After the cooling is complete, you are left with igneous rocks – cooled lava that can take various forms depending on the way that lava was released, and what was contained within it when it came to the surface. It is commonly composed of approximately 50% silica and 10% calcium oxide with lesser contents of potash and soda. Commonly found across North America and known by a variety of different nicknames, from "lava rock" to "cinder stone," the two types of stones are formed when gas is trapped within lava as it cools – leading to a porous appearance. Then these gas bubbles tend to rapidly exsolve.
1. Scoria differs from pumice, another vesicular volcanic rock, in having larger vesicles and thicker vesicle walls, and hence is denser. Scoria-fall deposits-- These are derived from Strombolian eruptions of scoria cones. The vascular structure of scoria arises due to the release of gases that are dissolved in magma when magma comes out of a volcano during an eruption. It is an extremely vesicular basaltic lava with very small (< 1mm) vesicles. Pumice is also formed as a result of a volcanic eruption, but the eruptions that cause this white or light-grey stone are far more violent and explosive than those that create scoriac stones.

Scoria forms from basaltic magmas, while pumice forms from rhyolitic magmas - which usually contain more gas. Perlite vs. Pumice. However, pumice is less dense than scoria rock. Some will be denser and less porous which means it won't aerate as well. When the magma breaks through to the Earth’s surface and becomes lava, the change in pressure causes the gas, which hasn’t dissolved as it does when scoria forms, to bubble up to the surface and form an almost frothy, foamy top to lava flows. Scoria usually holds a little less water than pumice, but more than perlite. Scoria and Pumice. This contrasts with pumice stone, which holds slightly different properties. Typically, pumice is light coloured; e.g. by Kathy Derrick and Jac Jenkins | Mar 30, 2020.
