Bronze

Ancient Sumerians used copper- and tin-rich rocks to build campfire rings. As the stones became heated, the metals melted and mixed forming this world-changing metal. Bronze brought tools, weapons, armor, building materials, and a new sense of value to the ancient world. It is often associated with fire because of its reddish color. An alloy of copper and tin, bronze takes on the properties of both but is generally thought to enhance courage and practicality and encourage focus on work. It is also thought to be good luck for warriors.
