Scrying is a technique of divination , of producing visions, perhaps of the future, through a prol  nged gaze. Scrying was famously practiced by the 16th century astronomer, mathematician and alchemist John Dee with the assistance of presumed impostor Edward Kelley, using a black obsidian mirror.

With its glassy luster, obsidian is a distinctive stone. Obsidian is formed as lava from volcanic eruptions cools within the earth. The speed at which it cools prevents crystallization and the rock forms as solid volcanic glass.

Although its most common colour is black, obsidian can also be found in light brown, brown mottled with black, and black with a beautiful golden or silvery sheen.Obsidian was revered by ancient cultures. It was one of the major barter materials, and prized for its ability to be worked to razor-sharp edges for arrows and spears. It has been used since prehistoric times for making tools, masks, weapons, mirrors and jewellry.
