On the first day, Klavason forged the iron weight ten times. The sheer repetition made him feel very bored. On the second day, this boredom and boredom will continue.
Hanukkah is coming soon, what new tricks will this year’s festival bring?
If a dagger can be made before the festival that satisfies the financial owner Rurik, the leader Otto will surely be satisfied as well.
The next day, Rurik was still spending time in the blacksmith shop. He was supervising the work of the blacksmith and chatting about daily life in order to eliminate boredom.
If there was anything new for the two blacksmiths, it was using the soap they bought for two silver coins after finishing a day's work.
My hands were full of slag and toner, and there were ashes between my fingernails. As well as his huge beard and hair that have been swollen by the heat of the flames, Klavasen has always felt that the work of a blacksmith can turn a person into a big lump of bacon, which will always exude the smell of charcoal.
The use of soap changed everything.
The blacksmith shoveled snow into a pottery jar from outside at will. The jar was roasted on the fire, and they washed themselves with clean hot water.
The wooden door is closed, and the pottery urn is full of hot water. If you want more hot water, it is easy to get it.
"Today's work is really tiring. Fortunately, your soap can save us." Klavason took off his linen lining while looking away. At the same time, young Kawei also Doing this kind of thing.
Rurik immediately understood that they were not simply washing their hands and hair, but taking a shower.
Their performance did not make Rurik feel strange at all, and their subsequent performance made him feel even more amazing.
Klavasen used iron tongs to cover the stove lid made of an iron plate, and when it was hot, he poured water on it. The cold water immediately turned into a large amount of steam. After a while, the dry blacksmith shop turned into a sealed steam bath.
The entire room was enveloped in hot and humid mist.
Rurik could barely see that the two guys were wiping their bodies with wet linen cloth. Kawei was also self-taught, holding soap and rubbing it hard on his skin.
In the absence of a shower, this method of boiling water and wiping the body is probably the cheapest way to clean. Even though they have to make the house damp by the way, they have to go to a sauna.
But this is not a sauna, it is just a way for Klavasen to try to make the materials warmer. Don't worry about the steam getting the dry clothes wet. When the wooden door and closed chimney are opened after the bath, the room will soon be dry again.
They all cleaned themselves up, and Rurik did the same.
In different time and space, wipe your whole body with soap and then rinse it off with hot water.
"Ah! At least this will give you a sense of modern life..."
Or maybe after taking a bath, Rurik slept deeply that night.
Life is generally quiet and slow. On cold nights, those who intend to go elsewhereThe guys who plundered and enriched their cash boxes had to stop.
The adults stay in their warm homes and wait boredly for the ice and snow to melt, while the children spend almost all their childhood in boredom.
The feeling of boredom has always been with Rurik, and he felt that he had to do something. I used to be too young, and I couldn't do anything at the age of five or six.
According to tradition, you can claim to be eight years old in the new spring, and this Nordic body is obviously growing faster. As height and strength enter a period of rapid growth, people's subjective initiative also needs to be improved.
Teaching blacksmiths advanced iron-smelting techniques compared to their peers in this time and space is a useful start. After that, I will definitely make greater achievements in the research and development and production of weapons.
So, can a dagger with a medium carbon steel blade and a high carbon steel blade be successful? It depends on the in-depth processing in the next few days.
After a relaxing bath, the soap took away the mud and smoky smell from the two blacksmiths, and seemed to take away their fatigue.
On a new day, Klavasen and Kawei started to repeat the work of the previous two days with 100% energy.
Repeat ten times every day, and each cycle has been calcined to a critical point.
In fact, when iron bars are wrapped in plant ash and carbon powder and calcined, the penetration efficiency of carbon molecules is still poor. Compared with the carburizing method for manufacturing alloy steel, it is not as efficient as the loss of carbon method. That is the extreme temperature at which the blast furnace burns charcoal, produces a large amount of liquid pig iron, and then uses some methods to decarbonize the pig iron. Only this method can produce carbon steel more efficiently, and there is no need for "fifty refining" or "hundred refining" "The exhausting blacksmith's craftsmanship.
As long as the money is enough, Klavasen and Kawei will no longer complain.
Blacksmiths, their identities in any tribe are complicated.
The blacksmith did not believe in Odin, so he was naturally sent out of the battle by the warriors of the tribe. However, all production activities of the tribe require blacksmiths to make tools for them. The tribe, especially the warriors, especially need them.
Due to the characteristics of traditional block iron smelting, it is most suitable to be made into an axe. One edge of the ax is the sharp weapon, and the other side is the hammer head. The ax blade is the key to felling wood, and the hammer head can smash the enemy's armor. The battle ax is a suitable weapon, but it is too bulky.
