Our story today comes from the marketing department. In the early 1900’s Morton’s added magnesium carbonate to their salt. This prevented the little granules from sticking together so that you didn’t end up with clumps in your salt shaker. The sweet girl with the umbrella, yep, she is advertising chemicals added to your salt. They now use calcium silicate.
To illustrate the point of the free-flowing salt, the marketing department came up with the saying “When it rains, it pours”. It had no intention of meaning that when things are going wrong, they are really going wrong – but it has adopted that meaning.
