Why Source Pumice from Hess
Much of our processed pumice is exported into countries and regions that often have domestic pumice sources nearby. They buy Hess pumice because they require a superior pumice product. Worldwide, our pumice enjoys advantages in whiteness (GE brightness of 84), hardness (Mohs' scale 6), density (specific gravity of 2.35 g/cc) and natural purity.

Pumice - an overview | ScienceDirect Topics
There are numerous density measurements of lapilli-sized pumice and scoria; the small size of individual ash particles, however, has limited direct density measurements. In general, silicic lapilli from sustained large (Plinian) eruptions are highly vesicular, with densities <1000 kg/m 3 (eg, Houghton and Wilson, 1989).Lapilli formed by fragmentation of either crystalline or partially degassed ...
