Modern Marvels - Salt Mines

Seizoen: 8 - Aflevering: 53 / 236 - Eerst uitgezonden: 05 december 2002 - Episode ID: 414510

It's in our blood, sweat, and tears. Join us as we dig up salt mining's history--from the "white gold" on the table to the oceanic and underground deposits whence it came. Though today we take salt for granted, most life depends on it. Roman soldiers were sometimes paid in it--hence the word salary. And many slaves died procuring it.
