"I said, uncle, shouldn't we ask someone from Baoyuan Bureau to do this money minting? We are making weapons here!"

When Wang Bing found Zhao Shizhen with the set of new currency drawings approved by the fat man, the firearm expert who was busy studying metal shell bullets was a little troublesome.

"I said to Brother Zhao, you really have to do this! Not to mention that you have more experience in using this water hammer, just say that the steel used in this mold is not anywhere else except our military battle!"

Since we want to mint new coins, whether it is casting or stamping, the first thing is to make molds.

However, the mold material required by this stamping method is much higher than the casting method. The entire Ming Dynasty can now provide such qualified materials.

Therefore, based on the principle of one guest not bothering the two masters, Wang Bing also handed over the mold making of the new coins to the military battle.

"Don't worry, uncle, I will use the best materials to make this mold for you as soon as possible!"

Compared with Zhao Shizhen who was troublesome, Zhang Hong, the eunuch in charge of military affairs, is much more attentive.

Speaking of which, because of the punishment for the reform of the Flintlock Gun, Zhang Hong held a grudge against Wang Bing and often thought about revenge. However, Wang Bing's favor has always been unabated, but he has not found any chance.

Now Wang Bing has become the hereditary champion Marquis above the Duke of the Kingdom, and has long become an existence he cannot afford to offend, so this revenge can only be extinguished.

Now, after finally seeing Wang Bing come to the military battle to "do things" again, thinking of moving from the position of eunuch in charge of the military battle, his attitude was a world of difference compared to when Wang Bing sent Zhao Shizhen to the military battle.

"Haha, then I'll trouble Eunuch Zhang. This is an important matter. You must do it according to the drawings without any mistakes. In addition, the drawings must not be leaked, otherwise your Majesty will pursue them..."

...

"Not bad, Eunuch Zhang has done a good job this time, thank you for your hard work!"

Ten days later, looking at the pattern printed on the steel working mold in front of him that could be used for actual production, Wang Bing couldn't help but nodded with satisfaction.

Unlike the previous casting method, the new silver coins are made of stamping and require huge force. Therefore, the material of this mold is naturally impossible to use the copper, lead, ceramic and other materials used to make the currency mold.

It is not that simple to make this steel mold. First, you have to use wax to make a wax film, then use wax mold to make a gypsum mold, and then use gypsum mold to make a copper mold. Finally, you can turn the steel mold with a copper mold.

And there is still continuous refining in the middle, so in this era of pure handicrafts, this complete mold can be made in ten days, and this macro is indeed considered to be attentive.

"Thank you, uncle, for your praise. You are the one who is the one who is responsible for serving Your Majesty..."

After receiving Wang Bing's praise, Zhang Hong quickly bowed to the palace with humility."

"Brother Zhao, work, this mold has been made, and the installation and debugging of this punch and mold will depend on you!"

After making the mold, the next step is to install the mold on the punch for debugging.

Don’t think that you can stamp directly with a mold. This set of new coins is different in size, thickness and even in materials, so the strength of each punch naturally needs to be adjusted slowly.

"Haha, Brother Yu wants to see what is extraordinary about the silver coins cast by the uncle in this way."

Although this time it is no longer a firearm, Zhao Shizhen, as a technical mate, was also very curious about the new coins mentioned by Wang Bing. So after taking the mold, he did not delay and directly chose a punch to start to take people to install and debug.

"Eunuch Zhang, start smelting!"

While Zhao Shizhen was leading people to install and debug molds and punches, Wang Bing also began to smel the materials of the new coin.

...

"I've weighed it for sure, nine cents of silver and one cent of copper, not more or less!"

By the boiling heat, Wang Bing looked at the craftsman who was weighing silver, but he again told him.

Although the smelting material was to mint silver coins, Wang Bing did not intend to use sterling silver. First, the silver is soft, and the addition of copper material can increase the hardness and prevent it from wear and deformation during circulation. Second, it is naturally to "make money".

Soon, under the operation of several craftsmen, a furnace of silver-copper alloy was melted. Then, the silver-copper melt was cast into silver plates. After it cooled, it was crushed into silver pieces for use.

Of course, during this crushing process, small round silver pieces have to be cut out to weigh them to ensure that their thickness can meet the weight of silver coins of various specifications.

"Okay, let's heat up again and then you can stamp it!"

Since it was a trial-cast sample coin, the silver was not melted this time, only 500 taels. Therefore, it didn't take much time to make it into a bad cake of qualified thickness in the hands of these skilled royal craftsmen.

...

"Bang!"

With a light sound, a silver coin with uniform tooth prints on the edge fell off the modified punch with a "ding" sound.

"No, the force is too strong, it needs to be reduced a little!"

After picking up the first silver ball of the Ming Dynasty, Wang Bing couldn't help but frown, and then ordered the craftsmen to adjust the strength of the punching water hammer.

"No, this time the power is too small again, and the patterns are not clear enough!"

"Adjust adjust, reduce the strength a little more..."

"Well, this time just happens to be the right one, so keep this strength!"

After all, it is not a punching machine in later generations, and its strength can be controlled accurately at will, so even this seemingly simple step still wastes several silver pieces to adjust the strength.

"Uncle Guo, is this our new money for the Ming Dynasty?"

He picked up an exquisite one or two dragon silver, and Zhao Shizhen was not very optimistic about Wang Bing's new currency making method, but now he couldn't help but look surprised.

"How about it, Brother Zhao, this silver coin is worth one or two silver taels?"

Ignoring Zhao Shizhen's surprise, Wang Bing asked Qi about the value of the silver coin.

"It's worth it, of course it's worth it! Don't say one or two liang, it's worth it!"

After reading this exquisite dragon silver several times, Zhao Shizhen, a "technical resident", was not in charge of the company, so he gave a price of two taels.

"Dear masters, what do you think!"

Seeing that Zhao Shizhen's "technical mate" had no reference value at all, Wang Bing had to turn his head and look at several craftsmen involved in the production of silver coins.
