"Good boy, I heard that you can burn lime? Why didn't you tell me earlier? Otherwise, our families would be able to build houses, right?"
The person who spoke this time was an uncle of Qin Jun. He should be from the eldest family, that is, the child of his grandfather Qin Dashan's eldest brother.
They are all from the same family, and there are absolutely no five blessings.
It's just that he is only fourteen years old now, and these elders trust him so much?
"Isn't it strange? Why do a group of us believe so much in the words of a naughty kid like you?"
At this moment, Qin Zheng, the captain of the village, came over and said.
Qin Jun looked at Qin Zheng. Even if he was the captain, he was still skinny.
The man in his forties looked a little dry now, especially his face, which was full of wrinkles.
The common people of this era, whether they are village cadres or not, are all like bears, like their ribs turned into sperm.
"Because it doesn't cost anything, as long as it doesn't cost us anything, we can do anything. As long as it gives us a hope of building a house, we will do it!"
Looking at Qin Zheng with a cheerful face, Qin Jun understood.
It was very difficult for the villagers to make money during this period. Apart from the little money distributed by the village at the end of the year, there was no income whatsoever.
Just like Qin Jun's family, there are seven adults in the family. They have been busy all year long and are reluctant to waste a centimeter. In this way, they only divided about 130 yuan.
Seven people a year! What can you do with just such a small amount of money?
You don’t have to spend money on oil and salt at home. When you buy salt or matches, you can just exchange eggs for some money.
However, it costs money to buy cloth, it costs money to send children to school, and it also costs money to see a doctor and take medicine!
If there is another personal relationship, the cost will be even higher.
Especially getting married and having children cost a lot of money.
This is a burden for farmers who only make so little money a year.
Therefore, Qin Jun just said that he had a way to build a house without spending money. With just this sentence, he attracted all the men in the village who could work.
Regardless of whether it works or not, give it a try!
Just like that, Qin Jun was in a daze and was picked up by men from a village.
Fortunately, he was not a real fourteen-year-old, and he had a complete plan when he deceived his father.
Now that someone is helping with the work, the lime kiln can really be repaired.
He didn't want to build a lime kiln from scratch, because he could use a small blast furnace outside the village.
Those non-standard small blast furnaces have been almost destroyed, leaving only a base.
The small blast furnace was built on a hillside. The blast furnace above has disappeared, leaving only a furnace bottom.
It just so happened that Qin Jun wanted to use this foundation.
As long as it is trimmed and can be stuffed with firewood to start a fire, everything else is not a problem.
The lime kilns that can appear in rural areas must be earth kilns, shaped like pots and stoves.
As for those unqualified small blast furnaces, the furnace mouths with ignition below are very suitable for lime kilns.
After the modification, the bottom of the kiln was a ignition channel built with herringbone strips and stone barriers.
Between the strips of stone, there are pockmarked stone eggs. The pockmarked stone is fire-resistant and should not be burned or deformed.
In this way, as long as the ruins of the small blast furnace are cleared out, it will be a qualified lime kiln.
And the size is not small. Generally, the diameter of the bottom is about two meters and the depth is about two and a half meters.
The diameter of the kiln mouth at the ground level is about one and a half meters, and the top of the kiln mouth is generally about one meter in diameter, depending on the amount of firing.
If such a kiln is completely filled, it can burn more than ten tons of lime at a time, which is 20,000 to 30,000 kilograms.
Such a lime kiln is sufficient.
However, burning lime is a technical job with strict procedures.
Especially for the control of heat, the experience of the kiln firing master is the key.
At the same time, kiln burning is a laborious job. Whether it is quarrying, transporting stone, loading the kiln, or taking it out of the kiln, it is very hard.
The general process of firing a kiln is: first lay thorns, hard miscellaneous firewood, and less bituminous coal on the bottom of the kiln.
Then there is a layer of coal and a layer of limestone.
A kiln of ashes usually takes about seven days from ignition to completion.
The burned lime must be discharged from the kiln again in the order in which it is placed.
Cinder needs to be cleaned while leaving the kiln.
It’s all physical work anyway, and it’s also dirty work.
If it weren't for the stuttering, Qin Jun really wouldn't want to do this.
