How vermiculite is made - material, history, used ...

In its expanded form, vermiculite has a very low density and thermal conductivity, which makes it attractive for use as a soil amendment, lightweight construction aggregate, and thermal insulation filler. Expanded vermiculite also has a very large chemically active surface area, which makes it useful as an absorbent in some chemical processes.

Feb 14, 2012 · Vermiculite absorbs water, so the commercial mix is probably treated with something to avoid water retention. Perlite does not absorb water, but concrete grade perlite, (small sand size granules) seems hard to find. I found some but I will have to drive to the perlite processing plant 100 miles away to get it.

Perlite | Imerys

Perlite is a generic term for naturally occurring siliceous rock. It is a form of natural glass which like pitchstone, obsidian and other similar contains "combined water". Perlite (containing 1,9% – 4,8% wt. "chemical" or combined water) was formed over a few million years by the chemical weathering of obsidian at the earth's surface.
