scoria
noun (Concise Encyclopedia)Heavy, dark, glassy igneous rock that contains many bubblelike cavities. Foamlike scoria, in which the bubbles are very thin shells of solidified basaltic magma, occurs as a product of explosive eruptions (as on Hawaii) and as frothy crusts on some lavas. Other scoria, sometimes called volcanic cinder, resembles clinkers, or cinders from a coal furnace.
