Blacksmith Qin said: "The iron tools we have made during this time have been arranged by the horse steward to be sold, but they are in short supply!" ”

This is probably the case in ancient times, and there have always been two problems! One is that there is an extreme lack of supplies! It's nothing! Anything in the market can be used as money! On the other hand, there is a shortage of money! I mint money every year, but there is not enough money every year! At present, the horse steward is selling the iron tools of Ningfu along the canal along the rocks along the canal, which can be said to be in short supply!

Zhao Yan said: "Can we still expand the scale? How many are there now? ”

Qin Qiujiang shook his head and said, "There are nearly three hundred people now!" The steward has found a yard to settle again! If you expand it any further, it won't work! You always have to pay attention to learning to lead people, and now the masters have brought three apprentices! If you add apprentices, you won't be able to take care of it! ”

Zhao Yan nodded! said: "Can iron ore be supplied?" ”

Qin blacksmith said: "Iron ore is nothing, but charcoal is almost out of supply, and now the charcoal in Pingxian County is a long-term price!" The proprietor has to find a way! ”

Zhao Yan said: "Can you use coal? ”

Blacksmith Qin paused for a moment and said, "I haven't tried this!" I don't know if it's okay! I'll call an apprentice to buy some and use it! ”

"Do we already have one for sale in Pingxian?" Zhao Yan asked. Pen ~ fun ~ pavilion www.biquge.info

Blacksmith Qin smiled: "It's not! It's good to use it on fire! Now with charcoal, it is more convenient than firewood! It's just that the smoke is getting bigger! ”

Zhao Yan smiled, "If you want to use charcoal, you still have to make coke!" Otherwise, the heat will not be reached! ”

Blacksmith Qin hadn't heard of this word! A look of confusion!

Zhao Yan smiled: "Similar to charcoal, it is that the charcoal is also roasted on the fire, and it becomes coke!" ”

Only then did Blacksmith Qin understand, nodded, and said, "That's exactly the truth!" Presumably, the charcoal also needs to be refined! ”

Zhao Yan said: "You and I go to the charcoal kiln!" And then we coke ourselves! ”

There are several charcoal kilns in Pingxian County, and there is a fire underneath, and the kiln is filled with firewood, and after being closed with wet soil, it will be burned for several days and nights! When it gets cold, the firewood in the kiln will dry up and turn into charcoal! Can provide a higher heat!

When I arrived at the charcoal kiln, I found several masters who burned charcoal! Zhao Yan smiled at the master surnamed Yan and said, "I want to ask Mr. Yan to burn a few kilns of coke!" The price is easy to say! If we use it well, we will become regular customers in the future! ”

Old man Yan, seeing that it was Zhao Shusheng, said, "It's you, the descendant!" The matter of burning charcoal, I have never heard of it! I don't know what it is? ”

Zhao Yan said the matter of coal burning and coking again!

Old man Yan said: "It's easy to say! Scholar, bring the coal! Let's get started! "Old man Yan also heard the story of Zhao Shusheng, and he knows it clearly! Happy to help!

Zhao Yan asked someone to pull a few carts of charcoal over, and immediately sealed it, leaving only a small mouth on it to breathe!

This burn burned and burned for several days and nights! Zhao Yan felt that this efficiency was really a bit low! But there's a reason for that! Refractory bricks can be used in this, so the soil layer is isolated from the open flame, so the thermal efficiency is transmitted to the kiln for a long time! In a word, the design of this kiln is unscientific! It's better to use a large iron pot! But after a few days of burning, it's finally burned! Let Blacksmith Qin pull it back and use it right away! Blacksmith Qin said, "It's better than charcoal!" The main thing is that the calorific value is a little more uniform! It has been burning for a long time, too!! ”

Zhao Yan looked at this coke, but what he thought about in his heart was steel! smiled: "Can your small furnace burn this iron ore?" ”

Blacksmith Qin smiled and said, "Some don't need to be burned, good iron ore can be burned red!" But it's hard to find, and it's not easy to buy! ”

Zhao Yan knew what he meant! He said, "Let's build a furnace to make iron!" ”

Blacksmith Qin couldn't laugh anymore, "I want to build a big furnace!" But I don't! ”

Zhao Yan asked: "Do we have anyone here who can build a big iron furnace, as long as we can burn iron ore into molten iron!" ”

Blacksmith Qin thought for a moment and said, "I've never seen such a big battle, I don't know how to build it!" ”

Zhao Yan had no choice but to say: "You don't care about this, and go to Meixian with me!" There's charcoal there! Let's try to build a furnace there first! ”

Blacksmith Qin had no choice but to follow Zhao Yan to Meixian in a carriage, and Lu Yatou followed, this little girl has become Zhao Yan's full-time bodyguard!

Zhao Yan didn't dare to go to Huangfu at this time, he came directly to Lijiaji, got off the carriage, and saw that there were more people here, digging coal! Li Laosi's body was clean, and when he saw Zhao Yan coming, he trotted over and said with a smile: "Has the big shopkeeper come to check?" ”

Zhao Yan smiled: "That's not what it means!" The main thing is something else! I heard that our charcoal has been sold to Pingxian? ”

Li Laosi said excitedly: "It's not! Now not only Ping County, but also Mei County is also using it! There are a lot of people who use it! ”

Zhao Yan explained some safety things, and encouraged him again, so he let him continue to work!

Zhao Yan entered the pottery kiln next to him, which was already full of pottery and porcelain, and it seemed that this section had made a lot of progress!

The master pottery maker saw Zhao Yan and said with a smile: "Owner, our pottery is now cute and welcome!" And I made porcelain! Now many families in Meixian County come to buy our porcelain! "He is very proud, it can be regarded as his skills have been sublimated, and more importantly, he has a good apprentice!

Zhao Yan smiled: "I can see the credit of the master!" Thank you so much! Is Xiaohu still in the kiln? ”

The master pottery maker shouted, and called Qin Xiaohu out, after a period of exercise, he was already dark, strong, and his face was red!

Qin Xiaohu was very excited when he saw the teacher, and said with a smile: "Teacher, have you seen the porcelain I made?" It's more beautiful than jade! ”

Zhao Yan smiled: "I saw it!" I saw it when I was in Pingxian! You must have been known by many people by now! Especially with your name on the porcelain! You're famous! But keep up the good work! The teacher has one more thing he wants you to do! But it's a matter of refractory bricks! ”

Qin Xiaohu hadn't heard of this refractory brick! "Teacher, what are refractory bricks!? Can it pass through the burning bricks? ”

Zhao Yan nodded and said: "You have seen these pottery, some of them can be used as pots, which are equivalent to pots!" So the teacher wanted to make a brick that would not break after being burned by fire! Can you do it? ”

Qin Xiaohu asked, "What does the teacher want this brick for?" ”

Zhao Yan said: "If you want to build a big iron furnace to burn iron ore into molten iron, you can't use ordinary bricks!" They're going to be burned to pieces! ”

Qin Xiaohu heard about the iron smelting and asked, "Does the teacher need a lot of iron?" ”

Zhao Yan smiled: "Yes! A lot! The teacher wants to use iron to build a house and pave roads! I still want to build a ship! Finally, it's a weapon! Strong our Datang! That's what the teacher wants to do! Would you like to help the teacher? ”
