Chapter 218: Lost Wax Method

After lunch, Wang Hao first went to the construction site to take a look. Since the wooden wall was built www.biquge.info the main energy in the village, in addition to cultivating the land, the rest has been put on building houses.

Originally, this matter was handed over to Gu Mu to see, but in the past few days, Gu Mu was too weak and on the way to recovery, so Wang Hao had to care about it.

The first batch of houses to be built were two small bungalows side by side, and the foundations could be filled in two days, and soon the bricks would be built.

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 opinion, the three brick houses in Wang Village 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 flashing. They can't wait to build a house. What they are most afraid of now is that when Wang Cun builds a house, they will be excluded from it, so that they cannot see the whole process of building the house.

For their careful thinking, Wang Hao understands it clearly. He now hopes that a few smart people from these other villages can come out and learn this technique quickly.

The construction of Hwaseong could not have been completed by their village alone. It is necessary to mobilize the power of the entire Great Wilderness.

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

Wang Lung kept in front of the plaster ball inch by inch, and that cautious appearance made Wang Hao feel a little funny.

They couldn't understand everything Wang Hao did, Wang Lung once asked Wang Hao what he was doing.

Then Wang Hao patted the Haotian Sword on his waist and told him that this was making this kind of metal that only ancestral gods could make.

Wang Hao looked at it, and under the scorching sun, these gypsum balls had been dried.

picked up a plaster ball casually, and Wang Hao sharpened it with a knife.

Pieces of plaster fell, until Wang Hao saw a touch of pale blue tree wax through a thin layer of plaster through the hole he had cut out.

Because it wasn't something too delicate, Wang Hao wasn't too careful, and when he cut out a little bit of tree wax from this small hole that was big at the top and narrow at the bottom, he stopped.

Following his example, Wang Lung also took out a knife and began to sharpen it.

Soon, when the gypsum balls were all processed, a clansman also came over and asked Wang Hao if the copper furnace had been heated and whether he would add it now.

gave them an affirmative answer, and Wang Hao found someone to pull the processed gypsum balls to the vicinity of the copper smelting furnace in a car.

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

These gypsum balls have solidified, and next to the copper smelting furnace, Wang Hao and the others made a fire and put these gypsum balls into the fire to bake.

Gypsum is highly resistant to fire, and this temperature does not change it. But tree wax is different.

At high temperatures, the wax in the gypsum quickly melts into a liquid state, and at this time, the wax inside is poured out through the small holes that were originally opened, and a mold that can be used for pouring is made.

By the end of the evening, the tin and copper in the furnace had melted and fused together.

When the valve is opened, bronze water flows into the crucible.

Wang Lung 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 that had been opened in a fixed plaster ball.

Like 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 personally sealed the power of those flames in the stone balls one by one.

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

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

Wang Lung shook his hand, it wasn't that he was tired, the main thing was that he was too nervous during this time, for fear that the copper water containing high temperature would spill out a little.

Wang Hao didn't know that the lost wax method was actually a very luxurious method. Because a mold, after being used once, cannot be used again.

The reason why he chose this method is mainly because of his friend's small workshop, where the hilt of the sword is made of relatively fine items, and some fine things are often carved according to the customer's requirements, so he will use this method.

In fact, in ancient times, casting these rough agricultural tools did not require any fine operation, and most of the workshops used stone models that could be used repeatedly.

By dinner, the balls were still glowing with a staggering heat.

Wang Hao didn't use water to cool it, after all, in terms of casting, he just went to help people for a few days, and he was basically in the position of a little white.

He remembered that the friend had said that if the ratio of materials was not handled properly, the water cooling could cause the appliance to crack or even explode.

He didn't know what the exact ratio would be, so he had to wait until later and try it slowly.

Although the temperature has not dropped, the copper water in the plaster has solidified.

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

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

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

It can be said that the most important people in Wang Village now, or the group of people who control the most power, except for Wang Ba, who trained prisoners 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 the plaster balls contained all sorts of things that his people had carved out of tree wax.

There's hammers, there's axes, there's headshots, and so on.

Except for Wang Long, basically no one in the rest understood why Wang Hao brought them so cautiously to see these things, and even Gu Mu, who was supported over, didn't know what kind of official Wang Hao was selling.

Looking at the puzzled crowd and Wang Hu who was probing his brain, Wang Hao handed a small hammer to Wang Hu, and then said, "Huzi, you go and find a plaster ball at random, and then break it." ”

Wang Hu was confused, he was building a house in the afternoon, and he didn't participate in the casting, so he didn't understand what Wang Hao wanted to do.

However, for Wang Hao's words, he is unswerving.

Picking out one of the plaster balls casually, Wang Hu pinched his ears, and then said with a surprised face: "Ah! Hao, this is still a little hot! ”

(I have a fever and want to go to bed early, this chapter is only two thousand words.) (To be continued.) )
