What is a light weight amendment by its common name?

Pumice

A light, porous volcanic rock that forms during explosive eruptions. It resembles a sponge because it consists of a network of gas bubbles frozen amidst fragile volcanic glass and not a mixture of minerals. Pumice is similar to the liquid foam generated when a bottle of pressurized soda is opened. The opening depressurize the soda and enables dissolved carbon dioxide gas to escape or erupt through the opening. During an explosive eruption, volcanic gasses dissolved in the liquid portion of magma also expand rapidly to create a foam or froth; in the case of pumice, the liquid part of froth quickly solidifies to light rock material. Once the gas dissipates it leaves a very porous material, that is 72% air and 28% solid material.
