Keep these tips in mind and you'll be in a good position when shopping for ancient jade!

1. Identification of porosity. In ancient times, manual drilling, the long holes were mostly drilled in pairs, the holes were medium and fine, the two ends were large, and the hole wall could be seen with spiral patterns of different thicknesses, and the surface was smooth. This is an important method for perforation identification 2, oxidation identification.

There are three phenomena of oxidation: one is the phenomenon of chicken bones with different degrees of calcification; the second is the phenomenon of etching holes and spots; Third, the oxidation is serious into powder. Severe oxidation, usually calcified on the surface of the jade to form white spots, the degree of severity, but naturally covered in the jade part or all of the jade, the degree of light, the surface is still shiny, severe erosion into powder.

3. Slurry identification. Pulp usually refers to a substance formed by other substances attached to the surface of jade in various environments, mainly in three forms: first, soluble mineral condensate in the soil; second, there is grave soil or decaying debris on the surface of the jade; The third is the dirt on the heirlooms.

These substances are subtle and vary in color, and are usually the result of years of physical observation. 4. Identification of color. The identification of Qin color focuses on learning and understanding the color changes between ancient jade and the objects in contact with it in various storage environments for a long time, which we usually call "Qin color", such as ancient jade stored in red lacquerware, which may be affected by red Qin, black lacquer may produce black Qin, and buried in loess may produce yellow-brown Qin.

An important point is: under normal circumstances, the color of the genuine product is relatively simple; The color is darker, and the more chaotic and bright colors are questionable.

1. Don't be fooled by fake jade and fake ancient jade. Now antique markets and stalls are selling fake jade and fake ancient jade everywhere, you must not be deceived. If you don't want to be deceived, you must understand the common sense of ancient jade, such as the hardness, specific gravity, and color of Khotanese jade, Nanyang jade, Xiuyan jade, etc., the characteristics of jade used in each dynasty and each generation, and the shape and ornamentation of jade in each dynasty and each generation.

At the same time, it is necessary to worship the virtuous person who has debuted for many years as a teacher, and ask him to "palm his eyes". You also need to read more books, listen to experts talk about lessons learned, and get started more. If you want to see the real thing, you must go to the provincial and municipal state-run cultural relics shops and museums.

Remember, if you don't have an expert to buy ancient jade, especially at the antique market, you must not easily dig out your wallet, just look at it.

2. Buy a 21x magnifying glass. Use it to see the carving, knife technique and historical traces of ancient jade. No matter how clever a counterfeiter is, he can't even make it to the point where a 21-fold magnifying glass can't see it.

At the same time, the more real the fake, the greater the cost, and it is impossible for him to lose money to fake!

3. Run more markets and pay attention to jade. If you have your own friends in the auction house or cultural relics store, you will be better informed and have a broader vision.

Fourth, we should do more "homework" and practice our eyesight. It is often mixed with real and fake jade, and then the real jade is picked out from it. Of course, this is not something that can be done overnight, but where there is a will, there is a way.

A piece of ancient jade, no matter what.

Whether it is "handed down from generation to generation" or "unearthed ancient", after the baptism of years and the erosion of water and soil, it will inevitably leave a variety of color and imprints, thus providing a reliable basis for identifying ancient jade, which is the color and imprint. This article discusses the types of color, the material basis for the color, and the falsification of the color. The unearthed ancient jade is rich in color, and the main colors are:

Purple and red: including iron and blood; Green Heart: Mainly Tongqin; Huang Qin:

including Tuqin and Rosin Qin; Bai Qin: The ancient jade affected by the earth fire turns white; Qingqin: the same as the indigo on the clothing is caused by penetrating into the texture of the jade; Heiqin:

Ancient jade, which has been affected by mercury, is usually black in varying degrees; Huaqin: It refers to the color of ancient jade due to the joint action of substances that are affected by the color. In addition to the unearthed ancient jade has the color of Qin, the ancient jade also has the characteristics of the color, and the color of the ancient jade is called "pulp" and "cow hair pattern".

This kind of pulp and cow hair pattern are the two major elements of our identification of ancient jade. The counterfeiting of ancient jade includes the color of the unearthed ancient jade, the pulp and cow hair pattern of the ancient jade. The traditional methods of counterfeiting ancient jade are:

falsifying the loess rust law; Knock rust method; forged chicken bone white method; forged dark spot method; forged cow hair pattern method; oil extraction; Mei Yu; Identifying the authenticity of ancient jade artifacts is an important part of jade appreciation, and it is also a very complex and practical task, which requires rich experience, extensive historical and cultural knowledge and professional skills. The identification mainly includes the identification of jade materials and the era of production.

If you don't invite an expert, the first-time jade player should identify the authenticity of the jade by himself, which can be observed from three aspects:

1. Because the texture of the glass is very brittle and hard, the structure is arranged and dredged, and the density and toughness of jade are lacking, and it cannot withstand strong high-speed rotary carving, so it is generally not processed on the glass with high relief and round carving.

Second, use a magnifying glass to find bubbles, even if you can only see one, you can confirm that it is not jade.

3. Chromium oxide is added to the glass, and the color is close to ruby; Cobalt oxide is added, and the color is nearly sapphire; Chromium oxide and copper oxide are added to give the color to the ...... of emeraldsAnd so on, and so on, and there are many kinds of fake jade. However, their tones always appear thin, lacking the oily and rich feeling of natural jade.

Ancient jade is a jade carving from the hands of the ancients and reflects the voice of the ancients. It's not you, me, or him imagining or theorizing. Modern jade carvings and antique jade carvings do not have this feature. Jade plays with cultural content, and the more ancient the better. There are many imitations, long eyes!
