Paracelsian chemistry of the 1500s introduced salt as a third principle which embodied the other two, mercury and sulphur; salt was that universal mediating presence which represented earth. By the late 1700s salt was no longer a metaphysical principle but an acid-base compound, and volatile salts aroused most interest.
