THE PLACE
Salt with an address.
Cargill’s account of its Newark facility follows salt from San Francisco Bay water through concentrating ponds to harvest. This listing covers the Newark operation and its described pond process, not every Cargill salt plant or all historic Bay salt ponds. [1]
THE METHOD
How the salt is made.
Cargill describes pumping Bay water into ponds and moving increasingly concentrated brine between them. Sun and wind evaporate the water; crystals form in crystallisation ponds and machinery scrapes them from the floor. The company’s account explains a process that can take several years. [1]
Process described by the operator; method categories are editorial groupings. Not independently inspected.
