Description

Salt. Diascopic light micrograph using Normarski Interference Contrast (DIC) of a crystal of sodium chloride, the common salt. This is a white crystalline compound widespread in nature as a solid (rock salt), around margins of salt lakes and in solution (about 3%) in seawater. Other metals are present in the raw material such as calcium, iron and magnesium. These are often removed by precipitation before the salt is sold. Salt is used as a food seasoning and preservative, and as a raw material in industrial processes such as in glass and soap making. Object size: 2.5 mm.
