Hao Qing's workshop is always stocked with various raw materials. Among them, soda ash and limestone are worthless things. Hao Qing happily brought them to Su Hao. But when taking the quartz stone, Hao Qing was obviously
He showed some distressed look, which made Su Hao very disdainful.
"Brother Hao, it's just a few rocks. Are you feeling so uncomfortable?" Su Hao asked.
Hao Qing said with a bitter face: "Master Su doesn't know. This kind of glazed stone is not produced locally. My father spent a lot of money to buy it from Nanjing. It is intended to be used when someone wants to refine glazed stone. Use it now.
I still have to find a way to make up for it."
Su Hao took the stones and looked around, but he didn't see any difference between them and ordinary quartz stones. He asked Hao Qing: "Who did you hear that we don't produce this kind of stone locally? This is the most common stone in the mountains.
If you want a stone, I can help you find it at any time."
"Is this true?" Hao Qing asked, staring at Su Hao.
"Don't tell me it's not true. Get me a carriage. Tomorrow I can take your third son to the mountains and pull a carriage for you." Su Hao said.
Quartz minerals are extremely common on the surface of the earth. A total of 10 types have been discovered so far, including low-temperature quartz, high-temperature quartz, tridymite, cristobalite, coesite, Strychite quartz, etc. The appearance is different, but the main components are
The same thing is that they are all silica. Su Hao once inspected the mountainous area in the south of Fengcheng and conducted a rough study on the mineralization conditions in that area. He believed that with a little running around, he would be able to find one or two
The reserves of quartz mines in good locations may not be enough for later industrial production, but they are more than enough to meet the needs of Hao Qing's handicraft workshop.
"I don't need a car. If you can find me 100, or 500 kilograms, then I will give you these glass pieces you want for free," Hao Qing said.
Su Hao said: "It's a deal, but you're really worried. Let's make a note soon. I'll give you 1,000 kilograms of glazed stones. If you can't do it, I'll pay you 100 taels of silver."
Hearing that Su Hao was so sure, Hao Qing also believed it, so he smashed the precious glazed stones into small particles and put them into the crucible. The feldspar needed in the formula Su Hao said
, Hao Qing didn’t know what it was, but by coincidence, Su Hao turned around by chance and found a stone for stepping in the corner of the yard. It turned out to be the feldspar he was looking for, so he called Hao Tong and asked him to get it.
The hammer broke off a piece, which was also crushed and thrown into the crucible.
After the raw materials were prepared, Hao Qing put the crucible on the stove and started to ignite the smelting. As expected of a craftsman's house, he usually prepared good coke. The simple-minded little Wuzi with well-developed limbs pulled the bellows hard, and the flames
Bear, everyone gathered around the stove immediately felt the heat wave coming towards their faces.
"Master Su, you said you can't find good coke in Fengcheng County, how come my brother can't find it here?" Hao Tong still remembered what Su Hao said to him the first time.
Su Hao also knew that he was deceiving before, but now, he still had to continue to be tough. He said: "Your eldest brother is a craftsman. Of course he always prepares some coke. Who knows where he got it from."
"Can we borrow his coke to make that good pig iron you mentioned?" Hao Tong suggested in a low voice.
Su Hao looked at Hao Qing, who was handling the crucible, and really made some plans in his mind. To make glass, quartz sand and other raw materials need to be heated to about 1600 degrees Celsius. If this temperature is slightly raised, it can be used for refining.
Steel. It seems that the craftsmen of the Ming Dynasty have mastered the technology of making high-temperature crucibles with refractory materials. If they give some guidance, they may be able to refine some alloy steels of later generations.
Thinking of this, Su Hao stepped forward and asked Hao Qing: "Brother Hao, do you have a bigger crucible than this? If I want to use a crucible to make steel, can you do it?"
Hao Qing said: "I have heard my father talk about the method of making steel in a crucible. However, the steel made in this crucible is no different from that of fried steel, but it costs more, so now Wuru has adopted this method to make steel.
Steel."
Su Hao said: "The key to crucible steel-making lies in the formula. If the formula is correct, what we usually call hundreds of steel-making will mean nothing in front of crucible steel."
Hao Qing asked: "Does Master know this formula?"
Su Hao smiled and said: "There are more than a hundred recipes for making steel in the crucible, and my knowledge is limited. If we have the chance, we can slowly test it and we can always find the best recipe."
"Master, would you like to grant Xiao Ru the recipe for making steel?" Hao Qing asked.
Su Hao said: "This formula is not worth anything. The difficulty is that I can't get the ingredients in the formula together at the moment. If you are willing to cooperate with me, after I find the materials, let's test it together."
"Xiao Ru is willing to serve Master." Hao Qing replied.
In fact, Su Hao didn't know the formula for making steel. What he did know was that there were various alloy steels in later generations, which were made by adding various elements to the steel. He was the person in charge of prospecting, and what kind of alloy steels were there?
