Salt

There are several ways that put back table table brininess has helped to skeleton the modern world. How season was extracted and touch on was perhaps the most influential. salinity was a valuable trade good and the methods in which it was gathered varied from country to country. As the geezerhood progressed, these methods evolved leading to how common salt is harvested today. In China, they started by harvesting salt in the summer when Lake Yuncheng modify up, the square crystals of salt were harvested on the surface of the piddle, this method became cognise as the dragging and conference method. The earliest record of salt production dates around 800 B.C. in China, and the Chinese seetheed ocean water in body pottery until it was reduced to pots of salt crystals; later, this method was spread throughout Europe as well. Then, in 1000 B.C. they boiled drench in iron pots to arouse salt because they found that the commove was better retained in them. To tap salt from mines, mine workers used bamboo tubes with that were insulated with mud & brine.

The salt was extracted through a extensive bamboo tube that fit quite a little the prick and at the bottom of the tube was a strap valve that would be forced shut by the weight of the water while the tube was hauled out; then the tube was held all oer a tank & poked so the valve would open and the brine would come across into the tank; tank was connected to bamboo piping that lead to the boil house. The boiling houses were open sheds where pots of brine cooked until the water evaporated and left salt crystals. Originally, t hese pots were heated by burning wood; howev! er, by deuce hundred A.D., boiling houses had iron pots heated by muck up flames. This was the setoff known instance of the use of natural natural gas in the world. The workers that used these piping systems learned to drill and shoring up up a narrow shaft, which allowed them to go deeper. Bamboo piping was a dear(p) candidate for the piping because it was salt resistant and the salt kills alga & microbes that caused rot and led to bamboo plumbing in homes that was...If you want to pay off a full essay, order it on our website: OrderCustomPaper.com
