MEMBER REVIEW: This is a History Channel Production. It has a bit of the history of salt (but nothing of ancient history - I recommend the book "Salt" by Mark Kurlansky for that. Stay away from "Neptunes Gift" - boring as hell.), and salt mining with emphasis on medieval to mostly modern salt mines. It is interesting, and shows the ways salt is mined today: in mines, and by evaporation and brining. They also detail the salt mine in Poland with the cathedral and other beautiful carvings. There are even chandeliers with salt crystals. It plays a bit like an industrial film, but for people interested in the strategic uses of salt, it is pretty good. There is very little geology, though. And lots of Cargill people talking about the wonders of salt. I was somewhat bemused by the guy who said he could stare endlessly at a pile of salt. That is dedication to his work. He works at the evaporation plant near San Francisco. A DVD worth watching, but not one I want to save and treasure.
