perlite

Perlite is a natural volcanic glass that expands when heated rapidly, creating small, lightweight, porous particles. These particles are commonly used in gardening and construction because they improve soil aeration, drainage, and insulation. In gardening, perlite helps roots breathe and prevents waterlogging, promoting healthy plant growth. In construction, it’s used as an insulating material and a lightweight aggregate in cement or plaster. Perlite is inert, non-toxic, and resistant to pests and mold, making it a versatile and effective additive for various applications where lightweight, insulating, or aerating properties are desired.
