Perlite is a naturally occurring siliceous volcanic rock. The distinguishing feature which sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range it expands twenty times its original volume or more. This expansion is due to the presence of 2% to 6% combined water in the crude perlite rock.

A process for making articles from perlite material includes grinding raw perlite to a particle size <200 μm. The ground perlite is mixed with ground silicon carbide powder and moisture added in an amount to achieve a homogeneous mixture having the property of being thixotropic. The mixture is introduced to a mold and agitated to assume the shape of the mold.
