What is Perlite? Perlite is a volcanic rock mined in the United States, as well as other countries like China, Greece, and Italy. The volcanic glass, or perlite, is formed when lava (molten rock) spews out of a volcano, and cools in a rapid manner. Because of rapid cooling, water is trapped within the rock, and the lava forms into a glass-like ...

The resulting expanded perlite is a lightweight material full of tiny little air pockets; it is clean, sterile, and resists compaction. The pockets on the outside absorb water, blocking moisture from entering into the center of the perlite pieces. ... Diatomaceous earth typically comes in powder form versus a granular. When mixed into garden ...

After perlite is mined from the Earth, it is rapidly heated to 1400 to 1800°F by a giant "popper." The water contained in the perlite transforms to steam and causes each tiny "pearl" to bubble up to 20 times its original volume. The result is "expanded" perlite which is much like popcorn.
