Perlite

Perlite is an amorphous volcanic glass with a high-water content. When heated to a high temperature the granular product expands like popcorn resulting in tiny bubble structures. Perlite is used extensively to reduce the weight in a wide variety of construction materials and packaging. When used in agriculture, it provides aeration and optimum moisture retention. The internal bubble structure also provides high absorption and thermal resistance capabilities.
