All About Salt 
Salt - the simple, elegant marriage of a sodium ion with a chloride ion - is one of the most basic and essential molecules on earth. Salt is the only rock we eat. It's a food preservative, flavor enhancer, bioregulator, and a building block for more complex chemicals. As a form of currency in the ancient world, salt has, at times, been worth its weight in gold.
Salt is comprised of 40 percent sodium and 60 percent chloride by weight. Salt crystals are perfect cubes, which is one of the key reasons that salt is so pure: very few elements can interfere with the symmetrical, tightly bound atoms that comprise a salt crystal.
How pure is salt? After the harvest and an initial rinse in saturated brine, our salt is 99.5 percent pure. Most of the 0.5 percent impurity is water - the rest is mostly dust from the air. Both are removed in our refining process.
