Perlite - Amorphous Volcanic Glass, Grade Aa & A | High Silica Content, Lightweight Insulation, Soil Amendment, Non-compacting Filter Aid

Perlite is an amorphous volcanic glass, It occurs naturally and has the unusual property of greatly expanding when heated sufficiently, Because of its low density it has many commercial applications In the construction and manufacturing fields, it is used in light weight plasters and mortars, insulation and ceiling tiles. In horticulture, perlite can be used as a soil amendment and helps prevent soil compaction. Perlite is an excellent filter aid. It is used extensively as an alternative to diatomaceous earth. Small quantities of perlite are also used in foundries and in ceramics as a clay additive.
