In fact, this kind of stone is talc, which is also the softest mineral known in the world at present, and its Mohs hardness is 1 (Mohs hardness is a standard to distinguish the hardness of stones, which is divided into 10 grades, and the higher the value, the greater the hardness, the smaller the value and the smaller the hardness). Because the hardness of talc is very small, it can leave scratches on the surface even if it is gently slid with fingernails. It is understood that talc is generally white and a common silicate mineral. It is formed by the metamorphism of rocks and has a very delicate feel.
It is understood that talc is edible, and it also has quite a number of functions, not only clearing away heat and relieving summer heat, eliminating dampness and healing sores, but also treating eczema and miliaria, and even promoting diuresis and stranguria. Generally speaking, talc is of great benefit to human body. It is worth mentioning that talc can't be eaten directly, and it must be refined before it can be eaten. After all, things mined in nature contain a lot of metal substances.
This kind of stone is called talc, which is also the softest mineral known at present. The Moho hardness scale is only 1, and even a slight stroke can leave scratches on it. The color of talc is generally divided into white, slightly cyan or green, which is formed by the same deterioration of rocks. It is also a common silicate mineral, which has a greasy feel and good softness. Moss hardness? It means 10 minerals to represent 10 different hardness levels.
At present, a large amount of talc has been found in Henan province, China, with a storage capacity of 8 million tons. In addition, a large amount of talc has been found in other places, with a total storage of 250 million tons. What do you think of this?
