Obsidian is an extreme variety of igneous rock with a glassy texture. Most popular accounts say that obsidian forms when lava cools very quickly, but that is not quite accurate. Obsidian starts with lava very high in silica more than about 70 percent , such as rhyolite. The many strong chemical bonds between silicon and oxygen make such lava very viscous, but equally important is that the temperature range between fully liquid and fully solid is very small. Thus, obsidian does not need to cool especially fast because it solidifies especially quickly. Another factor is that low water content may inhibit crystallization.

Obsidian flows develop a blocky surface as their outer shell quickly solidifies. Obsidian may display complex folding and segregation of minerals in bands and round masses consisting of feldspar or cristobalite high-temperature quartz.

Obsidian is a natural volcanic glass : it is a kind of igneous rock. It is produced when lava high in silica SiO 2 cools rapidly, and solidifies quickly. They were used as arrowheads , and today they may be used as surgical scalpel blades. Obsidian is mineral -like, but not crystalline. It is dark in color like basalt. Obsidian does not last forever. It is metastable : it changes very slowly.
