As a mainstream collection, jade has always been favored by collectors. In the process of collecting ancient jade articles, authenticity identification has always been an important part that cannot be avoided. How to master the identification method of ancient jade is a compulsory subject for every jade collector. The ancients said: There is a specialization in the industry, and there are successive orders, as it is. Today we will talk about the identification of ancient jade. To put it simply, the identification method of ancient jade can be summarized into five words, namely: material, work, shape, grain, and enamel.
"Material" is jade raw material.
In different historical periods, jade materials used in jade have different characteristics of the times. For example, the jade articles used in the Hongshan culture period are mainly made of Xiuyan jade; while the jade articles of the War Dynasty are mostly made of Hetian jade. In fact, since the Shang Dynasty, the jade used in ancient jade articles is mainly based on Hetian jade. The Hetian jade mentioned here refers to Hetian jade, which is produced by China's new strong, and is also known as the “narrowed Hetian jadeâ€.
Compared with the "narrowed Hetian jade", there is also a kind of "generalized Hetian jade", which refers to the jade stone whose mineral composition is mainly tremolite, regardless of the place of origin, and can be called Hetian jade. These include: Russian jade, Qinghai jade, Korean jade and Canadian jade. Although the main mineral components of these "generalized Hetian jade" are mainly tremolite, their jade texture is significantly different from Xinqiang Hetian jade. The most obvious is that its jade quality is not as good as that of Xinqiang and Tianyu.
Most importantly, the history of mining and use of these “generalized Hetian jade†began to appear in the 1980s and 1990s. Therefore, if it can be accurately judged that the raw materials of jade are not new and strong, it is the above-mentioned emerging “generalized Hetian jade, then this jade can fully explain the fact that it is not an antiquities.
It is worth noting that in ancient jade, a considerable part of jade materials belong to “local jadeâ€. The so-called "local jade" refers to jade other than Xinqiang Hetian jade, such as Xiuyan jade, Nanyang jade, Lantian jade and so on. However, there is an important principle in the production of ancient jade, that is, “good materials are well-equippedâ€, that is to say, the exquisite jade of the workmanship, mostly using the new strong Hetian jade material, because its jade quality is outstanding and rare and rare, since ancient times, the ancients have The new strong Hetian jade is called the "true jade". Therefore, at the beginning of the identification of ancient jade, the first judgment can be made from jade raw materials.
"Work" refers to engraving.
The ancient jade identification has always attached importance to the identification method of “micro-markingâ€. Ancient jade is made entirely by manpower tools. There are significant differences between the modern power tools and the traces of ancient human tools. Modern electric tools are characterized by extremely high speeds, so the traces produced when carving jade articles are clearly different from the ancient human tools. The jade crafts of ancient times in different historical periods also have their own characteristics. For example, in the process of making Hongshan culture jade, the application of the scraping process is very popular. Therefore, the surface of Hongshan jade has a unique wrinkle pattern due to scratching; in the Xia, Shang and Zhou Dynasties, the bronze smashing machine became the main ç¢The jade tools, the double-hook method, and the one-slope method are gradually becoming mainstream; during the Warring States period, due to the popularization and application of iron cookware, the jade craftsmanship has advanced by leaps and bounds, and the pattern decoration has become more precise. The openwork and the pupils are handy, and the lines are powerful and powerful. The hole is evenly smooth, and the technique of grazing and surface polishing has reached a very high level. It is no exaggeration to describe it as a mirror.
The different technological characteristics of these different historical periods, with their distinct characteristics of the times, are one of the important means of jade identification. This requires us to make a clear distinction between the traces of jade carving and the characteristics of jade tools in different historical periods through continuous observation and comparison.
Such as shaft, bushing, rotation speed, coaxiality, beating, yaw, electric gyro, non-electrical girders, structural features, differences, and the evolution of the gyro.
Generally speaking, experienced experts are judged from these aspects. Of course, there will be some judgments derived from the actual situation, which will require years of experience.
"Type" refers to the shape.
Ancient jade articles of different historical periods have different styling characteristics, such as the Liangzhu culture jade, the warring States period jade, the Tang Dynasty Yufeitian characters, the Song Dynasty jade belt hook, the Ming Dynasty Zigang brand, the Qing Dynasty Yushanzi, etc., each with its characteristics of the times.
Therefore, we can distinguish the times by the characteristics of the ancient jade.
