Obsidian, igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. Obsidian is extremely rich in silica (about 65 to 80 percent), is low in water, and has a chemical composition similar to rhyolite. Obsidian has a glassy lustre and is slightly harder than window glass. Runes are used in divination and charms. They have been used since the ancient times for these purposes. You might not know where to start when it comes to knowing how to use magick runes. It does take a little getting used to to seamlessly incorporate them in your magical workings. Black Obsidian Rune Sets are available at Matural Agate. Book your order now.
