Igneous Rocks

Pumice is an Igneous Rock that can be used to scrape dry and excess skin off of the bottom of a foot. Granite is another Igneous Rock that can be used for countertops and flooring in modern-day homes. Obsidian is used for modern-day scalpels. Gabbro is mostly used for cemetary headstones. Basalt is used for making cobblestone, and statues. This is a picture of an obsidian scalpel.
