Analysis of jade collection of 16 knowledge
At present, there is no instrument for effective testing in the identification of jade, but using the scientific and cultural knowledge we have grasped, using objective scientific theoretical analysis, it is fully capable of effectively identifying the true and false of jade. 1. Jade materials widely used in ancient jade articles include white jade, sapphire, topaz, jasper, and jade jade. At present, there are newly developed stone materials and mineral materials used by a department in proportion to counterfeit goods, or fake yellow topaz with Huang Qiyan. In practice, it is necessary to grasp and distinguish the difference between the authentic jade material and distinguish the old and new differences of a material. 2. Be familiar with the basic structural characteristics of various jade materials, and be aware of the unevenness of hardness and density and the permeable and exudation of jade materials. After grasping the basic characteristics of jade materials, it is possible to analyze the time and right of the ancient jade in the specific environment and premise, the impact on the jade itself, what are the characteristics of oxidative erosion, and grasp the various characteristics of its evolution process. . The fake is not based on the characteristics of the material, nor on the various characteristics of the real thing, but is based on the surface effect of the real product, which violates the laws of natural oxidation and evolution, and is essentially different from the real product. 3, to grasp the aging characteristics of the real jade materials. This phenomenon of aging and aging is re-cut and ground using new materials or old residual materials. The new process surface exposed after forming will produce significant chromatic aberration or damage the original oxide layer. 4. The difference jade material cannot be used as the basis for determining the authenticity of the jade. Since it has been used since ancient times, it is a unified material formed in millions of years. In the identification of falsehood, the identification material can only be used as a single recommendation. According to the evidence, if the material cannot be effectively confirmed, the evidence of the difference between the authenticity and the original should be inherited from other aspects. 5. At present, the counterfeit goods are made of some jade variegated materials with extremely poor quality and extremely low price, or the stone materials are severely forged. After the forming, artificially enhanced erosion is carried out, resulting in the formation of a very thick oxidative corrosion cortex on the surface of the jade. . This cortex easily falls off and there is no clean and moist texture at all. This kind of flower variegated material is not used in ancient jade, but is a kind of stone used by modern deceit. 6, to familiarize with and grasp the jade painting style and performance style of the past, and grasp the structural characteristics of jade style in each era. In the identification of counterfeiting, some jade can be taken from the authenticity and falsehood of the modeling structure, but some high imitation fakes are extremely difficult to identify. In this case, we must search for evidence of difference between true and false from other aspects, because the style of folk jade is extremely eccentric and complex, so we can't determine its authenticity by the style of the instrument, but only as a reference for the determination of sensory effect. . 7. The perfect combination of craftsmanship and art of jade art, ancient jade perfectly reflects the craft effect. However, fakes have significant defects and shortcomings in this respect, either the structural shape is beautiful and the process technology is not able to achieve this effect, or the process design is flawed. 8. We must acknowledge that the degree of mechanization must have a different degree of impact on the quality and scale of the product. Since the ancient times, the jade equipment process and tool materials have been continuously reformed and developed, so different process technologies have been produced in different historical periods. When we grasp the basic characteristics of the real thing, we will be familiar with the differences in the parts of the modern fake goods, and which process technology will produce defects. It is necessary to be familiar with the semi-manual and semi-mechanized way that the processing method of jade has been used since ancient times. In practice, it is necessary to analyze the effect of the process, which is caused by the function of the mechanical equipment itself, and which is caused by the manual manipulation. Differentiate between this and true in this respect. On the other hand, it is necessary to be able to familiarize with some of the technological effects caused by the difference in the level of jade grinding, to understand the intentional manufacturing process error or some technical defects of the fake goods, and to compare the difference between the dead corners of the authentic jade craft. The difference between the materials of modern processing tools and the composition of the abrasive materials and the traditions makes a significant difference in the process grinding of the lines of the lines. This difference is caused by equipment tools and materials, not modern equipment can imitate. The processing and grinding of ancient jade articles mainly adopts the free sand type grinding method, which has significant process difference with the fixed grinding type jade of modern fake goods. It is necessary to grasp the rules of the ancient jade in the process of grinding, and the characteristics of various processing techniques, and compare the procedures and processing methods of which parts of the fake. 9. Understand the counterfeiting methods and techniques of counterfeit goods, and grasp the characteristics of various process effects of fake goods using modern equipment and technology. It is necessary to analyze and grasp the difference between the glass light effect of the authentic jade, and the difference of the general bright jade, and analyze the difference in the technology and material of the light and the principle of causing the difference, thereby distinguishing the difference between the true and false brightness effects. 