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

The first piece of pottery was cracked, and the large-looking clay pot was a defective product.

The second clay pot was perfect and there were no cracks.

Third, fourth, ......

Of the 12 pieces of pottery, 8 were successful, and the success rate was okay, among which the refractory clay pot that Zhao Yunxiang admired the most was the most perfect.

This refractory clay pot was made by an old man with urine and mud, with a height of 1 meter, a diameter of half a meter, and a wall thickness of 5 centimeters.

The old man's craftsmanship is good, and this fire-resistant clay pot can be used to smelt bronze.

The clay pot was completely cooled, and Xiao Qiang filled the clay pot he made with some water, and then picked it up to drink.

"It's so convenient to use for drinking water!!"

"Really, the big guy is really powerful, after the mud burns, it becomes so hard, and the water can't be soaked at all. ”

Everyone in the tribe is passing on the pottery, this kind of water storage container is simply an artifact!

"Thanks to the big guy!"

"Big guy is awesome!"

"I love you to death!"

Almost all of the clansmen were grateful, and some even knelt down and began to worship.

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

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

When the time comes~~~~heyhehe~~!

No longer YY, Zhao Yunxiang became serious, after all, time is pressing now, and Karazhan next door doesn't know when he will call, and the production of bronzes is imminent.

"Now I'm going to teach you how to smelt bronze. Zhao Yunxiang said solemnly.

As soon as they heard about the bronzes, everyone's ears pricked up, and the legendary bronzes were finally about to be made.

After Zhao Yunxiang was silent for three seconds, he was sadly surprised to find that he didn't know how to make bronzes at all, and there was no proportion!!

Yes, qualified bronzes are all proportional, red copper, tin alloy, lead alloy, and three kinds are fused together according to a certain proportion, and finally become bronze with strong hardness and toughness.

It's a pity, Zhao Yunxiang doesn't have lead, the mixture of tin and red copper can only have hardness, this world is fair, God has given you hardness, it will greatly weaken your toughness.

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

"Big guy...... How do you make bronzes?" Xiao Qiang saw Zhao Yunxiang's serious and embarrassed face, so he asked out loud.

"Actually...... I only know the rough way, and I'll have to experiment to find out. "Zhao Yunxiang is very real, I don't know if I don't know, how can I know the proportion of bronzes?

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

"Okay, then let's experiment!" Zhao Yunxiang took the red copper scepter and the spear blade sharpened by the patriarch's blade, "The purity of red copper is very high, that is, this tin ore contains many impurities, we must first remove the impurities in the tin ore." ”113

Tin is a metal that often appears in our daily life, just like the motherboard of a computer, which is used for soldering, and the melting point of this metal is very low, only 230 degrees.

The patriarch's spear blade was violently removed, Zhao Yunxiang put it into a fire-resistant clay pot, and then added firewood to fire, in just a few minutes, the temperature of the kiln reached more than 500 degrees, and it was obvious that the tin in the clay pot had completely melted.

The ones that don't melt are impurities, just some other ore and stones!

Pick up the residue, put the red copper scepter in it, and then continue to fire, the melting point of red copper is a little higher, about 700 degrees, in the current situation, it takes more firewood to melt the red copper.

"Now let's wait here quietly. Zhao Yunxiang thought for a moment and asked, "Which of you can carve wood?"

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

"Forget it, I'll do it. Zhao Yunxiang looked at the kiln, there was a pitiful lack of red copper and tin ore, and he couldn't fully arm the entire tribe at all.

If you make a spear blade, you can only make a maximum of 10 pieces, but if you make an arrow, you can make about 100 arrows.

Under the trade-off, Zhao Yunxiang still plans to be an arrow!

The ancients made bronze ware by casting method, that is, using clay gypsum and the like to make a concave model, and then pouring copper water into it, and after cooling, it was bronze.

Zhao Yunxiang found a piece of wood, which was sharpened with a rough stone and sharpened with a stone spear blade, and finally made it look like an arrowhead.

Finally, the arrows were pressed into the mud to make a hollow mold, and there were at least a dozen molds.

Soon, the red copper in the kiln was completely melted, and the copper water was mixed with the tin water, I don't know if this ratio was correct, Zhao Yunxiang's requirements were not high, he just hoped that the mixed bronze would have hardness.

You know, copper is rarely used completely for weapons, mainly because it has no hardness.

The mixed copper water is scooped into the mold with a ceramic spoon, Zhao Yunxiang is very careful when doing this process, copper water is scarce, and he doesn't want to waste it.

After more than ten minutes, more than 200 arrows were made from more than a dozen catties of copper water, which basically reached the standard, but they still needed to be sharpened.

Time flies, and I spent most of the day making arrows and wooden bows, and when the sun sets, I finally make a large number of arrows.

"This is the bow and arrow!" Zhao Yunxiang pulled his bow and aimed at a tree in the distance, which was more than 40 meters away.

The bowstring of the wooden bow is made of thin bark, and many trees grow in the forest, some of which are unknown and whose bark is unusually tough, which is obtained after many tests.

Aim, take a deep breath, and shoot your arrows fast!

"Whoosh~!"

"Peck ~!"

The arrow shot out quickly like a thunderbolt, and finally hit the trunk of a big tree accurately, and it could be seen that Zhao Yunxiang pulled the bow very hard, and when the arrow pierced into the trunk, the entire arrow shaft was trembling.

"Hiss~!"

The wildlings had good eyesight and could clearly see the arrows hitting the trunks of the trees, which shocked everyone.

Arrows appeared in the Neolithic Age, 28,000 years ago, when arrowheads were made of flint, and Zhao Yunxiang intended to let the tribal savages directly cross the Neolithic Age, directly from the bronzes of the Spring and Autumn Period and the Warring States Period.

"Alright, you can practice archery now, and remember not to shoot arrows at people. Zhao Yunxiang was very tired after a long day of work, and was about to go back to the thatched house to take a nap.

People are tired, they can sleep in any environment, I don't know how long I slept, Zhao Yunxiang was woken up by a noisy sound.

"The people of the Karazan tribe have attacked!!"
