Before he knew it, he was signing a contract with Pie Town Productions for the new show. The couple would buy, fix up and flip 13 houses in 13 episodes. Although the El Moussas were paid $10,000 per episode, the money they used to buy the houses was from their past investments, Christina El Moussa said.
As the water from this sea evaporated, salt crystals formed from the brine, along with other useful minerals such as gypsum (used for wall plaster) and potash (used for fertiliser). Rock salt is mined at Winsford in Cheshire, Boulby in North Yorkshire and Carrickfergus in Northern Ireland.
All major rock salt deposits originated from the evaporation of seawater at some time during the geologic past. Approximately 78 percent of the mineral matter in normal seawater is sodium chloride. Upon evaporation of about nine-tenths of the volume of seawater, rock salt is precipitated. Calcium sulfate (gypsum and anhydrite) and potassium and magnesium salts also are precipitated.
