After a hurried dinner and thanking Master Miles for his generosity, Todd took a few pieces of white paper from the classroom, a set of rulers, a few charcoal pencils and half a candle, and buried himself in his
room, and started doing what he was best at in his previous life.
Design of chemical experiments and practical industrial applications.
In the afternoon, by observing the waste residue extracted from the silver mine and asking the craftsman Aiden for confirmation, Todd already had some clues about the next work.
The "North Stone Mine" mines and smelts silver ore. Although the "ash blowing silver smelting method" is used, because the royal craftsmen's understanding of mineral elements and chemical reactions is still at the primary stage, only about 60% of the silver in the ore is extracted.
% to 70%, but about 30% of the silver was still lost in the waste and was given to the Monastery of San Sidro as garbage.
Why does such loss occur?
Mainly because there are some impurities in silver ore, such as bismuth, tellurium and lead oxide.
Because these impurities have a high affinity with gold and silver and are not easily oxidized, precipitated, attached and recovered, they can always copolymerize with silver in the lead liquid during the soot blowing process, thus reducing the recovery rate of silver.
Due to the lack of understanding of metal refining, smelting in the Middle World often stopped operations after the first stage of ash blowing. What Todd has to do is to carry out extended operations in the second and third stages to further extract silver.
Reduce losses caused by impurities.
The principle is roughly like this. The key is how to rely on the existing equipment and materials on hand to carry out the secondary and tertiary refining of silver mine waste residue.
Forget about the early 19th century electric furnace ashes blowing method.
The roulette-type ash blowing method of the late 17th and early 18th centuries was simply not possible.
Even the high-tube soot-blowing furnace of the mid-16th century is difficult to implement under today's conditions.
By comparison, only the early cladded ash-blown furnaces from the late 13th and early 14th centuries can barely be reproduced.
While recalling the shape of the furnace in my mind, I used charcoal pencil and a ruler to describe the refining steps and improvements to the equipment on the white paper.
Todd, who was obsessed with scientific research, quickly forgot the passage of time.
Finally, the candle burned to the end, reminding him of the time to work and rest.
Looking at the half-finished drawings in the dark, Todd held his forehead in depression. This feeling of being forced to stop halfway through the work was the most intolerable to him.
Through the bricks above his head, he looked at the bright moon hanging high in the sky, sighed, and had no choice but to climb into bed and choose to sleep.
Early the next morning.
The watchman's waist clock became the sound he least wanted to hear.
But he also knew clearly that if he delayed his morning class, it would not only arouse unnecessary suspicion from others, but would even make it impossible for him to stay here any longer.
Bracing himself up, putting on monk clothes, rubbing his sore eyes, Todd carefully folded the drawings on the table and placed them under the bed board. Although the labels on the drawings were in Chinese, the chemical elements and equations were not.
People have seen it, but it’s better to be cautious about this kind of thing.
Hiding in the corner, yawning, and after everyone finished reading the morning lessons, Todd had to rush to Master Miles to learn new lessons.
Grammar, rhetoric, logic, arithmetic, and geometry were acceptable to him, but music and astronomy were what really killed him.
Music is relatively good, but firstly he doesn't know it, and secondly he's not interested in it, so he just muddles along in class.
Astronomy is the biggest problem.
Let a soul that has been baptized by modern civilization accept the education of church astronomy, let alone a teacher with a background in scientific research.
My mind is clearly shouting nonsense and nonsense, but my mouth is shouting that it is like this, I need to be taught and taught.
During the lesson, perhaps because he noticed that Todd was not in high spirits and was not in good spirits, Master Miles took the rare opportunity to interrupt the class and start a conversation with the apprentice opposite.
"You are the most talented student I have ever seen."
Hearing the old man sitting across from him put on a "high hat" for himself when he came up, Todd thought something bad in his heart and pretended to be listening attentively.
"Heavenly Father has given you protection and blessing. There is no doubt about it. If you calm down and practice with concentration, you may become the first among us to be close to a sage."
Todd still lowered his head, vaguely feeling that the hat on his head would soon break through the roof and point to the sky.
"but……"
Pouting his lips, Todd touched the bridge of his nose with his fingers and thought to himself, there is indeed a but.
"Don't waste your time and energy on those trails."
Edgar, you have a big mouth!
Todd thought to himself: I just guessed that when we talked about these nonsense topics today, it must be Edgar, the bastard, who reported yesterday's events to Master Miles.
Todd, who was still unwilling to give up, raised his head and tried to persuade the old man: "Master, if I have a way to slightly improve everyone's life, wouldn't it be able to help everyone better understand the true meaning of the Holy Way?"
"No! My child, this idea is not correct!"
In Todd's impression, this was the first time that Master Miles had such a serious look on his face. He only heard him say: "Wanting to improve life is just an excuse for laziness and decadence. A comfortable life will
It wears down our will, dulls our thinking, and empties our body. Monks who are truly devoted to the holy way should abandon all distracting thoughts and all worldly things, and dedicate their whole life spirit and life to the Father!"
The corners of his eyes twitched. Todd wanted to argue again, but after thinking about it carefully, he realized that this was definitely not a good idea. He quickly buried his head and closed his eyes to prevent the old man from seeing his questioning and dissatisfied expression.
After a long time, Todd choked out a sentence from his throat.
"I will obey my master's instructions."
————————————————————
After finishing his morning studies, Todd walked out of the classroom feeling that the world was dark.
Obviously there is a way to eat exquisite food, wear brand-new clothes, and do not have to work and run around late every day. You can focus more energy and time on research and academics.
Why should we refuse such a life?
He couldn't understand.
Out of the corner of his eye, he caught a glimpse of a figure appearing in the corner.
Seeing clearly who the person was, Todd immediately became furious. He took off his shoes and ran away with them in his hands, while cursing in his mouth: "Edgar, you little bastard! I asked you to tell the truth about this big thing about me!"
Following the escaping figure in front of him, passing through several corridors and passing through several corners, Todd bumped into the arms of a person.
Huggins, who had been waiting for a long time, dragged the grimacing Edgar behind him and said to Todd: "I heard that you have a way to make us eat meat every day?"
