2, the old and exquisite wool fabric will be crystal clear, moist and full after polishing. Look at the feel. Thick and dignified, with strong hand feeling, it is a good material. The higher the structural density, the higher the density of jadeite with less impurities. Compared with jadeite with loose structure and more impurities, it has a stronger hand feeling, but the difference is very subtle, so we should feel it by experience.
3. Polishing can not improve the dimensional accuracy or geometric accuracy of the workpiece, but is a process aimed at obtaining smooth surface or mirror luster, and will not change the original color of jadeite.
4. The purpose of polishing is to polish the surface of jadeite to be fine and smooth, increase the reflection ability of jadeite to light, make it bright and smooth, and reflect the beauty of jadeite material. As for the gap, look at the comparison of jadeite before and after polishing.
5. The effects of polishing and glazing may be different. This is what Mao said. Gambling on water should be polished from different angles, judging the strength of light and structure, and comprehensively judging the performance of water. For beginners, it is better to buy finished products directly.
6. Jade velvet will become thinner after polishing. Because the process of grinding is the process of grinding with a grinder, grinding with a grinder will make the thickness of jadeite wool thinner, but it can't be too thin, otherwise it will lead to the price of jadeite wool, just for the sake of beauty. Therefore, the jadeite wool will become thinner after polishing.
