14 Unexpected Uses For Salt

From Networx's Katie Marx:

Salt is an extremely abundant mineral. You might think of it primarily as that thing on the dinner table you use to add some flavor to your food, and it's certainly useful for that, but the uses of salt extend far beyond that; there's a reason the Romans prized it so much that soldiers were paid in it. (Well, also, salt was harder to extract for the Romans, so it was worth a lot more.)
