What is Scoria? Scoria is a dark-colored igneous rock with abundant round bubble-like cavities known as vesicl It ranges in color from black or dark gray to deep reddish brown Scoria usually has a composition similar to basalt, but it can also have a composition similar to andesite Many people believe that small pieces of scoria look like the ash produced in a coal furnace
