For convenience, both the brick and porcelain kilns were built at the foot of the clay mines, not far from each other, but two or three kilometers from the residential area of Cancer Island.

Once he found the clay mine, Donner was able to have the thorns cut down the dwarf wood and make an easy path that could barely be accessed by a beast cart.

The preparation of the brick kiln was entrusted to a skilled master stonemason, who had extensive experience in building castles, so apart from the occasional visit to teach, Donner entrusted the daily work to this master.

When Donner and Jason arrived, Master Vaan was inspecting the entire brick kiln.

Donner remembers that when he was a child, many people in his hometown built their own kilns to burn bricks and build houses.

But in this other world, there has never been one. With more than ten years of stonemasonry career in Va'an, whether it is building castles, city walls or houses and other buildings, they are all polished into regular shapes with rocks and then used for masonry.

But he heard from Donner that the stone needed to build a house in the future could be kneaded with mud and fired in this kiln.

It's unbelievable, and if it's really successful, I don't know how much time I'll save when building a house in the future.

Therefore, Master Vaan has always been at a loss in his heart, worrying about whether the pirate leader will use his head to vent his anger if something happens to the firing bricks.

Today is the day when the kiln is expected to be opened to burn bricks, and Master Wa'an has told Donner before, so he also learned that Donner will come in person, and now he is anxiously checking the situation of the entire brick kiln according to Donner's previous request, for fear that there will be any omissions.

The brick factory is very large, mainly divided into three parts, divided by a path, the innermost part of the road is the brick kiln, one side is the site for mud making embryos, and on the other side is a row of thatched sheds, which are used to put shaped brick embryos, which are used to dry naturally into the kiln for firing.

Soon, a worker at the scene informed Master Waan that the head of the regiment was here.

Donner walked into the venue, and Wa'an greeted him with a sweat: "Captain, we are ready, just wait for your order, and we can enter the kiln to fire." ”

Looking at Wa'an's expression, Donner knew the master's nervousness, and said with relief at the moment: "Master Wa'an, don't worry, it doesn't matter if the firing fails, it doesn't matter if you don't succeed once, and if you don't succeed twice, you will do it three times, failure is the mother of success, just like burning porcelain, if you fail, try a few more times, we can always find a way." ”

Wa Ansheng was moved that in his career as a craftsman, those nobles would never have encouraged a craftsman so much.

If the things created are not satisfactory to the nobles, not to mention that there is no remuneration, a few whips are trivial, you must know that many craftsmen have lost their lives or been sold into slaves.

"Let's go! Let's go inside. Donner patted Master Vaan on the shoulder and led the way towards the brick kiln.

A brick looks quite simple, knead it with mud and put it in a kiln to fire. But in fact, it is quite complicated to make and calcine it from beginning to end.

Just talking about the mud used to make bricks, it is necessary to go through four steps: beating the soil, soaking the soil, mixing the mud, and waking up the mud to obtain the mud that can make the brick embryo.

Then to the billet making, it is necessary to go through several steps such as scraping, embryo mold, pulling, demoulding, shaping, stacking and storage, etc., before the green body of the same size can be made and can be fired in the kiln.

Therefore, such a small brick can only be formed by the hands of ten people.

It didn't take long for the Donner trio to arrive at their destination.

This brick kiln is a simple fire kiln, the whole is cylindrical, the brick kiln is not large, but it is still possible to fire more than 100,000 red bricks at a time.

Most of the space inside the kiln is used to place the brick embryo in the kiln pit, there is a T-shaped fire channel at the bottom of the brick kiln, and there is also a passage connecting the fire tunnel and the kiln pit outside, commonly known as the kiln coupon, which is used to transport fuel and burn the fire.

At this time, more than a dozen people were constantly busy, moving the dried bricks into the brick kiln.

Kiln loading is a very technical job, and there are strict rules for the stacking of brick embryos, and Donner has patiently taught these people how to do it.

When stacking the bricks, the middle of the fire path should be kept until there is a quarter of the top of the fire kiln, the bricks on both sides of the fire path begin to probe into the fire path in layers, and as the number of layers increases, the fire path will become narrower and narrower the higher it goes, until the bricks on both sides are connected together above the fire path and the fire path is closed.

In the whole process of loading the kiln, all the bricks should be stacked, leaving a gap of overfire, and they cannot be combined together, and when the kiln is full, the last work of capping will be done.

The capping is paved with those flawed bricks tightly without leaving gaps, and only needs to reserve a circle of fire holes along the kiln wall, that is, the chimney, and finally covered with yellow mud to seal the soil and flatten it.

Vaan followed behind Donner, while Jason looked at these things curiously, and after Donner carefully examined them from front to back, he turned to Master Vaan and said, "Let's start firing the kiln!"

Vaan carried out his orders relatively well, did exactly what he asked, and did not change any steps on his own initiative.

The workers were also very careful, and although there were some minor flaws, in Donner's opinion, they had done a good job and would not affect the firing of the bricks.

Allah arranged for someone to add wood to the kiln, light the fire and start firing the kiln.

These timbers are basically trees that have been cut down from the wasteland, and they can't make any furniture, doors and windows, but after drying, they can be used for burning bricks and porcelain.

The flames began to burn in the kiln, and the smell of resin came from the chimney.

The temperature required to fire bricks is slightly lower than that of porcelain, but it is also between 800 and 1,300 degrees. With wood as fuel, the temperature is raised relatively slowly, so the whole firing process lasts one to two days before the bricks are completely fired.

As he walked out, Donner instructed Master Waan on some matters, especially safety issues, in short, from the very beginning, he repeatedly told him to ensure the safe production of the brick kiln, and there should be no accidents that would lead to casualties.

Downer particularly emphasized that there are several safety production regulations he has formulated that no one can violate.

The rest of the brick kiln process is fine, but Donner's biggest concern is the kiln, after all, everything related to fire is dangerous. Another is to open the kiln when the time comes, and you must be careful to follow the steps, otherwise it will collapse if you don't do it well.

Not to mention the shortage of personnel on Cancer Island, even in Downer's concept of life, it is not allowed to have safety accidents due to improper production management under his management, resulting in personnel and property losses.

After carefully explaining to Master Vaan, Donner then took Jason and walked towards the porcelain kiln, he hadn't seen Yuri for many days, and he didn't know what the old alchemist was busy with these days.
