Fans of ancient jade collections know that ancient jade has a long history and long time to enter the earth. It is in contact with water, soil and other substances in the environment for a long time. Naturally produced water or minerals erode the jade body and make the jade part or whole. The color changes. Because the twilight is from the outside into the jade, the ancient jade with twilight will leave some natural traces on the jade table. To judge the authenticity of an ancient jade, it is necessary to combine the five aspects of material, shape, ornamentation, engraving and ochre. This combination must be a very harmonious combination, and there should be no mutual conflict. That is, all the information is clear to you, this jade should only be a product of an era, not the other. If there is a phenomenon of mutual disobedience, it is "information disorder", and "ancient jade" of "information disorder" must be pseudo-ancient jade. "æ²è‰²": Twilight is often an important feature for identifying the price of ancient jade and its authenticity. It is like the signature certification of ancient jade. Modern people can't use the powerful electric hand tools of mobile power to copy, everything is naturally formed. Due to the different materials contained in the soil in the burial area, the length of burial is different, so the color of the jade is not the same, and the color is ever-changing. In the "Yu Ji" of the Qing Dynasty, Chen Yuanxin made a detailed classification of the jade's twilight. Among them, there is such a record: "It is difficult to deeply test the origins of the various colors, and the total name is the thirteenth color." Twilight classification: Monochrome æ²: To maintain the same color as the essence of jade, that is, the original and secondary colors are the same color. A color other than the color of jade essence is called a monochrome enamel, which is also a color existing opposite to the color of jade. Multi-color enamel: contains two or more colors, usually understood as: rose red is potassium manganese bismuth, red is rust æ², yellow is chrome enamel, green is copper enamel, black is gold (or mercury) æ², white For leeches, etc., the colors produced by the infiltration of various minerals are also combined under the action of mutual matching. The difference between the color of the twilight and the color of the jade: Twilight: In addition to the original color of jade, it is the secondary color; the color of jade, that is, the original color, refers to the color of the jade itself; the transition color is the color produced between the color of jade and the color of tan, also known as Inter-color, intermediate color, can also be illustrated by the brightness of the color. Modifiers of ochre color: such as chicken blood red, sassafras yellow, crab green, parrot green, eggplant purple, black lacquer ancient, fish belly white, etc. are all modifiers, which has nothing to do with the essence of ochre. Since the Song Dynasty, the antique atmosphere has flourished, and the skin and skillful craftsmanship have become more and more in the jade. The modern pseudo-personalists have made full use of this point and added people to the ancient jade color recognition. Many difficulties. However, if we carefully examine it, in addition to the comprehensive processing technology, scoring features, and the shape and decoration factors, we can still find the difference between the color and the color. The former has two kinds of monochromatic and multi-color, which is formed during the jade mineralization. The nature is very stable and there is no trick; the latter is the secondary change after entering the soil, there are tricks, and there are more between the twilight and the original jade. There is a clear transitional dizziness phenomenon. On the prominent point of the carving performance of the object, the original jade sugar part is also related to the theme of the sculpture; while the ochre and sugar mash are naturally formed after the soil is placed, and the distribution is not transferred according to the will of the work, not only at the prominent point. Oh, and the transition phenomenon. Twilight seems to be mysterious, but it is not difficult to forensify, but in the specific identification, it must be as careful as a hair, with certain tools, such as glare, magnifying glass, etc., carefully observe, and combine the jade of ancient jade Comprehensive identification of shapes, patterns, carvings, etc. Travel Blanket,Travel Blanket Pillow,Microfiber Fleece Blanket,Coral Fleece Travel Blankets Huaian Meisiyu Textiles Co.,Ltd , https://www.msytex.com
