Can't tell the true from the false? These scientific instruments help you solve the problem

Abstract: many antique lovers are also afraid to buy fakes, so they take them to various industry experts for identification. However, the result is that "different people see different things, and the wise see different ideas". In combination with this situation, it is difficult to make an accurate judgment on highly imitated fakes only by experience, and it is necessary to combine relevant instruments and equipment to make a more scientific and reliable identification of authenticity

antique counterfeiting has always existed. Many antique lovers are also afraid to buy fakes and take them to various industry experts for identification. However, the result is that "different people have different opinions". In combination with this situation, it is difficult to make an accurate judgment on high imitation fakes only by experience. It is also necessary to combine relevant instruments and equipment to make a more scientific and reliable identification of authenticity

the prevalence of "counterfeiting" in the antique market

antiques are antiques and cultural relics. They have always been regarded as the witnesses of bright civilization and historical epitome in the workshop of the first high-level new material entrepreneurship platform "Jinmin we work" (hereinafter referred to as "Jinmin") in China. Through the ups and downs of countless dynasties, the trend of Tibetan and antique is still strong. However, with the continuous progress of science and technology, counterfeiting technology is becoming more and more advanced, The prevalence of "counterfeiting" in the antique market makes many antique lovers afraid to step into it

in the popular "people's name" some time ago, the dialogue between anti-corruption director houliangping and corrupt official zhaodehan triggered people's thinking. Houliangping asked zhaodehan, "do you say you have so much money and don't get any antique works of art?"? Zhaodehan's answer made people laugh and laugh, but it also made people think deeply, "some people have sent me works of art, but let me put an end to it. Now there are too many fake works of art. You say I am so busy, how can I have time to identify". It can be seen that the fraud in the antique market is becoming more and more serious, which has seriously hindered the healthy development of China's art market

it is understood that more than 95% of the antiques in the antiques market are fakes, and the trend of cultural relics counterfeiting is getting deeper and deeper, especially in the Beijing Tianjin antiques market. Even many auction industries are mixed with a large number of fakes. In the face of such rampant "counterfeiting", we must carry out special actions to crack down on cultural relics crimes, severely rectify the "unhealthy tendencies" in the antique market, and prevent and control cultural relics crimes to the greatest extent

counterfeiting technology is amazing

with the continuous progress of China's science, technology and process, the level of counterfeiting is getting higher and higher. Especially with the prosperity of the counterfeiting industry, the division of labor of counterfeiters is continuously refined. The whole counterfeiting market has changed from individual counterfeiting to group counterfeiting before UV curing. A complete industrialization chain has been formed from production to shipment. Many profiteering speculators even do not hesitate to destroy the original ancient furniture and copy one or more pieces as they are, falsely claiming that they are old things repaired and sold at the price of old things

as for porcelain counterfeiting, generally porcelain counterfeiting is completed in two steps: the first step is to make porcelain according to the ancient appearance; The second step is to make it old to express its' ancient 'rhyme. In order to avoid the appraisers using thermoluminescence Technology (the absolute year of the cultural relics can be determined by observing the different thermoluminescence spectra of the objects under the action of rays.) After identifying the authenticity, the counterfeiter used X-rays to crack the high-tech identification means

it is surprising that experts are unable to prevent counterfeits such as automobile manufacturing, electrical products, locomotive and rolling stock, aviation, precision instruments, food cans and paintings. Modern printing methods such as Phototypesetting and copying, slide projection, ink engraving and watermark are widely used by counterfeiters. Some printed paintings and calligraphy can hardly see the traces of ink, which is very realistic. In order to create an age-old effect, some counterfeiters even raise insects and mice to hiss at new paintings and calligraphy. The purpose is to hide people's eyes and ears with "eating traces". This kind of counterfeiting technology is enough to achieve the realm of confusing the false with the true, which is really an eye opener. However, just as the saying goes, the devil is one foot higher, more and more scientific detection technologies and instruments have begun to be widely used

scientific testing instruments have made great achievements

facing the prevailing trend in the antique market, many scientific research institutes and enterprises have begun to develop advanced testing technologies and instruments and equipment. Among them, Shanghai Institute of silicate, Chinese Academy of Sciences is the earliest institution in China to carry out scientific and technological methods to identify ancient ceramics. In order to avoid detection defects on antiques, the institute adopts synchrotron radiation X-ray fluorescence, proton excited X-ray fluorescence Conventional X-ray fluorescence analysis technology is used for nondestructive research and in-situ nondestructive measurement of elements; The Institute of high energy physics of the Chinese Academy of Sciences has also made significant progress in nondestructive testing technology. The institute uses the ultraviolet lamp fluorescence instrument to detect whether there are cracks and repair traces, Raman spectrum to detect the historical age traces of ceramic glaze, X-ray fluorescence spectrum to detect the composition of ancient ceramic glaze... While testing, it also avoids damage to cultural relics

edx8900 spectrum analyzer

in addition, instrument products developed by some enterprises also provide help for antique identification. The edx8900 spectrum analyzer developed by Shanghai Jingpu Technology Co., Ltd. is a necessary scientific detection instrument for the detection of ancient relics. The instrument adopts X-ray fluorescence energy spectrum analysis technology, which can quickly measure the content of elements in various samples and obtain satisfactory analysis results in only 100 seconds

edx800l archaeological detection X-ray spectrometer

the edx800l archaeological detection X-ray spectrometer developed by Tianrui instrument uses the standard ceramic slice samples provided by the Chinese History Museum and the Shanghai Institute of silicate as the instrument calibration standard samples, which can simultaneously analyze the contents of Na2O, MgO, Al2O3, Zr, Ba and other chemical components in the ancient ceramic sample body and glaze at one time, In addition, in order to meet the testing of ceramic samples of different sizes and shapes, the company has specially made a super large vacuum sample chamber

wifi wireless microscope

the WiFi wireless microscope developed by Beijing Xinda Zhiheng Trading Co., Ltd. can magnify antiques and jewelry by 10x, 300X and 600X. It is simple to operate and convenient to carry at a speed ≥ 0.05%fs/s. It can be widely used in various fields, such as document identification, jewelry identification, cultural and antique identification and repair

detection technology still needs to be improved

although up to now, various detection instruments and technologies for jewelry, ceramics, calligraphy and painting have been continuously developed, the technology of market counterfeiting is changing with each passing day, and it is difficult to crack down on the counterfeiting in the market only with the current technology and existing detection instruments

in addition, it is also very important to avoid damage to cultural relics while testing them. Many existing testing technologies are not mature, which will inevitably cause certain damage to cultural relics. Therefore, it is particularly important to develop more high-end and scientific nondestructive testing technology. In this mixed antique market, relying on scientific testing technology can better protect cultural relics and artworks, thus changing the current dilemma of the antique market and promoting the development of China's art market

of course, while improving the testing instruments, the "experience" of some industry experts should not be completely discredited. After all, the testing technology and the use of instruments and equipment can not be 100% correct, and it is one of the traditions of antique collection for collectors to identify the true and false through their own experience and knowledge. In general, it is advisable to take a non exclusive and non superstitious attitude towards various effective identification means. For the identification of antique works of art, we should not only believe in the identification of scientific instruments, but also analyze the authority and scientificity of the identification institution. Only in this way can we make a more scientific judgment on antique collections

it is believed that with the continuous progress of various detection technologies and the continuous rectification of the unhealthy trends in the antique market by relevant departments, the trend of counterfeiting in China's antique market will be improved to a certain extent, and some antique lovers can really collect their favorite treasures
