Expanded Perlite. Perlite is a generic term for naturally occurring siliceous rock. It is distinguished from other volcanic glasses, when heated to a suitable point in its softening range, it expands from four to twenty times its original volume. This expansion is due to the presence of two to six percent combined water in the crude perlite rock.
