Seriously, I am worried that the South Red you bought is fake.
In the agate family, Nanhong is warm and moist like jade, and the lines are few and evenly known. In recent years, the value of Nanhong has risen and the day is red. However, behind the skyrocketing price, many unscrupulous traders have made huge profits in order to reduce costs and use various methods to create counterfeit South Red. Knowing ourselves and knowing each other is not a battle. In fact, when investing in the collection of Nanhong, as long as you know the current fraudulent means on the market and simple and rude screening methods, your eyes may also be eye-catching. The first part of the fake technique Burnt color Burnt color usually means heating and firing a light-colored agate containing a large amount of iron. In this agate, the iron element is preheated to become red, so as to deepen the color of the agate, so as to achieve the effect of the real red agate. Compared with the real South Red Agate, the light-colored agate with burnt color is more translucent and transparent, and it lacks the lubricity of South Red. Identification method 1, see the material Burnt color fake South red has a glassy feel, through the bottom, crisp. Moreover, the burnt-colored fake South Red will also have a glassy texture of cracks and cracks. Moreover, fine cracks can occur during the firing process, and can be seen with a 10x magnifying glass. 2, look at the color The color of the fake South Red is sluggish, commonly known as "color boring" or "dead color." The amount of red burned is not clear and bright, which is unique to Nanhong Agate. The color is not moving, and it is stagnant. Fragmentation dyeing The true color of the dyed red red agate is a light-colored agate with less iron inside, which cannot be changed by firing, and can only be artificially dyed. The principle of artificial dyeing is to first soak the light-colored agate with an iron solution. After about one month, it is fired to red color, which is similar to the red red agate. Identification method Such a fake South Red lacks the texture of Nanhong, which is more difficult and dull. And when viewed under a 10x magnifying glass, you can also see the staining traces of the mesh and unevenness. Fragmentation Injection The injection molding method is filled with a colorless, almost transparent epoxidized resin, which has been used to repair the excessive redness and adhesion cracks of the enamel-like inclusions. The southern red is generally rich in the state, but still in the national standard. Belongs to processing. Identification method The filled southern red looks very rich and full, and the color is naturalr than dyed. However, with a 10x magnifying glass, it is possible to see small bubbles and a transparent, slender flat linear wrap, which is caused by the filling of the resin glue. shaoxing zhentu trading co;ltd , https://www.zhentutextile.com
