Let’s zoom out. Scoria (another bubbly lava rock) is used in lightweight concrete blocks. Your garden path might be paved with it. And tuff—rock made from volcanic ash—is used in Roman-style architecture and even as a filter for water purification. Think of it as the roommates of the rock world: versatile and not always pretty.
Describe the Uses of Igneous Rocks
Road salt? Sometimes mixed with crushed basalt for traction. Dental abrasives? Pumice again. Your toothpaste might have volcanoes in it. That’s right—your morning routine includes a fiery, explosive exfoliation for your teeth. Minty and apocalyptic.
Even crayons have used ground pumice as an abrasive. Imagine a volcano scribbling in a coloring book. Picasso would be jealous.
