Next, the winter cold prevention work of Luoyang County has become the top priority, of course, approaching the middle of winter, Luoyang County is facing more than one problem, but how to prevent the cold is indeed a major problem that Jin Jue has to solve first.

In order to solve this problem as soon as possible, the only thing Jin Jue thinks about now is to fire red bricks. This method was actually the first time he stepped into Luoyang County and saw that so many people had gathered in the city. There were so many Yellow Turban troops who defected to him, and even if a small county town had enough food, it could not accommodate so many people.

It was from that time that Jin Jue had already thought of a solution.

Before Jin Jue crossed, he grew up in the city from childhood to adulthood, an ordinary worker's family, and he also studied computer science, and he usually loved ancient Chinese history, especially in the late Eastern Han Dynasty, and was particularly obsessed with this history until the end of the Three Kingdoms.

Therefore, Jin Jue has only seen red bricks, and has searched for relevant information on red bricks on Baidu, as for how to build a kiln and how to fire, he is a complete layman.

Red bricks were first invented by the ancient Babylonians. In general, clay, shale, coal gangue, etc. are used as raw materials.

However, this raw material is said to be the recipe used in later firing, if in ancient times, according to the current conditions of Luoyang County, it can only be made from clay, ordinary clay and slag.

The reason why shale and gangue cannot be used is because of this step.

There are no rivers in Luoyang County that have too much water, and now that winter is approaching, the flow of the rivers has not only been greatly reduced, but also may freeze at any time. It is impossible to completely crush the above two raw materials by manpower alone.

The step of making bricks is the simplest.

Because, nowadays, the most important thing in the city of Lüyang is manpower, as long as the carpenters in the city make enough, simple and easy-to-operate billet grinding tools, the speed of this work will be greatly accelerated. Not to mention young adults, even the elderly and children over 10 years old can do this job. Therefore, Jin Jue planned to let the young Zhuang be responsible for collecting and transporting raw materials, and the elderly and children were responsible for making bricks.

The biggest difficulty in the remaining steps of firing red bricks is where to build the kiln and how to control the temperature.

After the bricks are dried, they are sintered and fixed by firing them with an oxidation flame at a temperature of about 900 degrees Celsius. In this step, if charcoal is used alone, how many mountains and forests will have to be destroyed.

In order to meet the Hanzhong army, Jin Jue ordered the soldiers to cut down trees to block the road, which was a last resort. However, when firing red bricks, there is no need to use charcoal.

The fuel source that replaces charcoal is naturally coal.

The county of Luoyang in this time and space is many times wider than the county of Luoyang County in later generations, so according to the memory of later generations, Jin Jue has already realized that Liu Xiongming has found the coal mine that was only discovered by later generations before this. There are mostly metal deposits around Luoyang County, but it does not mean that there are no coal mines here, but there are no super-large or large coal mines.

Not to mention, Liu Xiongming, a county man, has no other skills, but the ability to find mineral deposits does seem to be innate. He looked for nearby old mountain people and experienced prospectors, but he didn't find a coal mine, but he personally went out and not only found the ore that Jin Jue was looking for, but also this mine was actually an open-pit mine. The only pity is that the quality of the coal in the coal mine is slightly worse.

Also, in Jin Jue's impression, there seems to be no coal mine here in later generations. Perhaps, it is because the coal reserves here are too low and too easy to mine, so they have been dug up early!

In any case, in the month that Jin Jue led the troops to the expedition, Liu Xiongming followed his instructions to treat the last batch of captured Hanzhong soldiers as miners, and in more than half a month after finding the coal mine, the coal mine dug up and transported to Luoyang County has exceeded 100,000 stones.

……

After lunch, Jin Jue said goodbye to the second elder and first went to meet the craftsmen in the former Luoyang County and the Yellow Turban Army that Liu Xiongming had summoned for him.

Or at the east gate, after Jin Jue was carried to the place by his subordinates with a sliding rod, he raised his eyes and looked, hey, good guy, he never thought that there were already a thousand craftsmen gathered here.

"Childe, you're here." It was Wei Dan who stepped forward to speak, he bowed his hand, and then introduced: "Liu Juncheng took Fu Gongcao and Wuguan Peng to familiarize themselves with the things in Luoyang County. ”

"Oh! Master Wei, this son wants to ask you, the people gathered here now are all craftsmen, and there are no miscellaneous apprentices in them? Jin Jue nodded, looked at so many people, and asked.

Wei Dan didn't quite understand why Jin Jue asked this, but how he replied: "Yes, Childe, there are naturally craftsmen here, and you ordered all the craftsmen in Luoyang County to gather, naturally they are all craftsmen!" ”

Since Jin Jue appeared, all the craftsmen present consciously closed their mouths, facing the direction where Jin Jue was located, and stood there with their heads bowed, no one dared to make any noise. Although Jin Jue does not have the spirit of a king, his identity is there, and the status of craftsmen in ancient times is not high, in fact, it can be said that he is the lowest among the four people, so they will show such awe to Jin Wei.

However, this also has an advantage, the scene is very quiet, and when Jin Jue speaks, he doesn't need to make too much noise.

This is not bad, because Jin Jue asked Liu Xiongming in advance to warn these craftsmen who were suddenly summoned that when they saw him, they didn't need to bow down, otherwise, as soon as he appeared just now, all the people present would kneel in front of him except Wei Dan.

Jin Jue nodded, indicating that he knew, and then he asked loudly to all the craftsmen present: "Everyone, my son wants to ask, which of you can fire bricks, red bricks and blue bricks." All the people who would meet stood on the left hand side of Ben Gongzi. ”

Fearing that there would be no one in the room, he raised his left hand and pointed to his left as he spoke.

Hulala, more than thirty craftsmen wearing yellow scarves walked out of the crowd with their heads bowed and came to Jin Jue's left hand side.

"Then all the carpenters come to the right-hand side!" After Jin Jue finished speaking, he raised his right hand again and pointed to the right hand.

This time there were even more people, more than two hundred, after all, among the ancient craftsmen, carpenter was the basic type of work.

The reason why there are so many craftsmen in the county seat of Luoyang County is because the Yellow Turban Army that can survive to this day is either a soldier or a craftsman.
