Perlite

Perlite is a naturally occuring volcanic glass. When quickly heated above 800≧, perlite expands up to 20 times its original volume. This expansion is due to two to six percent combined water in the perlite ore.

Perlite is natural, non-toxic, inert, lightweight, incombustible, asbestos free, virtually pH - neutral. VERMMINING manufactures a variety of Perlite products for horticultural, industrial and construction applications.
