Perlite is a volcanic eruption of acid lava , vitreous rock formed by rapid cooling , because of its pearl fissure structure . Perlite ores include perlite , obsidian and turpentine . The difference among the three is that perlite has a circular arc crack formed by condensation , which is called perlite structure , with a water content of 2% and 6% ; Turpentine has a unique gloss of turpentine and water content of 610%; obsidian has a glass gloss and shell-like fracture , Water content is generally less than 2.

Perlite Application:

Expanded perlite for horticultural

In horticultural applications, perlite is used in expanded perlite ,which is used as a component of soilless growing mixes as it provides aeration and optimum moisture retention for superior plant growth. For root cuttings, 100% perlite is used. Studies have shown that outstanding yields are achieved with perlite hydroponic systems. Other benefits of horticultural perlite are its neutral pH and the fact that it is sterile and weed-free. In addition, its light weight makes it ideal for use in container growing. Other horticultural application of perlite includes as: fertilizer , herbicides and pesticides carriers and for seed pelletizing. Horticultural perlite is as useful to the home gardener as it is to the commercial grower. It is used with equal success in greenhouse growing, land-scaping applications and in the home in house plants.
