What You Need to Know about Expanded Perlite. Perlite is a generic term for naturally-occurring sedimentary rock that contains silicon, aluminum, potassium, sodium and other trace minerals. What sets perlite apart from other volcanic glasses is that when it is heated to its softening range, it expands from four to twenty times its original volume.
