Which is better, purple sand or red sand in cinnabar

Because the mineral content is higher than that of red cinnabar, the higher the cinnabar content, the higher the value. Purple cinnabar is the original mineral cinnabar and the first choice for collection, while red cinnabar is mostly worn as an ornament, so red cinnabar is better than purple cinnabar.

Red cinnabar generally has metallic luster and low hardness, and it is easy to leave scratches on the surface after contact with hard objects. Purple cinnabar, on the other hand, presents diamond luster, looks brighter, has hard texture and dense structure, and is the cinnabar choice of cinnabar at present. Cinnabar is a natural ore with mercury sulfide as the main component, with diamond luster to metallic luster, including many types of varieties, including raw ore cinnabar, reduced cinnabar, powdered cinnabar, cinnabar crystal, rootless sand and so on. Cinnabar crystal is the most expensive and best kind of cinnabar.

Identification method of cinnabar

1, tin foil heating method

It can be distinguished by the heating mode of tin foil. The real cinnabar is wrapped in tin foil. When heated against the tin foil, the color inside will gradually turn brown-black, with a crackling sound, and it will be gelatinous after liquefaction, while the color of the fake cinnabar will remain unchanged after blackening.

2. White paper heating method

Put a piece of white paper under cinnabar and heat it with alcohol lamp. If it is real cinnabar, it will turn black slowly and return to its original color after leaving the flame. White paper will not be dyed, but pseudo color cannot be restored, and white paper will be dyed.

3, soaking method

Put cinnabar in a clean container, add a proper amount of water, wait a moment and shake it a few times. The real cinnabar will not be dyed, and the sediment will be dark red, while the fake one will easily turn into water red and the sediment will be silver gray.
