Chapter 106: Doctor of Hardware

Su You didn't understand. He did a lot of things, including artificial incubation, punching, forging hammers, carburizing, test paper... "Uh, uncle-in-law, can you give your nephew a heads up? What are you talking about?"

"

Cheng Wenying was not polite and pointed at a porcelain vase and a porcelain box on the bookshelf: "Those two piles!"

Su You breathed a sigh of relief when he saw it: "Oh, those are borneol and borneol oil. They were also made yesterday. I promised to get fragrance for the bookstore and I was about to tell my uncle-in-law."

After speaking, he said with a smile: "Originally my nephew just wanted to make camphor, but he didn't expect that what he got was borneol."

Su Shi laughed: "Mingrun didn't know this thing before? How did he make it?"

Su You said: "Is it very complicated? I found that things with aromatic smells are generally easy to disperse in the air. I called this characteristic volatility."

"And among the many volatile substances such as various flowers, mint, etc., the one I am most familiar with must be"

"Fine wine!" Almost everyone said in unison.

Su You smiled and said: "Yes, since they are of the same nature, they should be available with the same preparation method. Therefore, the aromatic substances in the leaves can also be extracted using the process of refining fine wine."

Su Shi then nodded: "My mother thought it was unbelievable before she didn't understand it. Once Mingrun explains it, it will become natural. It's just that others wouldn't think of it. It's true."

Cheng Wenying said: "Come on, if it was really so easy, it wouldn't be at this price now. Zizhan, you have read a lot of books. I heard that this thing comes from overseas, right?"

Su Shi said: "This Dipterocarps has been recorded in "Historical Records of Huo Zhi Biography". It is recorded in the books of the Southern Dynasty that it was born in the Lu Kingdom of Xihai. It is the resin in the Lu tree, which is like white gelatin." Youyang Za in the late Tang Dynasty

Volume 18 of "Zu" mentioned that dipterocarp is also known as 'Gubu Bolu'. Its trees are either fertile or barren. The barren ones produce dipterocarp incense, and the fat ones produce Polu ointment. The fragrance is in the heart of the wood. The Persians cut it off.

Cut the tree, and the paste will flow out from the end of the tree. Cut the tree to make a ridge to support it. There are different ways to use it medicinally. "Tianbao powder, Jiaozhi Gongborneol, shaped like a cicada and silkworm. Persian: Old borneol tree

When there is a festival, it is called Rui Long Nao in the ban.'"

At this point, Su You understood that the word "Rui Nao" that often appeared in Li Qingzhao's poems turned out to be this thing...

Su Shi continued: "According to the grade, Ruilongnao is divided into cooked brain, plum blossom brain, rice brain, white cantaloupe brain, oil brain, red cantaloupe brain, brain mud, rough speed brain, muza brain, purity level and block size.

Demoted one by one."

"It's as good as the one made by Mingrun, but it doesn't fall into other grades. Why? Because the brain of Ruilong is like amber, and there is no one as pure as snow."

Su You couldn't help but admire Su Shi: "How come you know everything?"

Su Shi smiled and said: "But it's not as good as you. You can even get dragon brains at your fingertips."

Su You was funny: "Don't tell me you've tried it too."

Su Shi smiled bitterly and said: "I have really tried it. I heard the alchemist say that there is a country called Japan in the sea. The people there can burn the borneol into pieces by burning the leftover borneol wood fragments and sawdust into the water."

Seal the pot with a lid and bury it in hot ashes overnight, and a layer of brain will condense inside the lid, which can be obtained by scraping it off."

Su You nodded: "Actually, it's similar to my method, but my method can control the temperature from being too high."

Su Shi clasped his hands together: "That's the key! When I tried this method, all I got was a layer of burnt and smelly oil! It's not as good as the crystal you made. It's white in color and elegant in fragrance, even better than natural products."

After saying that, I couldn't help but stumbled: "It was almost, just a little bit close! Why didn't I think of using the steaming method?!"

Su You smiled and said, "When I tell you that, I'm embarrassed to sell it cheaply."

Cheng Wenying laughed loudly: "Don't! I claim to the outside world that I spent a lot of money on the movable type porcelain code, and Banniang almost lost her life for it. You have to preach to me like this when you go outside."

A group of foxes were all laughing.

