The raw material of the ink jade is also known as the “blue and white materialâ€. Since the black part of the black jade is not very uniform, only the black content of more than 40% can be called the real jade. As the market price of blue and white ink jade continues to increase, more and more counterfeit blue and white inks are pouring into the market. The following materials are the most common imitations in the market.
Qinghai tobacco material: The color of this material is very black like the naked eye, but it has a very obvious difference with the blue and white ink jade. If the light is applied to the surface, it will be found to be faint. Purple light, while blue and white ink jade does not have this phenomenon.
Black Jasper: The color of black jasper is very dark, but the surface of the light will show green or cyan light on the surface of the light, and the blue and white ink jade is formed by the intrusion of graphite. So no matter how you observe it, it is just the original color of jade.
The blue-and-white jade contains graphite, so the graphite crystal is in the form of a sheet, and if the wafer is relatively large, sheet-like reflection occurs under the illumination of strong light. Blue and white ink jade is relatively thin, the color is slightly lighter, it will be translucent. Some blue and white ink jade is only black, it looks very textureless, so it can not be regarded as a good quality blue and white jade.
