In recent years, the South Red Agate, which is becoming more and more popular in the wenwan market, is also unable to escape the hands of counterfeiters. They use the professional method to imitate Nanhong, confuse friends and buyers. How to identify the imitation of South Red? Understand the following methods, should help identify the true and false South Red. 1. Artificially burned agate. Since the agate contains ferrous ions, the counterfeiter uses this to oxidize the ferrous ions to ferric ions by artificially burning the color, thereby turning the white or gray agate into a red color. However, the artificially burned color is not naturally formed after all. The burnt color is not transparent, the color is uneven, and the red color floating on the surface does not fuse with the material. 2. Artificial staining. Not all agates contain ferrous ions. For those agates with low iron content, the counterfeiters usually dye the agate in a chemical solution for a while, then heat and acidify it to make it Turns red. This dyeing method is observed by a high magnification magnifying glass, and it can be seen that the color is infiltrated along the gap of the agate, and there is no fine gelatinous texture of the southern red agate. 3. Manual injection. The agate after injection is relatively easy to identify, because there will be a transparent inclusion of small bubbles in the outer layer. When viewed with a magnifying glass, it will be found to have a filament-like transparent grain inside, and a large penetration and natural texture. There are obvious differences.
