    shale is a sedimentary rock: hardened layers of clay, silt and other minerals — essentially very old mud. when crushed and fired in a rotary kiln at 2,000 degrees fahrenheit, tiny air spaces in the shale expand like rice krispies. the result — expanded or vitrified shale — is a lightweight, gray gravel.
