A preliminary understanding of modern antique jade (2)

Antique jade imitation is ancient jade features. There are many kinds of ancient jade materials, and the different materials form different color changes in ancient jade. Excellent jade (such as Xinjiang Hetian jade) is not etched in almost any natural medium (excluding hydrofluoric acid atmosphere), and remains the original jade color after unearthing, such as the Han Dynasty jade bear (Taiwan version 61). Inferior jade, especially jade with stone components, such as Xinjiang Yuzhong Shibaoyu, Yubaoshi, Xiuyanyu, or other jades, are susceptible to erosion when they contain stones and cracks, and the medium penetrates into them, destroying the surface and the interior. Form a variety of dark colors. Therefore, in addition to imitating the decorative imitation of antique jade, but also imitation of color, in order to artificially make the antique jade also has a "dark color" effect, people in the industry to artificial color known as "for the old."

Good jade is not old, this is a rule that does not follow the rules. One of the reasons is that there is very little good jade in the old jade, and the high price is high in the imitation of work; Second, the good jade is not easy to color, the color of the corrosion is floating, floating on the surface, there is no intention, so the jade is not good . For the old jade is the second jade, there are chapped, impurities in the jade, this jade texture is rough, uneven soft and hard, different shades of altered color, can be deep inside, with the same color effect of ancient jade , so for the old times more jade.

Beijing is one of the earliest areas for old jade. There are a lot of rumours about the old methods. However, because of the confidentiality and little knowledge of the details, here is a brief introduction to the traditional method of making jade from the Beijing Jade Factory.

Since the construction of the Beijing Jade Factory, the white jade, jadeite jade, northeastern jade, and Kuandian jade have been used to distress the old jade. Several masters were veterans of old jade before liberation. After teaching, the method was passed on. The traditional method of making old jade is: After the old product is made, it is usually polished to Wuliang. Put the product in dried plum water and cook for a few days until the impurities, cracks, and grease on the jade are eroded. , or after the occurrence of pitted pitted spots, and then painted on the surface of the product with blood exhaust, yellow, red earth, carbon black, soot, baked by the fire, so that the color immersed inside, wipe clean, and then into the oil, wax pot dip Oil, restore the surface oily luster is imitation jade. If this type of dilapidated jade is buried in the underground for six months or one year, water is often poured and taken out. Some old jade effects played by antiques are also rubbed with wheat stubble, rubbed with skin, and rubbed with skin. Even with a variety of strong acids, including hydrofluoric acid corrosion color. Various methods use different methods depending on the type, texture, color, and hardness of jade.

Plum dried liquid is acidic. During the cooking process, acid etching is the basis. The dyeing is carried out by the acid etching site and the cleavage site. Jade is not subject to acid etching, so it is not easy for good jade to immerse inside. When we used agate color-changing test, we tested various types of jade with acid and alkali. We used organic and inorganic reagents for coloring, and the effects were varied. Similarly, for the old jade can not do without these two basic processes, but the effect is determined by the tester's test procedures and methods.

Antique jade color depends on the method, the effect is different; depending on the type of jade, the effect is different. For the effect of imitation jade, it is important to choose jade that can be corroded, and some simply use various stones for distressed jade, which are cheap and easily colored, which is commonplace in the flea market. I once purchased a distressed jadeite in the flea market. After observing that the jade was corroded by hydrofluoric acid, it was coated with yellowish-red earth to add a small amount of red earth to the yellowish reddish color, or it was colored with a chromium inorganic salt. of.

The identification of old jade and distressed jade is a very important task. Each period of jade or imitation has very strong characteristics of the times and is formed under certain conditions.

If we say that the Shang Dynasty is like jade, then its color is very important in the identification. Ancient jade is natural and infiltrates into the interior; there are always some unnatural shades of imitation, color casts and traces of work, and eating is superficial. The jade of the Warring States Period and the Han Dynasty, apart from difficult to imitate the twilight, its fine craftsmanship and technology are also not easy to imitate. For example, the grain of the valley pattern, the Pugu pattern, the hook line, the rolling mill, and the hollow craftsmanship work are lively and balanced. The decorative beauty and artistic effects presented are hard to imitate. Ancient and modern times, there are not many jade products that can represent the characteristics of the times. There is no good technology to imitate them. Even if there is good technology, due to the differences in the times and the changes in the craftsmanship, the reproductions produced will always be microscopically different. In contrast, the flaws in the reproduction can be found. Once I bought a white jade child in the flea market, I saw that the image and Sui-feng were used goods. I took it home to observe carefully. The method of rolling the child's face was different from that of the old jade, and it was judged to be modern and new. , but it was made using the sand mill production method before the 60's, so there is a jade front and craft characteristics of the old jade.

Distressed jade has two different purposes. One is to like old jade and copy it for the sake of studying its craftsmanship. The Beijing Jade Factory once made this work, specifically looking for imitations of the Qing Dynasty's fine arts, and contrasting the gap between style, craftsmanship, and modernity. Some manufacturers have changed their shapes in the work of digging old jade and restored the rich and honest characteristics of jade. This effort is also effective. Although these distressed jades also have commercial significance, they are not entirely for commercial services. The commercial sector is willing to provide material conditions, supports this work, and obtains economic benefits. It depends on each other to develop. The second is the purely commercial purpose of imitation, fraud, deceitful people, do not hesitate to use fraudulent means to shoddy, fisheyes, violent income, this antique jade is meaningless, but in the flea market, there are many people in the business.

Pure business purposes and research purposes may produce divergent jade of the same purpose, but they adopt two distinctly different attitudes in business operations. One is true or true, and the imitation is imitation, pointing out its essence. It does not hide its shortcomings. The other knows that it is false, and that it is true; knowing that it is time to say good, in order to obtain profits.

In view of the above situation, it is very necessary to study old jade and distressed jade. It is not only for identification but also for evaluation. Qianlong is ancient, degenerate, and develops. It has produced a wealth of jade artifacts and developed a jade model. Modern jade artifacts have been made into antique artworks with fine ethnic flavors. These achievements include the reference to the ancient jade heritage, as well as the modern re-creation. The development of jade should only be achieved through reference, inheritance, and innovation.

In the past decade or so, ancient jade has gradually emerged in the market, and some manufacturers and individuals have turned to produce distressed jade products. The emergence of a large number of distressed jade products in the market exposes many problems, but it does not mean that the distressed jade products cannot be developed, but how to develop, promote, and oppose anything, and how to guide distressed jade products to the formal market. With the passage of time, waves of sand, rough production, and deceive the market in order to make money will inevitably be exposed every day. The distressed jade products left behind will be welcomed for their exquisite craftsmanship and pleasing styling. Like a boutique, it also has eternal value, and it also represents the characteristics of the times. On the other hand, the modern jade devices that have flourished for decades, including inheritance and innovation, have formed the characteristics of the times and placed the photo, exquisiteness, and dexterity in the first place, forming a modern jade style. However, in this process, it ignored the connotation of Yurun and ignored the bold, exaggerated, implicit, and refined artistic style. Looking back at ancient jade, learning ancient jade is necessary and appropriate. At the same time, we should also grasp the direction of antique jade and lose no time in creating it.
