Which is better vermiculite or perlite?

Perlite is a hard, highly porous material made by super-heating volcanic glass. Vermiculite retains more water and retains it for longer periods than perlite. Vermiculite affords slightly less aeration than perlite. For plants that thrive growing in a more-wet soil, vermiculite would do well as a potting soil additive.

Does perlite contain asbestos?

While breathing any type of fine dust is not good for your lungs, you don't have to worry about asbestos contamination with perlite. Perlite is a volcanic glass, and asbestos is a fibrous form of a mineral. They are not normally found together in nature.

Which type of asbestos has the best fire protection properties?

Chrysotile is the most commonly used type of asbestos and is often contaminated with trace amounts of tremolite.