10. The ancient jade has a phenomenon of clever color and jade with color materials. However, this material has experienced long-term underground environment erosion on the original basis, causing local color material parts to be oxidized and eroded first. The characteristic law. The majority of the oxidized and etched parts of jade are caused by the hardness, density and erosion resistance of a certain part, especially the jade crack caused by internal stress. This state will be first infiltrated or eroded, and it is fake. There are structural differences in the artificial effects of artificial manufacturing. Modern counterfeit goods use the coloring, corner and dirty materials to smear the jade, especially the use of the material itself to smear the oxidized stone. This kind of counterfeiting has become the most important imitation method. In fact, the hardness, density structure and color difference of the parts of such cockroaches being counterfeited are essentially different from those of the real products. It is necessary to identify which are the fake materials of the color materials and natural oxide scales, and which are the real erosion shackles. The true ancient jade will suffer from the phenomenon of hardness change, chromatic aberration change, osmosis and osmosis transition regardless of the oxidative attack, and the phenomenon of significant permeation, hardness change, chromatic aberration and transition produced by the fake man. It is necessary to grasp the characteristic laws of the oxidative erosion of the real thing in a wide range of practice. On this basis, it is necessary to distinguish between the artificial strengthening and the false, and which are the real erosion of the jade. 11. Grasp the main features of the jade jade. The so-called jade jade pointed out that there was no clearing treatment after the soil, the jade itself adhered to various sediments, and the adhesion was extremely strong. The fake goods are made by artificially attached to the jade watch. The adhesive density and cohesive force of the artificial attachment material are very poor. This is an aspect of distinguishing the authenticity. The jade jade should have no trace left by any artificial treatment. . 12, half-life pit jade mainly pointed out that after the soil through the artificial cleaning treatment, this type of jade has lost all kinds of unearthed characteristics of the jade. Under normal circumstances, the dead corners or some of the erosion and damage parts can leave deposits, because some parts of the cleaning will be slightly scratched, and the process edges will produce a little artificial disability. The counterfeit goods that imitate the semi-living jade are mainly used to maintain the sharpness of the edge of the process in the process of manufacturing the surface oxide layer, and the adhesion of the deposited material in the dead zone is very poor. Pay special attention and have the ability to distinguish half-life jade. There is a proportional number of counterfeit goods that currently mimic half-life jade. 13. The semi-cooked jade article pointed out that after a few years or decades of collection, the feel and the degree of penetration did not reach a satisfactory level of maturity. These jade objects have an oxidized texture and a slight abrasion, a slight angular impact, and some dead spots still retain deposits and other various features. This kind of jade must be comprehensively analyzed. The fakes of this kind of jade are mainly made by the ball oscillating equipment and sandblasting equipment to make the surface oxidized texture effect, so that the overall structure and process edges and corners produce a smooth transition. The counterfeiting of such jade is very difficult, and the comparison with the real product will find a lot of loopholes in fakes. 14, cooked pit jade collection is a long-term play to make the process smooth transition edges of jade are proportionate, feel good. In play, the human sweat, acids, bases, and other vegetable waxes exude to the penetration depth of jade, jade making internal reinforcing refractive oil through a sense to deposit the reflective surface translucent jade via long artificial disc refiner will Jade surface scratches different periods overlap, and some will produce damaging scars smooth transition. While fakes do not have such time and premise, they can only be counterfeited by means of enhancing the brightness of the surface. False cooked pit Jade currently has a number of generally poor imitation effect. 15, it is necessary to grasp the fakes were produced by erosion of the various states with hydrofluoric acid, since these fake residual toxic gases and some great, can not be worn or placed in harm to the human body in the room. 16, the collection of jade can not be limited only know the jade, must have the basic ability to identify the authenticity of sculpture, porcelain, painting, bamboo and wood corners, gold and silver bronzes, etc., due to the authenticity of other antiques The law is in harmony with the jade. To discern the first authenticity of the original, only by grasping the essence of the authenticity in practice can we have the ability to recognize the falsity and further study and explore the cultural connotation. Do not take the form of self-blocking collection. Grey Comforter,Velvet Comforter,Twin Bedding Sets,Queen Comforter Sets Hangzhou Dowin Hometextile Co.,Ltd. , https://www.dowinbedding.com
