In China, jade has a very long history and unique artistic style. It has always been cherished by people since ancient times. Today's jade market is a fish-eye, a lot of fakes, the quality of the fake technology is staggering, and if you don't pay attention, you will buy the processed "ancient jade." Appreciating jade first needs to know jade, and here I will tell you how to identify and distinguish fake jade.
The color of the ancient jade is divided into two categories, one is the color of the material itself, which is the color of the jade mine; the second type is the color change that occurs after the jade is made. So it is useful to use "bloody" as a fake trick.
Bloody leave
Jewelry and jade experts said: jade has unearthed ancient and ancient times, based on unearthed ancient jade and handed down ancient jade, the difference between the two is expressed in the twilight and luster, the ancient jade "bloody", is due to jade Soft, underground red minerals are caused by jade. The authenticity is old and warm, the fine light is contained, the soil rust and the soil spots are heavier, and the shades and shades have natural color changes. Soil rust is never floating on the surface. "Bloody" is a fake, and the first is a fake jade cortex. The red jade looks like bloody, darker, and lacks shades of color. The second is dyeing, not too deep or too shallow.
"orange peel" fake
The "orange peel" of ancient jade is caused by the action of ground temperature and ground moisture on the surface of jade, also called oxidized protrusion. The side light is most clear when viewed, and the hand touch is not obvious. The fake "orange peel" can be removed by constantly rubbing it with your hand. The "orange peel" of the ancient jade is not to be touched.
"black spot"
Some ancient jade will be affected by minerals in the ground and produce dark spots. "Black spot" is a fake method, usually after wiping the wax. This kind of fake jade with "black spots" is deceptive.
"Chicken bone white" is a fake
"Chicken bone white" is the calcification phenomenon of the loose jade in the ground. “Chicken White†was unearthed in the southern jade, and its scientific name is “lime æ²â€. The means of counterfeiting are to place a barbecue in the fire and to use sulfuric acid to soak. The "white" of the "chicken bone" is the spot formed after corrosion. Because the traces of this kind of production are more obvious, some counterfeiters will be wiped by the hired workers to achieve the effect of chaos.
"fade" fraud
Some of the fake "ancient jade" has a unique bright eye, and there is no vicissitudes or mottles on the unearthed artifacts. The use of special means to remove the "gloss" on the jade, there will be a look that is more old and delicate, deceptive.
"Yangyu" and "dog jade" are fake
The two methods are quite confusing, but the "Yangyu" smells when it is hot with a handkerchief, and it has a slight smell; "dog jade" has a carved look inside, but it has little historical sense.
"cow hair pattern"
The authentic "bovine hairline" ancient jade, some of the texture is concave; and the fake "cow hair" ancient jade has no small depression, but it is a road crack. The texture of the firm is as thin as hair, and the oil is painted. It looks like a "cow-hair" ancient jade.
The ancient jade methods include: smoked, roasted, roasted, boiled, fried, etched, tarnished, etc. The equipment used is kiln, oven, microwave oven, gas stove, electric stove, wood stove, etc. The accessories used are dried apricots and dried plums. Turmeric, grass paper, castor oil, sawdust, shoe polish, asphalt, brown sugar, spices, carrion, various acid and alkali salts and organic dyes, pigments, etc.
