Zhang Shao's shopkeeper understood the taste of being a star for the first time.

was proud, and suddenly saw a young man from the Zhan family's goods store, and hurriedly found it.

"Less shopkeeper, come soon!"

"Why are you in such a hurry?"

"The government is invited!" The young man pulled Zhang Yingquan and said as he walked back: "It's the official family who came from Qiantang with the county government, and said that he was looking for you to help make iron fan, what is iron fan?" ”

Zhang Zhiquan heard it, is this a business?

Since Xianfeng was in the dynasty, the new copper coins became a top priority, after the emperors of all dynasties ascended the throne, they all issued their own "Tongbao" and "ingots" and other coins, Xianfeng is no exception, so "Xianfeng Heavy Treasure" came out.

"Xianfeng Heavy Treasure" is slightly different from the coins of the past dynasties, just listen to the word "Heavy Treasure", maverick, all because of the implementation of the new construction method of "Iron Fan Copper" by the Ministry of Internal Affairs, that is, the use of Iron Fan "mold" to cast copper coins, a change from the previous mud fan coinage, the coins created are more full and bright.

In fact, this kind of construction method existed in the Ming Dynasty, and was used for coin minting for the first time in the Qing Dynasty, but the Qing Dynasty disdained KitKat, and the skills did not grow.

I didn't think about it, Fujian and Zhejiang casting yamen made a fool of themselves as soon as they opened the furnace, and it was not as delicate as the previous mud fan, and was reprimanded as "shoddy", and Fujian and Zhejiang casting made the old face unbearable.

Bai Xianglong, Manchu, Manchu surname Ye Hena, love Han culture, a lifetime of elegance, Daoguang raised people, is a five-grade civil official, this is really rare in the Manchurians, released to the south of the Yangtze River, Fujian and Zhejiang casting envoys also have two years, in charge of the two provinces of silver ingots and copper coins casting, issuance, power is not big, but a five-grade courtesy, oil and water will be big, but on the fire consumption of a fat to greasy, fat shortage in the lack of fat.

He hasn't had time to do anything in the iron fan copper, and the truth is true, and there is a problem? It must be that the construction method and skills are not good, and this iron fan is also rotten, so I am worried! At the end of this year, I have to be recruited, and I have only enjoyed this good life for two years, which is too humiliating!

So I asked around if there were any famous foundry craftsmen, and I heard that the blacksmith line was the "three knives" Zhang family in Jinxian County, and hurriedly came to Jinxian County, making chickens and dogs jump, and the five-grade official was not small, so he came to find the little blacksmith, and the county master was dumbfounded.

As soon as he arrived at the gate of the county office, the chief shopkeeper of the Zhan family hurriedly greeted him and said, "Casting makes the adults call." ”

Bai Xianglong is of medium stature, wearing a crystal top on his head, and is walking in front of the hall, and a servant hurriedly stepped forward and whispered: "Zhang Shao's shopkeeper has arrived!" ”

"Are you the young shopkeeper of the Zhang family's craftsman's shop?"

"Returning to adults, yes."

"Don't be restrained, this official doesn't pay attention to clichés. Q: Do you know how to make iron? ”

"Yes! But what's the use? ”

"Iron fan copper, cast 'Xianfeng heavy treasure'."

"Will system! But the craftsman shop is small, and many materials are not available. Zhang Yingquan's answer was straightforward, as if implying that he could just take something, but he couldn't do it in vain.

"The material is fine!" Lord Bai's eyes widened: "What else do you want?" ”

"Can you show me the sample money?"

The sample money seems to be also made of iron fan, which seems to be the craftsmanship of the Ministry of Industry in Beijing, which belongs to the second copy.

"How many days will it take?"

"Three days!"

"Good! Three days later, in the backyard, the furnace was opened to try the model. ”

Zhang Yingquan returned to the mountain town with the materials of the three donkey carts, and began to be busy as soon as he entered the door.

He used the lost wax method, first used gypsum to stretch the front and back of the sample money separately to make a gypsum model, and then poured paraffin wax after trimming to form a paraffin model, and further refined the edge strips and handwriting on the paraffin.

In this era, there is no refractory adhesive, and there is no chemical raw materials such as ammonia, so you can only grind the quartz sand to the fineness of the material, and then add clay to make mud, and carefully wrap the wax model with mud, especially where there are concave and convex words, to ensure that all are dense, and then leave a gate to make a mud fan.

After the mud fan is dried, it is turned upside down and baked over low heat, and the paraffin wax melts and runs out, and then the molten steel is poured into the mud fan, and after it is cooled, the mud fan is broken to make a steel fan.

It's easy to say, but it took two days to make, trial casting, and finishing it again after refinement.

On the third day, Zhang Yingquan hurried for a long time and came to the county office, where a blacksmith furnace had been erected, and Lord Bai sat on a chair not far away, watching the few craftsmen he brought busy before and after.

Zhang Yingquan instructed a leading craftsman to clarify the precautions, opening and closing requirements, etc.

After a while, the glittering bronze "Xianfeng Heavy Treasure" flashed into view, even more delicate and full than the pattern coins of the Ministry of Industry, and the glyph and frame were perfect.

Mold repair is also a science, this bowl of rice Zhang Yingquan has eaten for five years in later generations, can it not work?

Lord Bai didn't close his mouth since he saw the glittering "heavy treasure", just by virtue of this iron and bronze political achievements, there is hope for another journey in the official career, at least the current position is stable. He personally sent Zhang Yingquan out of the government and told him to wait in the city, there was a reward!

The next day, Lord Bai and the county magistrate appeared together, beating gongs and drums, lively and lively, and the official came to the Zhan family goods store with a plaque, and the reward was not much, fifty taels of silver, a lot! It is rare for officials to reward small people.

Lord Bai also promised that when he returned to Beijing at the end of the year to report on his work, he would go to the Baoquan Bureau of the Ministry of Internal Affairs to ask for a master from the ninth grade for Zhang Yingquan, so that they could glorify their ancestors for the Zhang family. If the craftsman does this, it will be heavenly, and everyone laughs, thinking that kind words are not important.

The important thing is that the plaque that was made improvised has not yet dissipated the smell of paint, and there are four golden characters: Craftsman is an iron model

The five-product Fujian and Zhejiang casting made Bai Xianglong pro-title, and he applauded!

For a time, the Zhang family was a shopkeeper, a great talent and a model craftsman, and he was a household name in Jin County.
