No, Morton Coarse Sea Salt is not iodized. It is pure sea salt with no additives, including iodine. This makes it a suitable option for saline solutions for piercings, as recommended by many piercers. Always check the ingredient list to confirm.
Morton coarse sea salt has an indefinite shelf life when stored properly. As a mineral, it does not spoil or go bad. However, it's best to keep it in a cool, dry place in an airtight container to prevent moisture absorption, which can cause clumping. While it won't expire, maintaining proper storage ensures its texture and ease of use over time.
