The use of gold traces its history back 6000 years. High luster, yellow and white color, resistance, reflection, malleability, being ductile, gold is perfect for ornamental purposes. Jewelry consumed up to 80% of gold produced in the world. Pure gold is too soft and can bear high stresses. A 'karatage' standard was developed to indicate the purity of extracted gold. A 24k gold is nearest to the pure whereas 10k indicates the lowest amount of gold content in a mixture.

Talking about the world of Electronics, gold plays a vital role. This is because, gold is the best conductor of electricity and have minimum resistance resulting in very low heat and high speed of current flow. In addition, it remains free from corrosion. Gold connectors and connections among circuits are also considered as very reliable as compare to traditional copper.

The use of Gold in dentistry can be traced as back as 800 B.C. Filling using iron does not sound nor taste very good. In addition, Iron easily get corroded and continuously needed to be replaced. On the other hand, gold has a very high appeal and has superior performance over iron and it does not also corrode.

In aerospace, conventional copper connectors and paths for current flow are usually avoided and gold is preferred because billions of dollars project can be easily messed up if the electronic circuitry fails. Therefore, a highly reliable material is required and this requirement is fulfilled by gold for making connectors and connections in the electronic circuit.

Glass also consumes a portion of total gold production. A ruby color is produced when a small amount of gold is added in the liquid glass while manufacturing. In addition, glasses used in climate control buildings require gold to be plated or mixed in the glass.
These and numbers of other uses of gold can be listed and discussed. The future of gold is also as bright as gold itself. Increasing research and even more speed requirement of electron may require gold at a much higher scale as it currently is.
