Talc is a metamorphic mineral resulting from the metamorphism of magnesian minerals such as pyroxene, amphibole, olivine and other similar minerals in the presence of carbon dioxide and water. This is known as talc carbonation and produces a suite of rocks known as talc carbonates.It occurs as foliated to fibrous masses, its monoclinic crystals being so rare as to be almost unknown. It has a perfect basal cleavage, and the folia are non-elastic, although slightly flexible. It is sectile and very soft, with a hardness of 1 (Talc is the softest of the Mohs’ scale of mineral hardness). It has a specific gravity of 2.5–2.8, a waxlike or pearly luster, and is translucent to opaque.At Ashapura China Clay, talc is available in white powder form.
