Morton Salt Company was now both a distributor and a producer. One of its early innovations, in 1911, was the addition of magnesium carbonate to table salt, which kept the salt crystals from sticking together; as stated on the box, the salt “never cakes or hardens.” Eventually, the chemical was replaced with another nonsticking agent, calcium silicate. This nonsticking quality was to become the basis of Morton’s famous marketing campaign. Another innovation: In 1924, on the recommendation of the Michigan Medical Association, Morton produced the first iodized salt.
