Chapter 35 Industrial Layout

Cheng Wenying said with a smile: "Then please Mr. Zhang hurry up and draw up a Chen, ah no, why don't I also transfer two capable shopkeepers here to jointly prepare them, and by the way, they will each make a new account book for the two families." ”

"If you encounter a problem in the middle, you will come to consult the virtuous nephew again, and after making sure that everything is safe, Mr. Zhang will send this method to the imperial court."

Shopkeeper Zhang arched his hand and said: "It's still too public and meticulous, so it's appropriate." ”

After the matter was arranged, Su You could finally get out and go to the blacksmith shop.

When he came to the blacksmith shop, Shi Tong's movements were really fast, and it was estimated that he and the tax supervisor were also in a nest of snakes and rats, and the green alum was already ready.

The ingredient of green alum is ferrous sulfate crystals heptahydrate, which is ground into powder and distilled with vinegar, which will obtain a taste of traditional Chinese medicine and pungent gas.

The thing that is condensed by this gas is called alum oil, which is actually sulfuric acid.

Su You tinkered with the experimental equipment here, and Shi Tong gave the ruler, triangle plate, vernier caliper, etc. over there to wax and carve out the scale.

The distillation equipment has a good effect, the ceramic stopper of the condenser tube and the mouth of the porcelain bottle have a similar effect to ground glass, as long as the taper fits, the sealing effect is very good.

The liquid and gas in the condenser tube enter a porcelain basin containing water, and soon, a small basin of sulfuric acid is made from the oil oil.

This pot is dilute sulfuric acid, mixed with some bile alum, that is, copper sulfate crystals, etching solution is ready.

After that, another pot was condensed, but this time salt was added to the alum, and the result was hydrochloric acid.

Hydrochloric acid is collected directly from the condenser tube and is concentrated.

With hydrochloric acid, lead skin, graphite, and soothonic oil, it has been able to make DC batteries.

Anything else may not work, but for etching, that's no problem at all.

Just do it, red copper has excellent ductility, let Shitong knock out two sections of copper wire, tie copper strips and graphite strips on the magnetic rod, as the anode and cathode of the lead-acid battery, one is connected to the measuring tool to be etched, and the other is connected to a piece of copper.

Dip the part that needs to be etched under the etching liquid surface, leave the rest on the liquid surface, light a fine incense, and lift it from time to time to see the etching effect.

Shi Tong was shocked by this series of operations, and prayed silently to the fine incense, and there were words in his mouth.

Su You rolled his eyes: "That's a timekeeping thing, it's not for you to pray to God and worship Buddha, if you have an hourglass, it's okay...... Gotcha, done! ”

The tools are washed, thrown into hot water and boiled to remove any wax, and a pair of shiny triangles are made.

Shi Tong shook his head at the triangle board and applauded again and again: "Divine skill! Master's magic skills! This rune is really delicate! It's not something that can be done by portrayal. ”

Su You couldn't help but complain again: "What rune, that's a number!" ”

Shi Tong didn't care: "Master, hurry up and get my set out!" ”

Su You said happily: "This set is yours, the experiment." Now that the process is formed, the next thing is mine. Hahahaha......"

After laughing, he said: "It's not over yet, I have to make an angle ruler next, I'll leave it to your guy in the store here, follow me to draw drawings." ”

The two masters and apprentices tinkered until dinnertime, and the ruler, triangle, protractor, and compass were all ready.

It is worth mentioning that the compass is the part where the two feet meet, the gear principle is used, the compass handle part is threaded, and the clamp that holds the compass foot and the pencil lead is also used for thread adjustment.

This is already Shitong's best craftsmanship, but the whole object is still a little large, the length of the compass has reached more than a foot, and the screw diameter is about three millimeters, compared with the fine threaded fittings of the compass in later generations, this compass is more like a quirky bicycle model.

It's good if it can be used, Su You comforted himself like this, but Shi Tong wrapped the full set of things in a precious way, and called the guy: "This set of things, hurry up and send it to the fourth master at home!" ”

When he was done, he had to pull Su You, saying that he wanted to give him a taste of good food.

Su You was greedy and looked forward to it very much, but the guy brought the things up and saw that it was a pot of beef with feet and a plate of braised pork.

Beef is the docker's name for the beef soup in the shed.

There are no seats in the shack, and the diners are not sophisticated. Spend a few pennies, take a bowl of beef offal and sit casually on the stone steps of the wharf, eat with your feet crossed, get down from the boat and look up, all of them are cocked hemp soles, which is simply called beef with crossed feet.

