Plain Gold
Gold is a precious metal, occurring in deposits of alluvial soil, veins and rocks in natural form. The mined gold is extracted and refined industrially by chemical processes.
The consumption rates of gold are the highest in jewellery making, amounting to almost 50%, due to its ductile and malleable nature. It can be spread into sheets and drawn into long wires. Pure Gold can be used as such and is widely used to produce Gold coins and bars. Gold alloyed with other metals like Copper, Silver, Zinc and Platinum find its use in jewellery making as it is hard in texture.
Gold is categorised into different types based on its Karat, colour and coatings.
The fineness of the quality of gold is defined in terms of Karats. Pure gold is 99.96% pure, containing 99.96% gold and is designated as 24k. This is soft and can be easily moulded, but will not withstand the wear and tear caused by constant use. Hence it is mixed with Copper to yield 22k gold, which is utilised for making plain Gold jewellery. This contains only 91.6% gold making it much more durable. Since plain Gold is not sufficiently hard to hold diamonds and stones, it cannot make studded jewellery. The jewellery should bear the Karat mark, which indicates the level of purity of the ornament.
The colour of the pure Gold and alloyed with other metals is reddish yellow and non-yellow(grey or white ). The Gold colour will decrease with the amount of alloying done, making 22k plain Gold bright golden in colour.Plain gold is widely used in the production of gold leaves where the gold is beaten into thin sheets or gilded and wrapped around the metal. This is widely used to decorate picture frames holding paintings, statues, food and drinks, etc., which creates an aura of luxury.
