The only iodized salt brand I use. A little goes a long ways so this lasts forever! You can purchase at almost and grocery store and it's a great value too. I recommend this to anyone who can have salt.
I actually use this kind of salt to clean my glass pieces. A little 70% isopropyl alcohol and some rock salt is the best way to loosen materials that may stick to the sides of the glass. I sometimes cook with it, especially stuff i'm boiling
