Nature gives us many useful things. We cannot do without them. Salt is one of them. It is a necessary article in food.
Salt is obtained from the sea. It is also obtained from mines. The latter is called rock-salt. There are famous salt mines in the salt ranges in Punjab and Rajasthan. The rock salt is dug out from mines. It has a reddish colour. To obtain salt from the sea water, we have to boil the water or let it evaporate in the sun. When the water evaporates, salt is left behind. This salt is not pure. It is purified afterwards. Pure salt is white in colour. In India, salt is prepared in a large quantity in coastal areas. Salt is also prepared at the Sambar Lake in Rajasthan.
