Gao Qiu finally returned home after getting off duty, only to see his son who was busy all day long in his yard.
She was chatting happily with her mother, Mrs. Huang, which made Mrs. Huang smile happily. She hugged her biological son and smiled very happily.
Seeing this scene of a loving mother and a filial son, Gao Qiu couldn't help but feel happy. After striding into the house, he smiled at Gao Zhang.
"Zhang'er, looking at you today, it seems like something good has happened to you."
"Yes, Dad, thanks to you, the child never thought that the worries in the child's heart could be solved in one fell swoop."
Huang smiled and nodded and agreed.
"Yes, Zhang'er told me just now that my husband has really helped our Zhang'er a huge favor in military affairs."
"???" Gao Qiu glanced at his wife, Huang, with a confused look on his face, and then at his son Gao Zhang, feeling a little confused.
Why don't I, an old father, know that I have done my own son a favor again?
Seeing his father's expression, Gao Zhang explained.
"Dad must not know that the craftsman, Master Xue, not only knows how to make glass, but more importantly, he knows how to make coke."
"Coking?" Gao Qiu's face was filled with confusion.
"Yes, it's coking, because there are many impurities in coal.
When used to smelt iron, it is easy to cause excessive impurities in the steel, resulting in poor quality.
This is also an important reason why daddy said before that the quality of our Song Dynasty imperial armor was not up to par. "
I saw my son Gao Zhang with a proud face stating the reasons why the quality of steel in the Song Dynasty was poor despite its large quantity.
Seeing Gao Zhang's confident and calm expression, his wife Huang's face was still filled with a loving smile and her heart was full of joy.
Gao Qiu's original impulse to express his opinion was suppressed.
Although Zhang'er is indeed smart, talented and knowledgeable, the problem is that smelting steel is something that only professional craftsmen can do.
Gao Zhang was entrusted by the officials to spend some time in the iron shops and smelting workshops these days.
But he has already made himself look like an experienced driver who knows everything.
However, I saw the loving expression on my wife Huang's face and the cute and adorable look on my son's face.
Forget it, it's just a small matter, let Zhang'er figure it out on his own.
For a person with such high emotional intelligence as Gao Zhang, he immediately reacted when he saw his biological father, Gao Qiu, looking a little perfunctory.
"Daddy, do you think the child is acting up?"
"That's not true. Dad is just thinking that my son is smart. Since he thinks it is useful, there must be something wrong with it."
"It's just that we must not let this news leak out before we get good quality steel."
"That will have an impact on my son's reputation, which is not good."
Upon hearing that it would affect her son's reputation, Huang immediately became wary and nodded repeatedly.
"Yes, yes, Zhang'er, your father is more thoughtful."
"Well, father and mother, don't worry. If your children know it, they will definitely do things in a low-key manner first."
"When I can use coke to make fine steel, I will ask my father to take care of it for me."
"Of course there is no problem. As a father, I trust you Zhang'er."
Gao Qiu looked at the Gao Jiawen opera star who was neither anxious nor bored after hearing his reminder, and couldn't help but feel relieved. What more could a father ask for if he has such a son?
#####
With Gao Zhang, the son of the Song Dynasty's number one scholar and Taiwei, as his backstage, Xue Da felt that he had never felt so comfortable doing anything.
Outside the city, I saw an open space near the water, which was very suitable as a place for coking.
It just looks a little small. Both sides of this open space are woodland near water, and they are all owned lands.
Fukang, the high-ranking housekeeper appointed by Xiao Gao to coordinate the work, only asked him clearly about his requirements and plans.
He didn't say anything on the spot, he just said he would come back tomorrow.
The next day, when Xue Da led his two sons over again, they found that there were no trees in the forest on both sides of the open space.
The area of the open space is almost ten times larger. Don't ask, just ask about the ability of the Taiwei Mansion.
As for Xue Da's desire to pick bituminous coal, there were people from all over the world in one afternoon.
More than ten kinds of bituminous coal sold in Bianliang, Tokyo were placed under Xue Da's nose.
As for the kiln for firing glass and the kiln for coking that he planned, as long as he can figure it out.
You will see these things appear in the open space in the shortest possible time.
It feels like a top chef trying to make a stir-fry.
Someone will get him the freshest kidneys, shave off the inner membrane, clean them, set up a chopping board, and prepare ginger, garlic and other spices.
There was also a raging fire in the stove, and an iron pot was placed, with oil, salt, sauce and vinegar all available.
All he needs to do is show off his excellent knife skills, cut off the kidneys, and stir-fry them.
It is precisely because of this kind of preparation that he does not need to do any work at all, and everything will be solved and completed as quickly as possible.
Especially after coming to Tokyo, I heard a lot about Xiao Gao's reputation as a benevolent and righteous man who loved the people and acted chivalrously.
This made the Xue family, who had been uneasy all the way and fearful after arriving, finally feel a lot more at ease.
However, Xue Da also has a sense of urgency. Xiao Gao Zhuangyuan uses people and efforts just to produce glass. How could I not do my best?
After the kiln entrance was completed, Xue Da immediately devoted himself to the work of making coke, and the three of them, father and son, went into battle together.
After the hard work of Xue and his son, the first furnace of coke was finally produced.
After the coke was released, Gao Zhang, who received the news, put aside what he was doing and rushed outside the city as soon as possible.
Looking at the coke that had been placed outside the kiln, Gao Zhang frowned tightly.
Picking up a piece of coke that was still warm, it was about the size of Gao Zhang's fist.
This is quite different from the size of coke in Gao Zhang's impression. You must know that in later generations, the blocks of coke were not large, that is, blocks of two or three centimeters.
It is said that because of the large pieces of coke, it not only wastes fuel, but also takes a very long time, and it is easy to be difficult to coke in the center.
Gao Zhang slapped the fist-sized piece of coke on the ground. After smashing it into pieces, he saw that the center of the piece of coke looked like more coal than char.
Seeing Gao Zhang's frown, Xue Da explained in a low voice.
The main reason why coking is time-consuming is that the coking coal needs to be broken into similar sizes. Small ones are unusable, and large ones are prone to failure to produce good coke.
"Well, that makes sense, but Xue Da, have you noticed that the center of the coal has not yet become charred?
Why don't you give it a try and select coal blocks about one inch in size to make it and see if it saves more time and effort. "