For example, although the Ming and Qing Dynasties are not far apart, the Ming and Qing Dynasties jade belt hooks have obvious differences in shape. The Ming Dynasty Longshou jade belt hooks have a short width and a slightly square shape. The nose bridge is concave and the eyes are convex. Daiyu with hook dragon head is higher than the Ming Dynasty, the forehead uplift is tumor-like, the mouth is wide and short, the neck curvature is small, and the curve is mostly curved, giving people a sense of fierceness and fierceness.
The jade wares in different historical periods reflect the style and cultural characteristics of different historical periods. Therefore, it is of great practical significance to familiarize with and understand the characteristics of jade wares in different historical periods.
"Stripe" is a fingerprint decoration.
The ornamentation on the jade is rich and varied. The jade ornaments of different historical periods often have great differences in composition, shape and theme. For jade, the ornamentation is an important basis for the replacement of the jade. Although the ornamentation is easy to be counterfeited, it is impossible to distinguish the authenticity of the ornamentation. However, it is necessary to memorize the characteristics of the historical ornamentation. This is called: I don’t know how to decorate, but I can’t do it. Such as the ancient jade on the grain that began to flourish from the Warring States.
The grain pattern refers to a dot with a small tail. It is said to use the image of the grain seed to pray for grain harvest. There are many names of grain, which are called silkworms, and they are also called crepe.
However, the grain patterns in different historical periods have different characteristics. For example, in the early Warring States period, the grain granules were slightly smaller, the mastoids were sharply pointed, and the bottom had prominent "buds", which were not only densely arranged, but also distributed evenly and regularly. In the late Warring States period, the grain lines were mostly yin-yin, and the rounds turned to be fluent, but the hairy marks were more common. The overall feel was smooth and there were no bumps and undulations.
In the Han Dynasty, the grain pattern was inherited from the mid-war style of the Warring States. The grain was mostly hemispherical in the form of a hemisphere, and there was no obvious feeling of thorny hand. In the subtle places, the difficulty of the wheel, often smashing with smashing, on the ground, often see vortex marks. The ornamentation on the ancient jade can reflect the different production period of jade. If a Tang Dynasty ornament appears on a jade with a typical Warring States style, then the authenticity of this jade will be a big question mark. Therefore, through the identification of jade ornamentation, it is an indispensable and important means in the identification of ancient jade.
“æ²â€ means twilight.
Twilight refers to the natural phenomenon that jade is in contact with water, soil and other materials in a specific environment for a long time. Naturally produced water or minerals erode the jade body and change the color of the jade or part of the whole. Twilight is usually an important criterion for the identification of ancient jade. Because jade is a heterogeneous mineral aggregate, it has its own difference in density and hardness. It is also subjected to internal stress during the long geological time, plus the scar saw formed during the artificial tanning process. Traces, as well as some unpredictable cleft palate and aging of the jade itself that existed before the un-adder.
In combination with these factors, the jade is eroded by the penetration of other substances around it, and the appearance of color change or even qualitative change occurs. All the secondary changes in this non-native jade itself are “æ²â€. The traces of discoloration and weathering erosion that we present are called “æ²ç›¸â€.
Although for the jade, the puppet itself is a kind of flaw and defect, but at the same time it is a kind of appearance mark that has experienced the sacred sea and is an important basis for distinguishing the authenticity of the ancient jade. For the twilight, the jargon says: Come understand, go understand. It is understandable that the ancient jade will be shackled, and it will start to break in from the scars, the cracks and the looseness of the jade itself. To understand, it means that there should be a confession between the ochre and the original jade color, and it will not stop at the gutter.
The ochre is divided into a variety of black nicknames, mercury sputum; lime simmered by lime, severely called chicken bone white; colorless with small holes, called bunker sputum; light yellow with small holes It is called a bandit; it has a green ochre called a patina.
The history of Chinese jade is long and long.
In ancient times, jade was both a valuable ritual and a literary genius, reflecting both the level of material life and the pursuit of spiritual life. The profound connotation and unique cultural value of the collection have always attracted the attention of the world. Therefore, the demand for jade articles in the collection industry is also increasing, which has led to the price of ancient jade articles continuing to be firm. Driven by the interests, the current jade market is “making fakes and smashing productsâ€. If you are not careful, you will “eye-catching†and “taking medicineâ€. In order to fully grasp the method of identification of ancient jade, it is not a matter of overnight.
The only way is to start from the objective reality, continue to study and study in depth, and go deep into the market, constantly summarizing practical experience and conducting scientific, objective and comprehensive analysis and identification under the guidance of scientific identification theory. Believe that friends who love ancient jade and traditional culture, as long as they continue to observe more, compare and summarize, through the continuous mastery and integration of the various features of ancient jade, it will certainly become an expert in the identification of ancient jade.
