Talc is crystallized in the formula of Mg3Si4O10

Talc Talc is crystallized in the formula of Mg3Si4O10 (OH) 2 in the mono-clean system and belongs to the group of minerals of the group of phyllo-silicates. The arrangement of the elements in this mineral is such that the free oxygen of the two layers, or in other words the free vertices of the tetrads, are placed opposite each other. These two layers are connected by elements such as AL+ or Mg+ 3, and generally a very strong double network is created. Talc mono-crystals are fine and transparent, and are mostly in the form of scaly, bowl-like grains, fibrous filaments, and generally dense, fine-grained grains. In scaly grains, the excellent separation level of talc is visible and it has a shell polish on the cleavage surface. With a hardness of about one and a low specific gravity (2.8 2.7 grams per cubic centimeter), its touch is greasy and affects on the hand. Talc is a colorless, white mass, and its single crystals are pale or blue if coarse. Its mass type is found in impurities in different colors of mud, light yellow and light gray, which is also called Speeskstein talc or oily stone. Due to high heat, its hardness increases to 6. Ordinary acids are ineffective in talc. Minnesotaite is called talc to replace magnesium with a significant amount of iron. (Fe) where = H 01/3 and is generally colorless or light green. Colorless dense granular talc is also called sewing soap.
