Obsidian- a bit of history
The name obsidian was put into use as early as 320 BC. It was first used by Theophrastus, a Greek philosopher of nature. The origin of the name is attributed to the Obsius tribe, who once inhabited the territory of present-day Ethiopia. The second theory is that the name comes from Obisius, who was supposed to be a Roman discoverer of volcanic glass.
Dragon glass gives very sharp and hard edges so it was a good material for tools. Already the oldest human culture used it to make weapons and tools. In Mesopotamia, additionally, sculptures and ornaments were made of it, and the Maya and Aztecs even made mirrors of it.
Nowadays, obsidian is mainly used in sculpture and jewelry. Thanks to unusual light effects, beautiful jewelry is made of obsidian. Obsidian beads are relatively inexpensive and have an exclusive appearance. Volcanic glass jewelery should only be cleaned with lukewarm water.
