Perlite ores can be described as fragmented forms of volcanic rock with distinctive sheen. These ores have distinctively glassy appearance and these tend to expand in volume when heat is applied on these within the range of their softening temperature point. Perlite ores are used as important ingredients for plaater mixes, thermally and acoustically insulated roof tiles etc. These ores are also used in agricultural arena for maintaining porosity of soil to improve water absorption capacity of soil. These ores are accessible at reasonable rate.
