Geology
Himalayan Pink Salt
← All Exhibits
This rock salt gets its pink color from trace minerals like iron oxide trapped inside it — deposited millions of years ago when an ancient sea evaporated and left its dissolved salt behind as solid rock.
Additional Information
Most of the world’s pink rock salt is mined from ancient seabeds, particularly in the foothills of the Himalayas.
The pink color comes mainly from trace amounts of iron oxide and other minerals mixed in with the salt, not from the salt itself.
Chemically, rock salt is mostly the same sodium chloride as ordinary table salt — the color and trace minerals are really the only difference.
