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.
Another economically important type of rock salt deposit is the salt domes, which were formed when earth pressure forced up plugs of rock salt measuring approximately a mile across. The domes appear to result from pressure, which pushes the salt up through the rocks from depths as great as 50,000 feet (15,000 metres).