This matter is still regarded as an interesting thing to tell Su Youyan.

And the braised pork platter is another flavor of ingredients, pig water.

The head and hooves are bloody, the Song people don't eat much, and this thing is also something that no one wants, a big pot of lo-mei, and the main cost is the money for medicinal powder and the labor of washing the ingredients.

However, the lo-mei made is indeed commendable.

This thing Su You suggests Ba Niang, the price can be slightly higher, fifteen wen a dish, it is a thing for the poor to celebrate the festival.

Su You knocked on the basin with chopsticks: "Disciple, his heart should be punished!" I invented this thing, and you're using it to fool me now? Your table looks lively, that is, less than fifty cents. ”

Shi Tong said with a smile: "I was born in the Shi family, so I don't have so many taboos when it comes to eating, I won't let go of what is delicious, it seems that the master is also a member of my generation!" ”

Su You sandwiched a chopstick pig's head meat and put it in his mouth: "The brine is still too new, not soft enough, but overall it's not bad, come and talk while eating." ”

The two of them sat down, and the master was not like the master, and the apprentice was not like the apprentice.

After eating half full, the two began to slow down and talk.

Su You asked: "What is the general situation of the industry in Meishan City?" ”

Shi Tong said: "Su Cheng Shi Shi four families, in addition to the chewing grain of Zhuangzi in the countryside, mainly rely on merchants to set up a family business. ”

"Our Shi family was born in Jiangmen, so slaughtering, smelting and forging, gold and silver in and out, are mostly in our hands."

"The Shi family controls the ceramic industry, the Su family controls silk and cloth, and the Cheng family controls printing and crude medicine."

"These are the main business, as for the others, either they are the children of the family, or they are other surnames, but they are not the main business of Meishan City."

Su You asked, "What about transportation?" ”

Shi Tong said: "The transportation is mainly the Jiang Qing family in Jiazhou, where several major rivers converge and the shipbuilding industry is developed. ”

Su You then asked, "What about the land route?" ”

Shi Tong said: "The land route is troublesome, it is all coolies. He formed a caravan of horses and camels, crossed the mountains and mountains to Dali, Qiang Village, and the ghost party, and traded with the barbarians. It's all hard money. Our Jiang Qing family is a sitting tiger and does not participate. ”

Su You nodded, and had a rough understanding of the economic layout of Meishan City.

Shi Tong said: "If you talk about the strength of money, Meishan first pushed the Cheng family, printing books is really a million profits, but the labor is very expensive, you must be proficient in literature and science, and the engraving has to accumulate for several generations before it can be done. ”

Speaking of this, Su You also had to admire: "That is, the two Jinshi in Mrs. Cheng's family for three years are the embodiment of strength." ”

Shi Tong continued: "Since Taizu's cup of wine released the military power, my Shi family has learned to be obedient, this gold and iron benefit is actually no less than books, but the reputation is not as good as the scholarly family, and the work is also more difficult. ”

Su You stopped what he was doing and looked at Shi Daodao: "Shi Lao, and you, even the blacksmith work can be done by yourself, this is also a kind of tutor, not a child of anointing." ”

Shi Tong stretched out his slap forward: "Look at my calluses!" Not to mention anything else, it is my aunt and grandmother, who have to get up at five drums every day to practice guns and sticks. My Shi family, I can't do hard work, I rely on hard work. ”

Su You nodded and said, "Your aunt and grandmother are innocent and simple, I like it very much." ”

Shi Tong heard Su You say this, grinning with joy: "Really? It's a matter of telling the truth, Master! ”

Su You didn't take it to heart when he heard it: "I've always told the truth. By the way, the Shi family's tutor, that is, saving, the profit of porcelain is not as good as printing gold and iron, and the capital is very large, and the Shi family is taking the path of ants moving and accumulating a lot, right? ”

Shi Tong laughed: "Master's metaphor is too appropriate, this is really the way of porcelain rooster to prosper the family." ”

Su You shook his head and said, "It's not easy...... By the way, what's going on with my Su family? Speaking of the Jiang Qing family, why is the family business so weak? It's not on the same level as the other three at all. ”

Shi Tong waved his hands continuously: "No, no, no, if you want to talk about the Jiang Qing family, the Meishan people may not accept anything else, but the Longli Su family, that's all this!" ”

A thumbs up.
