Ancient Egyptian Metallurgy
During the early Predynastic Period, (about 5000 B.C.) ancient Egyptians discovered copper, gold, silver and lead. Later on, they discovered iron, tin, bronze and brass. They were well acquainted with metallurgical processes such as smelting, annealing, alloying, reduction, and established techniques of mining, refining and metalworking. Ancient Egyptians had the technology and knowledge to investigate and discover the mineral ores that they needed and transport substantial loads for long distances through land and sea. Their extensive understanding of chemistry also enabled them to produce glass and porcelain, as well as finished metals, in a range of natural colours.
