Chapter 69 "The Book of Commandments"
In the study room, Fang Jun drove everyone away, holding his pen in the air with a tangled face.
It is said that soap is much easier to make than glass, but how is the most critical caustic soda made?
Caustic soda can be made with soda ash. Soda ash is easy to obtain, but what does it react with to get caustic soda?
No matter what, first write down everything you remember and know, and study it slowly.
First I wrote a rough recipe for soap, recording all my doubts and difficulties, and then I wrote a recipe for glass. Of course, the so-called formula is just a few raw materials. As for the detailed proportions of ingredients, ahem, who in the age without Du Niang can know...
After thinking about it, he locked the soap formula in the cabinet. He still had to think carefully about the caustic soda and supervised the production himself. However, he remembered that making soap would have a by-product - glycerin. That thing would react with some strong oxidants. Explosion, it's better to be careful and don't cause a big incident.
He is considered a half-baked science student. He has forgotten all the chemistry knowledge he learned back then. He can't remember the equations at all, but it doesn't matter. He knows that glass is made from quartz, soda ash and limestone, and soap is made from caustic soda and lard. The gunpowder that came out was even made from sulfur, saltpeter, charcoal, and that was enough.
There is soda ash in the natural salt lake. He has heard the saying "salt in the summer, and soda in the winter." There is limestone in the mountains, and quartz is plentiful in Shaanxi. As for the formula ratio of various raw materials, the exchange Just let the servants experiment. Anyway, as long as the glass is burned, the quality doesn't matter.
Many great inventions in human history began with a sudden inspiration and were born after tens of millions of failures in the laboratory.
Now that Fang Jun knows the right direction, it is enough to at least ensure that this road can definitely reach the end, and has greatly shortened the distance to success.
When he called Lu Cheng into the study and handed him the raw material formula for glass and some precautions, he clearly heard the guy sigh quietly. He probably still thought Erlang was fooling around and didn't listen to Fang Quan's advice at all. .
It’s no wonder he thinks so. If you get a bunch of rocks and put them together and burn them, you can make an egg...
Fang Jun was so depressed that he simply ignored him and had no time to pay attention to him.
Because King Wu Li Ke came again.
Fang Jun's strategy of "breaking stones to record merit" made His Highness the King of Wu turn around in a sluggish situation. It was a stroke of genius.
This fair and just conspiracy not only amazed all those who knew about it, but also completely conquered the rich and handsome His Highness King Wu.
Still graceful and free, still tall and tall, still so handsome...
Fang Jun's eyes twitched, a little jealous, how could a man look so handsome? However, there is no trace of femininity, and the whole person is sunny and healthy. This is too damaging to other people's self-confidence...
Li Ke didn't notice Fang Jun's strange look, so he grabbed Fang Jun's hand and said happily, "Thanks to Erlang this time, brother Yu will always remember his kindness."
He is a strong person. It's not that he can't accept failure, but he is not convinced when he loses to his opponent's conspiracy.
Now that I have made a strong comeback, I am naturally in a better mood and my demeanor and behavior are more friendly.
But Fang Jun can’t stand it...
You say the ancients were hypocritical. No matter how good their relationship is between two grown men, do they have to hold hands to express it?
So disgusting...
Shaking off Li Ke's hand without leaving a trace, Fang Junqiang smiled and said: "Your Highness has given you too much praise. I dare not take credit, but I am just a rude person..."
"Alas!"
Li Ke pretended to be displeased: "My dear brother, don't be humble, let alone belittle yourself. If anyone dares to say that my dear brother is a rough man, then everyone in the world will be rough..."
Fang Jun's mouth twitched. According to what you mean, I am the slimmest man in the world...
Li Ke was very happy. He walked into the main hall without seeing anyone else and said: "There is also the hot pot you sent. I ordered someone to send it to the palace. I asked your craftsmen to make another one for me. I will bring it. ”
"That's no problem. It will be delivered to His Highness's house in two or three days at the latest. Your Highness, please have a seat."
Hearing that there was money to be made, Fang Jun felt better and became more polite.
But it is sad to think about it. I used to be a county-level cadre, and now I am the most prominent second-generation official in the Tang Dynasty. How can I worry about money...
A few copper hot pots have been sold one after another, but this thing has no technical content, and it is said that some people in the world have begun to imitate it. And for Fang Jun, who has inherited our party's fine tradition of "doing things quickly", this thing is too slow to make money...
But no matter how lean a grasshopper is, it is still meat, and selling it for a few more bucks can ease the cost of purchasing glass raw materials. Ever since he knew that his family's financial situation was not good, he never asked his family for money again. In any case, being a rice insect is not a glorious thing.
"My father has already made a decision to appoint me as the governor of Anzhou once again."
Li Ke sat relaxedly on the couch, with a happy face, and his handsome face seemed to be shining. As he spoke, he took out a letter and handed it to Fang Jun.
Fang Jun sat across from him and randomly signed a new sign. He took a look and was shocked.
There is no letterhead or signature on the new signature, the font is calm and natural, the writing style is euphemistic and implicit, the whole text is beautiful and strong, and has the charm of Wang Xizhi. It is actually a letter written by His Majesty Li Er to Li Ke's family.
"I use the king's presence to herald the common people to show that I am righteous to all nations. You live in a prosperous land with close relatives. You are surrounded by the screen. I encourage you to think about the way of bridges and catwalks. You are good at the virtue of peace among people. You control things with righteousness and control your mind with etiquette. You are free from the three winds and ten mistakes. , don’t be careless. In this way, you will be able to consolidate the rock and protect it forever. Weicheng. On the outside, there is the loyalty of the monarch and his ministers, but on the inside there is the filial piety of father and son. It is advisable to encourage yourself and make new progress with each passing day. You are kneeling down, why are you so sad? I want to leave you treasures, but I may be arrogant and extravagant. Therefore, I warn you. Court training.”
What does it mean?
Roughly speaking, His Majesty Li Er hopes that Li Ke should be upright and courteous in his dealings with others, be self-motivated and self-motivated as a minister and son, and not be arrogant and extravagant just because he is the emperor's son.
The handwriting is very good, and the wording is also very particular. At a glance, it is just a letter from home.
But the key is in the last sentence.
This is clearly a letter from the father to educate his son, and it should never be said in his capacity as the emperor. This shows that His Majesty Li Er values and favors Li Ke.
But Fang Jun became more and more confused. Since His Majesty Li Er loves Li Ke so much, why does he never put Li Ke among his goals?
After reading the letter, Fang Jun respectfully handed it back to Li Ke with both hands.
This is not because he is holding His Majesty the Emperor's calligraphy treasure, but because of Li Ke's trust.
Being able to show Fang Jun the family letter written by the emperor to him shows that Li Ke already regards Fang Jun as a close friend and is unsuspecting.
For Li Ke, who was born in the royal family and was deeply involved in the dispute over the heirloom, it was extremely rare.
Fang Jun values love.
Even though he knew that the handsome and suave Prince Wu in front of him was a short-lived ghost and was definitely not a giant tree that he could rely on, nor would it bring him any substantial benefits, he still happily accepted this friendship.
You treat me as a national scholar, and I should repay you as a national scholar!
You treat me like a stranger, and I will treat you like a stranger!
If you treat me with contempt, I will repay you with hatred!
This is Fang Jun's life creed, the life creed of a "half-baked official" who is not fully profit-oriented. (End of chapter)
