"Raw materials, beef and mutton fat, lard, asphalt, rosin..."
"Spice, vanilla oil, rosin oil, wintergreen oil, osmanthus oil, cinnamon oil..."
"Oil processing, pressing, filtering, cooking, saponification..."
Li Ang used more than a dozen pieces of paper in a row to write down the soap and soap making process in as much detail as possible, from the selection of raw materials, to the production of production tools, to the protective equipment that workers need to use, and even the production of waste materials, waste residues, and waste water.
Processing, all available.
The handicraft industry in Yu State is relatively developed. In places such as Chang'an, Luoyang, Suzhou and Hangzhou, workshop owners have purchased land, placed looms, and hired workers to mass-produce fabrics.
The number of workers ranges from dozens to hundreds or thousands.
It brings a large amount of tax revenue to Yu State every year. And with detailed industrial drawings, it is not that difficult to switch to soap production.
"This is the benefit of being a disciple of the Academy.
You don’t need to come out in person to socialize with the heads of big companies, and you don’t have to worry about your money being swallowed up. You just have to sit back and wait to receive the money.”
Li Ang said: "Moreover, the Academy has mastered the violence itself and the absolute right to speak. No matter how greedy the workshop owners are in pursuing profits, they must restrain themselves when facing the Academy, otherwise the patents will be withdrawn and past earnings will be recovered.<
/p>
To a certain extent, workers’ rights and interests can be protected..."
Li Ang read the drawings several times, checked for omissions and added more instructions on how workers should protect themselves during the production process. Then he put down the pen, waited for the ink on the paper to dry, and then put the paper back in the drawer.
Prepare to submit it to the Patent Office when you return to the Academy the day after tomorrow.
The patent he is planning to register this time includes not only soap, but also absorbent cotton - absorbent cotton is hygienic and clean, and can be used as disinfectant cotton balls when soaked in pure wine. It can also be used to stop bleeding, so it will definitely sell well as a monthly product.
Moreover, absorbent cotton is also one of the raw materials for nitrocellulose...
"Soap and absorbent cotton are daily necessities and fast-moving consumer goods. They are consumed much faster than midwifery forceps. The profits they bring are also much higher than public welfare midwifery forceps."
Li Ang looked up at the curious Chai Cuiqiao and smiled: "We will be rich soon."
"Ah, really?"
Chai Cuiqiao was pleasantly surprised at first, and then asked doubtfully: "But doesn't selling cotton cloth made of absorbent cotton..."
"This time, that time."
Li Ang shook his head helplessly and said: "The emperor and empress have already planned to publicize the midwifery forceps, and the title of gynecological master will never go away.
Simply sell the manufacturing process of absorbent cotton, which can also benefit the country and the people and improve people's livelihood.
As for the impact...at worst, I can ask the doctors at the patent office to help hide my real name."
Money is not everything, but nothing is impossible without money.
Li Ang needs a lot of money to buy special materials, conduct experiments, or feed Mo Si.
‘The only problem is, how can I buy large amounts of gold and silver for a reasonable reason?
In big cities such as Chang'an and Luoyang, the use of flying tickets for large transactions has become quite common. Gold and silver are used less and less as currency.
A large number of acquisitions in a short period of time will certainly attract attention.’
Li Ang thought silently: 'The reason for using it before was to make surgical tools - this is reasonable, after all, the medical community of Yu State has gold and silver needles.
With a larger amount, the surgical tools will not be enough.
How about buying gold and silver in batches? Hide your identity and buy a few more times, only a small amount each time.
Or create yourself a money-loving character who loves collecting gold and silver ingots?’
Judging from the amount of silk required, even if you earn hundreds of thousands of dollars a day, you can still digest it.
‘Forget it, let’s wait until we get the first money.’
Li Ang shook his head. There are many ways to make money from patents, that is, they can be sold to large companies permanently for tens of thousands or hundreds of thousands of dollars at a time.
You can also authorize a designated trade name for ten or twenty years. No patent fees will be charged to the trade name during these twenty years.
You can also license it to all companies that want to produce goods at a low price, and the little you add up makes a big difference.
"The scale of operation and production of large companies far exceeds that of small and medium-sized companies. The logic of Xuegong Patent Office is that the more goods are produced, the more patent fees will be paid. After a little calculation, large companies will agree to adopt a ten-year or twenty-year patent licensing policy.
