3. Perlite
is naturally occurring
siliceous amorphic
volcanic rock. But unlike
other volcanic glasses, if
heated them above a point
(8000-9000 C), they expand
up to 20 times of its
original volume.

4. As an amorphic volcanic
glass, perlite is mostly
made of silica or SiO2
(about 70-75%).
Other than there is a
mixture of Aluminum
Oxide or Al2O3, and
Oxides of Sodium,
Potassium, Iron,
Magnesium, and Calcium,
and moisture.
