Ryolex is our brand of expanded perlites we refer to as macroparticles. These coarser particles are produced by heating crushed perlite between 1600 and 1800 F, causing the particles to expand 4 to 20 times due to the vaporizing of water in the rock. This expansion accounts for Ryolex's light weight and other exceptional physical properties.Web
