Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock.
In the Stone Age, people used sharpened bone, flintknapped stones, flakes, and chips of rock as weapons and tools.
Such items remained in use throughout human civilization, with new materials used as time passed.
While pure Obsidian is dark in appearance, the colour varies depending on the presence of impurities.
Obsidian is commonly found within the margins of rhyolitic lava flows known as obsidian flows, where the chemical composition (high silica content) induces a high viscosity and polymerization degree of the lava.Those that have survived are usually made of stone, primarily consisting of flint, obsidian or chert.In many excavations, bone, wooden and metal arrowheads have also been found.An arrowhead is a tip, usually sharpened, added to an arrow to make it more deadly or to fulfill some special purpose.The earliest arrowheads were made of stone and of organic materials; as human civilization progressed other materials were used.
