Perlite is a popular commodity used in a variety of industrial, agricultural, and horticultural applications. It is a volcanic glass that has been superheated to create tiny bubbles or pockets of air, which give it a lightweight and porous texture. The origin of perlite can be traced back to volcanic regions, where it is formed when volcanic glass comes into contact with water and is quickly heated to high temperatures.

The primary uses of perlite include as a lightweight aggregate in construction materials, a soil additive in horticulture, and a medium for growing plants in hydroponics. In construction, perlite is used to reduce the weight of concrete, improve insulation, and increase soil aeration. In horticulture, it is commonly mixed with soil to improve drainage and moisture retention. Additionally, perlite's porous structure makes it an ideal medium for growing plants in hydroponics, allowing water, nutrients, and oxygen to flow freely to plant roots.

Perlite is produced by crushing and heating raw volcanic glass to temperatures of around 1,600 to 1,800 degrees Fahrenheit. This causes the glass to expand and form a white, lightweight, and porous material. After expansion, the perlite is graded and packaged for various applications. The final product is inert, odorless, and does not decompose over time, making it a versatile and long-lasting commodity.
