Moyu is the main variety of Hetian jade, and it is also a high-quality jade variety. Hetian jade jade is grayish black to black, and the coloring factor is caused by containing a certain amount of graphite inclusions. Observing the authenticity of ink jade under strong light is a common method. Is the real Hetian Moyu opaque?
The real Hetian Moyu is opaque?
There are two types of ink jade: one is the jade of white jade, and the base of the jade is permeable with strong light. The white jade is doped with ink dots of different sizes. The other is the jade at the bottom of the sapphire. The illuminating of the base with strong light is only slightly transparent. Most of them can see the uneven distribution of ink dots, and some of them are hard to see the ink dots.
The color of the opaque line of the ink must look at the thickness, and the thin piece of ink is still light. The color of the ink is lighter and lighter, and the thickness is not transparent.
The real Xinjiang ink jade is made of graphite invaded into white jade. When you hit it with a light, you can see the white jade on the ground, with black dots on the stars. Of course, although the dark is the top grade, the edge of the jade should also be transparent. Because it is white jade, it is also very oily. Many times, because it is all black, because it can not see the bottom of the white jade, so that people are misunderstood as black stones, so the bottom of the white jade still has to be, just right.
The strong light transmission in the ink jade is that the inclusions are less, and the light transmittance of the inclusions is relatively weak. Therefore, some of the inks are leaking, and some of them are impenetrable.
As for this inclusion? There are many sayings, but the current academic circles have not finalized, but now the industry is more popular is the main component of the inclusions is magnetite, which is our chemistry school of ferroferric oxide.
Everyone knows that the characteristics of triiron tetroxide are: black solid, insoluble in water, magnetic, and conductive. Therefore, according to this nature, many people use magnets to identify the authenticity of ink jade. It can also be seen from this point that the stronger the magnetic properties of the ink jade, the more the wrapped iron is, and the corresponding light transmittance is not strong. On the contrary, the small magnetic jade has a strong light transmission.
