Agra-perlite (perlite)

Perlite is a porous, white pellet. Mainly used to create airiness in a potting soil.

Raw Perlite raw material is an inorganic rock. This rock was created during volcanic eruptions. The rock is purified and crushed to different gradations. The manufacturer processes this raw material in special ovens at a temperature of about 950 °C. During this expansion process, the bound water, in the ore, passes into vapour form. At the end of the production process, a white, porous, lightweight grain is created: Perlite.
