There are a lot of familiar sayings about Hetian jade in the jade industry. For example, "the seed material is produced in Xinjiang" and "the blue and white only seed material" is widely circulated under the word of mouth, but these claims are not It must be correct. Today Xiaobian compiled the top ten rumors about Hetian jade according to the knowledge of Yuyou. If there are any shortcomings, I hope that the friends will correct me.
è°£ä¼ ä¸€: Dyeing / Ershang Hetian jade, no place to identify
Keywords: second, identification, inspection conclusion
When the color of the skin of the sample to be tested may not be controversial, and the clear judgment is indeed two or dyed, the inspection agency shall indicate “the skin is dyedâ€.
Although Hetian jade skin color is true or false, it is reasonable to issue a certificate, but there are still two reasons that make the implementation process extremely difficult: First, the country does not currently have the relevant GB or GB/T identified by Hetian jade dyeing. Judging criteria, there is no effective special detection method (by means of infrared, ultraviolet and other spectroscopy methods of the instrument can only partially identify organic matter dyeing, but for the use of inorganic iron and other dyeing methods that completely mimic the process of jade in the natural world, it is impossible to distinguish Second, there are also rules within the industry: "But when the area of ​​dyeing is small and shallow, it can be omitted." How to grasp the "small" and "shallow" of the dyeing area, this different person may have different understandings, the criteria for judgment are different, and the conclusions are biased and difficult to implement. Therefore, whether the Hetian jade sample sent for inspection is dyed, if the inspection organization does not have absolute certainty, the test conclusion of the dyeing will not easily be troublesome.
In addition, it should be noted that the phrase "the cause of skin color is undetermined", many people understand it, and feel that this is a fake leather. In fact, the "causal cause" is not fixed in the certificate. This is not a "euphemism" of dyeing. It may not be certain, so no conclusion can be drawn.
There are also written "the cause of the skin color is not measured", simply telling you that there is no detection, it does not mean that there is a problem with the skin color.
Summary: It is not impossible to indicate the dyeing or leather color on the Hetian jade inspection certificate, but it is not easy.
è°£ä¼ äºŒ: The seed materials are all produced in Xinjiang.
Keywords: seed material, origin
If the seeds are all produced in Xinjiang, it is a good wish. In fact, the “grain abrasives†from Xiuyan County and the “seed materials†in Luodian, Guizhou have already broken this myth – don’t think that Xiuyan County only produces jade, Luodian only produces mountain materials, and they also produce "Hetian jade seed material", the same Hetian also produces jade jade seed material, which is the phrase "the name does not have the origin"
Summary: The origin of the seed material is not only Xinjiang, but also Liaoning, Russia and so on. Among them, they are different.
è°£ä¼ ä¸‰: Blue and white are all seed materials
Key words: blue and white, mountain material, seed material
“Blue and white are all seed materials†was once widely recognized as “industry misinformationâ€, until the beginning of this century, the Yecheng Mountain blue and white flowers that began to emerge in the market completely broke it.
Yecheng blue and white flower has been turned into "Yecheng black and white material", and some people call it "blue-like". In fact, before this, the end of the mountain, Montenegro had long been produced with mountain blue and white, but the quality of the output was not high and was ignored. Including the recent emergence of Russian blue and white, more life, boring, no aura, difficult to weather.
The distribution law of graphite inclusions alone, such as poly is scattered, is the distribution of clouds or silk, and whether there is "silver sand" to judge the blue-and-white mountain material and seed material is biased, personally think this can only be A supplementary factor, the focus is still to comprehensively check the combination of Ze, jade, graphite and jade.
Summary: Blue and white have both seed and mountain materials, and the quality speaks. If you want to distinguish, you need to make a comprehensive judgment. The "one-push" approach is easy to misjudge.
Rumors four: Russia is more and more dry
Keywords: Russian material, dry
The Russian material itself will not, but the skin is likely to. The skin that may be said here is that the skin that is “driving more and more dry, and getting more and more sturdy†is the layer of “straw skin†(associated stone skin, weathered skin, corrosion layer). Everyone has learned to wipe off the "beauty oil" and "beauty wax" on the jade pieces, and then look good and bad, but the "skin" nature of the Russian material is different from jade, in which the content of SiO2 and FeO is low, while AlO, MgO , K2O, Na2O content is high, oil, wax, etc. can penetrate deeper, wiping and other simple methods are difficult to remove immediately, and with long-term play, oil, wax volatilization or sublimation, it will "dry out" In fact, this is its "original appearance."
Summary: Russia will not be more and more dry, the Russian leather may be.
è°£ä¼ äº”: Qinghai tray will be grayed out after playing or wearing
Key words: Qinghai material, grayed
Once, Yuyou took the block and played some time in Qinghai, saying: It’s really gray! At first glance, I feel very confused. I’m going to take a look, it seems that I didn’t see it when I first saw it. Look, you can find a lot of dirt in the crevice of the engraving. The material is originally water-permeable, and the black matter of the gap emits a faint gray light. After brushing it, it turns white.
I didn’t mean to give thanks to Qinghai’s songs, but I have to say fair words: I often hear about the “legends†of Qinghai’s various “grayâ€, but since the beginning of 1994, Qinghai has been emerging in the market for nearly 20 years. Friends who have played jade have never really seen it, and no one can come up with evidence that Qinghai material has become gray. Qinghai and Hetian materials belong to the same genetic mineralization (the main powder crystal lines are: 3.117 (310), 2.934 (151), 2.698 (151), 1.576 (0.120), which is consistent with the powder crystal line of Hetian), if Hetian materials will not be “greyâ€, and Qinghai materials do not have such qualities. Analysis of the reason that "the disc will be grayed out after playing or wearing" may be related to the "water" of Qinghai material itself revealing other dirty mottle.
Polishing factor. Qinghai is expected to throw a high light, and the disappearance of the thief after playing will also give people the feeling of "depressing, fading, graying."
Psychological factors. Often Yu Yu has played jade for three or two days, saying that it is warm, dry, and small, and these are psychological effects. It is impossible to change so quickly. Qinghai jade is also, always hear everyone say so gray, and then I really feel gray. As for some people say that "the density of Qinghai material is not easy to smear", "the content of quartz in Qinghai is high, so it will become gray", it is all smashing - Qinghai material is similar to Hetian jade in density and tremolite content, and conversely think about it. If the two very simple indicators of "density and impurity content" can distinguish Qinghai materials from Hetian materials, where is the dispute between the origin of the sea, Russia, and South Korea?
Now there is a batch of so-called "Qinghai material new mineral materials" on the market. The identification results are quartz, and calcite and calcium carbonate are also impersonated.
