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 | |