Plan."
Li Ang said: "This should be the fastest way to make the most money - besides writing talismans."
Dong dong dong.
A knock on the door sounded outside the courtyard, and Yang Yu's voice came, "The sun is rising, the moon appreciating group is about to start! Get ready to go."
"So soon? Didn't you say it would be evening?"
Li Ang walked to the courtyard with some surprise and opened the door. Outside the door were parked the carriages of Yang Yu and Yong Hongzhong's family.
"The carriage is ready."
Yang Yu pointed to the empty carriage behind him, rubbed his palms and said excitedly: "There are too many people going there today. Go there in advance to avoid having to squeeze in with others. Have you brought your tickets?"
"Bring it."
Li Ang asked Chai Cuiqiao to go to the study and bring two tickets. After closing the courtyard door, he got on the carriage and headed to the West Market.
Along the way, many horse-drawn carriages can be seen heading towards the West Market. The convoy drove through Liquanfang Street, entered the West Market Archway, passed the building complex, and came to a theater pavilion.
There were Goulan tile houses in the big cities in the early Yu Dynasty. At that time, they were still temporary tile-roofed houses and shacks where actors performed operas and dramas.
As time went by, it gradually evolved into a formal stage theater, covering an increasingly larger area, with more luxurious interior and exterior decorations, and private rooms for distinguished guests.
"Arrived."
The carriage stopped in front of the largest pavilion called "Luoyang Tower". Yang Yu jumped out of the carriage excitedly and called for Li Ang and others to follow.
There were a lot of people queuing up outside the theater. Yang Yu should have asked his servants to wait in front. It didn't take long before he brought Li Ang and others to the entrance of the theater and handed four tickets to the man wearing a half-arm costume and Zhou Guodian's round figure.
Hat's doorman.
"Please come in, Mr. Yang Xiaolang from the Academy."
The tall and round guard has a respectful attitude and speaks fluent Chang'an Mandarin, with an almost indistinguishable Zhou accent.
This chapter is not over yet, please click on the next page to continue reading!
Li Ang and Chai Cuiqiao followed Yang Yu, looking left and right at the decorations inside and outside the theater.
At the entrance of the theater, there is a wooden sign named "Zhaozi", which says what play will be performed today and the names of the famous actors - that is, Jian Yue Theater Troupe.
In addition, there are colorful flags hanging on the wall, which list the famous theater companies that have performed in this theater in history. It is equivalent to historical honor.
"Like those fine restaurants, there are cooling charms posted to balance the temperature. There are also... light notes posted on the ceiling of the auditorium?
It is probably used to reduce the noise in the auditorium and maintain the stage atmosphere. It is quite professional."
Li Ang and Chai Cuiqiao were talking quietly when they suddenly heard shouts from ahead.
"Can you read the road? I'm covered in dust. Do you know how much I paid for this piece of satin?!"
A middle-aged man with a wide body and a fat body was scratching his neck, patting the dust and fruit crumbs on his brocade clothes, and at the same time angrily scolding the boy wearing the clothes of Jian Yue Troupe.
The boy kept nodding and apologizing, smiling, and behind him stood an old woman holding a broom and dustpan with a slightly dull expression.
The performance was about to start in a while, and the staff of Jian Yue Theater and Luoyang House talked hard, offered tickets and apologized, and persuaded the man in brocade to go back and calm down the storm.
At this time, Yang Yu had already found his seat, stood there and waved, "The sun is rising, the green leaves are rising, this way."
"Oh."
Li Ang and Chai Cuiqiao turned their heads, walked towards Yang Yu, and took their seats.
The originally crowded corridor started to be crowded again. The boy from the Jian Yue Troupe breathed a sigh of relief, turned around and whispered to the old woman holding a broom and dustpan: "Grandma, you go back first. It's fine now."
"..."
The old woman in gray clothes opened her mouth, her expression still a little dazed, and walked quietly to the backstage of the theater accompanied by the servant.
The citizens of Yu State were not surprised when they saw this scene. Many large theater troupes would spend money to support the elderly in their former theater troupes.
The old woman in gray clothes was walking towards the backstage of the theater. The skin on the tip of her index finger, which was covered with calluses, cracked quietly and slowly, and a drop of blood seeped out from it.
Tick tock.
Blood drops fell on the thick red carpet of the aisle and disappeared quickly.
