Questions about table salt

I am doing a project on table salt... help!

Try the following link(s).

Salt (Mrbloch Archive) (David Bloch)
The natural history of salt, including sections on salt physiology, geology, archaeology, palaeoclimatology, production, influences in religion and economics, uses of salt, and more.

What is Salt? (The Salt Institute)
Frequently asked questions about salt, including information about chemical and physical properties, structure, toxicity, industrial uses, mining, and manufacture.
http://www.saltinstitute.org/15.html (12/04/98, 12/17/99)

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?
garicao, 10/24/99

Larger crystals are crushed; the cleavage lines are at right angles and the fragments are roughly cubic. Crushing results in a distribution of sizes so the salt is sieved to obtain uniform particle size.

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.
