Sea salt crystals. Coloured scanning electron micrograph (SEM) of crystals of sea salt (a form of the mineral sodium chloride,NaCl). Sea salt is a coarse (large-grained) type formed naturally by the evaporation of sea water. Unlike other types of salt,it contains traces of elements like zinc,magnesium,iron,calcium,potassium,manganese and iodine. This gives sea salts a distinctive taste. The size of the crystals can be changed by grinding to obtain fine-grained varieties from the coarse varieties. Magnification: x115 when printed 10cm wide | |
