Perlite
Perlite is a naturally occurring volcanic glass that expands when heated. It is a type of amorphous volcanic glass that forms when obsidian, which is a more crystalline form of volcanic glass, undergoes rapid cooling. Perlite is often used in horticulture and gardening as a soil amendment to improve aeration and drainage in soil mixes. It is lightweight and has the ability to retain some moisture while allowing excess water to drain away, making it a popular choice for potting mixes.
In addition to its horticultural uses, perlite is also used in construction and industrial applications. When heated, perlite expands and becomes a lightweight, white, granular material that is used as insulation in building materials. It is also used in the production of concrete and plaster, as well as in the filtration of liquids in various industrial processes.
Overall, perlite is a versatile material with a wide range of applications, particularly in agriculture, construction, and industry, where its unique properties are valued.
