Scoria can be obtained by smelting Soul Sand in a Furnace or by Bulk Blasting. Since scoria is usually basaltic in composition, it may come as no surprise that it is fairly common to find it in basaltic lava flows. It is formed in basaltic magmas, which means that it comes from lava that is flowing. Mineralogical examination of this material showed it to be typical of scoria found on basaltic cinder cones.

Comparisons: Scoria differs from pumice, another vesicular volcanic rock, in having larger vesicles and thicker vesicle walls, and hence is denser. If it has a coarse-grained, porous texture, it will have a dull luster. The magma is thrown into the air (or water, if its in the ocean) where it is suddenly no longer pressurized. The volcanic area, called a cinder cone or a scoria cone, is easy to mine, Bratton said. By definition, pumice has a specific gravity of less than 1 and will float in water.

Basaltic magma has a much lower viscosity, allowing for the gas bubbles to move about more freely and join together into larger bubbles. It occurs when minerals with a higher melt point have time to crystallize in the magma before it erupts to the surface and the entire melt rapidly crystallizes around them. The gas often blows out small bodies of magma that solidify as they fly through the air. Scoria typically has a lower density than other types of rocks, which can make it ideal for use in construction projects where a lighter material is desired.
