Among the five hundred craftsmen, in addition to the carpenter, there are the most blacksmiths and casters.

Liu Hong gradually handed over the drawings in his hand to them for circulation.

There are four drawings, two of which are broken downs, the first is an object shaped like an iron hammer, and the second is a thick cylinder, hollow with a hole underneath.

A few younger craftsmen were quick to see why.

"Master Hou, are you going to create a new weapon for Jingying? But look at it smallly, this is an iron hammer! The young man scratched his head and embarrassedly handed over the drawings to a few old craftsmen behind him.

Liu Hong gradually smiled and did not answer, what kind of iron hammer, this is a must-have artifact for every household in the eighties and nineties in the later generations.

The old grandson of the craftsman is almost fifty years old, and he has been making iron tools all his life, and his hands are full of thick calluses.

He frowned deeply, staring at the iron hammer-like drawing for a long time, until he turned to the second page of the decomposition instructions, and seemed to see a coal word, and then he had an idea.

"Master Hou, is this object related to the coal and stone you pulled over?" Old Sun asked tentatively.

"Well, it's smart, not like these stunned blues! This thing is called a briquette machine! Liu Hong gradually pointed to the first drawing and said.

Old-fashioned twelve-hole handmade briquette machine, this thing he has not only seen, but also used.

When he was a teenager, the orphanage used briquettes to make fires by hand in order to save money.

Buy the pulverized coal from the briquette factory and crush it with a machine, mix a small amount of clay with water, put the briquette machine into the slime and press down hard until the slime fills the briquette body, and then dip it in the wood foam.

Press the head of the briquette machine hard in the open space, and a fresh briquette will be beaten, and it will be dried in the sun for two days, and you can live and heat up.

Another drawing is a briquette furnace, which is simpler, nothing more than making a hollow mold with a chassis, pouring it with molten iron, and then polishing it by a craftsman.

After listening to Liu Hongji's explanation, a group of blacksmiths and casters were all stunned and shocked!

Isn't Hou Ye from a military background? How do you still know our blacksmith's craft? Looking at Hou Ye's formation, has Hou Ye ever used this thing called a briquette machine?

Disastrous! Disastrous! A group of people even forgot their words, and they all watched Liu Hong's eyebrows gradually flutter and explain.

"Who has the confidence to make this thing?" After explaining, Liu Hong gradually said.

In fact, when I explained just now, several literate craftsmen had already read the decomposition of the drawings, although they were all simplified characters, but most of the characters at the end of the Ming Dynasty were no different from now.

The most difficult thing is the body of the briquette machine, the handle of the briquette machine is alive, and the twelve iron rods and the ball cover are also alive, and the combination of the two is responsible for pressing the slime into shape and pushing it out.

This is an old antique that has long been eliminated in later generations, but at the moment more than 300 years ago, it is enough to be called an epoch-making invention!

The most active young people just now wilted, and they had made simple objects such as hoes and sickles, and this thing, no!

"Master Hou, the old man may be able to give it a try!" The old grandson bowed and said humbly.

Your uncle is still your uncle! It's not okay for a bottle to be less than half a bottle dangling!

"It's easy to say, the drawings are here, you can all start work at the same time, whoever develops it first will be rewarded!

Well...... The reward is 500 taels of silver, and the household registration of the craftsman can be turned into a free body! Liu Hong gradually thought for a moment and said.

He had already received this privilege from Emperor Chongzhen, and this would also be a sharp weapon he used to motivate the craftsmen to be angry and strong.

Five hundred taels of silver is not enough to change a certain artisan family, but the abolition of the shackles of craftsman registration means that one's children no longer have to be bullied and poor all their lives like his old man.

He can participate in the imperial examination as an official, he can also do business, and he can even farm and harvest mulberry......

And now...... Hou Ye's words naturally count.

No one knows how much humiliation these craftsmen have endured, and that sentence alone is enough to drive all craftsmen crazy.

A group of young people took the drawings and instantly surrounded the old grandson, they hoped that the old grandson would give him advice, but the other peers all shook their heads, because this was simply impossible.

In the past 5,000 years, the handicraft has been passed down from teacher to teacher, this is the craft of people mixing rice and eating, unless it is their own son, how can it be passed on to outsiders?

"There are conditions for the expulsion of artisan households, and it is necessary to compile the skills mastered into a book and hand them over to the head of the stall for disposal."

Liu Hong gradually frowned slightly, for thousands of years, I don't know how many skills have been lost in the land of China, and most of the reasons are caused by this kind of teacher's oral tradition, and not paying attention to books and theories.

With the conditions of expulsion, even if you share what you have learned, there is nothing unfair about it, and your children don't have to be craftsmen anymore anyway.

In order for their descendants not to be bullied like them, most of the craftsmen do not care much.

In fact, the use of coal is not limited to honeycomb coal, after all, these are anthracite coals that do not produce much toxic gases, that is, they are burned in large chunks, and there is no big problem when paying attention to ventilation.

Honeycomb coal creates trouble, not only to knock the coal stone into pieces, but also to re-beat, the process is troublesome.

Fortunately, labor is really worthless, and most of the craftsmen in ancient times had the spirit of craftsmanship, unlike later generations who could cut corners, steal and play tricks, never be diligent and down-to-earth.

Moreover, the promotion of honeycomb coal is aimed at wealthy households, coal is more resistant to burning than charcoal, and the heat of burning is also higher than that of charcoal, and charcoal is not only more troublesome to make, but also the cost is high and bizarre.

At the end of the Ming Dynasty, ten catties of charcoal cost two dollars of silver, but what about coal? In terms of output, one hundred catties is less than five hundred copper coins.

A discus can be placed on the top of the briquette stove, a hole can be opened on the side, and an exhaust pipe leads to the window, in addition to heating, the upper part can also be used to boil water, hot tea, and cook, and one stove can be used for several purposes.

Besides, honeycomb coal and briquette stove are not much taller than a charcoal basin in the house!

Liu Hongjian can almost imagine that if this thing is really made, it can definitely make money.

Another method is for ordinary people's economic and practical type, which is nothing more than to build a stove with mud and stones, and quickly knock the large coal into small ones to use.

After explaining many matters, seeing that it was not too early, Liu Hong gradually prepared to go home in the gratitude of everyone.

"Oh yes, Lao Yan, the three of you will remember to come to this Hou Mansion later, it's going to be the New Year, drink some fun together!" Liu Hong gradually got on the horse and said.

"The lower officials obey the order, even if the adults don't say it, the three of them also have something to report to the adults!" Yan Yingyuan gave it away!

"What kind of official, a few of us are still so polite, if there is something to say at night, I will go first!"

After speaking, Liu Hong gradually patted his horse and walked home.
