After eating a few more oysters, Li Yi asked the palace maids to help his sister-in-law to rest.
Judging by the time they came, they would definitely stay for the night.
Before dinner, Li Longji 'inspected' the workshop.
In the glass workshop, they were blowing glass, light bulbs, and big bubbles.
After blowing the big bubbles, they were cut on a hot iron plate and pressed gently with a roller. A plate of glass appeared.
They also blew into a mold to make a glass bottle. When it was taken out, another mold was placed at the mouth of the bottle and rotated. When it was taken out, there were more lines.
Li Chengqi hid from the craftsmen and watched from the side. He said, "Who would have thought that the priceless glass outside could be made so easily?"
Li Yi didn't want to talk to someone who didn't value technology. What did he mean by easy?
Li Longji watched someone swing the blown glass around in a big groove on the ground in front of him.
The glass gradually became longer as it was blown and swung. When the temperature dropped a little, the person who blew the glass held a hollow long rod and put the glass bubble into the furnace diagonally outside to heat it.
Then, it was placed on an iron plate. Someone cut it with a knife. First, it was cut, flattened, and then cut it into small squares.
"This is a mirror." Li Longji recognized it.
A small piece was a mirror. Only the Empress had it in the palace. She could give it to whoever she wanted. It was as precious as it could be.
"Third Brother is right. If we don't cut it now, it will be damaged too much when the big pieces are cold." Li Yi looked at the glass and clenched his fists.
These were all ammunition for economic warfare. Soap and toilet water were used to attack first, then soap and perfume.
After the mirror, it would be pushed up layer by layer. The pursuit of luxury goods by the human race was the beginning of class division.
When using survival materials to exchange for luxury goods, the conflict would intensify.
That was why taxes were levied on the rich to subsidize the poor. Taxes were to protect the rich.
"Can you make telescopes?" Li Longji looked at the glass and suddenly asked about a key thing. Telescopes.
Back then, Yi Di said that he would use his lifespan to exchange for them. There were only ten. Brother Yi kept two, one for himself, and seven for the border army.
If he used his lifespan to exchange for them, he naturally couldn't ask for more. But if he didn't need his lifespan …
"Yes, but I can't do the finesse I showed you," Li Yi admitted.
"Brother Yi, hurry up. I will deliver it to His Majesty in your stead."
Li Longji was getting better and better at role-playing.
Calling him Your Majesty again and again didn't feel out of place at all. It sounded so natural.
"In a few days, there won't be any major battles at the border this year, so I'll make some myopia and presbyopia glasses of various degrees. Lens grinding requires a lot of technology. "
Li Yi did not mention the specific technology. He believed that Big Brother and Third Brother would not be willing to listen.
Li Longji felt a lot more at ease. It was fine as long as there were no major battles.
He left the glass workshop and moved to the manual stamping workshop.
The man pulled the gourd, and a large piece of iron was pulled up. Below it was a large iron plate, and there was a groove on the iron plate.
One by one, the iron pieces were placed on top of the lighter. With a clang, the big iron pieces fell down. The iron pieces became the iron box, the parts of the lighter's exterior.
The iron block was pulled up again, the iron box was taken out, and the iron plate was placed back in.
These iron boxes were sent to the next location and assembled with the boxes above and other parts.
The inner core was put in and painted.
The last step was to pour in some alcohol, take it far away, and try to ignite it.
"Fire sickle?" Li Chengqi was surprised.
After Gao Lishi and the others left, he and Li Longji came over. The lighter was not given to them yet.
Therefore, Li Longji was curious. Was it so easy to ignite a fire?
His finger slipped, and a flame came out and kept burning.
"Lighter, use alcohol. Big Brother and Third Brother brought some when they left. When the alcohol in the lighter is gone, come to me to refill it," Li Yi said.
"How much does it cost for others to refill it?" Li Chengqi thought of glycerin. The glass bottle of glycerin was given for free. Once the glycerin was used, it could not be stopped.
"Fire sickles are enough for ordinary people." Li Yi talked about another matter.
"As expected, the price is not cheap. Can ordinary spirits be ignited? "Li Chengqi was worried that the alcohol would not sell well.
"Absolutely not. The 50% alcohol we drank won't work either. Unless you use another lighter to light it," Li Yi said with a smile.
"Good stuff, I will give it away for you." Li Chengqi patted his chest and promised.
In the past, when he saw Li Yi giving things away, he would feel sorry for him.
Now that he did not, the more he gave away, the more Brother Yi would earn.
Li Longji thought of something else, "Brother Yi, you use grains to make wine?"
"Third Brother, are you saying that there is no imperial court …" Li Yi asked about the license.
"No, you can make wine if you want. I just want to know how much grain you use." Li Longji said.
"I use grains that are fed to livestock to make wine. Then, I add wheat straw and distilled it. The final distiller's grains can be fed to livestock. As long as the fermentation process can keep up, other things can be used to make wine."
Li Yi explained the situation. Nowadays, some people still eat distiller's grains in remote places. It was better to eat a little than to go hungry.
When making other dishes, he added distiller's grains, kneaded the dough, grabbed two handfuls of distiller's grains and threw them into pancakes and steamed buns.
The rest of the grains were also fed to livestock. It was impossible to throw them into the field as fertilizer.
"Can this method be spread out?" Li Longji was concerned about the matter of making wine.
"It can't be spread out. This wine is not good for people's health. It can only be used to fill lighters. I don't even dare to use it to treat patients. It needs to be purified again and again. After that, I will check if there are any other problems before it can be blended to 75%."
Li Yi refused. He dared to guarantee that if the method was spread out, there would be people who would make wine and sell it to people.
The wine had not been distilled and was filtered through cloth. Many things could not be filtered out.
"Then forget it." Li Longji did not insist.
He thought that if he used other things to make wine, he would limit the use of good grains to make wine and save on food.
After leaving, they entered the floral water workshop. There were all kinds of distillation equipment.
Even though the weather was cold, they had to open the doors to allow for ventilation. At the same time, they forbade anything with fire from entering.
They were worried that the alcohol in the air would be too strong and would explode.
Here, the smell was not good. They felt a little dizzy. After looking around, they stopped and rushed to the cafeteria. It was already time to eat.
Empress Wang washed her hands and waited. There were many fish in the cafeteria today.
They were fished out from the Ba River. Some of them were made into dried fish and some were directly turned into delicacies.
Some were fried with bread crumbs after all the bones were removed. Some were made into fish balls by smashing them into mud with a stick.
As for steaming and braising, they did not have any technical content.
"It's just that it's comfortable to eat in uncle's room." Empress Wang and the other two came back and said to Li Yi with a smile.
When she said comfortable, she meant that she felt relieved.
"Sister-in-law is right. Food is the most important thing for people. Food is the most important thing." Li Yi added.
"I ordered the biggest dish today, fish head stewed with tofu." Empress Wang made the decision and chose the main dish. What was on the table was what she wanted to eat.
