Talc is a metamorphic mineral resulting from the metamorphism of magnesium minerals such as serpentine, pyroxene, amphibole, olivine, in the presence of carbon dioxide and water. This is known as talc carbonation or steatization and produces a suite of rocks known as talc carbonates. It is a natural mineral that is composed of four elements: magnesium, silicon, oxygen and hydrogen. The chemical name for talc is hydrous magnesium silicate. It is the softest known mineral It occurs in the regions where tectonic plates are present, replacing the rocks with heat and pressure, with the flow of liquids, but without melting. It has been an environment for carving for thousands of years. It is composed primarily of talc so it usually very soft. It is typically gray, bluish, green, or brown in color, often variegated. Its name is derived from its “soapy” feel and softness white odorless tasteless powder, insoluble in water but slightly soluble in dilute acids. Used in the production of decorative paints, industrial coatings, pigment pastes, primers and enamels. Also used in polishing pulses and printing inks. Due to our Talc’s minerals composition it is very much very much useful in Paper, Paints, Cosmetics, Rubber, PVC Industries.
