also means that the product is a semi-finished product. Even if its carving is very fine, it will not be outstanding.

Just like when a person does not sleep well at night, when he wakes up, he cannot see everything around him clearly. No matter how beautiful the objects around him are, they will lose their luster in his eyes.

For unpolished jade, it always has a fuzzy outer film that blocks the beauty of the jade.

Here, I want to mention a term, that is "picking up goods".

This word means that after polishing, the jade looks transparent, bright and shiny as a whole.

The unit of jade is crystal. When the crystals become finer and finer, the gaps between crystals become smaller and smaller, and the crystals become closer and closer together. At this time, the jade will become more transparent.

What determines the crystal state is the quality of jadeite. The better the quality of the jade, the more transparent the jade product will be after polishing.

It can also be said that if you want to know whether the quality of this jade is good enough, you can find out by looking at the image characteristics after polishing.

The above is enough to illustrate the importance of jade polishing.

Jade polishing also requires a series of precise steps. The polishing process is not as simple as polishing your eyes. It is not just about wiping the surface clean.

Next, let's learn with me, what should we pay attention to when polishing?

The first step is to use oil stone to polish the jade.

Jade carvers generally do not use oil stones that are too large, otherwise it will be difficult to control the force and it will easily damage the surface of the jade.

What needs to be polished are the places in the jade where the carving marks are obvious and very rough.

Jade carvers will then use oil stones of different coarseness and fineness to polish it carefully over and over again.

After that, the grinding wheel will be used. This step is very similar to the previous one, and both are designed for grinding.

However, the grinding wheel has a fast-sliding wheel that rolls back and forth continuously, which can grind the jade more finely.

Some experts will sprinkle polishing powder before these two steps, so that they can clearly see which parts of the jade still need to be polished.

So, polishing powder is not entirely a bad thing. In the process of jade polishing, an appropriate amount of polishing powder is also necessary.

Next, the jade carvers will use a drill with an iron nail. This is a specially designed small device.

They would first sprinkle diamond powder on the nails and then process the carved areas. The drill used here is for further polishing of details.

There are many sizes of iron nails, so it is necessary to consider the area of ​​the engraving area and then replace and polish the nails.

After the nails are drilled and ground, it is time to polish them with sandpaper. Jade carvers have a lot of sandpaper of varying coarseness and fineness for polishing those slightly larger carved areas.

Jade carvers usually use two kinds of sandpaper and polish them separately, which is very detailed.

The above steps of polishing are to make the surface and details of the jade smooth.

After polishing, jade chips will remain in many gaps, and a soft brush should be used at this time.

Put some diamond powder on the brush and brush the surface of the jade. After completing this step, the polishing process is almost complete.

The next step is cleaning. The powder left on the jade still needs to be removed through other media. Many people use ultrasound machines.

After using the machine, sometimes we need to patiently wipe the fine parts of the jade with alcohol.

Finally, it’s time to wax. This step is mainly to add a protective film to the jade.

Some people confuse this step with the concepts of glue injection and pickling. Glue injection and acid washing will affect the internal substances of jade, while waxing is only a treatment method based on the surface of jade.

After waxing the jade, you need to blow the wax dry and wait for it to solidify before shaping it. This will help fully protect the jade.

The above are the key steps in jade polishing.

Every jade product on the market has gone through many processes before it can appear in front of us, so we must cherish jade.
