Ancient jade identification method

In recent years, in the new wave of love jade and Tibetan jade, the number of jade products in the market has increased dramatically, and the coexistence of good and bad, the mud and sand, the fake jade and the fake jade are everywhere. In general, these counterfeit products have such characteristics: 1. In the era of counterfeiting, from the Neolithic period to the Qing Dynasty, they have all seen it. Many of the eye-catchers are imitation of Liangzhu culture, Hongshan culture, Shang Dynasty, Warring States, Han Dynasty, and Qing Dynasty jade. Because of the jade artifacts unearthed in these eras and common products, they are hot spots in the market and easy to be mixed. 2, the shape of the more from the jade catalogue, there are also less data in the real thing, or out of imagination, according to the imitation of the era of general style. 3, most of the craftsmanship is rough and sturdy, but there are also finely carved, technically known as first-class, such as some sub-brand replicas. 4, the texture is more common in Qinghai jade, Russian jade, jade jade, Nanyang jade and other miscellaneous stones, and Hetian jade because of the relatively high price, so the use is less, the surface is often worn, using a variety of techniques to make chicken bone white, mercury False scorpions such as cockroaches, bloody cockroaches, and cow hair ridges. 5. The production sites are concentrated in Anhui, Henan, Zhejiang, and Jiangsu. Other areas also have imitations. For example, the imitation of Hongshan culture in the northeast and the imitation of Qijia culture in the northwest are similar to local jade articles, and the regional characteristics are distinct.

Compared with the eight-thousand-year-old jade river, the antique jade is not very old, but it has a history of more than a thousand years. After the Northern Song Dynasty, with the prosperity of the Golden Stone School, the collection and research of the antiquities was raging, and the ancient jade was also. Driven by economic interests, it also triggered the beginning of counterfeiting and selling. The ancient jade of the Song Dynasty has been quite standard, so that the big collectors can not help but leave the eye. The scale and level of the ancient jade in the Yuan, Ming and Qing Dynasties and the Republic of China were superior to those of the previous generation. How to identify these imitations? I would like to provide some comments:

First, the shape and ornamentation should be unearthed as the standard of identification, and be carefully compared. If there are multiple discrepancies with the contemporary style, it is doubtful. Don’t be lucky, think that you have picked rare treasures, the actual probability is small. Very little. I have met many friends before, and I can understand myself. But I am stubborn and self-righteous. It is not necessarily a good thing for the collection. It often does more harm than good.

Second, work should pay attention to the main features of the past generations, such as the material of the tool, the speed, the knife method, etc., are the basis for the generation. For example, there are no metal tools in the prehistoric period, and there are two holes in the thick hole, sometimes there are spiral marks left behind, and the details are cut by hand. The current imitations use advanced metal tools and mechanical power, so they show signs. Often not consistent. Even if it is deliberately imitated, it always looks like God.

Third, the jade can sometimes be identified by means of mineral identification, such as hardness between 6-6.5, density of about 2.9, can basically be judged to be nephrite, and the general jade distinction, this is the basic material of ancient jade. Most imitations use low-grade jade, such as jade, etc., on the one hand, the cost is low, on the other hand, the hardness is low (below 6 degrees), and the surface is easy to be worn. Excavation often uses chemical methods, such as strong acid to corrode jade, to achieve the natural appearance of the unearthed jade. Generally, fake imitations are fake and eye-catching. They are extremely unnatural and easy to discriminate. However, some masters use modern technology to make them quite chaotic, which is more than the ancient imitations. This reminds the collectors not to use the twilight to determine the authenticity. Twilight is the most easy to imitate, but it is the most discernible. Some friends often listen to the twilight of their collections, and firmly believe that they are authentic, but the discerning person can judge it as a fake only from the shape of the device. Therefore, jade must be considered comprehensively, and only by twilight is bound to "take medicine." In addition, since the imitation of the Ming jade is mostly white jade, it is rarely done, so it is necessary to distinguish between Hetian jade and other similar jade materials, which can be judged by color, luster, etc., such as Qinghai jade, Russian jade color, gray, dark, It is more transparent and has a slightly lower density, while quartz has a high hardness (7 degrees), which is strong and transparent.

Fourth, we need to hold a good attitude, do not deliberately pursue, many things are said to be a "margin" word, can not be met, the identification of the eyes, the machine encountered, good jade to get more chances. I am anxious and eager to do so. I have encountered a lot of money, and no one can enter the country. In addition to the special "confidence" factor, there are also reasons why I can't stand the impulse.

In short, the proliferation of contemporary antique jade (mainly referred to as counterfeit goods) can not be ignored, the correct identification depends on a lot of practice, practice makes perfect, this statement is true.
