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. This expansion is due to the presence of a small percentage of moisture in the crude perlite rock.

Perlite is an inert glassy volcanic ryholitic rock and can be expanded up to 10– 20 times its original volume when heated rapidly at 760–1,100ıC (Tekin et al., 2006). Expanded perlite (EP) acts as an excellent insulator, both thermal and acoustical, and is classified as ultra-light weight material.
