The black, newly solidified glassy surface of pahoehoe lava flows commonly has a silvery or iridescent color. Pahoehoe lavas form during eruptions that are characterized by the upwelling of hot, low-viscosity magma. This smooth-textured pahoehoe flow at Kīlauea volcano was photographed in August 1994.