He was very familiar with the elements that could be used to smelt alloy steel, but he didn't know exactly which elements to add in how much. Gu Jin also knew some methods of smelting alloy steel, but after all, he didn't have as much theoretical basis as Su Hao. In addition,
, the minerals needed to smelt alloy steel can only be recognized by Su Hao.
As he spoke, the raw materials in the crucible had begun to melt. Hao Qing carefully observed the state of the glass liquid. When he felt that the various ingredients in the liquid had been completely mixed and there were no bubbles in the liquid, he used pliers to clamp it.
Hold the crucible, pour the glass liquid into the prepared mold, and then wait for the glass liquid to condense.
"Is this a success?" Looking at pieces of transparent glass being poured out of the mold, Hao Qing couldn't believe it was true. He tried to pick up a piece of glass, knocked it, and then broke it with his hands.
After breaking it, he couldn't help but exultantly said: "It's done, Master, this colored glaze is really done!"
After saying this, without waiting for Su Hao to answer anything, Hao Qing took the glass in his hand and ran to the side room. After a while, an old man with gray hair and a slender figure held the piece of glass in his hand.
Glass, accompanied by Hao Qing, walked out of the wing and walked slowly to Su Hao and others.
"This is my uncle, whose name is unknown to him because of his family name." Hao Tong introduced to Su Hao in a low voice from the side.
It turned out that the old man named Hao Yizong had been hiding in the wing and observing what was going on outside. When Su Hao proposed to burn the glass, he did not come forward, but just let his son Hao Qing deal with Su Hao. Now according to the rules
Su Hao's formula really produced glass. Seeing the glass sample sent by Hao Qing, Hao Yizong finally couldn't sit still.
"Hello, Uncle Hao. This junior Su Hao is polite here." Su Hao took a step forward and saluted Hao Yizong.
Hao Yizong hurriedly returned the greeting and said, "How dare you? Master Su is here. I didn't come far to greet you. Please forgive me for my sins."
Hao Qing also hurriedly tried to smooth things over and said, "My father has some inconvenience, so I couldn't come out to greet Master Su just now. Please forgive me."
"What the hell, this junior didn't know that my uncle was at home, otherwise I would have gone to say hello first and ask my uncle to forgive me for my ignorance." Su Hao also laughed, since polite words are not worth much anyway.
Su Hao knew in his heart that Mr. Hao had been hiding in the side room before, obviously because he didn't want to deal with him. The so-called inconvenience in his legs and feet was just an excuse. Now he saw that he actually knew the formula of glass, and it was obvious that this formula was better than the old man's formula.
Even more clever, the old man showed up now. Speaking of which, it is not because of his reputation as a master of the workshop, but because of the power of knowledge.
"Master Su, I just heard Quan Zi say that Master made colored glaze without using saltpeter or sheep's horn as a guide. Can you explain to me the reason?" Hao Yizong asked Su Hao.
"What are ram's horns?" Su Hao asked. Previously, Hao Qing only admitted that saltpeter was used when burning glass, but did not mention what kind of ram's horn it was. Now Mr. Hao opened his mouth and let it out, obviously thinking that they
The formula I kept secret was no longer valuable, so there was no point in letting Su Hao know it. But, what does this horn refer to? Is it the common name of some mineral?
"Sheep's horns...are the horns of a sheep." Hao Qing explained calmly. He couldn't understand why there are still people in this world who don't know what a sheep's horn is. Has this scholar never seen a sheep?
"You mean, that kind of living sheep...with horns on its head?" Su Hao asked in surprise, while making gestures on his head with his hand, imitating the appearance of a Pleasant Goat.
"Of course." Hao Qing said a sentence.
"I sell cakes..." Su Hao sighed. It turned out that goat horns were really used as raw materials for making glass. Who invented this recipe! The main component of goat horns is calcium oxide. Apparently, goat horns were used as raw materials for making glass.
As the source of calcium in glass. To infiltrate calcium into glass, just throwing two pieces of limestone is enough. Why use such a weird material? To burn a piece of glass, you need to use several pairs of horns. No wonder the output of this glass
Can't come up.
"Uncle Hao, this ram's horn... is really useless. The purpose of the ram's horn is the same as the limestone my nephew uses. As for saltpeter, its purpose is the same as alkaline earth, and alkaline earth is much cheaper than saltpeter.
And it's easier to find." Su Hao explained simply.
"That's it, that's it..." Hao Yizong murmured to himself. He looked at the piece of glass in his hand repeatedly. After a long while, he hesitated and asked: "Master Su, are you willing to pass on the formula for making colored glaze to me?"
Are you old and decrepit?"
"Uncle, didn't Master Su tell you all the recipes just now? And the eldest brother has also made it himself, what else do you want him to pass on?" Hao Tong said carelessly from the side.
"Tong'er, I'd like to speak!" Hao Yizong shouted, "Master Su's formula is priceless. Master Su just trusted us and didn't hide it from us. It's rare for us to see the magic of this formula. How can we not do it without it?"
Master Su allowed me to take this recipe as my own? As craftsmen, we will be punished if we do this."
