Sangue Inverso (III): Obsidiana (A)

Sangue Inverso is a piece of large duration divided in parts. The names for each part are inspired in mineral elements. All structural elements, from micro to macro, are based in ideas of symmetry.

Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It’s produced when lava extruded from a volcano cools rapidly with minimum crystal growth.
