This rock has been used in concrete mixtures for thousands of years and continues to be used in producing concrete, especially in regions close to where this volcanic material is deposited. The vesicles are actually gas bubbles that were trapped in the rock [18], Chile is one of the leading producers of pumice in the world. This rock is a trap to volcanic gases that tried to escape from magma but were unable to do it because they simply could not break out and formed many gas-filled vesicules instead. Good soil requires sufficient water and nutrient loading as well as little compaction to allow easy exchange of gases. Pumice is a pyroclastic (meaning it is formed from volcanic matter), igneous rock. People then discovered how to skillfully break the obsidian to produce cutting tools in a variety of shapes.
