Brass engraving craftsman, Cairo Egypt - July 1981
Brass is an alloy composed of copper and zinc, usually for sheet metal, and casting in the proportion of seven parts of the former to three of the latter. Such a combination secures a good, brilliant colour. There are, however, varieties of tone ranging from a pale lemon colour to a deep golden brown, which depends upon a smaller or greater amount of zinc. In early times this metal seems to have been sparingly employed, but from the Middle Ages onward the industry in brass was a very important one, carried out on a vast scale and applied in widely different directions.

The Egyptian Knowledge of Metallurgy and Metalworking
The Egyptians learned how to work metals from an early period, and all agree that 5,000 years ago, the Ancient Egyptians had already developed the techniques of mining, refining, and metalworking.
Ancient Egypt did not have several kinds of mineral ores, such as silver, copper, tin, lead, etc., even though they produced large quantities of electrum (an alloy of gold and silver), copper, and bronze alloys. The Ancient Egyptians used their expertise to explore for mineral ores in Egypt and in other countries. Ancient Egypt had the means and knowledge to explore for needed mineral ores, establish mining processes, and transport heavy loads for long distances by land and sea.
Because it being was largest and richest population in the ancient world, Egypt imported huge quantities of raw materials; and in return exported large quantities of finished goods. The Ancient Egyptians’ finished metallic and non-metallic products are found in tombs throughout the Mediterranean Basin, European, Asiatic and African countries.
The Egyptians possessed considerable knowledge of chemistry and the use of metallic oxides, as manifested in their ability to produce glass and porcelain in a variety of natural colours. The Ancient Egyptians also produced beautiful colours from copper, which reflects their knowledge of the composition of various metals, and the knowledge of the effects produced on different substances by the Earth’s salts. This concurs with our “modern” definition of the subjects of chemistry and metallurgy.
