Bests & Worsts Reviews from Amazon

I was really excited to get this salt. I've been using another brand and decided to try this one out, big mistake. I filled up my salt mill and made some chili. While eating it felt like we were eating sand. So i got about a cup of the salt and sorted through it. Put the pieces that didn't look like the rest in water. I left those pieces in the water for around 3 hours and they did not dissolve So what ever those pieces are, they are not salt. Also while sorting I found another foreign object. Looks similar to a piece of skin? I am not quite sure what it is. I can't recommend this product. Update: I continued to sort through the salt and found many small white pieces. I tried one and it was extremely bitter. Maybe limestone? I updated the photos and added a picture of the white pieces.
