The 'Uroboros' is an alchemist's term often represented by a dragon or serpent devouring its own tail. The ancient symbol represents an endless cycle of renewal or life everlasting. The name honors the traditions and lore of medieval alchemists as they struggled to turn non-precious lead into precious gold. Today, Uroboros uses non-precious sand to make some of the most precious hand-cast art glass available in the world.
