The difference between sea salt and well salt
1, different sources, sea salt: sea water as raw material. Well salt: natural brine and rock salt deposits collected from deep wells below 1,000 meters.
2. The processing difficulty is different. Sea salt: The main components before processing are NaCl, MgCl2, CaCl2, etc. In addition, there are a large number of microorganisms and other trace elements, and their processing methods mainly rely on sun drying and purification. Well salt: before processing, the main components are Ca(HCO3)2, CaCO3, NaCl, MgCl2, CaCl2, Na2CO3, NaNO3 and NaNO2, as well as a small amount of microorganisms and other trace elements. Compared with the natural composition of sea salt, the composition of well salt is complex and changeable, and it is troublesome to process and manufacture, so it needs to be refined by fully sealed vacuum process.
3. Sea salt with different colors: Sea salt from different places contains different trace elements, which will produce different colors, such as tan, taupe, reddish and dark white. Well salt: its color is generally white.
