Zhao Hao hurriedly gave the humanoid material analyzer, oh no, Pan Zhongcheng applauded.
Yes, this cement is added with a certain proportion of pyrite slag, which greatly improves its strength!
After three months of unremitting efforts by the exploration team, they finally found the location of the pyrite on Xishan Island.
But this is only the purpose of pyrite slag. Zhao Hao is not looking for pyrite to make cement, or even to make iron.
Because the iron content of this product is less than half, with the current smelting level, it is impossible to get pig iron of good quality even to death.
But its sulfur content is more than half, and sulfur and sulfuric acid can be easily produced.
In fact, no decent natural sulfur mine was discovered in our country until four hundred years later. Sulfur and sulfuric acid required in industrial production have long been extracted from pyrite.
Pan Jixun picked up a square piece of golden pyrite and couldn't help but praise it: "Beautiful, so beautiful, I can't bear to eat just looking at it."
"No wonder scammers used it to pass it off as gold, it looks so similar." Zhao Hao nodded in agreement. In the West, pyrite has long been regarded as a cheap ancient gemstone.
"That's because they are too stupid, won't you know if you try it?" Pan Zhongcheng took a bite, and with a click, he bit off a corner of the ore. "Bang crisp is completely different from gold."'
"Hi" Zhao Hao didn't know whether to laugh or cry. "Who has teeth like yours?"
"It's crispy, just like eating a popsicle. If you don't believe me, try it." Pan Zhongcheng handed Mr. Zhao a piece.
Zhao Hao is naturally grateful but not sensitive. He quickly pointed to the third ingredient and said:
"You can eat more of this, and it can also cure your bloating."
"Huh?" Pan Zhongcheng looked at the small compartment and found a few crystal-clear rock candy-like things.
Pan Zhongcheng twisted a piece, stuck out his tongue, licked it, smacked his lips and said: "It's salty and bitter, this is saltpetre"
As he was talking, he seemed to think of something, and suddenly changed his face and said angrily: "Good boy, how dare you cheat on me!"
"Zhongcheng, don't get me wrong, this is not made from urine, but natural Glauber's salt." Zhao Haoxin said that he is quite picky about food. He hurriedly explained, and then he calmed down the old man who wanted to eat people.
"Oh?" Pan Jixun couldn't help but said in surprise: "Is there still Glauber's salt on Xishan Island?"
"This is not from Xishan Island, it was obtained from Fengyang Mansion." Zhao Hao replied with a smile:
"It's a coincidence. Last month, Wu Ji discovered that someone was selling fake white sugar and rock sugar. After some investigation, it turned out that they were using Glauber's salt instead."
"I arrested the people and brought them to the county for interrogation. I found out that they came from Fengyang Mansion, where there is a large amount of natural Glauber's salt. I asked Uncle Mi to investigate and brought these back and asked Zhongcheng to give them to me. Let¡¯s see, is it necessary to take action?¡±
"It's necessary, the bitterness is pure and the saltiness is so refreshing." Pan Jixun nodded without hesitation: "It's much purer than the one made from urine Ahem, I'm just guessing, I've never tasted that kind. Woolen cloth."
"Oh." Zhao Hao nodded happily. There are too many impurities in the soil salt produced by the pile salt method. With high-purity Glauber's salt, the power of gunpowder can definitely be greatly improved.
He also said sincerely: "The ice made in this way finally loses the smell."
"Elaborate!" Pan Jixun couldn't help but praise. He will also travel five to six hundred miles to find better ingredients for purer delicious food.
This is the attitude that a young man from an aristocratic family should have.
"This is the quartz sand brought back from Fengyang by the way. Zhongcheng probably can't chew it, so Pinpin will spit it out." Zhao Hao pointed to the last one.
Fengyang is a good place. Not only is there the only high-grade thenardite mine in South Zhili, but also the only high-grade thenardite mine in the entire south, and the only quartz sand mine in South Zhili.
The reason why Liulichang in Beijing cannot produce glass is because there is no high-quality quartz sand.
