SUPERIOR VERMICULITE

PRODUCT INFO

Vermiculite was first described in 1824 for a occurrence in millbury , Massachusetts USA.

Its name is from latin vermiculare, to breed worms , for the manner in which it expands when heated.

Vermiculite is a hydrous , silicate mineral that is classified as a phyllosilicate and that expands greatly when heated. Expandsion occurs when the mineral is heated sufficiently, and the effect is routinely produced in commercial furnaces. Vermiculite is formed by weathering or hydrothermal alterion of biotite or phlogopite . large commercial vermiculte mines currently exist in Russia , south Africa , china and brazil
