What is Vermiculite Rock?
Vermiculite is a naturally occurring mineral that can expand many times its original size when heated. This expansion property makes it highly valuable in various industries, including agriculture, construction, and horticulture.

Formation of Vermiculite Rock
Vermiculite is formed from the weathering of biotite, a mica mineral. When biotite is subjected to heat, it breaks down and expands into vermiculite. This process typically occurs at temperatures between 350°C and 600°C.
