In fact, the best of these things should be high boron glass. After all, this kind of glass has very good heat resistance and thermal conductivity, and can be used to make condenser tubes, distillers, etc.
It's just that even if Zhao Feng can make glass, it's impossible to make glass with such high quality, so it's better to use the most traditional pottery.
Zhao Feng thought about using steel to make it, but then the cost would go up again. After all, the production of steel is not as developed as imagined. There are only the small engineering workshop he established before, and later Zhou Zhen Some places that have developed are using this method to make steel.
In fact, in many cases, a thing is limited in many ways, and a very classic barrel theory is used here.
How much water a barrel can hold is not determined by the longest board, but by the shortest board.
Even if their production methods have changed, their mining methods have not changed, and they cannot produce a large amount of steel.
Even if they change the way they mine, if they fail to find iron ore rich in iron ore, it will also limit their steel production.
Fortunately, these pottery is enough for now.
Zhao Feng arranged for people to build the brewery, and at the same time he was also studying how to brew wine.
Zhao Feng still remembered that he had seen the specific process of brewing wine in some wineries in later generations. Although it may not be so detailed, and the proportions and so on need to be explored by himself, the general process is not wrong.
In fact, many people in later generations have used industrial methods to make wine. People like Zhao Feng who use the pure grain solid state method to make wine can be considered top-notch wines.
For the next period of time, Zhao Feng kept trying, but something soon happened that made Zhao Feng very angry.
"Mr. Zhao, something is wrong. Our caravan has been robbed!"
Upon hearing this, Zhao Feng stood up instantly and looked at the caravan guard in disbelief.
"What did you say? How did you get robbed?"
"Are there any casualties?"
The guard shook his head and said with a sad face.
"We loaded up some paper and cloth, and when we were approaching those countries in the Western Region, some Huns' cavalry suddenly rushed out and robbed us."
"But they only robbed the fabrics, not the papers. They probably didn't know what the papers were used for."
Hearing this, Zhao Feng suddenly became furious.
In fact, when they transported these things, they also transported some to the Xiongnu.
However, there was no paper among the things sold to the Huns, only some cloth and wood, etc.
Unexpectedly, the Huns not only bought these things from them at very low prices, but now they actually wanted to rob them.
Zhao Feng gritted his teeth angrily and said to the guard.
"Okay, you don't have to worry too much, this matter has nothing to do with you."
"As long as the people are fine, it will be fine. When they come to rob you in the future, you will do the same. Even if you can't save the goods, you must protect yourselves as much as possible."
The guard felt moved in his heart. Not only did Zhao Feng pay them a lot of money, but he also cared so much about their lives.
While thinking this, the guard suddenly remembered another thing.
"By the way, Mr. Zhao, although the Huns robbed us of the fabrics, after we sold the papers, we found a few things that Mr. Zhao asked us to find before!"
Zhao Feng was stunned for a moment, suddenly surprised, and asked quickly.
"What did you find?"
The guard turned to say hello outside, and saw two caravan members walking in carrying a box.
They opened the box, and Zhao Feng quickly walked over to take a look, and instantly burst into hearty laughter.
"That's great. I didn't expect you to find this. It's a blessing from God!"
Seeing Zhao Feng so excited, the guards and caravan members also became happy. They were worthy of Zhao Feng's care for them.
Zhao Feng looked at the things in the box and said happily.
"This is a real blessing in disguise. This time I will reward you heavily!"
What these people brought back were actually some plants unique to the Western Regions, such as cotton, hot peppers, peppers, etc.
In addition, they actually found some barley and oats.
These are high-yield grains and are easier to grow than rice. The most important thing is that because Zhao Feng now plans to carry out selective breeding, he needs a variety of plants for hybridization.
The most important one is actually cotton. Zhao Feng remembered that the Western Regions actually had the experience of paying tribute to cotton in history. However, at that time, cotton was not used to keep out the cold, nor was it used for weaving. Used as an ornamental plant.
After the cultivation was promoted in the mainland, the genes of cotton changed to a certain extent, which increased the yield of cotton. And some people improved the method of cotton spinning and weaving, and cotton cloth appeared.
There are so many benefits of cotton. It is not only more delicate, but also warmer. The most important thing is that cotton can also be stuffed into the quilt to provide better protection against the cold.
It can be said that the appearance of these things gave Zhao Feng greater confidence.
After asking people to take down all these things and keep them well, Zhao Feng thought about how to punish the Xiongnu people.
The supplies they sold to the Huns also included some salt. After all, there was not that much salt on the grasslands, so the Huns had to buy a lot of salt from them.
Ever since the Li family produced snowflake salt, the salt of the entire Zhou Dynasty was almost monopolized by the Li family. Since other salt merchants did not have a method to purify edible salt, they were all purchased by Li Jia one after another.
At the beginning, Zhao Feng did not expect that Li Wanyi, who had been wiped out, could be so aggressive in business. Not only did she rely on her own talents to make the Li family grow bigger and bigger, but now she had become the largest salt in the Zhou Dynasty. Business also allowed the Li family to own a lot of salt mountains.
Thinking of this, Zhao Feng suddenly thought of a good idea.
So he wrote a letter directly, inviting Li Wanyi to come to the capital, and planned to talk to Li Wanyi about this matter in person.
After writing the letter and sending it off, Zhao Feng narrowed his eyes slightly. Since the Huns had provoked him, he had to advance his plan.
Soon, after receiving Zhao Feng's letter, Li Wanyi directly followed the caravan transporting salt to the capital.
"Mr. Zhao, long time no see. How are you?"
Li Wanyi also looked like a strong woman at this time. Although she still had the temperament of Xiaojiabiyu, she spoke and acted more resolutely than before.
