Question 8: What stone has the lowest hardness? Talc is that low hardness stone in the world at present!

Talc is a hydrothermal altered mineral. Magnesium-rich minerals are often transformed into talc after soaking, so talc often presents mineral illusions such as olivine, enstatite, amphibole and tremolite. Talc is a common silicate mineral, which is very soft and greasy. People choose the mineral of 10 to represent the hardness grade of 10, which is called Mohs hardness. In this 10 grade, the first one (that is, the softest one) is talc. Soft talc can be used to draw white spots instead of chalk. Talc is generally in the form of blocks, leaves, fibers or radiations, and its color is white and off-white, which will show various colors due to other impurities. Talc has many uses, such as refractories, paper, rubber fillers, pesticide absorbents, leather coatings, cosmetics and carving materials.
