Gold And Gold Tarnishing
Gold ornaments have their significant part in Indian culture and tradition to follow. Indian culture cherishes the importance of wearing gold jewellery, for it adds prosperity and wealth to an Indian family. Women adorned with gold jewellery are considered as symbols of wealth and richness of the family. So, maximum care is taken to maintain those gold ornaments not to lose its shine and lustre. Tarnishing is corrosion of the surface of the gold ornaments. Tarnishing doesn’t affect pure gold.
Tarnishing may be seen in gold ornaments made of lower carat gold, i.e., eight to ten-carat gold where the content of gold is 75% or less. Tarnishing can be caused by the presence of sulphur compounds in the air. Perspiration or sweat is also one of the common causes of tarnishing. Deodorant sprays or perfume may also induce tarnishing in gold ornaments. Acidic food items can also cause gold tarnishing.
