Mineral resource of the month: perlite




Perlite is found in most homes, workplaces and schools. Most of the white ceiling tiles in offices and classrooms are made primarily of perlite. The soil around potted plants also has small white grains of perlite. Other than in these lightweight construction products and horticultural soil mixes, perlite is used in food processing for filtration and in natural gas processing as a low-temperature insulation that aids the gas liquefaction process. Perlite is also an excellent high temperature insulator and resists burning.
