What is Taqing? The so-called Taqing, refers to the county of Heqing. In the industry, Taxian Black Green generally refers to a kind of black sapphire produced in Xinjiang, which belongs to the narrow sense of Hetian jade. Black sapphire, often referred to as black jasper a few years ago, its light-emitting photo is blue-green, and the name of Black-Bei is more upscale, so many merchants will call it this way. However, if you send the test, the certificate will be written in sapphire. So the name of Heibi is not very accurate, and Heiqing is more scientific. Taqing characteristics First of all, its color is not as black as everyone thinks. It is black and blue. In addition, it is oily enough, high density, strong toughness, whether it is visual observation or lighting, tower jade can reach unstructured material, very much. Most of the green materials of the tower green are light green, yellow green, and strong light flashlight, about 1-3mm, mainly due to its high content of "yangshi". Because of its characteristics, the tower green material is also widely believed to be the best material in black and green and sapphire. Mining of tower green material The mining of Heqing in Ta County is different from the mining of Hetian materials, mainly in the riverbed, which is basically mined by large excavators, but Taqing belongs to the mountain material, mainly produced in Pi Li Village, and is in a very remote high mountain area. Therefore, it is extremely difficult for the mining of the tower green material. The most difficult thing is to transport the tower green material. You can only walk on the mountain by hand. The camel pulls across the river. After the furry has been walking for a long distance, it can reach the smooth road and then transport by vehicle. The tower green material itself is not very large, coupled with the difficulty of mining, resulting in a very limited number, so good quality, that is, good tower green material, it is even more rare. At present, Taqing is basically in a state of banned mining. It is expected that it will be basically collected by large households, or mine owners, and the amount of tower green materials that flow into the market will naturally be few and far between. Nowadays, people not only sigh, "good Hetian seed material is difficult to meet, more emotional, good tower Qingshan material, still difficult to find", so in the market, many businesses will also take other materials of black sapphire, take it as The tower green material is told to consumers. Taxi's counterfeit goods 1. Guangxi Black Sapphire: Produced in Guangxi, this black sapphire, some meat is very delicate, the metering can not see the structure, according to the new national standard belongs to the broad Hetian jade. However, the stone is relatively large and the degree of lubrication is poor. It is often used to pretend to be a county. 2, Russian black sapphire: The content of the erectite is very high, the light transmittance is poor, the color is black, the hardness is lower than that of the tower green, and the moisture is not as good as the tower green. 3. Qinghai Black Sapphire: Qinghai black and blue is relatively transparent, the light transmission color is rather boring, and the metering can see the structure. However, the fine first-class Qinghai Black Green is now very rare on the market. Identify the two misunderstandings of Taqing: 1. The transmittance of black and blue in Taxian County will not exceed 3-5mm. This point is actually the biggest misunderstanding, because the depth of light transmission has a great relationship with the content of the actinolite. Any black and green contains the actinolite. The higher the content of the actinolite, the higher the light. The lighter it will be. Therefore, this cannot be used as a criterion for identifying Taqing. Because of Taqing, there are also many materials, can have a very good light; it is precisely because of this, many Yuyou used the price of Taqing to buy Guangxi Heqing, and Russia Black. 2, to distinguish the tower blue with the delicate degree of meat quality: It seems that many people now think that as long as the meat is delicate and the black material of the structure is not seen, it is Taqing, and the material with good meat quality and large structure is not Taqing. In fact, this is wrong. Taqing also has rough materials and large-scale materials. It is not possible to judge the origin of meat by the delicateness of meat quality. If you understand it in plain language, the texture of Hetian jade is that the hardness should be enough, the meat should be tight and dense, the sound should be crisp, the hand should be warm, and the texture should be delicate. And a good tower, must meet these, in order to be considered a fine.
