Primitives are stunned

Chapter 219 Lost Wax Method

After lunch, Wang Hao went to the construction site to have a look.Since the wooden wall was built, the main energy in the village, except for reclaiming the land, has been put on building the house.

Originally, this matter was left to Gu Mu to look at, but these few days, Gu Mu was too weak and was recovering, so Wang Hao had to care about it.

The first batch of houses built are two rows of small bungalows side by side. The foundation can be filled in these two days, and the laying of bricks will start soon.

These two rows of houses, in Wang Hao's plan, one row is used as a warehouse, and the remaining row is used for living.

The workers are very motivated, because in their view, the three brick houses in Wangcun are simply a miracle, and they are now participating in a miracle.

Of course, there are also some heads of various villages, whose eyes are flickering.They can't wait to build a house.What they are most afraid of now is that when Wangcun builds a house, they will be squeezed out, so that they cannot see the whole process of building the house.

For their little thoughts, Wang Hao understands clearly.He now hopes that some smart people will come out of these out-of-village people and learn this technique as soon as possible.

The construction of Hwaseong could not be completed by relying on their village alone.The power of the entire Great Wilderness must be mobilized.

After solving a few problems on the construction site and correcting some mistakes, Wang Hao went back.

Wang Long stood in front of the plaster ball every step of the way, his cautious appearance made Wang Hao feel a little funny.

They couldn't understand what Wang Hao did. Wang Long once asked Wang Hao what he was doing.

Then Wang Hao patted the Haotian Sword on his waist and told him that it was a metal that could only be made by making this kind of ancestor god.

Wang Hao looked and found that these plaster balls had been dried under the scorching sun.

Picking up a plaster ball casually, Wang Hao cut it with a knife.

The gypsum chips fell down one after another, until Wang Hao saw a smear of light blue tree wax through the thin layer of gypsum through the hole he cut out.

Because it wasn't too delicate, Wang Hao wasn't too careful. When he chipped out a little tree wax from the small hole, he stopped.

Following his example, Wang Long also took out his knife and began to cut it.

Soon, when the gypsum balls were all processed, a member of the tribe also came over and asked Wang Hao that the copper furnace had been heated, and whether to add materials now.

After giving them an affirmative answer, Wang Hao asked someone to pull the processed gypsum balls to the vicinity of the copper smelting furnace.

The lost wax method, as the name suggests, will definitely not have wax in the end.

These gypsum balls had already solidified. Next to the copper smelting furnace, Wang Hao and the others lit a fire and put these gypsum balls into the fire to bake.

Gypsum has high fire resistance, and this temperature will not change it.But tree wax is different.

Under high temperature, the tree wax in the gypsum quickly melted into a liquid state. At this time, the tree wax inside was poured out along the small hole that was originally opened, and a mold that could be used for pouring was made. .

In the evening, the tin and copper in the furnace melted and fused together.

Open the valve, and the bronze water will flow into the crucible.

Wang Long held the crucible with pliers, and carefully poured it into the funnel controlled by Wang Hao, and the tip of the funnel was facing the small hole made by a fixed plaster ball.

Like the pliers, this funnel is also a tool made by the system. Otherwise, according to Wang Hao's current technology, there is no way to make a funnel that can withstand the high temperature of molten steel.

In the eyes of the savages, Wang Hao himself sealed the power of those flames in each of the stone balls.

Some of them even thought about how powerful such a stone ball would be if it exploded.

Soon, more than 60 molds in this row were poured by the two of them.

Wang Long shook his hands, not because he was tired, but mainly because he was too nervous during this time, for fear that the copper water containing high temperature would spill a little.

Wang Hao's half-baked level doesn't know that the lost-wax method is actually a very extravagant method.Because a mold, once used, cannot be used again.

The reason why he chooses this method is mainly because his friend’s small workshop makes sword hilts that are relatively fine items, and they often carve some fine things according to the requirements of customers, so he uses this method. method.

In fact, in ancient times, these rough casts did not require any finely-operated agricultural tools, and most workshops used stone models that could be used repeatedly.

By dinner time, the gypsum balls were still exuding suffocating heat.

Wang Hao didn't use water cooling. After all, in terms of casting, he only went to help others for a few days, and he was basically in the position of Xiaobai.

He remembered that friend once said that if the ratio of materials is not handled properly, water cooling may cause the utensils to crack or even explode.

He doesn't know what the specific ratio is, so he can only try it out later.

Although the temperature has not come down, the copper water in the gypsum has solidified.

I found a wheelbarrow, put the plaster balls on with pliers, and brought them back to the village.

After dinner, more than ten people followed Wang Hao to the house where the plaster balls were stored.

Wang Long was inside, Gu Mu and Shi Li followed behind, Wang Hu, Wang Zhu and the others followed, and even Wang Erniu and several clan elders also came.

It can be said that the most important group of people in Wang Village, or the group of people with the greatest power, except Wang Ba who trained the captives in Yan Village, the rest are here.

When he came to the room, Wang Hu recognized the dozens of plaster balls on the ground at a glance.

He knew that those gypsum balls were filled with various things carved out of tree wax by people like himself.

There are hammers, axes, and heads.

Except for Wang Long, basically no one else understood why Wang Hao brought them to see these things so carefully. Even Gu Mu, who was helped over, didn't know what kind of officials Wang Hao was selling.

Looking at the puzzled crowd and Wang Hu who was poking his head, Wang Hao handed a small hammer to Wang Hu, and said, "Huzi, go find a plaster ball and break it into pieces."

Wang Hu was puzzled. He was building a house in the afternoon and did not participate in the casting. He had no idea what Wang Hao wanted to do.

However, regarding Wang Hao's words, he unswervingly carried them out.

Randomly picking one out of the plaster balls, Wang Hu squeezed his ears, and said with a surprised face: "Ah! Hao, this is still a bit hot!"
