The following expanded shale information e ... This process causes tiny air spaces in the shale to expand. The resulting product is called expanded or vitrified shale. This product is a lightweight, gray, porous gravel related to the silicate soil amendments perlite and vermiculite. Adding it to heavy clay soil lightens and aerates the soil.
