Invasion of alien beasts

Regarding the usefulness of ironware and gunpowder, Ding Wang asked Nuoqi to talk to Langton alone. Langton also realized the usefulness of these stones. The chances of defeat by the trespasser become greater.

Since these iron ore and sulfur were discovered by the vegetarian orcs, they were allowed to mine the ore, and some powerful orc warriors were found to help.The place where the iron ore and sulfur were found is a steep mountain forest, and there are no large beasts, so there is no need to worry about their safety.

However, although they had iron ore, they still could not start refining pig iron, because the production of the crucible used to smelt iron was very difficult.

Using pottery clay to mix porcelain clay and then thickening it is correct in theory, but it becomes extremely difficult in practice. Often the outside is cracked or the inside is not dry. Gass and Carlo are already proficient in making pottery. It worked, but after trying several times in a row, they couldn't make the crucible that Li Qingze needed.

Time was running out, and Ding Hao and Ding Wang had no time to take care of their shop. After handing it over to Owen and Eddie, they squatted in the pottery kiln all day long to study the making of crucibles. It was not easy to make, and they tried many methods, but they all ended in failure.

Li Qingze couldn't sit still anymore, he came to the pottery kiln to check those failed crucibles, "We must find a way to make the fire more evenly..."

"We also thought about it...but the inner wall is too thick, and the heat is too uneven, unless the inside and outside are roasted together." Ding Wang was also very helpless.

"Since the inner wall is so thick and porcelain clay is added, there shouldn't be any fear of it being cracked by the fire, right? Can't it just be baked directly on the fire?" Ding Hao asked curiously.

"It should work..." Ding Wang said uncertainly, "But you can give it a try."

Anyway, I have failed so many times, so let me treat a dead horse as a living horse doctor once.

"Why don't you call Uncle Sanger and let him breathe fire?" Sanger is a fire dragon, who can freely control the power and temperature of the flame. Ding Hao has personally seen Sanger roast a lot of flames by himself before. Pheasant, maybe if you let Sanger breathe fire to roast the cauldron, maybe you can do it?

"Good idea." Ding Wang also felt that this method was feasible, and immediately asked someone to invite Sanger to come over.

Sanger and Mota are now in charge of the distribution of food for the orcs and dragons, and they are very busy, but they heard that Ding Hao and Ding Wang asked him for help, so they immediately entrusted the work to Mota and rushed over up.

With the help of Sanger, the production of the crucible finally improved. The high temperature and large amount of flames emitted by Sanger quickly turned a one-foot-deep crucible into a fiery red color, and the outer layer dried quickly. At this time, Sanger turned the fire to the inner wall, baking it alternately inside and out, and finally dried all its moisture.

However, the temperature of the crucible cannot be cooled immediately, so as not to cause it to break. They pushed the crucible into the pottery kiln with a wooden shovel, baked it slowly on a low fire for a while, then extinguished the fire, and then waited for the crucible to cool naturally. If it breaks, it is a success.

After thanking Sanger repeatedly for his help, several people waited patiently until the sun set, and the crucible finally cooled down and turned into pure black.

"It seems to be successful?" Ding Hao touched the crucible carefully, feeling extremely hard.

"Try it?" Ding Wang was a little impatient and wanted to seize the time to experiment with ironmaking because he had wasted several days without the crucible.

"Okay." Li Qingze and Pan Yue also had no objections. They knew the benefits of iron and wanted to refine iron as soon as possible.

What Li Qingze used was the cast iron method of the Tang Dynasty. First, he crushed the mined ore, then put it into a crucible, and then put some plant ash.However, people in ancient times had a whole set of techniques for smelting, but they were all newbies in iron smelting, especially the two modern people, Ding Wang and Ding Hao, who didn't know how to look at the color of fire and how to distinguish molten iron. Mastering the heat and the fineness of the molten iron, the two people who were disgusted could only squat aside and watch Li Qingze and Pan Yue discuss with each other how to make iron.

Hard work paid off, they struggled all night, after three or four failures, Li Qingze and Pan Yue gradually grasped the pattern, finally a small pot of molten pig iron was smelted, and they poured the molten iron into a mold made of hardwood , After the molten iron solidified, the first piece of pig iron on this planet was born.

"Great!" Ding Hao couldn't help cheering.

"Successful!" A satisfied smile appeared on Li Qingze's face.

The joy of success made several people excited for a while, but soon, the negative effects of staying up all night surfaced, and the four of them felt a little tired, so they handed the pig iron to Gus and Carlo for preservation. Only then went home to rest.

At this time, it was almost dawn. When Ding Hao returned home, he found that Langton was not there, and the bed was neatly arranged. Did Langton go out early in the morning?

Because of being too tired, Ding Hao didn't think about it, he took a quick wash with the hot water on the stove, and then got into the quilt and fell into a deep sleep.
