1, hardness. The chemical composition of chrysotile asbestos is fibrous strain of nickel, and its Mohs hardness is 6.5-7, so it is a hard material and can be tested with hard objects with hardness lower than this. Chrysotile is harder than glass, so the selected chrysotile can be used to carve glass. If the trace is obvious, it is really chrysotile. Don't use anything too hard to avoid scratching its surface.

2. color. Chrysotile asbestos is yellow and even, unlike jadeite, which has colored roots and veins.

3. structure. The polished surface is as smooth as glass, without orange peel effect and particle structure. To the naked eye, its luster is oily to glassy, translucent to opaque.

4. Physical properties. The relative density of chrysotile is about 2.6, which is much smaller than that of jadeite, but small products are not easy to distinguish by hand, and can only be accurately determined by measurement. The refractive index of chrysotile is about 1.54, which is smaller than that of jadeite. At the same time, chrysotile lacks the characteristics of visible light absorption spectrum and Cr absorption spectrum.
