Use oiled paper that is relatively easy to burn, wrap a fixed amount of gunpowder into a small packet, and put the gunpowder bag directly into it when filling the gunpowder, which not only saves time, but also ensures that there will be neither more nor less.

Such a genius idea, so that the firearms factory craftsman leader Bourne, admired Gao Han not want, Gao Han very calmly accepted the other party's admiration, and then told the other party that the quality and quantity of these gunpowder is the weapon to ensure the lethality of their own musket, the ratio of gunpowder is slightly different, the lethality effect will be different, if you can grasp this, then even if the users of the musket have other choices when using projectile gunpowder, they will definitely prefer this kind of convenient and worry-free gunpowder projectile from the factory.

A first-class firearms factory, manufactured to the standard! Gao Han wanted to tell the other party this, but, for the sake of the other party being a fan, he swallowed it - he couldn't be cheaper.

In any case, those who had traded in the old and got new muskets from the firearms factory became the beneficiaries of this improved musket and standardized ammunition, and, according to the information they fed back, although these firearms could not be compared with the standard firearms produced in the Kingdom of Portugal, they were already much better than those made in other places, and other places in these people's mouths also included the Ming Dynasty's Zuo Bureau.

Gao Han is very proud of this, but it is a pity that the output of his small factory is too low, and because of the material, he is not optimistic about the service life of this musket.

"It's smoking!"

As puffs of green smoke rose from the strange building of the firearms factory, someone finally realized that it was a stove, but it was just a little too big.

Is it big? Gao Han really doesn't think it's big, or, compared to this era, it's a little bigger, but, compared with the molten steel produced, this furnace, he can only say, this is also a blast furnace?

In terms of the fire resistance of the furnace, Gao Han has made a lot of explanations to Liu Ru, the temperature is not reached, and everything is in vain, however, with the ignition of the furnace, it seems that Liu Ru still grasps this relatively tightly, and the craftsmen of the Ming Dynasty have no lack of wisdom, but there are too few places where their wisdom is needed.

The craftsmen of the first furnace carefully used about 300 kilograms of iron, and under her command, the craftsmen put the ironware in, and then as the furnace ignited, all the craftsmen cheered as they turned into molten iron in the furnace.

There are so many molten iron, this is definitely a rare scene in any blacksmith shop, and when the temperature reaches a sufficient level, the oxidant and slag agent that have been prepared have long been added to it, seeing the tumbling molten iron quieted down, everyone carefully baked it, charcoal, a few blacksmiths bare-chested these slowly shaped molten iron into strips, into ingots, and finally, in a burst of quenched white mist, pieces of steel ingots appeared in front of everyone.

The first quenching is successful.

Liu Ru directed the whole process, and it wasn't until the ingots were placed in front of her that she completely put her heart down - finally lived up to his trust.

Three hundred kilograms of iron, the final refining of steel, almost two hundred kilograms, the conversion rate is only two-thirds, but Liu Ru is already very satisfied, such efficiency, such a cost, can refine such steel, or that sentence, this is simply a stone into alchemy, you know, as long as there are enough manpower, this furnace can even be smelted here for twelve hours without stopping, as long as the raw materials can keep up, it is not difficult to even smelt thousands of kilograms of steel a day.

The steel ingots were sent to the firearms factory, and the craftsmen Byrne and Chance, who were now leading the firearms factory, were very sure of the quality of the steel, and when they learned that the steel was made in a furnace like that next door to them, the two of them widened their mouths and couldn't believe it.

Bourne even wanted to visit the furnace with great interest, when he was building the furnace, he didn't care at all, but at the moment he wanted to care, but there was no chance, Liu Ru clearly told him, except for the blacksmith on duty, the furnace is now basically a tall person in charge, outsiders want to see it, it is absolutely impossible.

In fact, after determining that this steel could be made in this way, Liu Ruye's first reaction was to control all the workers and blacksmiths on the spot, they witnessed all this, what if the secret was revealed?

The blacksmiths are easy to control, after all, they are all craftsmen who made a register of the imperial court, and they were found by Qian Lianghu from various channels, but those workers are not easy to do!

The solution of this matter was solved by the blacksmiths, and those workers, after experiencing the forging of the first furnace, Jinyiwei found them, gave them a sum of money, and asked them to leave Haojingao, without even saying a reason, with Jinyiwei's notoriety, if these people knew what to do, they naturally kept silent about the things here, and, like those masons who built this road, even if they talked nonsense, they didn't have much substantive to say.

Where do the blacksmiths have few sons and apprentices, since these idlers have been sent away, then, their sons and apprentices have to take on the task of smelting, the lifeblood and livelihood of these craftsmen are controlled in the hands of the government, to be exact, now they are all controlled in the hands of Jinyiwei, from Jinyiwei's eyes, they can be used as half of their own people, naturally there is no need to worry too much.

Liu Ru even promised these blacksmiths that the household registration of these people could be transferred to the rule of Jinyiwei, as long as they performed well and worked diligently for Jinyiwei, it was possible for them to get rid of this cheap status in the future!

The blacksmiths didn't believe it or not, but when Zhang Chunmei appeared in front of them with Jinyiwei and revealed their identities, these blacksmiths immediately believed it, their craft has always been to do things for the official family, and there are many times when they are requisitioned, but they can give enough money and promise to leave the official family, they really met a few, with the promise of Jinyiwei, let alone confidentiality, even if others want to leak secrets, I'm afraid they won't do it, isn't this cutting off everyone's livelihood and hope? ?

"Thousands of kilograms?"

When she heard that Liu Ru was relieved to report the good news, Gao Han really couldn't bear to hit her enthusiasm, what can she do with this amount, she will continue to produce day and night, and even ensure that there will be absolutely no accidents, only twenty or thirty thousand kilograms a month, that is, twenty or thirty tons, not to mention making cannons, even if you make muskets, it is enough to choke.
