Hetian jade's mountain material is a block of different sizes and angular corners. Most of the seeds of Hetian jade are as smooth, smooth and compact as the cobblestones we saw when we were young, and of course there are large pieces of Hetian jade seeds. The appearance is like scaling a pebbles several times to dozens of times. Now everyone can have a rough impression? The appearance of Hetian jade seed material is the same as that of pebbles. The chemical composition is the same as that of Hetian jade, but the fineness of structure, oil and material is better than the former two. The output is extremely high. Rare, so in the eyes of many jade collectors, the preciousness of Hetian jade seed is unparalleled.
Method / Step:
First, live skin. The real seed material is rubbed and rubbed in the river water for thousands of years, and it is naturally licked. It will break into the color in the soft and soft place and deep into the texture in the place where there is a crack. This skin color is very natural, called live skin. Its color is immersed in the jade, and the transition is natural, and the feeling of skin and meat is the same. The color on the skin should be shallow and deep, and the color on the crack should be from shallow to deep. In fact, good jade is not long skin, that is, there are also a little bit of stars, or in a small crack.
Second, dead skin. The fake skin is pretending to be a seed material, and the second is to cater to the tendency of the love jade to love all kinds of skin color. The method of fake leather is top secret, but it is said to use the dye dyed on the carpet, use the sponge to suck the dye, put the jade inside, and try to infiltrate. Most of the fake skin color raw materials are the same as the metal salt that the seed jade is exposed to in the natural environment, and most of them are jujube red skin. This kind of skin floats on the surface, the color is too bright, there is no transitional natural layering, and it is dry and not moisturized. The parts of the fake skin are in the loose place of jade, called dead skin. This skin color is easy to fade and fade when it is boiled with boiling water.
Third, rolling materials. Rolling materials that pretend to be seed materials are often found on the market. Rolling material is a small piece of mountain material and even Qinghai material, Russian material, and jade material. It is placed in a roller machine and ground in an oval shape, much like a seed material, and then dyed with fake skin. The counterfeiters even turned large chunks of mountain material into small pieces of polished material. The price of the rolling material is not high. Only this point can be concluded that it is not a seed material.
Fourth, sweat pores. Sweat pores are a surrogate here. With or without sweat pores, it is a good way to identify genuine and fake seeds. No matter how delicate, its surface will have numerous tiny pores, much like the pores on the human skin. This surface phenomenon formed in the natural state is by no means artificially forged. It can be clearly seen under a ten-fold magnifying glass. It is very effective to use sweat pores to identify true and false seeds. Because there is a worn-out wear scar on the roll.
