Difference between Raw Salt and Rock Salt

Raw salt and Rock salt are of different color and the size of crystals. Rock salt forms in large crystals whereas raw salt crystals are comparatively small in size. The large crystal size of rock salt means it usually takes long to dissolve in water.

Rock salt are the remains of inland seas which evaporated thousands of years ago.

In contrast, raw salt is harvested from evaporation ponds which remove salt from seawater.

There is not much difference in  the composition of the two salts.