Generally, unless a warrior's ax blade breaks, they will find a local blacksmith to help repair it.
The so-called practice of kindness is not much different from what Klavason is doing now.
But to others, the work of repairing good things seems to be that the blacksmith burns the damaged goods red and knocks them back to their original state. It seems that as long as the fire is mastered, any strong person can easily complete it. Just for good deeds, Klavasen's customers would not pay much, often only a few dozen copper coins.
Usually, he can only earn one silver coin after completing the repair of three axes, and the charcoal consumption during the repair process must also be considered.
Repair Tomahawk, that was beating against a huge piece of iron. Compared to the iron bar that was only one third of the length of the stika that Rurik requested, any beating was not very troublesome.
If they were all tools for repairing this size, Klavason calculated that it would take six repairs to earn one silver coin. Thinking about it this way, the silver coins given by Rurik were indeed more.
This was the case on the third day, and it was also the case on the fourth day. On the fifth day, it was getting closer and closer to Rurik’s requirement of repeated calcining and forging fifty times. Klavasen’s mood He also became more and more excited.
As a professional blacksmith family in the tribe, the family is very underdeveloped. He attributed this to fate.
However, his son inherited the blacksmith's career very well. After working for a long time, the two of them still figured out some skills from the boring work.
Although they did not spontaneously invent some new technologies to make iron smelting more efficient.
They have good skills in smelting bronze, and can cast strange-looking bronzes in clay mold casting, such as those sold or given to the priests' longhouses.
For example, when bronzes are smelted, the tin and lead content determines the color of the bronzes. The two of them already knew how to adjust the weight of raw materials to make the most suitable alloy solution, and they had already made gleaming bronze.
But in terms of iron smelting, the iron weights made by the two men were all black, which seemed to be the case with iron.
After making axes and swords, they need to be polished. It can reflect the luster of beautiful metals. For example, iron swords are a very nice silver-gray color, but they are not resistant to cutting at all. For example, After cracking the stone several times, the blade curled.
Clavason always knew it in his mind. He counted the number of times the iron bars were calcined and forged.
His forehead was covered with sweat, and he asked excitedly: "Rurik, this is the forty-ninth time, and our mission is about to end."
"It's almost completed. !" Rurik stood up suddenly and patted the dust on his leather jacket. "Continue to do it after fifty times."
"Okay, mine. Child. There are some strange changes in this iron bar."
"Oh? What is that?" "It has changed color in the past few days." He could no longer hide his doubts, because in decades, he had never seen the ironware he made. In addition to turning red all over due to rust, the ironware also had other color changes. "I think the color of this iron bar became brighter after it cooled down."
The description of the color immediately caught Rurik's nerves.
Rurik hurried to the hot stove: "Really? Let it cool naturally and let me see the color change."
The folded and forged iron weight turned back into The iron bars were removed, and the open wooden door allowed the cold air from outside to pour in. The room became cold, but it was still hot next to the stove.
Cold windUnder the influence of forty-nine tempers, the color of the iron bar really changed!
Klavasen held it in his hand after it was completely cooled. As long as it was compared with the iron tongs made of wrought iron, the color difference between the two could be clearly seen.
It is as if sunlight is shining on the forty-nine iron bars. Its color is obviously brighter, and it seems that a little white dye has been added to make the iron bars whiter.
Is it really spiked? certainly! That’s carbon!
Rurik was as happy as if he had eaten honey. He stamped his feet and screamed desperately. The joyful celebration scene did not mean that the five days of hard work of the blacksmiths were not in vain.
"Have we succeeded now?" Klavason held down the excited Rurik.
"Yes! It was basically successful. I did it for the last time, smeared grease with ash and carbon powder, and calcined it for the last time. Then it cooled naturally and made it look like a sword."
< p>Finally it was time to make the sword embryo, and Klavasen took it for granted that this was Rurik's last request.It seems that as long as he works harder tonight, the sword Rurik wants will reach the final stage of sharpening.
The last calcination was completed in the blacksmith's eager anticipation. The bucket of water finally leaked completely. Clavarson couldn't wait to use the tongs to take out the red iron bar. Can we still call it an iron bar now? No, at least it’s a low carbon steel bar!
Clavason did not forge the two pieces again, but worked together with his son Kawei to strike while the iron was hot.
The two are really good at shaping iron bars into the shape of a dagger, and according to past habits and traditions, the shape of the sword is different from what Rurik thought.
Swords made of wrought iron are not suitable for chopping. Indeed, the invention of the sword was to lengthen the spearhead as much as possible. From the beginning, the killing method of the sword was mainly stabbing.
