Chapter 67 Bronze is not cyan

After the shoulder recovered almost, Wang Lang asked people to build copper smelting furnaces according to their own ideas.

When other people were busy making mud, Wang Lang put the copper ore into the pottery kiln and calcined it with carbon fire. After a day of hard work, Wang Lang got a total of more than 30 catties of pure copper. Seeing these copper blocks, Wang Lang planned to The first step has been successful.

Wang Lang planned to make saws and nails out of these copper ingots with pits and pits of different sizes.

If you want to make a relatively regular mold, a flat board is very important. At present, no one in the tribe can make a very regular shape with bare hands.

In the next two or three days, Wang Lang asked others to smelt the copper ore, and he carefully carved the shapes of saws and nails on the clay board with small branches.

Since there was no ruler, Wang Lang repeated many times to make some molds that could still be seen.

After drying the mold, Wang Lang carefully moved it to the side of the copper stove.

Since there is still some tin in the tribe, Wang Lang plans to make bronze directly, skipping the Bronze Age and striding forward to the Bronze Age.

The preparatory work has been completed, and whether the world's first bronze ware can be produced depends on the next situation.

Copper smelting has reached the most critical step. After several baskets of charcoal were brought over, everyone gathered around the copper furnace, waiting to witness the birth of the first bronze ware.

Wang Lang didn't know what was the best ratio of copper to tin for bronze ware. Since the current reserve of tin in the tribe was relatively small, when Wang Lang added materials to the furnace, the amount of copper should be more.

As the wood in the firepit is lit and the roof is closed, people cannot see what is going on inside the stove.

Wang Lang held the wide leaves of the palm and kept fanning the firepit. As the temperature of the stove continued to rise, the onlookers had to step back a few steps due to the scorching heat.

Since there is no blower equipment, relying on manpower to supply air to the firepit is a very physical test. It didn't take long before Wang Lang was already sweating profusely. It is absolutely impossible to do such a thing in this hot weather. A very tormenting thing.

Wang Lang was so tired that he couldn't fan the fan anymore, so he asked others to replace him and continue to fan the fan. In order to prevent people from heat stroke, Wang Lang asked the women to prepare a large amount of salt water to supplement water and salt for those who were exhausted physically.

After waiting for more than an hour, a red liquid slowly flowed out of the groove on the furnace wall. Seeing this, Wang Lang hurriedly put the pre-fired clay pot under the groove.

The viscous copper juice looked like lava, exuding terrible heat. When the copper juice stopped flowing from the copper furnace, Wang Lang ordered the copper furnace to be extinguished, and put several layers of animal skins on the clay pot, holding the pot, Slowly pour the copper juice into the prepared mold.

After filling the grooves of the saw mold, there was still a lot of copper liquid in the clay pot, so Wang Lang poured the rest into the nail mold.

Although the previous steps are complicated, at this point, people already know what to do next, and people have experience in smelting tin before.

Just pour the melted liquid into the mold, and the rest is to wait, take it out after the melt has cooled, and the rest is to polish.

But people don't know what these strange molds made by Wang Lang are for, so they can only hold back their curiosity and wait for the moment when the answer will be revealed.

As the molten copper slowly cools and solidifies, the tools in the mold gradually take shape. The light golden copperware in the mold attracts everyone's attention. It shines brightly under the sunlight, which is really beautiful.

The original color of bronze is yellow, and the reason why the bronzes unearthed in later generations are blue is only because of the long-term oxidation that covered the surface of the copper with a layer of verdigris.

Wang Lang looked at the blinding saw and almost regarded it as gold.

"Which scum directors in TV dramas mislead the masses, they say that something black is bronze, and the bronze with tin added in front of them is yellower than gold." Wang Lang despised those shoddy TV dramas in his heart.

After the bronze ware cooled for a while, Wang Lang used the water-soaked animal skin to put the mold into the earth pit filled with water.

The copper that seemed to have cooled was actually extremely hot. The moment it was put into the water, the water in the pit almost boiled instantly. After doing this, Wang Lang laughed happily: "The Bronze Age has finally come."

At night, Wang Lang couldn't wait to take out the cooled copper vessel from the pit. After removing the clay mold, a pale golden bronze vessel appeared in front of Wang Lang. , but it seems that using is not a problem.

People looked at this strange thing and asked curiously: "Lang, what is this?"

Wang Lang smiled and said, "This is called a saw, and it's used to cut wood."

"Can't an ax cut wood? What's the use of this thing?" People asked suspiciously.

Wang Lang smiled without saying a word, and asked someone to fetch a piece of wood, and said, "You guys have a good look."

The performance of the bronze saw soon shocked others. Looking at the flat cross-section of the wood, people could hardly believe their eyes.

Normally, it would take a long time for people to cut down a small tree as thick as an arm, but it can be sawed off in the blink of an eye with this tool.

"Lang, this thing is amazing." Huo said, staring at the copper saw in Wang Lang's hand.

Although this copper saw is a fetish in the eyes of others, Wang Lang looked at the cracks on the saw teeth and shook his head helplessly. The bronze is hard, but too brittle.

Wang Lang knew that this might be caused by the ratio of copper to tin, but he didn't know the best ratio, so he could only experiment a little bit.

Although this first bronze is not perfect, it is still an exciting thing.

Looking at the excited Huo, Wang Lang shook the saw in his hand and said, "How about it, now you know how powerful this thing is!"

Huo hurriedly nodded and said, "Excellent, it looks much more useful than an axe. With this thing, we can cut down all the trees we see!"

Hearing this, Wang Lang couldn't help being stunned. He cut down all the trees. What a joke, just with this broken saw in his hand, everyone couldn't do it to death. Moreover, this idea was very unfriendly, even though Wang Lang himself had He has a criminal record of arson, but he still despises the evil thoughts of forest fires.

"If you want to cut down all the trees, you can't do it with this saw. This saw is just a failure. It needs to be melted down and redone!"

"Why redo it? It's already very powerful!" People asked in confusion.

Wang Lang didn't speak, but took a stone and threw it at the copper saw.

There was a crisp sound of "pop", and the copper saw snapped.

The people who watched this scene were heartbroken. Such a good thing can be smashed.

Wang Lang held the copper saw that had been broken in two and said, "This thing is still too brittle, we have to try a few more times until we can make something usable."
