Industrial perlite is produced in two stages. Firstly, natural perlite is mined, crushed, dried and screened at the mine site to yield crude perlite. In the second stage, perlite is rapidly heated for a short time to temperatures between 800oC and 1000oC to yield expanded perlite, a sterile ultra-lightweight aggregate.

The demographic transition model was initially proposed in 1929 by demographer Warren Thompson. The model has four stages: pre-industrial, urbanizing/industrializing, mature industrial, and post-industrial. In the pre-industrial stage, crude birth rates and crude death rates remain close to each other keeping the population relatively level.

Perlite is a form of naturally occurring silicon rock. It has the distinctive property of expanding to 4 to 20 times its initial volume when heated at a particular temperature. This happens because the raw Perlite rock consists of 26% water. When it is heated above 870°C, crude perlite rock becomes swollen and tiny sealed glass bubbles form.

Perlite is a unique volcanic mineral which expands from four to twenty times its original volume when it is heated. Perlite can reach temperatures of approximately 1600-1700 degrees F. The media's expansion is due to the presence of two to six percent combined water in the crude perlite rock, which causes the perlite to pop in a manner similar ...

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.

Perlite is a volcanic mineral that can grow up to 20 times its original volume when heated at high temperatures (1600º to 1700ºF). Crude perlite contains water that pops like popcorn when heated. Perlite won't absorb any liquid but will create tiny spaces within the soil to improve aeration and drainage for the marijuana plant's roots.
