Volcanic glass is formed by rapid chilling of liquid lava when it comes into contact with the atmosphere, water, or cooler adjacent rocks. It occurs mainly as obsidian, pitchstone, and perlite in lava flows, domes, and dykes, and as pumice, cinder, and ash in pyroclastic rocks. The tendency of lava to form glass is a function of rate of cooling

· Perlite is a type of volcanic glass formed when lava cools rapidly. It has a unique structure composed of tiny, closed cells that contain a small amount of water. When perlite is heated to a high temperature, the water inside the cells vaporizes, causing the cells to expand and create a lightweight, porous material.

Perlite is a type of volcanic glass that expands and becomes porous when it is heated. When heated it can expand to as much as twenty times its original volume. This expansion is the result of heated water when the glassy lava rock is heated to 1600 degrees F (871 degrees C) the water molecules trapped in the rock turn into vapor which
