A lot of bronze heads have been cast, because until now, the heads and shovels are still the main tools used by the Qingque tribe to plough the land.

At this time, there is bronze, and when casting agricultural tools, it is natural to cast a batch of bronze pickaxes first.

As for the bronze ploughshare, a suitable mold has not yet been made, so we have to wait for it later.

First cast a batch of bronze pickaxes and bronze shovels to deal with the spring ploughing in the coming year, the bronze ploughshares and the plough wall, let Heiwa study slowly.

Compared with bronze ge, arrowheads, and pickaxes, axes, and knives, the '>' shaped, hollow plowshares, which are used to fill wood into them, are much more difficult to mold.

Simply use clay to make a model, and then print on the clay is no longer possible, and the mold needs to be transformed and upgraded.

For more than a month, Heiwa has not played much happily with Zhuang for this matter, and has been thinking about how to make the mold of the plow every day.

Han Cheng actually knows a rough idea, which is what is often called 'model'.

This kind of hollow appliance is no longer something that can be made by a single mold, in addition to the mold, it is also necessary to make a 'fan' out.

For example, to make a round bronze jar, with only one mold, the only thing that can be poured is a jar-shaped copper ingot.

If you want to pour a jar, you need to put another mold inside the mold, and this mold is called 'fan'.

Because with the word "model", it is possible to create something that has the same shape as previously imagined, and later the word "model" leads to the meaning of other aspects.

For example, the '359th Brigade' in the Nanniwan Wasteland is a model. ’

The reason why Heiwa is so melancholy that she loses her hair and doesn't even do her favorite sport much is because Han Cheng didn't tell Heiwa about the 'exemplary'.

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

So the matter was put down.

Bronze is used as a tool for farming, and according to archaeological data, it was not too much in ancient times.

Because most of the unearthed bronzes are ritual vessels, weapons, and a variety of food-related plates and bronze wine bottles, there are few agricultural tools among the burial goods.

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

After all, when bronze appeared and applied in large quantities, agriculture had become the mainstream, and as a country that has always paid attention to agriculture, it was impossible to ignore such a good material as bronze.

The reason why in later generations, there are few bronze farm tools in the unearthed cultural relics, in Han Cheng's view, is nothing more than the following reasons.

First, those who take bronze farm tools to do farm work are all lower-class savages or slaves, as they do not have much property, bronze farm tools are such useful and precious things, when they die, they are naturally reluctant to use them for burial, and most of them will choose to pass them on to their descendants.

The second is that those who can have a lot of funeral goods after death are basically nobles with high status and status, as well as a lot of wealth.

As aristocrats, only a series of bronzes such as tripods, bells, bottles, and bottles can match their status, and as for the bronze farm tools that are mostly used by the lower class untouchables, they will not be used for burials.

Savages or slaves were reluctant to use bronze farm tools for burial, and the nobles disdained to use bronze farm tools for burial, so there would not be too many bronze farm tools unearthed in later generations.

Therefore, it will also give people the impression that in the Bronze Age, bronze agricultural tools were not used much.

Regardless of whether his guess is right or not, there were not many people who used bronze as agricultural tools in ancient times, and Han Chengdu will unswervingly develop and popularize bronze agricultural tools in the tribe.

He won't let go of such a farming weapon.

As for the bronze ritual instruments such as tripods, bells, and chimes, it depends on the degree of development of the tribe and the need to decide.

Anyway, right now, it won't be in his consideration.

The lame carpenter was not idle, and at this time, together with a few people who had followed him when he was fine, he was removing the handle from the stone head and loading it on the bronze head.

This is not such a difficult thing to do for a craftsman like Lame.

You only need to put the thicker end of the wooden handle into the hole of the bronze head, and stick it to the place where there is an arc on the upper part of the hole.

Then make 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 is facing up, the grooved side is facing down, and the middle groove is just stuck on the edge of the hole.

Then make a thicker and longer piece of wood, thin in the front and thick in the back, stuff it between the two, find an axe and nail it into it a few times, and the wooden handle is firmly connected with the bronze pickaxe.

It is best to fix the handle of the head in this way, because if you do not do so, it will be extremely difficult to find a wooden handle as thick as the size of the hole.

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

More than half of the people who smelt copper and cast bronze are slaves, and it makes no sense that at this time, the citizens of the Qingque tribe are casting bronze in the wind and snow, but the slaves are roasting in the room to hide from the fire.

In fact, the slaves in the room were not very idle, some of them were spinning twine into thin threads with thread tops, and some were weaving cloth with simple looms.

Weaving slavery was not carried out in the slave courtyard, but in the machine room within the courtyard of the Qingque tribe.

This was to prevent the slaves from having too many materials in the small yard, and at the same time to reduce the destruction of the means of production by slaves.

Although up to now, there have been no such things as slaves destroying production tools in the Qingque tribe, but it is still necessary to pay attention to it.

The engine room used by the slaves was built separately, and in order to distinguish it from the machine room used by the citizens of the Qingque tribe, it was made of mud walls and grass roofs.

The loom is the same, this thing can't be made out of three, six, nine, etc., after all, the best cloth of the Qingque tribe so far is far from catching up with the woven cloth of later generations.

After kissing his cub's chubby face twice, Han Cheng, who had been walking around inside and outside the tribe, made a decision.

After thinking about it in his heart for a while, he went to find the witch who was on the kang, carrying a female rabbit's ears, feeding the mouse cubs like a mouse cub, and had not yet opened his eyes to feed the little rabbit cubs, and went to talk about this matter.

This matter is that he is going to let the long legs who have risen from a slave to a first-level citizen of the Qingque tribe to manage the slave courtyard.
