What is Vermiculite?

Minerals are solid substances, occurring naturally. Minerals are not organic compounds as their origins are inorganic. Interestingly, the process of formation of minerals do result from organic processes. What is Vermiculite? Here you can know all about it. Vermiculite mineral belongs to Phyllosilicate minerals. You can know more about the Physical Properties of Vermiculite and find out all the aspects pertaining to the appearance and form of a mineral. It is also important to know the IMA status of a mineral, for this mineral IMA status is Valid Species (Pre-IMA) 1824. Another important aspect is the minerals strength or hardness, Vermiculite has Mohs Hardness between 1.5-2.
