Obsidian, Showing Conchoidal Fracture

Fracture describes the way a mineral breaks when it does not display cleavage, the tendency to split along specific planes. Fracture is described with terms such as hackly, even, uneven, fibrous, splintery, etc. Conchoidal fracture resembles the curved lines of a clamshell, and is characteristic of the way glass breaks. Obsidian fractures this way because it is volcanic glass.
