Chapter 37 The First Pot of the Great Qin Dynasty
Recalling the bad environment in the Central Plains region in his previous life, Zhao Si was somewhat embarrassed.

Times have changed and times have changed. The difference between ancient and modern times is not only customs and systems, but also the difference in environment is huge.

Seeing that the sky was getting late, with the current temperature, it might take several days to dry out the salt water even in Zhengxia. Zhao Si didn't want to wait, and walked towards Wang Li's barracks with ease.

After having a hot pot meal with Wang Li before, Zhao Si and Wang Li got to know each other well.

Zhao Si suffers from lack of ingredients and seasonings.

Wang Li has no seasoning, no cooking methods, and no ingredients.

The two of them are both old gourmets, and they hit it off immediately, and they simply became a meal partner. Zhao Si was in charge of cooking the ingredients, and Wang Li was in charge of providing the ingredients.

Not to mention that Wang Li is a big dog, this guy said that he can't kill the farm cattle without authorization, basically he can get beef to eat every day.

When they arrived at the place, Wang Li's people hadn't come yet, so they didn't know what to do, but the servants were there, Wang Li ordered them to offer snacks and buttermilk without Zhao Si's asking.

It is worth mentioning that the army of the Qin Dynasty could bring slaves into the army.

To be precise, for those who have slaves at home, the conscription of the Qin State is conscripted with the slaves at home.

The situation of slave soldiers is more complicated. Some can follow their masters back and forth, while others are conscripted as auxiliary soldiers.

If a slave kills the enemy and makes meritorious service, Qin Law has a reward. There is no distinction between official slaves and private slaves. As long as the credit is sufficient, they can be released from slavery.

The Qin Dynasty was already in a slavery society, and the number of slaves was not small. Official and private slaves were an extremely large group, not much less than self-cultivating farmers.

While drinking buttermilk and eating snacks, Zhao Si felt a little nostalgic for the technology and hard work of modern society.

Wang Li really has no shortage of ingredients, he can even get bear paws, all kinds of wild game, as long as he asks for it, there will be no problem.

But the problem is that Zhao Si doesn't have enough seasoning, and his cooking skills are not superb, let alone there is not even a frying pan in this era.

The wok seems to have no technical content, but the industrial level required to make it is really not low.

First of all, it should not be too thick, too thick will affect the thermal conductivity.

Secondly, it should not be too brittle, if it is too brittle, it will shatter when fried.

Then it can't be too soft, and it will deform at every turn.

The popularization of iron pots to millions of households firstly required a large-scale increase in steel production, and secondly meant that iron and steel smelting technology reached the peak of the feudal era.

The current Qin Dynasty is still dominated by bronze wares, and iron wares are generally brittle, and it is difficult to make daily tools, let alone iron pots.

"So, how did the iron and steel smelting work?" Zhao Si frowned.

This thing really involves his knowledge blind spot, who has nothing to learn this?What Zhao Si knew was that the carbon content affected the quality of steel, and he didn't know how much it was. He didn't even remember the melting point of iron.

It is necessary for the general trend to replace bronze with steel. There is no way. The difficulty of mining iron ore is much lower than that of copper ore. Secondly, the reserves of iron are much higher than the reserves of copper.

Finally, the quality of the pinnacle steel armor weapons in the feudal era is far superior to the pinnacle bronze.

The problem lies here, the Qin Dynasty is already at the pinnacle of bronze wares.

And steel smelting doesn't even count as an introduction...

The technology tree here is already full, and the technology tree over there has just sprouted. If there is no large-scale government investment in steel smelting, the technological progress will be painfully slow.

Iron wares gradually replaced bronze wares in the Han Dynasty. A large part of the situation was that there were fewer and fewer copper mines, and it became more and more difficult to mine. In addition, a large number of bronze wares, gold and silver were buried with them, and copper had to bear the currency attribute, which was not enough at all. Go to the iron technology tree.

Of course, there is the most critical question.

Technology fault!
The level of bronze smelting in the Qin Dynasty was almost the peak of the Bronze Age. At the end of the Qin Dynasty, the smelting technology regressed and key technologies and systems were lost. This was also an important reason why the Han Dynasty had to start the iron technology tree.

Although the Qin Dynasty also faced these problems, it was not as severe as the Han Dynasty. After all, this era was relatively primitive and commerce was not developed.

Although bronze is expensive and rare, it is barely enough at the national level.

As for iron and steel, with the current difficulty in smelting and the eye-popping practical level, for the first emperor, it is better to continue to study bronze smelting, hoping to find larger copper mines and more advanced smelting technology.

But Zhao Si knew that the Qin Dynasty's bronze smelting technology had come to an end, and it would be the same if it went up.

It's a pity that if you want to open another steel branch line in this era when the quality of bronze ware is at its peak and the quantity is barely enough, you need a lot of courage.

Iron and steel smelting is not like papermaking, just find a few craftsmen and you can figure it out slowly.

The investment in this thing is outrageous, and it has to be a large-scale investment by official institutions, starting from the source industries such as iron ore.

And it is very likely that it will face negative returns for a long time.Great financial burden.

There is no doubt that the early iron ware is absolutely inferior to the bronze ware.

"I don't know if Emperor Shihuang has the courage to carry out industrial transformation. This thing is really beneficial for thousands of years!" Zhao Si thought about it, and someday he would tease Emperor Shihuang, so he said that.

Iron and steel smelting technology has not developed, many things can not be done, the performance of steel is much higher than that of bronze, this is a fact.

He was thinking about how to persuade Shi Huangdi to invest a large amount of money, but he saw Wang Li walking towards with a bronze pot in his hands with a happy face.

"The pot you mentioned, I sent someone to get it out!" Wang Li patted the bottom of the pot beamingly and said with a smile.

Thanks to Zhao Si's heart-wrenching cooking, Wang Li complained to Wang Li that there was no pot in Daqin. Wang Li kept it in mind. Si's description made a copper pot.

When Zhao Si started, it was too heavy.

However, the thickness is moderate, not particularly thick, but it can't be particularly thin.

Bronze is brittle and cannot be made too thin. It is naturally thicker than iron pans.

The copper pot that Wang Li obtained is already very good. Although it may affect the thermal conductivity, it is not a big problem. With full firepower, can the pot still be cold?

However, it is obvious that this copper pot is of great value and exquisite craftsmanship, and it is impossible to mass-produce it in this era.

Ordinary families may not be able to afford this pot with the money they earn from a year of hard work.

This is real copper, the kind that can be melted directly into money.

But for Zhao Si, there is no serious problem!
After all, Wang Li was a rich man of three generations, so he didn't need to consider the cost issue at all. He lightly stroked the exquisitely crafted copper pot, and Zhao Si showed joy on his face.

At this moment, several dishes had already appeared in his mind.
