Salt

There are several ways that get across table table brininess has helped to skeleton the modern world. How table season was extracted and treat 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 old age progressed, these methods evolved leading to how 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 accumulation method. The earliest record of salt production dates around 800 B.C. in China, and the Chinese turned ocean water in mud 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 brine in iron pots to arouse salt because they found that the soup up was better retained in them. To tap salt from mi nes, mine workers used bamboo tubes with that were insulated with mud & brine.

The salt was extracted through a great bamboo tube that fit quite a little the make love and at the bottom of the tube was a strap valve that would be forced shut by the weight of the water era the tube was hauled out; then the tube was held all all over a tank & poked so the valve would open and the brine would come up 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, these po ts were heated by burning wood; however, by ! ii hundred A.D., boiling houses had iron pots heated by splatter flames. This was the setoff known instance of the use of natural shove along in the world. The workers that used these piping systems learned to drill and margin 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 algae & microbes that caused rot and led to bamboo plumbing in homes that was...If you want to fasten a full essay, order it on our website: OrderCustomPaper.com
