Pumice is not a specific mineral. It is a highly vesicular volcanic glass, originating as one of the common acid volcanic rocks and containing dissolved CO2 or H2O, at high temperatures. Upon the pressure release in a volcanic explosion, the dissolved gases expand greatly to create the familiar low density light coloured material. Commonly 90% of the material is bubbles or their frozen remains.
Scoria is a similar material, but is darker and much heavier, reflecting the source rock and conditions from which it originated.
