In recent years, the decline in the output of Hetian jade, the prohibition of excavation in some places of production, and the scarcity of high-quality jade materials have made friends who play jade feel "a difficult to find." In recent years, a kind of Hetian jade, which resembles blue and white flowers but is not blue and white, has gradually become "fire". It is - oil storage. Oil storage material origin There are several sayings about the naming of oil depots, which are said to be found in the oil depot, so it is called, and more people tend to be transliterated from Yiriku, which is said to be in Uyghur. It is a material that is not clean enough in a place like a fish pond. To describe the oil storage material in this way, at least from the appearance is relatively appropriate. The oil depot is mainly produced in the ancient river channel of the Gobi Desert in Luopu County, Hetian District. Due to the strong alkalinity of the soil under the Gobi shoal of the ancient river, the cracked surface, the fleshy surface is loose, and the ore of the seed material buried in the soil. The molecules contained in the material components are adsorbed by strong alkali, resulting in the crystallization of Fe3+ and manganese ions in the soil. Therefore, the black skin of the oil depot is mainly distributed in the loose or cracked parts of the meat. Oil storage material characteristics Exterior The oil depot is dominated by cyan and the black skin is mostly distributed along the crack. Some will break into the crack, similar to a black ink line. In addition, some oil storage materials, the skin color is scattered on the surface, and there are also pieces distributed on the surface. This looks a bit like a blue ink and a blue ink. Jade The jade quality of the oil storage material is not the jade fine oily scent of blue and white materials, and the feeling of thick and restrained. Of course, there are individual boutique oil depots that are worth playing. Oil depot and blue and white material Some oil depots look a lot like blue and white, but the ink dots of the oil depot are distributed on the surface, while the blue and white materials are inked into the jade, which is obviously different. The ink color of the oil storage material is basically grown along the cleft, and the ink spots are distributed on the surface of the meat. The color of the blue and white material is broken into the jade. Because of the different amount of graphite, the black and white of the jade is unevenly distributed. The black color of the oil storage material is different. It is a kind of mineral containing iron ions. Sometimes it is black and green, and some are pan-colored rust. The black of the blue and white material is the black of graphite, which is composed of fine ink dots. Although some inks are gray, the graphite content is not uniform, but there is no other color halo. There are also some differences between the oil depot and the black leather. First, its color is relatively thin, and it is relatively scattered, the distribution is irregular, and there is no feeling of polyskin. Secondly, from the perspective of jade, the jade quality of this oil storage material is relatively young. Although the jade quality is relatively delicate, it lacks the feeling of old and cooked.
