Product information

Perlite is a generic term for a naturally occurring siliceous rock.  The distinguishing feature that sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from four to twenty times its original volume.  This is due to the rapid expansion of water within perlite, which creates the extremely light perlite that we use within the garden arena, with many benefits when it comes to it's horticultural uses.
