The ancient Silk Road in northern Xinjiang is located on the Gobi Desert in the direction of Altay in the Devil City near Karamay. It is dotted with a fine, warm and colorful stone. This stone is mostly gold and has a radish silk inside, so it is called gold silk jade. Jinsiyu is a kind of quartzite produced in Xinjiang in recent years. The main component is silica, which is a kind of rock widely distributed on the earth. The golden silk jade and the yellow wax stone of Guangdong, the yellow dragon jade of Yunnan is the same kind of jade, all of which belong to quartzite jade, the internal crystal is granular, the particles The size is visible from the naked eye to the invisible. The smaller the particle, the better the transparency. The quartzite hardness is 6.5 to 7. It is said that as early as thousands of years ago, the golden silk jade was the decorative item of the ancient country of Loulan, but because of the inexplicable demise of the ancient country of Loulan and the inaccessible Gobi desert, this beautiful stone was left untouched for thousands of years. Until the 21st century, the occasional opportunity allowed it to reproduce the people's vision, and in just a few years, completed the gorgeous turn from the fine stone to the noble golden silk jade, the price is from a few dollars to the highest Ten thousand yuan per gram! In the jade world, there has been a wave of enthusiasm. The top variety of gemstones in the golden silk jade has become a new target for jade lovers. A stone species (jade species) is highly held, and surely someone will take the opportunity to take advantage of the fake and sell at a low price for profit. With the increasing popularity of Jinsiyu, many fake and shoddy jade have flowed into the gold silk jade market due to the interests. In the various gold silk jade exhibition activities, the Jinsi jade exhibition hall is filled with a large number of inferior fakes. Seriously damaged the beautiful impression of the golden silk jade belt. A lot of impersonating gold silk jade, or shoddy phenomenon is getting worse. Here's a brief analysis of how to identify the real gold jade. To identify the true and false of gold silk jade, we must first understand several treatment methods of gold silk jade, mainly dyeing treatment, filling treatment, wax filling treatment and heat treatment. First, the dyeing treatment of gold silk jade is to soak the gold silk jade in the coloring material, such as colored oil, colored wax, dye, etc., under the condition of normal temperature or heating, the dye is along the gap of the gold jade or the gap of the particles. Infiltrate into the interior of the golden jade to achieve the purpose of improving or changing the color. How to identify whether gold silk jade is dyed, very simple and practical method is to use detergent or toothpaste brush, if the degree of dyeing is high, use alcohol to wipe, remember to wash with water after cleaning. If not, only jade is used to polish, but polishing can only remove the stain on the surface. If the purchased gold jade is processed and dyed, it is usually corroded with acid and can hardly be removed. The dyed falsification is easier to identify. Use a magnifying glass to look at the texture carefully. If the particle gap is covered with a mesh-like distribution, it should be quartz dyed. Dyed gold silk jade bracelet Secondly, the filling treatment of the golden silk jade is for the golden silk jade with obvious granular structure, and the solid material such as polymer is filled into the interior of the golden silk jade along the crack gap of the surface of the golden silk jade or the granular gap of the granular structure in a heated vacuum environment. In order to improve the transparency of the sample, the durability of the golden silk jade can be improved in a short time before the filler is aged, and it is not easily broken during processing. How to identify whether the golden silk jade is naturally not filled, the surface of the natural gold silk jade will have a lot of unevenness and partial gloss difference. However, if the surface structure is rough, it is likely to be pickled. The weaker part is slightly scratched with a knife and has a slight scratch. Because the hardness of the gold jade is higher than that of the knife, if there is a scratch, the composition is not Gold silk jade, but foreign objects, can be preliminarily determined as other symbiotic minerals or fillers. The light transmission observation is white and dull, indicating that the structure has been damaged, and it may be splicing or filling. 3. The waxing treatment of gold silk jade, the surface wax is the last link of the jade carving process, used to improve the gloss of jade. Because of the grainy structure of some samples, the golden silk jade is particularly high in the process of waxing. The heat wax penetrates into the interior of the sample along the particle gap of the granular structure, and the identification method can be referred to the filling process. Fourth, the final heat treatment of gold silk jade means that the yellow gold jade will turn the yellow tone sample into red under the condition of heating and oxidation, because the yellow gold jade will turn into orange-red color after high temperature filling treatment. . The dyed gold silk jade is brighter in color, bright yellow, orange, red, etc., and the color is more common in the form of a wire mesh. Filled and filled gold silk jade has a relatively high transparency, generally translucent to transparent, natural golden silk jade gently tapping will give a crisp sound, filled gold silk jade sound dull, and filled gold wire Jade sound is also relatively crisp and close to natural, so it is more difficult to distinguish. It can be distinguished by means of a magnifying glass to observe its internal features, and there is a large amount of pigment accumulation in the gap of the dyed gold silk jade, which is inert to the natural yellow, red and orange gelled gold silk jade ultraviolet fluorescence reaction. By infrared spectroscopy, the infrared spectrum has strong absorption peaks of organic matter at 2400-2600 and 2800-3200. Glued dyed gold silk jade bracelet In addition, the glass is usually used to pretend to be a golden jade, commonly known as "material." In this respect, the identification is relatively difficult. Generally speaking, the color of the glass is in one go, there is no natural change, and there are bubbles in the glass; its texture is relatively pure, unlike the jade stems of the golden silk jade, there are natural crystals such as cotton and radish. When viewed with a magnifying glass, the pores of the glass are much thicker, and the fractures are bright and shell-like; the hardness of the glass is low, and it is easy to eat the knife. The gold silk jade is high in hardness and does not eat a knife; in addition, the glass frit is attached to the face. Sensitive parts are cooler than gold silk jade. In addition, a sound is dull and a crisp when struck. WUJIANG HUATIAN TEXTILE TRADING CO.,LTD , https://www.huatiantextile.com
