How to polish jadeite raw stone, six steps of jadeite polishing

Speaking of polishing, everyone should be familiar with it. Many things will be polished, and jade products are also polished. Most of the jade products on the market are polished. Today, let’s learn how jadeite raw stones are peeled and polished to become finished jadeite products. Let’s see what are the steps in peeling and polishing jadeite raw stones.

1. Peeling: Use small hand movements on the angle grinder to remove the skin of the jadeite raw stone. At this time, several deep marks like grooves will be left on the surface of the raw stone. Players do not need to worry too much. Note that this step is very easy to get injured. It is recommended to wear anti-cut gloves, goggles, and anti-noise earplugs; you can also use a hanging grinder or a bench grinder with a hose and a coarse grinding head to peel, but it is very time-consuming; you can also use a gambling stone cutting machine to directly cut off the skin, but it is easy to cut away the green.

2. Digging out dirt: After peeling, there will still be a small amount of impurities on the skin of the jadeite stone deeply embedded in the jade flesh, which must be ground off with grinding heads of various shapes. The standard for digging it out is: you see pure white water dripping and the grinding head feels strenuous.

3. Roughening: In order to remove the skin and dirt, we often use the coarsest grinding head (so that the grinding speed is fast). Next, we need to change to a grinding head of a different grade to carry out the roughening process.

4. Fine grinding: Change to the diamond grinding head (white, finest) and fine-grind the surface of the jadeite raw stone. As water droplets flow through, you can already find that the "precious light" slowly begins to appear on the surface.

5. Rough polishing: Use different grades of oilstones or sandpaper to grind the surface of the jade until you can no longer feel any marks on the surface of the jade with your fingers; or use a bench grinder with different types of grinding wheels for grinding. For uneven places, use a hose and a pointed wool grinding needle, and grind with small-grade diamond powder paste.

6. Fine polishing: Mix the diamond powder into a paste, find a piece of bamboo and dip it in the diamond powder paste and rub it back and forth on the surface of the jade. This requires patience and perseverance. When you feel that the bamboo starts to slip on the jade, you are not far from success. You can also use a hanging grinder or a bench grinder with a hose, a wool wheel and high-grade diamond powder paste to polish a large area, and then use a wool ball and high-grade diamond powder paste to polish the uneven fine parts.