Cheng Wenying added: "Now it's not a question of whether it's expensive or not, but whether it's available or not. The ink in my books is mainly tung oil, and the ink is mainly rubber. After adding this, Cheng Sheren's calligraphy and Cheng Sheren's ink will be ready immediately."

It can double your worth!”

After speaking, he hesitated and said: "That's good, that's good, but there's only one thing. This fragrant medicine is exclusively for the imperial court. My dear nephew, do you have any idea... Well, come up with an idea..."

Su You understood instantly, rolled his eyes, took a glass of alcohol, picked some crystals and put them into the glass. The crystals quickly melted into a clear solution, and the aroma in the room became more intense.

Su You spread his hands and said: "There is no more borneol. Now there is only Xianglu Kelong Xianglu."

Cheng Wenying slapped his thigh: "Wonderful, I know my good nephew has a way! Hahaha, I will give you a bottle of Shiguan for this fragrant dew, and what else... Kelong oil, that Liuguan, dissolve it for me

Oh... By the way, can I drink this wine?"

Su Shi also looked at the bottle of wine and salivated: "I heard that borneol is good for men. If men eat it, there will be many benefits..."

Su You rolled his eyes and was convinced by these two foodies. He quickly waved his hand: "This is pure alcohol! You can't drink it!"

After speaking, he covered his face with his hands and whispered: "Since it is medicine, if you insist on tasting it, you can try putting some Yongchun Dew in it, but not too much."

Su Shi said cheekily: "Mingrun, do you have any more? Give me some."

Su You asked: "What for?"

Su Shi said: "I learned a secret method from the alchemist: cut off the top of a quince, gouge out the heart, add sandalwood, agarwood powder, and a little musk deer. Cover the cut top, tie it with a thread and steam it till it rots. Take it out and let it cool.

, grind it like mud. Pour a little into the brain, mix well, and bake it into small cakes. The fragrance will not be reduced by the ambergris. 'When the incense is made, I will give you half of it."

Su You didn't believe it at all: "Tell me first, what is the success rate of these messy so-called secret methods that you have asked around?"

Su Shi thought for a long time: "It seems that none of them have been successful...ah, no, I succeeded in cultivating pine saplings! There is also alchemy. Well, you exposed it and said it was arsenic. I haven't tried that yet, but I hope you can try it.

Live the same..."

Su You smiled: "Okay, thanks to your perseverance in experimentation and long-term curiosity, I will make some for you tomorrow! By the way, Hachigong, what is this quince?"

Hachigong smiled and said: "Don't listen to Zizhan's talk of being so high-minded, the quince is the wood pear! You almost grafted that one off!"

When you talk about Su You, you will understand. As for the wood pear, the fruit can be smelled but not eaten. It tastes like wood dregs. In later generations, papayas, pears and apples were commonly used as rootstocks for grafting and dwarfing!

When he got up early the next morning, Mr. Su Da personally led the team and led the children to move the camphor tree leaves, and then personally operated the production of borneol. Then he and Cheng Wenying happily left with the fragrance all over their bodies.

After the awning boat trip, Su You suddenly remembered a question: "Hey! Zizhan, you just write everything in your notes! Scholars love to show off! Do you know that the process is confidential?!"

In the following days, the main work was to debug machine tools and forging machines with the Shi family.

Time entered the twelfth lunar month, and the first screw was completed on the lathe.

The exquisite thread made Su You very satisfied: "Now I announce that the first threaded screw in the Song Dynasty was born in Kelong!"

Shi Tong couldn't stop laughing: "Master, you are not right. If this is the first one, then where did the ones on the lathe come from?"

Su You had a black look on his face, and he went up and gave Shi Tong a kick: "Is it the same?! Can it be the same?! Yours is a fitter job, this is a lathe job!"

Even Shi Fu couldn't stop laughing now: "This blacksmith is so meticulous? He's almost like a doctor from the Five Classics!"

Su You was angry: "It's Dr. Hardware! This is an epoch-making product! You two are so, so incomparable!"

This time it was Li Shuanhao who led the group again, and even he couldn't help but be happy: "The young master is so awesome that I can't escape, but in this... era, it's boring to draw too much. The bricks and mud from last time

You have already painted it once, and you want to paint this iron rod again. It makes sense for you to paint it on the pile of gold-like bronzes over there..."
