Why are table salt crystals of uniform size? If you grow crystals, their size is all over the map, so how is this uniformity achieved commercially? Sieves?
See Scientist/Imagemakers for a picture of table salt crystals magnified 35x. You can see that the sizes of the crystals vary, even after sieving.
