What is ink?

The commonly known terrazzo is not jadeite, but a mineral similar to jade. The associated minerals of jadeite are often used as jadeite of glass or ice, but they have low refractive index, low density, low hardness and stone brain. If there are floating flowers, the mineralogical characteristics of the ink stone often belong to albite, and its color is white and transparent, like ice jadeite. Therefore, it is often deceived by unscrupulous merchants to sell the jadeite with ink stone as ice and make huge profits. Because it is not the same substance as jade, its mineralogical characteristics, such as hardness, specific gravity and refractive index, are different, which will be known after identification.
