Jiang Feng was calculating carefully, but he quickly crossed out 500 kilograms of salt again. The reason for the slow efficiency in the early stage was because the salt field was being built in the early stage, which slowed down the overall efficiency. If we simply consider that after the salt field is completed, In order to improve the efficiency, Jiang Feng quickly recalculated a number. The average daily salt production rate of a person is about 750 kilograms.
Based on this efficiency calculation, if we add several times more manpower, it should not be difficult at all to reach an output of 120,000 stones per year, because the salt production rate will definitely drop to an extremely low number in winter, so production must be increased in summer and autumn. , I just don’t know if this salt lake... can sustain such development.
Of course, Jiang Feng didn't know that the entire salt lake would be able to supply the entire Tang Dynasty for more than a thousand years. Of course, the Tang Dynasty couldn't rely on just this one salt lake to supplement its supply.
In fact, there are many salt lakes in Qinghai, but unfortunately you can eat the salt directly from the sun, which is a Chaka, such as the Chaka Salt Lake in later generations, which is larger than Chaka, but the Chaka Salt Lake is famous for its potassium salt, that thing An important source of fertilizer and industrial salt, rather than table salt.
What Jiang Feng has to consider now is not just the brine. He is also thinking about how to improve the brine and filter out the impurities in it to produce better quality salt. His Highness said that he will teach them systematically what chemistry is in a while. , can be used to study the extraction of table salt.
During this period, Jiang Feng got a lot of information from the working Tuguhun nobles. For example, the Tuguhun nobles had always known about the salt in the Red Sea, but they had blocked the news. In some places in the Red Sea, only Uncover the salt cover on top, and the salt dug out from below will be free of impurities.
Moreover, Jiang Feng also heard that the salt here was sold to the Central Plains during the Han Dynasty, but it gradually stopped selling.
Jiang Feng knew about the salt caps in these people's mouths. Because the salt caps contain impurities, they are not as pure as the salt below.
The question is, why is the salt cap formed by the constant solidification of salt lake water, the upper salt cap has more impurities, but the salt below is purer? What's the truth in this? If this is clarified, is it possible to filter out impurities as His Highness said? How to simulate this environment?
And why does the salt made according to the method given by His Highness not have as many impurities as the naturally condensed salt caps?
Jiang Feng, who was originally calculating efficiency, couldn't help but fall into thinking again.
While Jiang Feng was thinking, Iron Hammer was also struggling. He first exchanged five kilograms of black noodles, which are thick noodles processed directly from wheat without removing the bran. This kind of face was a luxury for them before. I can’t even eat it once during the Chinese New Year.
But now he can earn 5 pounds for one day's work! Enough food for their family for a day! If his eldest son's is included, this means that they can save one day of rations for every day of work! Wouldn’t it be possible to save a year’s worth of food in one year? ! Then they can have the luxury of killing a sheep during the Chinese New Year!
And in the grain store, Iron Hammer actually saw snow-white noodles! White flour without gluten! 2 pounds of food stamps can be exchanged for 1 pound!
And salt! There is salt in the Red Sea, and Iron Hammer knows it, but it is not something they can get involved in. It used to belong to the nobles! But now His Highness has spent a lot of effort to make these salts, but only 5 kilograms of grain can be exchanged for half a kilogram!
What a gift!
What's more important is that after Iron Hammer came here, they discovered that His Highness had opened up to them more than just salt and food! They can also exchange them for fish, and fish is very cheap. One pound of food stamps can be exchanged for one pound of fish!
What’s more, at the third store, Iron Hammer could hardly believe his eyes! iron! That's right! His Highness is actually willing to let them exchange for iron tools!
When he saw the iron weapons, Tie Hammer was shocked, because even an ordinary herdsman in the Tang Dynasty knew how the Tang Dynasty banned iron weapons in countries like theirs! Among herdsmen, a knife can be used as a family heirloom! And the arrowheads they use for hunting are almost all made of wood! The Hammer family has a small knife, which was passed down from his grandfather's time!
But over the years, the knife has become smaller and smaller!
And now, His Highness actually asked them to exchange food stamps for it! Tie Hammer went to see the exchange price for ironware. It was also calculated based on weight. If you want to exchange for ironware, 1 catty of pig iron can be exchanged for 50 catties of food stamps!
Tie Shui was moved to tears. His Highness’ price for a kitchen knife was 70 kilograms of food stamps, which meant that he could exchange it for a kitchen knife after working for more than two months! This is something I never dared to think about before! In the past, let alone two months, he worked for a nobleman for a year, and the nobleman would not even give him an iron kitchen knife!
Their family had only one iron dagger that had been passed down for three generations, and now it was almost as worn as a knife.
Tie Hammer couldn't help but think, it is said that the cost of making iron is very high, can His Highness afford the loss? Give them such a low price.
Lu Hai is also calculating this problem. A blast furnace requires about 80 people to maintain. Among them, only 20 people are needed to operate the blast furnace in two shifts. The remaining 60 people are used to dig iron ore, coal mines, and transport iron. Mine coal consumption.
The work of about 80 people can supply a blast furnace. Mainly they mine the rich iron ore according to the information given by His Highness. About 1.8 stones of iron ore produce 1 stone of pig iron.
In fact, manpower is mainly consumed in transportation. Coal mines, iron mines, limestone mines, and copper mines have been tried to select the closest ones based on the information given by His Highness.
Lu Hai is considering whether to prioritize building concrete roads between these mining areas so that they can move faster and require less manpower.
Nowadays, the amount of iron produced in one furnace is also increasing. On average, a blast furnace has three furnaces of iron per day. About 100 kilograms of iron are produced per person per day. If one person can exchange 1 kilogram of pig iron for 10 days of work, the profit will be approximately 999 times.
However, this profit is only here in Xizhou. If it is transported to Chang'an or other places, this profit will definitely be reduced.
Lu Hai was a little confused about how he could help His Highness increase profits. He heard that His Highness was going to prepare a dowry for His Highness Changle. The eldest grandson's family seemed to be quite wealthy. He didn't know if he could earn so much money in a year. He couldn't let His Highness do it anyway. lose!
Oops, no! Lu Hai suddenly knocked on his head, so stupid! So stupid! His Highness’s teachings have all been forgotten in my mind! Why should I calculate shipping costs? ! If I transport the pig iron from here to places like Longyou Road, can't I just pay the big buyers plus transportation fees according to His Highness's pricing? ! The cost of shipping a pound is 5 cents, I will add 10 cents!
It's so far away, so it's reasonable for the ironware to be more expensive! What's more, even if I add the transportation fee, it's much cheaper than them refining it themselves!
According to His Highness's teachings, this is called a seller's market! Yes, shipping fees must be added! Anyway, those who make large-scale purchases for the time being are aristocratic families, and they are not short of money.
As for ordinary people, they only buy one or two pieces, and the shipping costs are subsidized to the people according to His Highness’s pricing! Someone must tell them then, so that these people know that His Highness lost money on transportation fees just to sell them ironware at a low price so that they can use good ironware! Just do it!
By the way, when these herdsmen exchanged ironware, they had to tell them that the ironware purchased by the people in Chang'an City was slightly more expensive than them. In Xizhou, His Highness was sympathetic to them!
