It is a volcanic rock with water droplets. When exposed to high temperatures, the particles expand because the water in the mass tries not to evaporate then and porous expanded perlite granules at low
density are obtained. Perlite, which has many physical properties as a result of the expansion process, is used for different purposes in different sectors such as agriculture, construction and industry.
Perlite is important with its low density, physical flexibility, chemical stability, low sound permeability and fire resistance. It is successfully used as a soil conditioner in greenhouses, as an additive
in seedling mortars and as a growing medium in soilless agriculture. Perlite is a very suitable environment for the germination of vegetable and flower seeds.
