High jade identification method

High jade method of identifying high jade appreciation of national cultural relics appraisal committee, Chinese Heritage Society Research Association cloud Jade is such Greek-defined, clear jade formerly known as jade, Chinese jade formerly known as high jade . And nephrite jade with high mainly always pick a thousand miles, has retained most of the Tuan Museum and a few hands in the collectors. Jade is out of the hands of the ancients, reflecting the aspirations of Jiangsu shaped ancient Tibetan culture Communications Limited is identified as one of the antique auction company! Annual collection collections, trade, exchange, and a series of transactions in private auction scheme. Contact: Manager Zhou Tel: 15295031271 QQ: 392439051 E-mail address: 392439051@qq.com jade. Not you, me, his imaginary or theoretical out. Modern antique jade and jade does not have this feature. Jade play is cultural content, the more ancient the better. High quality of its process is relatively complex jade exquisite jade mostly from the Kunlun Mountains, there are many reach Hotan texture. With the collection of high enthusiasm gradually rising jade collectors on how to identify high levels of jade has greatly improved, many goods have become anti-door goods. In particular a material, decoration, shape, process characteristics compared with ordinary high jade breaks, almost in the eyes of the Friends of Tibet has become a regular customer, it can be recognized. This is a private high jade collection of virtuous development of an important symbol, as the situation develops will move to a higher level. Research is a high jade unfathomable knowledge, collectors and counterfeiters always a pair off the right path and depraved interest Shito competitors. The focus of this competition, will focus on performance in high jade crafts, decoration, shape, materials, Seiko, selection of the right. Objectively general goods relatively more, but quality is rare, and the immeasurable value, must compete with each other to become the first choice of headings. But for true and false identification of high quality jade, harder than the average S & P products. The difference is: Poor product is a component of the ancient jade workers manually operated large, leaving tools, machining marks more obvious, and advanced tools faction modern jade is not the far-reaching effects, done in accordance with the ancient methods and modern jade not work would do such a stupid thing that is done to expose the true features are obvious, according to the current level of collectors it can easily be identified. Poor product in the jade there was a marked characteristic, ancient place of miscellaneous materials more choice, there Wada expected, but the overall level is not high on the material. Currently a large number of general goods high jade appear, people of such material and existing patina, impregnation, etc., to form a system which is much concept, there is a sense of familiarity, it is relatively easy to identify. The counterfeit is almost similar to the material to be elected, and to do the old, the effect is always good, it is easy to distinguish. Based on these objective factors, high product imitation jade general who has not dominant. High ancient jade (Han Dynasty before) is drawn, some from the local jade, some from Xinjiang Hotan jade, mostly drawn from the seed bed material or material mountain water, due to the release of these two jade deposits in a long time, under different external environment, it has formed its own skin and Qin jade color. But the ancients thought that the skin and jade Qin will remove all impurities leaving only part of the essence of jade, (Shang Yu left some small animal skins and clever color) high ancient jade mostly with impregnation. Jade is different in different regions, different soil environments, different time and other factors buried Qin jade color is different, and sometimes there will be several impregnation on a jade. Qin jade color resolution can be concluded that the various jade authenticity. We now see the real jade are after impregnation of synthesizer Qinru. High jade Qin color types Levanto, red Qin, cinnabar Qin, Qin soil, water Qin, Qin metals, mercury Qin and so on. Presented by the main colors are red, yellow, black, white, green, purple, blue and transitional colors. The term impregnation is a general concept, in fact, outside of chemical elements should be presented in a Qinru jade color changes and state characteristics. Jade color is different from other pigment qualities outside. Non-interactive forms of state relative independence of color, did not produce the molecular structure of jade interconversion. Interactive state forms within the original elements and foreign elements to produce original jade interconversion, thus changing the nature of changes in the structure of jade, a process that often takes a long time. Research Qin jade color to identify genuine and fake jade plays a vital role. Quality, shape, work, Qin jade is identified four elements. With the development of technology, counterfeiting level is rising, shape, and work has always been man-made, five thousand years ago, the first people in the absence of metal tool conditions can be made out of something that modern people are also doing out, but the real thing. Therefore, research should be focused on the quality and Qin. Quality also has two meanings: one is the texture of jade itself. Jade itself refers to the