The wrought iron sword inherited this tradition, which made the Clavarsons, on the one hand, hammer the sword into a shape with a middle spine, and it also has a terrifying sharp edge, seeking the best at once Stab effect.
In the past, iron swords were made in this way. Klavasen follows this method. Is it also suitable for the processing of steel swords?
The shape of the dagger satisfied Rurik. Look at the sharp edge of the sword. Even without an edge, it is still very dangerous.
After a lot of hard knocking, coupled with countless fine chisels, the dagger became more and more beautiful.
"As long as it is quenched for the last time, it should be done. As long as we sharpen it, we can try to see if it can cut off iron blocks." Klavasen said, and asked his son Kawei Go and turn the whetstone inside out.
Rurik immediately stopped Kawei and ordered: "There is still very critical work that has not been done!"
"Huh? There is more?" Karavasin asked.
"The sword will stay like this for now. Blacksmith, you go make some more mud."
"Okay...Okay."
Clavason didn't know what the child wanted mud for. He never lacked clay and mud here, because all the stoves in his house actually needed a long time to repair. Those iron smelting slags are actually some disaster substances. Once they accumulate too much, they will destroy the bottom layer of the furnace. Therefore, the stove needs to be repaired every once in a while, and the repair material is clay.
Some mud has been made. In fact, it cannot be called mud. It is more appropriate to call it a mud block.
Here, Rurik personally kneaded the mud into strips as if kneading dough, and attached the mud strips to the back of the sword with backbones on both sides. After flattening, there was only a ready place for cutting. Exposed.
"Rurik, you...what are you going to do?" Klavasen asked with a puzzled look.
"Of course, cover it with soil and calcine the blade. Believe me, doing this will make the blade the hardest thing in the world." Rurik said this deliberately, but it seems that humans in this era also No practical tool can be made harder than high carbon steel.
He continued: "You can grease the blade of the sword, stick it with plant ash and charcoal, and continue to burn it over fire. But this time we will burn it for a long time."
"Approximately how long?"
"This..." Rurik didn't know what to think, so he took it for granted: "Five buckets of water. When all five buckets of water are drained, we will Take the sword out again and we will quench it directly."
How long does it take for a bucket of water to flow out of the small hole? Rurik feels that it is not a short time.
In fact, it will take at least ten minutes to flow out. The "five buckets of water time" mentioned by Rurik slapping his thigh is already barely more than an hour.
Karavarson didn’t waste any time. He put the sword into the charcoal pile again and began to cover it with soil and burn the blade.
Until now, Rurik still has not told the blacksmith the series of incredible processing methods he requested and the principles behind them.
Even now Klavasen has been asking, does the calcined iron sword also need to be fired with a piece of ceramic?
Indeed, with more time, any shape of clay can be fired into pottery pieces. The processing method of pottery is very simple. As long as there is enough clay, mass production of pottery becomes possible.
The "five buckets of water time" finally passed amidst people's anxiety, and Klavason couldn't wait to take out the sword with two pottery pieces attached.
The Tao's attachment peeled off the moment he left the fire. Klavason looked at the sword embryo held by the tongs with experience and thought deeply.
Rurik hurriedly urged: "Quench quickly! Use snow water directly this time! Quick."
No oil quenching was used, this time it was directly quenched with water, and he was burned. The temperature of the 600-degree iron bar dropped sharply, to the point where it could be touched by human hands in just a few seconds.
Now, Klavason found that the sword embryo in his hand had become incredible. Because its whole body is still bright white, and there are many small unevennesses on it that need to be polished., but it cannot cover up its unique color at all.
The most amazing thing is the area where the edge is prepared. These areas are the brightest and whitest, as if they are not the same material as the back.
Unlike Klavasen and Kawei, Rurik is only happy here.
"Haha! I succeeded!"
"Kid? We really succeeded?!"
"Of course. Blacksmith, thank you for doing this. . I am very happy that you can help me sharpen it as much as possible. I will pay you two more silver coins now." "Oh?" Karavarson? Very pleased with Rurik's further generosity.
"Of course! But I must tell you that this sword is completely different from the ones you made before. Its cutting is probably a more laborious process. But your hard work will have good results. ."
"You mean you can cut off the iron sword in my warehouse with a sharp blade?" Clava asked.
"Of course! I will always be with you. When my sword cuts off your ordinary iron swords, I will tell you how everything works. From then on, you can make swords."
p>
At this moment, Klavason felt that the blacksmithing skills he had learned from his dead father were too weak. If everything came true, he would have to kneel down and face "Odin's Blesser" Liuli. Gram, to thank him for the "advanced blacksmithing technology from Valhalla."
