On the Mohs Scale, Talc is one of the main standards for measuring the hardness of minerals, occupying first place as the softest mineral.
In its most common use, Talc is used in the manufacture of paper and cardboard, for lacquers and paints, in the ceramic industry and as an additive to rubber and plastics. Due to its resistance to high temperatures, it is used in the manufacture of heat-resistant materials.
One of its best-known uses is in powder form to prevent skin irritations and hydrate it.
