Its powder is called pumicite. The pumice structure is due to simultaneous rapid cooling and rapid decompression. Depressurization generates bubbles by reducing the solubility of gases (including water and CO2) dissolved in lava, leading to rapid gas evolution. At the same time cooling and depressurization freezes the bubbles in the matrix.
