Procision Perlite Regular is cut with a 20 mesh screen leaving all material to retain #5. Perlite ore is a naturally occurring volcanic glass containing a small percentage of water. When that ore is introduced to tremendous heat the glass liquefies and the trapped water expands creating a remarkable and versatile material.
