Product Description

pumice stone from volcanic eruption.We can provide different sizes according to your needs.There's a lot of use of this product from construction up to cosmetics.Pumice is created when super-heated, highly pressurized rock is violently ejected from avolcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering thesolubility of gases (including water and CO2) that are dissolved in the lava, causing the gases to rapidly exsolve (like the bubbles of CO2 that appear when a carbonated drink is opened). The simultaneous cooling and depressurization freezes the bubbles in the matrix.
