A lot of bronze hoes were cast, because to this day, hoes and shovels are still the main tools used by the Qingque tribe to plow the land and open up wasteland.

At this time, bronze was available, and when casting farm tools, it was natural to first cast a batch of bronze hoes.

As for the bronze plowshare, a suitable mold has not yet been made, so we can only wait and see.

First, a batch of bronze hoes and bronze shovels will be cast to cope with the spring plowing next year. As for the bronze plowshares and plow walls, let Heiwa study them slowly.

Compared with bronze spears, arrowheads, hoes, axes, and knives, the mold for the '>'-shaped, hollow plowshare used to load wood is much more difficult to make.

Simply making a model with clay and then printing on the prepared clay is no longer feasible; the mold needs to be modified and upgraded.

Over the past month, Heiwa stopped playing happily with Zhuang because of this matter. Every day he was thinking about how to make the mold of the plowshare.

Han Cheng actually knew a general idea of ​​the method, which is what is often called "model".

This kind of hollow utensil cannot be made with just a mold. In addition to the mold, a "mold" is also needed.

For example, if you want to make a round bronze pot, if you only use one mold, the only thing that can be cast is a pot-shaped copper ingot.

If you want to cast a pot, you need to put another mold inside the mold. This mold is called a "mold".

Because with the "model", something can be cast in the same shape as previously imagined. Later, the word "model" was extended to mean other things.

For example, the 359th Brigade was a model in the Nanniwan reclamation.

The reason why Heiwa was so depressed that his hair fell out and he even stopped doing his favorite sports with Zhuang was because Han Cheng did not tell Heiwa about the "model" matter.

At the beginning, Han Cheng wanted to see how long it would take Heiwa to solve the problem. After waiting for a while, when he wanted to speak, he found that Heiwa had already made some progress.

So the matter was dropped.

According to archaeological data, bronze was not widely used to make agricultural tools in ancient times.

Because most of the bronze artifacts unearthed are ritual vessels, weapons, and various food-related plates, bronze wine jars, etc., there are few agricultural tools among the burial objects.

However, Han Cheng felt that in ancient times, the number of bronze agricultural tools should not be too small.

After all, when bronze ware appeared and was used in large quantities, farming had become the mainstream. As a country that has always focused on farming, it is impossible to ignore such a good material as bronze.

In Han Cheng's opinion, the reason why there are few bronze agricultural tools among the unearthed cultural relics in later generations is nothing more than the following reasons.

First, those who used bronze farm tools to do farm work were all lower-class savages or slaves. As they did not have much property, they were naturally reluctant to use such useful and precious things as bronze farm tools as burial objects when they died, and most of them chose to pass them on to their descendants.

The second is that those who can have many burial objects after death are basically nobles with very high status and position, as well as a lot of wealth.

As nobles, only a series of bronze wares such as tripods, chime bells, jars, and bottles could match their status. As for bronze farm tools which were mostly used by the lower class untouchables, they would not use them as burial objects.

Savages or slaves were reluctant to use bronze farm tools as burial objects, and nobles disdained to use bronze farm tools as burial objects, so not many bronze farm tools were unearthed in later generations.

Therefore, people have the impression that bronze agricultural tools were not widely used in the Bronze Age.

Regardless of whether his guess is right or not, or whether bronze was used to make many agricultural tools in ancient times, Han Cheng will unswervingly develop and popularize bronze agricultural tools in the tribe.

He would not let go of such a great farming tool.

As for bronze ritual musical instruments such as tripods, bells, and chime bells, the decision will depend on the tribe's level of development and needs.

Anyway, it is not within his consideration now.

The lame carpenter was not idle either. At this time, he and a few other people who had nothing to do were helping him by removing the handles from the stone hoes and attaching them to the bronze hoes.

For a craftsman like Lao, this is not a difficult task.

Just put the thicker end of the wooden handle into the hole of the bronze hoe, and stick it to the arc part at the top of the hole.

Then get a small piece of wood with a groove in the middle on one side and a flat side, and place it on the side below the hole.

The flat side faces up and the grooved side faces down, with the groove in the middle just fitting over the edge of the hole.

Then get a thicker and longer piece of wood that is thin at the front and thick at the back, and stuff it between the two. Then find an axe and nail it hard a few times, and the wooden handle will be firmly connected to the bronze hoe head.

It is best to use this method to fix the hoe handle, because if you don't do this, it will be extremely difficult to find a wooden handle that is the same thickness as the hole, and it will also be difficult to make it secure.

Of course, when doing this, you need to pay attention to the angle between the wooden handle and the hoe head. It should not be too large or too small.

More than half of the people who smelted copper and cast bronze ware were slaves. It didn't make sense that while the citizens of the Qingque tribe were casting bronze in the wind and snow, the slaves were sitting in their rooms warming themselves by the fire and doing nothing.

In fact, the slaves in the room were not idle either. Some of them were using spinning tops to spin hemp ropes into thin threads, while others were weaving cloth on simple looms.

The slaves who wove did not work in the slave yard, but in the machine room inside the courtyard of the Qingque tribe.

This was to prevent the slave yard from having too many supplies, and was also a way to reduce the chances of slaves destroying the means of production.

Although up to now there has been no incidents of slaves destroying production tools in the Green Bird tribe, we still need to pay attention to it.

The machine room used by the slaves was built separately, with mud walls and thatched roofs to distinguish it from the machine room used by the citizens of the Green Bird tribe.

It’s the same with the loom. This thing cannot be ranked into different grades. After all, the best cloth produced by the Qingque tribe so far is far inferior to the machine-woven cloth of later generations.

After kissing his kid's chubby face twice, Han Cheng walked around the tribe and made a decision.

After thinking it over for a while, he went to find the witch who was lying on the kang, holding a mother rabbit's ear and feeding the little rabbit, which had not yet opened its eyes, like a baby mouse, and told her about this matter.

What he was going to do was to let Changtui, who had just been promoted from a slave to a first-level citizen of the Green Bird Tribe, manage the slave yard.
