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 2☼ each + 1 silver bar at 10☼ + 1 gold bar at 30☼ = 44☼/4 bars = 11☼/bar of black bronze).
