Salt crystals

Salt crystals

This large lump of salt crystals (about 30 centimetres across) clearly shows the cubic shapes that salt forms when it precipitates out of sea water. It was grown at Lake Grassmere for display purposes. Humans and other animals naturally crave salt, and it has a distinctive taste that makes it invaluable in cuisine. This, however, is not its major use. Salt is used mostly in industries such as paper making, where it is needed for the production of chlorine and caustic soda.
