Pumice is a very light weight rock - it floats in water. It is part of the ejecta of a composite volcano. It may be found in streams or on Coastlines nearby to composite volcanoes. If you wanted to buy a small quantity, then one of the science supply houses would help.

∙ 15y agoPumice is formed when lava cools very quickly ABOVE ground. The vesicles or tiny holes all over are formed when heavy amounts of gas escape from the lava while cooling, leaving those air pockets. Even though it doesn't seem like it, pumice has a glassy texture just like obsidian glass, both of which form in very similar ways.
