What is Vermiculite?

Vermiculite is a hydrous phyllosilicate mineral that is mined in Russia, South Africa, China and Brazil.

It can be used in fibrous form, not unlike fibreglass or it can be molded or used in liquid form. Its most useful properties are its ability to withstand very high temperatures.
