~： Two hundred and six, Karazhan's people came in

Pottery does fail to fire. After all, these clays are not 100% qualified, and there are some impurities in them.

The first pottery that I took out showed cracks. This large-looking pottery was a defective product.

The second clay pot is perfect, without cracks.

The third, fourth, first...

a total of 12 pieces of pottery, 8 pieces were successful, this success rate is pretty good, and the refractory earthenware pot that Zhao Yunxiang admires most is the most perfect.

This refractory clay pot is made by an old man who takes urine and mud. It is 1 meter in height, half a meter in diameter, and 5 cm in wall thickness.

The old man’s craftsmanship is good, this refractory pot can be used to smelt bronze.

The earthenware pot was completely cooled, Xiaoqiang filled some water with the earthenware pot he made, and then held it to drink.

"This is really convenient for drinking water!!"

"Really, the boss is really amazing, the mud will become so hard after it burns, and the water can't be soaked at all."

Everyone in the tribe is passing and looking at pottery, this kind of water container is simply an artifact!

"Thank you guys!"

"Big guy is awesome!"

"I love you to death!"

Almost all the people of the tribe are grateful, and some even kneel down and begin to worship.

For a while, Zhao Yunxiang felt like he had become a god!

If more savages are recovered, then...it will no longer be troublesome to find Han Qianluo and others!

then~~~~ hey hey~~!

No longer YY, Zhao Yunxiang became more serious. After all, time is running out. Karazhan next door doesn't know when he will call. The production of bronzes is imminent.

"Now I will teach you how to smelt bronzes." Zhao Yunxiang said solemnly.

When I heard the bronze ware, everyone's ears stood up, and the legendary bronze ware was finally about to be made.

After Zhao Yunxiang was silent for three seconds, he was sadly discovered that he didn't even know how to make bronzes, there was no proportion! ! !

Yes, all qualified bronzes are proportional. Red copper, tin alloy, and lead alloy are fused together in a certain proportion, and finally become bronze with strong hardness and toughness.

What a pity, Zhao Yunxiang does not have lead, and the mixture of tin and red copper can only have hardness. This world is fair. God gives you hardness, which will greatly weaken your toughness.

For example, glass and diamonds, both of which are very hard, but fragile!

"Bronze...how do you make bronzes?" Xiaoqiang asked Zhao Yunxiang's serious and embarrassed expression.

"Actually... I only know how to do it briefly, and I have to experiment to know the specifics." Zhao Yunxiang is very real, I don't know or I don't know, how can I know the proportions of bronzes?

"Big guy, you take us to try it!" Xiaoqiang trusts Zhao Yunxiang very much. The big guy is awesome, even if the big guy has broken sleeves, I am willing! !

"Okay, let's experiment!" Zhao Yunxiang held the red copper scepter and the spear blade sharpened by the patriarch. "The purity of red copper is very high, because there are many impurities in this tin ore. We have to get rid of the tin ore first. Impurities inside."

Tin is a metal that often appears in our daily lives. It is similar to the motherboard of a computer. The solder on it is tin. The melting point of this metal is extremely low, only 230 degrees.

The patriarch’s spear blade was taken down violently. Zhao Yunxiang put it in a refractory clay pot and fired it with firewood. In just a few minutes, the temperature of the kiln reached more than 500 degrees. Obviously, the pottery The tin has completely melted.

Those that have not melted are impurities, these are some other ores and stones!

Pick up the residue, put the red copper scepter in, and continue firing. The melting point of the red copper is a little higher, about 700 degrees Celsius. According to the current situation, more firewood is needed to melt the red. copper.

"Now let's wait here quietly." Zhao Yunxiang thought for a while and asked, "Who among you can carve wood?"

"No..." Xiaoqiang thought for a while, "My uncle is best at making mud."

"Forget it, let me do it." Zhao Yunxiang looked at the kiln, where there were few red copper and tin ore, and he couldn't fully arm the entire tribe.

If you make a spear blade, you can only make a few at most, but if you make an arrow, you can make a hundred.

After weighing in, Zhao Yunxiang still plans to make arrows!

The bronzes made by the ancients were all made by casting method, which is to make a recessed model of clay, plaster, etc., and then pour copper water into it. After cooling, the bronzes are made.

Zhao Yunxiang found a piece of wood, which was grinded with a rough stone and sharpened with a stone spear blade, finally making it into the shape of an arrow.

Finally, I pressed the arrow into the mud to make a concave mold. At least a dozen molds were made.

Soon, the red copper in the kiln melted completely, and the copper water was mixed with the tin water. I don’t know if this ratio was correct. Zhao Yunxiang didn’t require much, and only hoped that the mixed bronze had hardness.

You should know that copper is rarely used as a weapon completely, mainly because it has no hardness.

The mixed copper water was scooped into the mold with a pottery spoon. Zhao Yunxiang was very careful when doing this process. Copper water was scarce and he didn't want to waste it.

Ten minutes later, more than 200 arrows were made out of a dozen catties of copper water. These arrows basically reached the standard, but they still need to be sharpened.

Time flies quickly. I have been making arrows and wooden bows for most of the day. UU reading waited until the sun went down and finally made a large number of arrows.

"This is a bow and arrow!" Zhao Yunxiang drew his arrow and drew his bow, aiming at a tree in the distance, which was 40 meters away from here.

The bowstring of the wooden bow is made of slender bark. There are many trees growing in the forest. Some unknown trees have unusually tough bark. This was obtained after many tests.

Aim, take a deep breath, and then shoot the arrow quickly!

"Wow~!"

"pecks~!"

The arrow shot out like a thunderbolt, and finally hit the trunk of a big tree with accuracy. It could be seen that Zhao Yunxiang pulled the bow very hard. When the arrow plunged into the trunk, the entire arrow shaft was trembling.

"Hiss~!"

The wild people have good eyesight. They clearly saw the arrow hitting the tree trunk, which shocked everyone.

Arrows appeared in the Neolithic Age 28,000 years ago. At that time, the arrows were made of flint. Zhao Yunxiang planned to let the tribe savages directly cross the Neolithic Age and directly from the bronzes of the Spring and Autumn Period and Warring States Period.

"Well, you should practice archery first, and remember not to shoot arrows at people." Zhao Yunxiang has been busy for a long time and is very tired, and is planning to go back to the thatched house for a nap.

People are tired, and they can fall asleep in any environment. I don’t know how long they slept, but Zhao Yunxiang was awakened by a loud noise.

"The Karazhan tribe has attacked and come in!!!"
