Table salt & Kosher salt (table salt that has been blessed by a Rabbi) are the refined form of Sodium Chloride. Because this salt is highly refined, iodine & anti-clumping agents are often added. This processed salt is great for general, all-around use. Like all salt, it possesses cleansing & purifying properties. It is inexpensive & is a great choice if you are just starting out, if you're are on a tight budget, or if you need a large quantity of salt.
