On the Nature of Fluorite
Fluorite is a kind of thing. Its nature is specific, and in various physical and chemical environments, it often shows a single state.

The color of fluorite, or plain white like snow, is uniform and pure, and it looks like the cleanliness of ice crystals, without variegated dyes. Under the light, it is slightly flooded, radiant and smooth, like the luster of jade, but it is not the warm touch of jade, but has its unique rhyme.

Its quality is solid at room temperature, firm and brittle. If you hit it with an object, it is easy to form crushed powder, and the crushed powder is fine like dust powder, with distinct grains. When you touch it, you feel slightly astringent, without a feeling of slippery.

On its chemical properties, when it encounters acid, it may change wonderfully. When it encounters strong acid, a violent response often occurs, which dissolves gas and rises, the color is clear and the taste is strong, the smell is pungent, and it has the ability to erode. If it is used in alkali, it also responds, but it should be slower than acid, or new compounds are formed, and the color and shape are different, depending on the type and amount of alkali.

Alum fluoride also changes in nature when it is in a hot environment. It melts gradually when heated, from a firm and brittle state to a soft flow state, like a state of melting gold, to be cooled and solidified. Its quality may change slightly, and its firmness may increase or decrease slightly, depending on the degree and duration of heating.

It often plays a key role in all kinds of chemical things. Helping it to integrate, change its nature, and increase its energy is indispensable in many materialized works. The world explores its nature and makes good use of it for the benefit of people's livelihood.