Pan Zhongcheng chewed it for a long time in disbelief, then spit out the quartz sand in his mouth helplessly, took the cup and rinsed his mouth and said: "Weak ribs."
Having said that, he was still very satisfied with the first three meals, and he actually seemed to have regained his strength.
The two were discussing the difference in taste between quartz sand and ordinary river sand when Gao Wu knocked on the door.
After a long silence, Brother Gao reported: "Zhongcheng's family is here."
"Oh, please come in quickly." Zhao Hao stood up.
¡°Put these away first, let them see them and talk about me again.¡± Pan Jixun stuffed a piece of Glauber¡¯s salt into his mouth and hurriedly closed the lid of the box.
Zhao Hao quickly stuffed the wooden box into the bedside table.
At this time Gao Wu also opened the door, and an old man who looked to be about the same age as Pan Jixun came with two??The young people came in quickly.
"Father!" The two young men lay on Lao Pan's bedside and burst into tears.
The old man also stumbled forward, held Pan Jixun's hand and wiped his tears.
"Brother, why are you crying? Am I not okay?" Pan Jixun comforted the old man, then glared at the two young men and said, "Why are you two mourning? I'm not dead yet, stand up."
The two young men were really obedient. They stood up obediently and sobbed without daring to cry.
Pan Jixun then introduced three people to Zhao Hao. The old man was his second brother, Pan Zhongzhi, who was a Jinshi in Jiajing for 20 years, and the two young men were his eldest son Pan Dafu and second son Pan Longhan.
After the two parties met, Zhao Hao apologized to the three people again, saying that he failed to take good care of Pan Zhongcheng and made Zhongcheng suffer. He also sincerely invited the three of them to stay in Kunshan for a longer period of time and let them fulfill their friendship as landlords.
"Don't be polite. They all know that this is an old problem." Pan Jixun waved his hand so that Zhao Hao didn't have to blame himself.
"Yes, Mr. Zhao. My fourth brother's temper is unbearable for ordinary people. We are so grateful that you can tolerate him for so long." Pan Zhongzhen also comforted Zhao Hao and said: "It happens that the two miracle doctors are here, and they will definitely be able to treat him." The disease is cured.¡±
Zhao Hao greeted them for a few more words, then wisely stood up and left, letting the whole family talk.
But Pan Jixun stopped him and said, "Do you think my two sons are still capable?"
"Haha" Zhao Haoxin said, this is my first time meeting you, who should I ask?
But there was no room for praise in his mouth: "Zhongcheng has a well-educated family and a rigorous family management. At first glance, the two young masters are both good and bad, and they will probably achieve great things in the future."
"Since you are so optimistic about them, let them stay in Kunshan." Pan Jixun climbed up the pole and said: "Isn't your Yufeng Academy about to start school? Anyway, two more are not much, so just take them in These are the two students."
"Uh" Pan Zhongzhen opened his mouth when he heard this, but stopped talking. He was born as a Shuji scholar, but he had violated the strict party and had to resign early and return to his hometown, where he devoted all his efforts to teaching his nephews.
The Pan family was able to have children, and the four brothers gave birth to nineteen sons, among whom Pan Jixun was the most successful.
Now, when he sees his fourth brother, he doesn¡¯t even consult with him, but immediately pinches his head. Naturally, Pan Zhongzhen finds it hard to accept this.
But since his son belongs to someone else, he could only watch Pan Dafu and Pan Longhan kowtow to Zhao Hao and feel his heart was broken.
Pan Jixun saw his second brother¡¯s disappointment, and while his two sons were sending Zhao Hao out, he whispered to Pan Zhongxun:
"Second brother, the boy named Zhao is a god. Children can learn much more by following him than by following us."
"Oh, really?" Pan Zhongzhen looked at his younger brother who always had higher eyesight in surprise. I don¡¯t know how that young man with no hair at all conquered him.
"It's true. Not only these two children, but also the next generation of my Pan family will go to Yufeng Academy to further their studies. I'm going to work for him in Kunshan, so I can't deny this convenience, right?"
Pan Jixun puffed his beard and stared, and then said a little embarrassedly: "Although we do have a lot of people in our family"
