Black bronze is a semiprecious alloy of copper, gold and silver. Unlike regular or bismuth bronze, black bronze cannot be used to create weapons or armor, restricting its uses to blacksmithing and metalcrafting purposes. Black bronze cannot be smelted directly from ore, but only from bars of pure metals. Unlike some alloys, the value of a bar of black bronze is equal exactly to the average value of its components – creating this alloy does not increase the total value of the material (2 copper bars at 10☼ each + 1 silver bar at 50☼ + 1 gold bar at 150☼ = 220☼/4 bars = 55☼/bar of black bronze).

In real life[edit]
The actual composition and process of creating black Corinthian bronze has been lost to history, noted by the Roman author Pliny the Elder (AD 23/24 – AD 79), as is typical of closely guarded trade secrets of pre-industrial society. In Japan, a similar alloy of copper with gold, known as Shakudō, was somewhat commonly used for decoration of luxury metal goods. Unlike the ancient Greek metal, however, this "black bronze" was never lost and is still produced in small quantities today.
