Antique jade production process

Imitation jade costs were a result of market factors, first of all because of the construction materials, good ingredients and good jobs at good prices. Select the source of the antique samples, basically in accordance with the National Heritage published by publishing color plates, and some unearthed jade devoted to copy a large atlas.

Gemstone suppliers Then there are the illegal dig through the market to buy some of the excavated pits of ancient jade or handed down, according to kind, imitation, clone a number of different regions and different time to sell. To adapt to market changes and needs, while in some areas according to news media reports of stolen ancient tomb, the market also seize the opportunity, in the antique jade unearthed on the shape and pattern to add some contemporary textures, or remove some lines samples to the media stories unearthed jade posing. The basic characteristics of the times this can ensure a clear, detailed process in place, the decorative composition in the spectrum, there are strict age style to be found. Material of different texture of jade artifacts of the standard device corresponding material characteristics, different processing methods of imitation, the market for huge profits were often rely on old methods.

To sell a good price, there are areas classified processing characteristics has been formed, which in addition to their sculpture, but also from other parts of the right to buy their old style of antique jade for rough conditions, after using different methods, eight immortals have done their best on objects to increase the work of the old deal.For the old ways to do old former general is divided into polished, and polished so old. Road not been polished before the rough surface, easy to eat acid or base, do some light gray leather water Qin ideal spot. Eat a light acid or base, then polished, polished, baked goods listed as semi puddle murder, unusual severe. Recognized specifically like to see if the hot ash jade bubble players.

This made the old way, by eating a light in the rough on the acid or base, then work through the fine grinding, but through the drum seal water away from abrasive materials and small steel ball polishing, gemstone wholesalers has consumed a lot of sour taste. Wet soil in another tomb with incised lines on the pH within the support of the local bubble. Therefore, the use of hot water over gray did not taste too much acid out. Such as the old jade, often need to use every day with our ultra-thin films of plastic food wrap and Mongolia, on hold after a long time to open and then heard their point of taste, often can sniff out clues to the chemical for the old.After grinding to do the old, mainly for "keeping the window" and the so-called "Qin-door" method done. General approach is to use diluted hydrofluoric acid solution, to imitate, soaked 4-10 hours, as there are natural differences between the corrosion surface, the middle period to point out brush with oil paint, then put it in strong acid Finally out, that is, the depth of mortar with the so-called skin. If you need to imitate, jewelry supplier in a place other impregnation, the added red, yellow, black and brown and so are several. Are generally prepared by chemical synthesis of the pigment into a liquid when heated to imitate jade, the local paint, depth as required. Jade heating within the body forming pressure, there siphon effect, it can be color Qin Ru yi intramuscular loose areas. After the immersion acid before, a little coarse sand mixed with paraffin wax, will not need to be sealed where gray skin, and then the wax appearance modified so that irregularly shaped samples. This method can separate the role of acid, "leaving the window" look more natural. The "Qin door" also in line with market acceptability.

Some staining and is repeated many times to do the old form, deceptive even more. Cook to imitate jade glass light, is the way packers were polished. That is, to the working procedure complete imitate, the wear layer of chemical paint coat, after drying cloth round polished through drugs, and make it a surface chemical reaction.After grinding to do the old "stay the window" and the so-called "Qin door, after all, through heat and chemical treatment. Gemstone wholesaler So naturally formed with long years bleaching is not the same. Qin made with high temperature in the cooling process, but also should reverse changes in internal pressure, cause some impregnation more concentrated in the surface, appear like block plaque accumulation. The pH did not escape the smell of old is also brought to light. combined with other methods of fire for the old post-synthesis for the old "chicken bone white, "" ox hair pattern "or" old black ", is due to the high temperature fire, there will be fire calamity jade surface marks, careful observation must be able to find. In short, the old man to do nothing less than the high temperature and strong acid and base Qin dye. we need to the authenticity by incised lines judged traces of mill cut is easier to control with or without the acid bite marks such as damage to the original grind Zhuo comparison phenomena, to identify true and false.
