Jade identification knowledge

In response to the current lack of knowledge of jade jade articles by many consumers, here are a few concepts related to jade identification:

First, A goods: Jade's raw materials and finished products, all true, no one is working fake, the goods are genuine. High-grade jade has property, value preservation and investment. Not only material wealth, but also spiritual wealth. Because these high-grade jade products are rare and less and less. Many people who do the jade trade have rarely encountered such products. Its price is rising. Some of the finest jadeite products, such as bracelets, saddle rings, necklaces and some jade artworks, can cost hundreds of thousands to millions of dollars or even tens of millions of Hong Kong dollars. Some rich people have reached a level of madness in pursuit of such finished products.

Second, B goods: the bottom of the gray and dirty, water (transparency) is poor, but the green and the color of the middle and lower jade raw materials or finished products, physical and chemical treatment, remove its dirt, increase its water, Make it change the bottom and water, and better set off the original green. This kind of jade that has been processed but not artificially colored is called B goods. The physical and chemical treatment of B goods is to improve the grade of jade, but by processing the structure that has destroyed the jade, it becomes loose, reduces its quality, and changes some of its optical and physical properties. This can't be much lower than the untreated jade.

Third, C goods: the treatment method is the same as the B goods, the difference is that the colorless, green is lighter or greener, and the jadeite finished by the artificial method is called C goods. The difference between B goods and C goods is that B goods only go dirty, increase water without artificial coloring, while C goods sometimes need to be artificially colored in addition to dirty water. The jadeite with good bottom water can be directly colored. (Note: Jade merchants are used to refer to transparency as the head of water. The bottom refers to the cleanliness and transparency of the green part of the jade and the part outside the green.)

Fourth, the color: jade green is the best, purple followed, cyan and red, the worst is black and cat ochre. Green also has advantages and disadvantages, green leaves are better, green is better than light green, green is better than one point, one piece, one piece of green.

5. Hang Hau: It refers to the texture of jade ornaments. Divided into old pits and new pits, the texture of the old pit is translucent and almost transparent. The new pit texture is opaque. It is better to have high transparency.

Sixth, the land: a jade ornaments, no green is called the land. The land is not necessarily white, but also gray, blue, purple, lake green, blue and other colors. Good land, can set off against the green, it seems to add icing on the cake. Inferior land, although there is a very good green, but set off, like a flower inserted in cow dung. Therefore, a good land has lake green, glass color, shrimp color, followed by glutinous rice, white bean land, purple flower land, inferior land with ivory land, hoe land, the worst is black clouds, cats and earth .

Seven, perfection: the extent of innocence. There are no cracks, no plaids in the ornaments, and no impurities are perfect.

Eight, size: the same color, the same pit, the same floor, the same degree of perfect jade ornaments, large value, low value.  

The ABS board, the professional name is acrylonitrile / butadiene / styrene copolymer in English name is the Acrylonitrile-butdiene-styrene.

ABS board is a new material plate industry, is currently the largest output, the most widely used polymer,the products like abs plastic sheet,clear abs plastic sheet,abs sheets for vacuum forming. It will PS board, PP board, SAN board, BS board, the performance of organic unity, both tough hard, excellent mechanical properties of rigid phase equilibrium.
