Changhua has been chicken blood stone name is relatively large, this Bahrain chicken blood belongs to the rising star. From the fame of Bahrain's stone is a little worse. Because chicken blood is so precious, so attracted the counterfeiters rush. The following is a brief introduction to several methods of counterfeiting chicken blood stone:
One, synthetic. With rock powder plus glue plus color, this fake chicken blood stone light weight, easy to be identified. Selling price is also tens of dollars. There is also the use of resin fake chicken blood stone, with metal as the heart, increase the weight of fake chicken blood stone to achieve the feeling of stone. And these imitations, most of them to be mixed in some real bloodstone, let the buyer to pick, buyers are easily fooled. The way to recognize it is to take a magnet with very strong magnetic force and put it on the surface, it will absorb it. Because a thick metal bar must be added to the inside of the fake chicken-blood stone made through the rock-powder resin sandwich method. Its weight has increased a lot, otherwise, like glue, it should be light and fluffy. There is also the feeling that the chicken blood pieces are very dead, not blended with the surrounding ground. In addition, artificial things how can not create the natural beauty of the nature of the kind of ghostly craftsmanship to.
Two, paste skin. Because of the method of mixing stone powder with cinnabar, has been recognized by the collector, therefore, the counterfeiters and find out a more realistic method of forgery. They put the real chicken blood stone, with a saw broken into blood with the skin of the stone, wrapped in stone. Such a stone, can be broken into a lot of bloodstone chapter material. After this method of treatment into the fake bloodstone, often with some of the characteristics of the natural stone. The texture is natural enough to be fake. Such a stone main carefully observe, it will have what broken, it has three to be able to connect. Because the natural stone, it is only natural, no matter what stone, it is only shelved into a piece of stone, it will connect the texture. Because it is a whole, it is because of the surrounding package. Because it is a whole stone, there is a place where it will not fit. There's only one face, there's only one corner. It's just a line, it doesn't match, the grain doesn't match. So that's what's wrapped around it. Besides looking at this line. Also look at the four lines on the top and the four lines on the bottom. There are four interfaces at the top and four at the bottom. If they do not match, it is very telling
Three, inlay. Large chicken blood stone, because it can be sold for a good price, coupled with exquisite carving, but it is a rare work of art. Because such material is very difficult to find. So in order to make this work produce better results, often in certain places, a little splicing. Cutting is used to set the blood part of the stone into the stone. This method is only applied to large chicken bloodstone ornaments. There are many people who have made a fortune with this type of chicken bloodstone pendant. Counterfeit chicken blood stone ornaments, repeatedly in selling high prices. Counterfeiting technology is so advanced that even connoisseurs can't easily recognize it. Generally speaking large stone, no matter how big the stone should carefully observe the direction of the stone, it has the direction of the blood vein. If a piece of stone, the blood veins detached from the direction of the stone grain, this stone grain as a whole is horizontal, while the blood veins are vertical. Then the stone is most likely inlaid. With this real stone inlay (or splicing) method, there are no transition bands on the surface of the spliced bloodstone veins. But for such a large thing for combination. It and counterfeiting is still a certain difference, counterfeiting is to make people fooled to cheat people money. This big thing, as long as the stone is real, well at least there are technical content in it. Sometimes it is in order to make it produce a good artistic effect and inlay.
Four, laser. With the development of science and technology, counterfeiters also use high technology for counterfeiting. It is said that there is a laser coloring method. But few people know the specifics, because this thing has just begun. With this method has done the chicken blood looks beautiful, but after a period of time by the laser coloring of the chicken blood red on the loss of all black. Sometimes there are real and fake or a combination of real and fake. The difficulty of identification is even greater.
