Its chemical formula is H2Mg3 (SiO3) 4 or Mg3Si4O10 (OH) 2. It is found as a leafy and scaly mass. The binding of certain properties is very similar to that of mican. All talc species are found in nature in the form of steatite and soapstone. There are large talc deposits in the USA, California, Washington and Texas in various places of the Appalachian Mountains.
Production and Reactions
Naturally, it can be removed in most places as pure or impure. Talc; It consists of the change of olivine and other magnesium minerals such as serpentine.

It is very soft in pure form, it can be used as talcum powder and face powder.
It is used in ceramic industry because of its resistance to fire, heat and electricity.
Technically, it is used as a lubricant to prevent wear of machine elements.
Talc's impure soap soap is used in laboratories to make acid-resistant bench tops and sinks.
It has been used as a filler in the rubber, paint and paper industry, in the construction of air-resistant cements, as soapstone for thousands of years for engraving and vase construction.
