Flake Salt
Flake Salt is still another type of salt used in cooking and in bath salts. Flake salt, as its name suggests, is a mound of flakes, as you would think shaves of soap to look like. Flake salt is a type that will melt quickly into the bath waters. Flake salt is not common as other types of salt listed, but it is easily found and quite useful for the bath salts you want to enjoy in the shower.
You can use flake salt in the shower because it melts quickly but you still get the effects of the salt as it runs over your body in the water. Flake salt come from the sea, dried from the water by the sun and then baked to create the small flake like crystals that you see when you purchase this type of salt.
