Sodium silicate Wikipedia

Sodium silicate is a generic name for chemical compounds with the formula Na 2x Si y O 2y+x or (Na 2 O) x · (SiO 2) y, such as sodium metasilicate Na 2 SiO 3, sodium orthosilicate Na 4 SiO 4, and sodium pyrosilicate Na 6 Si 2 O 7.The anions are often polymeric.These compounds are generally colorless transparent solids or white powders, and soluble in water in various amounts.

Vermiculite Statistics and Information USGS

Flakes of raw vermiculite concentrate are micaceous in appearance and contain interlayer water in their structure. When the flakes are heated rapidly at a temperature above 870° C, the water flashes into steam, and the flakes expand into accordion-like particles. This process is called exfoliation, or expansion, and the resulting lightweight material is chemically inert, fire
