I think that I would be the best judge of what defeats my purpose that I described.
I wanted to store 100 pounds of salt in two solid blocks that were easy to store in one place and in little space, at a cost that was close to free, $13.00. as a kind of deep storage bonus on top of what I already thought an adequate amount of survival granulated salt.
Buying 25 separate bricks at a cost of $50.00 was not what I was looking for. I really like the idea of 50 pound blocks, even an apartment dweller could store one of those easily.
I can already buy 1 pound containers of table salt at the store for 39 cents. I also already buy the 4 pound boxes of canning salt at the supermarket at a cheap price.
As I said, knock yourself out.
