Rhyolite: Perlite's Angry Foe When mining raw perlite ore, we often come in contact with rhyolite, a pale fine-grained volcanic rock of granitic composition, typically porphyritic in texture. In many ways they are similar; they both have volcanic origins and high silica content.
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.
This expansion process also creates one of perlite's most distinguishing characteristics: its white color. While the crude rock may range from transparent light gray to glossy black, the color of expanded perlite ranges from snowy white to grayish white.

Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian.It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral and a commercial product useful for its low density after processing.
Perlite, also called pearlstone, a natural glass with concentric cracks such that the rock breaks into small pearl-like bodies. It is formed by the rapid cooling of viscous lava or magma. Perlite has a waxy to pearly lustre and is commonly gray or greenish but may be brown, blue, or red.

Perlite is a naturally occurring siliceous rock that expands 4 to 20 times its original size when rapidly heated to approximately 1,700 °F. In reality, expanded Perlite is a "popped rock" that is inert, lightweight, sterile, permanent, incombustible, asbestos-free, non-toxic, rot and vermin proof and has a neutral pH.
Perlite is an extrusive rock that forms when a high-silica lava has a high water content. It is an important industrial material. This type of igneous rock forms when a body of rhyolite or obsidian, for one reason or another, has a high water content.

This helps you avoid pest problems! Perlite is also pH neutral, unlike some media like expanded shale and rock wool.
The expansion process also creates one of perlite's most distinguishing characteristics: its white color. While the crude rock may range from transparent light gray to glossy black, the color of expanded perlite ranges from snowy white to grayish white.

Perlite has the unusual characteristic of expanding and becoming porous when it is heated. It can expand to as much as twenty times its original volume. Expansion occurs when the glassy lava rock is heated to 1600 degrees F (871 degrees C) and the water molecules trapped in the rock turn into vapor causing the rock to expand.
