The second time, agate 2000 mesh, jade 3000 mesh fine steel sand, the other 24 hours as above.
The third time, brighten up. The triangular material is taken out by water and put into a polishing bucket. The effect of 3000 mesh luminescent powder is average, and the effect of white corundum is the best. Select the appropriate addition amount. During polishing, do not drain water, put in a proper amount of brightener, and observe the polishing effect 12~48 hours, which shall be subject to the achieved effect, but shall not exceed 48 hours.
If it exceeds the limit, the following phenomena will occur: fine lines in the polished part will be thrown away, and the polished part will crack due to too long polishing time and overheating. The most dangerous thing is that the polished parts will burst and be scrapped. Pay attention to the above, and find experience by adjusting the amount of polishing materials according to each polishing.
Triangular fittings and tripods can be used for a long time without replacement, but that triangle is easy to break. If it is much worse, it must be replaced, otherwise it will be used all the time.

Identify the quality of jadeite original stone;
1 and color
Good color is the first requirement. At present, the most pleasing color is bright green (green tender). Although the top grade color is dark green, it is too dark and makes people feel too dull. Therefore, the top grade dark green is not as high as bright green in price.
Green is the best jade, and the value of red and purple jade is only 1/5 of green jade. If jade contains red, purple, green and white, it is called "Fulu Xi Shou"; If it only contains red, green and white, it is "Fu Lushou". If it is monochrome jade, the color is better. ?
2. Pass
Transparency has a great influence on the value of jadeite. Transparent jade gives people a cool feeling, while opaque jade, no matter how green and tender the color, gives people a dull feeling and lacks vivid aesthetic feeling. Generally, transparent jade is called "glass seed", translucent jade is called "ice seed" or "Guanyin seed", and opaque jade is called "hibiscus seed" or "taro seed".
Transparent and crystal clear as glass, no dirty spots, no chaff and no astringency is the top grade. Translucent and opaque jade are called intermediate jade and ordinary jade respectively. Before and during the Qing Dynasty, jade with red, green and white colors was called jadeite. In modern times, jadeite refers to generally transparent jade. At present, jadeite is mostly transparent and green.
3, even number
The color of jade is uniform. Although it contains white and green, the color is uneven, so the value is very low. The uniformity of color is directly proportional to the numerical value. The price difference between the whole piece of green jade and only some green jade is several figures; The distribution position of color also has a great relationship. A little green in the conspicuous place is naturally better than the green distributed on the edge. ?
4. Form
The shape of jade can be processed into different styles according to different aesthetic requirements, and there is no special standard. Unlike other precious stones, jadeite is valued by weight. The value of jade mainly lies in its shape, size and thickness. The bigger and thicker the jade, the more valuable it is. On the contrary, the price of small and thin jadeite will be worse.
5. According to
When you pick up the jade and look at it in bright light, you can see the color and defects of the jade in an unobstructed view. Sometimes jade that looks perfect on the surface is found to be flawed when photographed.
In addition, you can also see the color distribution through the action of taking pictures, and distinguish whether it is natural color through illumination. At the same time, synthetic jade (fake jade) can't escape the checkpoint of "taking pictures". It's just that the skill of "taking pictures" needs experienced people to be mature enough, and ordinary people may not see why.
