Pumice is categorized as an extrusive igneous rock. Extrusive rock formations are made when molten lava flows from the interior of the Earth and solidifies on the surface. More »

Pumice is an igneous rock formed by the rapid cooling and depressurization of volcanic magma with a high gas content. It is characterized by a large amount of vesicles formed from gas bubbles in the magma. More »

Pumice rock is found all over the planet and on every continent. This textured rock is formed when volcanoes erupt, and it is carried from shore to shore after being generated by underwater volcanoes. The molten rock com... More »
