The Pharaohs of ancient Egypt likely recognized that gold is resistant to corrosion and thus used it in fashioning their death masks. Testifying to gold’s durability, when archaeologists uncovered the tomb of Pharaoh Tutankhamen thousands of years after his death, the young king’s golden death masks was found to be untarnished and still a lustrous yellow color.
Gold retains its luster because water and air—the destroyers of other metals, such as iron—don’t affect it. This resistance to corrosion combined with gold’s outstanding ability to conduct electricity makes it ideal for use in electronic components. Each year about 200 tons of gold goes into the manufacture of TVs, VCRs, cell phones, and some 50 million computers. In addition, high-quality compact discs contain a thin layer of durable gold to ensure dependable data storage.
Thin films of gold display some unusual characteristics. Consider the metal’s interaction with light. When processed into ultra-thin sheets, gold becomes transparent. At this thickness, it allows green light waves to pass through but reflects infrared light. Windows coated with gold admit light but reflect heat. Thus, the cockpit windows of modern aircraft are coated with gold, as are the windows of many new office buildings. Also, nontransparent gold foil is wrapped around the vulnerable parts of space vehicles, effectively protecting them from intense radiation and heat.
Gold is also highly resistant to bacteria. Hence, dentists use it to repair or replace damaged or decayed teeth. In recent years gold has proved to be an ideal material for use in surgical implants such as stents—little wire tubes inserted inside the body to reinforce damaged veins or arteries.
Given gold’s versatility, value, and beauty, prospectors will no doubt continue to scour the
earth for this appealing metal.