texture of its mineral properties and origin; the second refers to a qualitative change, and this and Qin inseparable, have Qin in order to have a qualitative change, internal through external work. Jade buried in the ground for thousands of years, will inevitably produce secondary changes. Its manifestations are: crystals, bamboo-like sub-biological, needle-like crystals, ants foot, mildew, chicken white hull, Wormhole like. Jade surface impregnation has its own internal reasons, loose texture, seamless porous jade has a larger surface area than the dense jade, the scientific experiment measured the surface tremolite (genus chain silicate minerals) basic secondary change into talc (which is layered silicate minerals) and stronger than chain silicate minerals are chemically reactive surface, which will accelerate the surface adsorption and surface chemical reactions. Buried in moist acidic soils jade thousands of years, one of their own material active elements (mainly calcium, including mineral impurities remaining calcium calcite and tremolite second generation after talc) will dissolve lose another elements in soils and organic matter will be adsorbed on the surface of jade. Internal surface is increased iron content and reddish brown, should the surface adsorption of iron and generate hematite and goethite caused by the floating talc platelets have a needle, columnar crystals (with 40 times the magnifying glass clearly see), black skin iron than the internal high and the elements that appear often associated with organic matter in the Hongshan jade black hull of detection, detects 30 different chemical elements, which can be concluded that the black epidermis should be humus organic carbon caused (the chemical elements of artificial impregnation often relatively simple). Some jade green surface Qin, which is bronze and jade burial simultaneously formed. Bamboo-like grain and grass land should be oblique dark green jade stone table in the petrochemical revealing slip characteristics. Ants foot and moldy, should appear in the jade surface containing mineral or organic colored jade slit along without Qinru interacts with jade phenomenon. In short, by the Qin jade it is a natural phenomenon, and artificial coloring are essentially different. Experience is a perception, true and false perception, natural impregnation should be produced in the accident. The natural color of this by accident, we found an occasional color composition (which is different from the natural color composition and color composition, because it is human material and spiritual life inseparable in a sense is caused by man) - is this finding is surprising and pleasant. But on the contrary, for artificially colored antique jade piece has a similar color, the aesthetic does not make us have the same wonder and joy, but annoying - because, in our opinion, it is the result of artificial colors and forms design and processing, it should be so, it is taken for granted. Qin - let jade become wonderful, she gives new life to jade, jade to love those who enthralled. It makes history more mysterious and more clearly. High jade in the foreign art market is evergreen. This is so, it is because the high jade got some big European and American collectors in hot pursuit. In fact, it is well understood, because those big collectors have been in love with Neolithic vases, pottery and other ancient collections, and high jade and high ancient ceramics have similar, so by the attention is also logical thing. High jade identification method, breaking the old and new: objects of calcification, impregnation natural transition, and deeply ingrained. (Short false, absolutely not the case) 2, look at the package pulp: Jade in addition to being corrosion, there will be a pack slurry, most importantly, drilling and knife in the package should be consistent with the pulp slurry outside the package, and seamless. Some also have partial oxidation projections exist. 3: When you play the disc, where calcification will slowly change back jade nature, according to the severity of calcification time have long or short; above impregnation will gradually lighter, but it will not disappear. After complete change, Jade will be very moist. Fakes are absolutely the same. 4: The Jade into hot water at 80 degrees, the calcification will continuously fine bubbles emerge from the cracks (because calcification, internal molecular structure has changed, become loose a). No calcification section does not appear this phenomenon. 5: into the water or damaged by water, kneaded with water rubbing feel there is a sticky feeling. And every so until the disc to play transparent. 6: drive to play the artifacts, there will be a gray skin had after seeing sweat or water. (Ash phenomenon) 7: PH value test strips, basic will become neutral. (With the local soil structure is also relevant) 8: Jade has natural cracks, which is due to long-term underground jade by geothermal, ground wet and other effects caused by rifting. That is, we often say "ten jade 9 crack." This is also an obvious feature unearthed jade. 9: Unearthed Jade has yin and yang side, because the affected wetland minerals such as heat, sun surface change relatively nightside small change is calcification, impregnation, corrosion geometric nightside difference. 10: Look reflective, because jade is hand processed, due to the uneven force, there will be many small machined surface of faces, so welcome to see the light, there will not listen to the reflections.
