How to maintain fluorite? The value of fluorite?
Fluorite comes from the remnants of volcanic magma. During the cooling process of magma, the gas-water solution separated from magma contains many substances, mainly fluorine. In the process of the solution rising along the fracture, the temperature and pressure decrease, and fluoride ions in the gas-water solution combine with calcium ions in the surrounding rock to form calcium fluoride, and fluorite is obtained after cooling and crystallization. The crystal is glassy, brightly colored and fragile, with Mohs hardness of 4 and melting point of 1360℃. -Quoted from Baidu Encyclopedia

The main component of fluorite is the main source of fluorine in hatching excrement, which is widely used in industrial industry and optics. Fluorite can be used as a cosolvent to remove internal impurities when refining steel or making glass, and improve the performance and quality of industrial products. In addition, many lenses in optical instruments, such as cameras and microscopes, are made of Shi Ying material, which has better light transmission and smaller chromatic aberration. The history and culture of human using fluorite is quite long. From Hemudu culture period, people used fluorite as an ornament. /kloc-in the 0/8th century, Britain mined a lot of fluorite, and people gradually realized its own value.

In the field of art, it is often used as an ornament and foil for other jewels. Usually, attention should be paid to maintaining its own ornamental value, and it should not be in contact with any acid and alkali substances, otherwise it will cause corrosion.

In addition, don't put it in a high temperature environment to avoid direct sunlight, otherwise it will find the phenomenon of thermal expansion and cold contraction, destroy the internal physical structure and affect the chemical composition. Fluorite specimens can be used for collection, decoration and carving handicrafts, and high-quality fluorite can also be bought at a good price.
