Perlite: An adaptable Mineral


You must have seen those little rocks in many soil and potting mixtures! The mineral you are looking at is called Perlite. The white magic mineral has many befits including increased aeration, water retention and drainage. The uses of Perlite go above and beyond. Not only is it a great addition to your garden but can be used in other avenues such as loose-fill insulation and Masonry Construction. Perlite can be used to fill in cement as well and you could also use perlite to filter out nasty toxins in your swimming pools. The uses of  Perlite range from a variety of construction applications and consumer-based products.

What are the main properties and what are the origins of Perlite?


Perlite is primarily made of Volcanic rock glass which is formed by submerging lava in water. The mineral is made purely due to the drop in the temperature when lava cools down so quickly. The heated temperature is so extreme that the volcanic rock expands up to 16 times its initial size. This is one of the main reasons why Perlite is elastic and versatile.

The variety of uses of Perlite


The structure of perlite particles shows several microscopic passageways that provide air- and water-holding qualities that are helpful in many industrial and commercial applications when the water content is released through intense heat, enlarging the particles. In most situations, the utilisation of expanded perlite is determined by its size and quality. Air filtration, liquid filtration, fillers, and abrasives are exceptions to this rule.
