The ship sank about 2,600 years ago, around the first half of the 6th Century BC, and was found under 10 feet of water about 1000 feet off the coast near the port of Gela, where the ship was believed to be bound. Analysis of the ingots reveal that they are composed of roughly 75-80 percent copper and 15-20 percent zinc, with smaller percentages of nickel, lead and iron. Some scholars believe that Plato's orichalcum was a brass-like alloy composed of copper and zinc created by heating zinc ore, charcoal and copper metal in a crucible.
