Don't mess with that dragon

Chapter 149 Copper Alloys

Pure copper is actually not suitable for making weapons. In human history, bronze was the first to be used on a large scale.

Bronze is an alloy of copper.

When Austin was studying chemistry in high school in his previous life, he might have explained the chemical composition of the bronze alloy in detail, but after so many years, Austin has already forgotten most of this knowledge.

Although I have forgotten most of it, it doesn't matter, because when I was reading and saw the introduction of ancient people refining bronze, I was very curious about how those ancient people added those active metals to copper, and how they refined these active metals. sex metal?

Austin, who had doubts at the time, went to check it out, because he knew more about those things. It turned out that when bronze was refined in ancient times, ancient humans often added some associated ores produced in copper ore to copper ore, and those associated ores Ore is what is needed to form a bronze alloy, and after adding those associated ores, the bronze alloy formed has a lower melting point than copper, which is more conducive to refining.

As for what elements those associated ores are, Austin has already forgotten all about them, and it is estimated that those ancient humans would not specialize in studying the composition of those associated ores. As long as they can refine usable bronze tools, who cares about you? What are the elements of this thing?

Now that he remembered that bronze refining needed associated ores, Austin naturally began to try, asking the kobolds present to find other associated ores in the copper mine.

Since the refining of copper mines started, Austin also discovered that the kobolds seem to have a good talent in mining and prospecting. Perhaps in the future, when they want to find other ores, they can set up a prospecting team composed of kobolds. team?
With a talent for prospecting, the kobolds quickly found out the associated ore that was different from the copper mine, and sent it to the blast furnace.

In this nearly a month, the dragon nest orcs not only developed a specific method for refining copper, but also produced a lot of copper raw materials according to Austin's orders. Since they have copper raw materials, Austin does not intend to trouble , directly put the refined copper into the fire, then add the associated ore, and put it directly into the earth blast furnace for re-smelting.

With the efforts of all the orcs, it took a long time to create a khaki axe.

"Not cyan? Are these problems with the metal element composition of the associated minerals?"

Looking at the newly baked axe, Austin was full of doubts.

Although it is not bronze, judging from the situation during refining, the melting point has indeed become significantly lower, so there should be nothing wrong with it.

"Take it and try it."

Although it was not the bronze as imagined, Austin still let an orc take it for a try.

So a strong kobold took an ax to a nearby tree and chopped it up. To Austin's surprise, this ax was sharper than the stone axe, and it was also harder. A big tree was chopped off, but judging from the sharp edge on the axe, there was no wear and tear.

"Your Highness, Your Highness. We have succeeded!"

Gulu, the goblin who was in charge of smelting copper, looked at the ax fanatically, and was so excited that he could hardly speak. He spent more than a month burying his head in this copper ore stronghold to fight hard. Thought it was a failure.

But now, from this axe, all of them saw the hope of success.

Austin didn't speak. He finished the ax and weighed it in his hand. His claws bounced lightly on the surface. It felt similar to the iron axes paid by the Dragon Nest tribe.

Although it is not the bronze as imagined, its properties are similar to iron, and in this humid world, copper has better properties than iron, at least it does not need to spend a lot of effort to prevent rust.

In fact, in the vicinity of the entire Dragon Nest tribe, all the surrounding tribes use weapons such as wooden spears, stone hammers and axes. Austin has only seen iron weapons a few times. It can be said that within a radius of a hundred miles, almost all the ironware paid by the Claw tribe branch and the weapons in the hands of the mercenaries are in the Dragon Nest tribe in Austin.

The orc tribes living in the entire Kava Forest are basically primitive civilizations of the Stone Age, and there is no basis for smelting metals at all.

"First refine ten great swords according to the amount put in before, and don't relax about the rest. It's best to keep experimenting with the refining of these coppers."

Since the properties of these copper alloys are not inferior to ordinary iron, let’s cast ten large swords for the training of the orcs in the Lanjiao test group. However, in Austin’s memory, the best copper alloy weapons are still bronze, so it is required to The orcs continued to experiment.

Over time, the Dragon Nest orcs who stayed around Austin were also influenced by some of Austin's modern thinking. The cultivation of non-toxic mushrooms in the mushroom house in the Dragon Nest tribe, the innovative manufacturing of the manufacturing workshop, the establishment of the witch doctor treatment system, Even the formation of the iron block combat skills is largely the result of variable experiments, inductive analysis and other thinking that Austin instilled in the dragon nest orcs.

Constantly experimenting by changing variables, combining the results, and obtaining the optimal method is the result of the continuous diffusion and development of Austin's modern thinking in the Dragon Nest tribe. Although these intangible things seem inconspicuous, the Dragon Nest The establishment of each tribe system is based on this kind of thinking.

And with this kind of thinking foundation, Austin does not need to teach by hand, as long as the task of improving the copper alloy is issued, the orcs will naturally carry out continuous experimental improvements.

"It would be best to be able to produce bronze. For the time being, bronze weapons are the most suitable weapons for the tribe, and bronze has developed to a certain extent, and it is not inferior to some steel."

Looking at the ax in his hand, Austin thought silently in his heart.

But what Austin didn’t know was that the bronze was not actually blue in the first place, but the newly baked bronze was an earthy yellow like gold. It is only a layer of cyan patina, so it is called bronze.

So he wanted to refine cyan copper from the clay blast furnace, which was basically impossible.

After several days of delay in the copper ore stronghold, Austin finally forged ten great swords with the collective efforts of hundreds of orcs, and successfully unsealed them all.

Later, while Austin gave the orcs research on better copper alloy orders, he also asked them to manufacture some copper alloy armor and some production tools with the previous technology.

After issuing the order, Austin returned to the Dragon Nest tribe with the ten great swords.
