Description
Perlite is a natural volcanic glass. There are many natural volcanic glasses around the world but the key feature for perlite is that when it is heated it expands. The expansive process is a lot like making pop corn. The resultant expanded perlite can be 20-30x its original bulk density. The process of expansion targets the combined water content within the raw perlite – the water trapped in the perlite ore – which vaporizes under heat and creates a glass bubble.
