In our society, gold is seen as a symbol of wealth. Most of the gold that we see around us is in the form of jewellery and other artefacts. But gold has more desirable qualities than its beauty which makes it a valuable metal in the industry.
The properties of gold make it vital for the manufacture of components used in a wide range of electronic products including computers, telephones, cellular phones, and home appliances. Gold is used for shielding satellites and spacecraft from solar radiation because it is an excellent reflector of heat.
Gold is a vital element in medical research; it is even used in the direct treatment of arthritis and some other diseases. Gold is also widely used in dentistry; though getting a gold tooth to replace a natural one is rather expensive!
In some Asian countries, gold is used in food and drink, from fruit jelly to coffee. Some sweets are covered with gold leaf.
