1-2" Sulfur Volcanic Rock - 2 Pieces
It is typically defined by both its mineral content, and texture. It is called vesicular Basalt, Cinder, or Scoria, it may or may not contain crystals. The vesicles are formed as dissolved gases are exsolved, resulting in the formation of small, spheroids that open into one another. It looks like a dark version of pumice, another vesicular igneous rock, though vesicular Basalt has a higher specific gravity and will sink in water.