It's better now. There are people listening to his instructions and he doesn't have to do anything. This is very comfortable.
There were people to help repair the kiln, and there were people to help lay the limestone.
By the way, before the limestone is put into the kiln, it needs to be broken first. Don't let too big limestone into the kiln, which will make it difficult to bake.
Of course, there are particularities in how to place coal and limestone in the kiln.
Generally, the charcoal is sold as economically as possible, and all the limestone can be burned thoroughly. This is the technology.
If Qin Jun hadn't fired porcelain kilns before, he really wasn't sure he could play in lime kilns.
"Third brother, are you sure this is enough? Our family has been saving up for a year, and we are not even willing to burn it in this winter. Today, it is all used to burn lime."
Seeing pieces of coal cakes being put into the kiln, followed by a large amount of bluestone, Qin Zhihe was still a little uneasy.
"Anyway, these raw coals cost nothing. They were picked up for free. If the firing fails, there is no loss. If you are really reluctant to part with them, how about giving this kiln to my uncle?"
Qin Jun is not used to his father, because there are many families queuing up, waiting for him to help burn the kilns.
For example, his uncle, second uncle, and even grandpa are already in line.
Qin Zhihe's mouth trembled a few times, he was angry.
However, now he doesn't dare to beat and scold this third son at will, because now he is really like that when he directs people to work.
Anyway, no matter how he looked at it, he felt that he was worse than those old masters in the commune lime kiln.
"Fire it up, light it up!"
The wood that had been prepared long ago was put directly into the bottom of the kiln, and with some kindling firewood, it was quickly burning.
"Don't worry. Burning lime only requires a low temperature of 900 degrees. Even if you use wood, it will not fail."
Looking at his father's face, his expression changed unexpectedly, and he didn't know whether it was because of the firelight or because his blood pressure had increased.
Anyway, Qin Jun was a little worried, so he had to comfort him.
What he said is not nonsense, because the wood used in a firewood kiln can raise the temperature inside the kiln to more than a thousand degrees.
That is firing porcelain, which requires more difficult technology to control temperature.
In particular, the placement of porcelain requires special design, otherwise it will be heated unevenly and the porcelain will be easily burned.
Compared with firing porcelain, firing lime is too simple.
If he doesn't want to save some coal, he doesn't need to design it specially, he can just place it randomly.
Just use a layer of coal and a layer of limestone and burn it directly like ordinary workers.
That is to make lime for yourself. There is not much coal, so save it if you can!
Although these coals are picked up, they are not easy to pick up!
Otherwise, he would not have been able to design a unique smoking channel.
If the flue is well designed, the coal seam laid will burn easily.
With such a strong fire and the characteristics of the original small blast furnace - heat preservation, it is really not difficult to bake a kiln of lime.
It took a busy day to dig out a kiln of limestone.
Now the limestone goes into the kiln and the wood at the bottom of the kiln ignites the coal.
This can be seen because the dome like a tomb formed above the lime kiln after sealing it with mud has begun to smoke.
This is considered successful. As long as there is smoke from the top of the kiln, a flue will be formed in the lime kiln, so that the coal in the kiln can continue to burn.
As long as the coal in the kiln does not burn out, the kiln lime will be stable.
"Xiaojun, this kiln will be fired for seven days?"
I don't know when Qin Zheng came to Qin Jun again.
"It shouldn't take more than seven days. The ventilation duct I designed is pretty good. Plus we don't have much lime to bake, so it will take about three or four days to produce a kiln."
Qin Jun also had no experience. He just speculated based on the temperature at which the porcelain was fired.
Judging from the position of the coal and limestone he placed, it should not take more than four days since all the limestone has been fired at a high temperature of 900 degrees.
If porcelain is fired, it usually takes two to seven days to complete depending on the type, size, quantity, and size of the kiln mouth.
In other words, it is simple, the quantity is small, and it can be fired successfully in at least two days.
A large and complex porcelain kiln is fired entirely with wood and takes no more than seven days.
Burning lime is simpler. As long as the coals are placed reasonably, with no layers in between, and the fire is not turned off, when the coals are burned out, the lime will definitely be fired successfully.
