With the addition of "glazed stone", the surface of porcelain will become smoother, more beautiful and more durable than pottery.

When he followed Emperor Wen to inspect Rong County, Qin Hao discovered that there were quartz mines and mica mines on the mountains, but he did not have time to explore the reserves at that time. After a few days of rough exploration, he found that the reserves of quartz mines and mica mines near Rong County were quite amazing. After ten years of use,

It's definitely no problem.

In the future, after the mineral deposits here are mined, porcelain production in Rong County will also have reached a scale that will be enough to offset the cost of purchasing and transportation from other places.

Later, Qin Hao recruited a group of strong laborers to go into the mountains to mine. This time, with the pearls and jade from the kiln in front, the common people rushed to sign up one by one. Qin Hao no longer needed to rely on those local families to obtain the common people.

of trust.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! The destructive power of man is amazing. In just half a month, a huge hole was dug out of a mountain, and those quartz mines

, the mica ore was also transported to the edge of the Minjiang River.

Cheng Shaoshang is tinkering in front of a row of weird machinery. This is a hydraulic gravel device she designed. This set of machinery is divided into two parts. The first part is a gravel machine, which is lowered into circular stone troughs.

Above is a stone hammer hoisted by a rope. The power of the stone hammer comes from the rapid water flow of the Min River. The rope of the stone hammer is pushed through the gear to initially crush the ore.

The second part is the stone crusher. The ore crushed by the stone crusher is crushed into powder through two huge stone mills. The power source is also water conservancy.

The pool at the back is a washing device. The powder is put into it, and then some clean water is injected. After the impurities are removed, these thick muddy water are the key materials for making porcelain. They are mixed with kaolin and then fired.

, you can get porcelain.

"How is it?" Qin Hao took out his handkerchief and wiped the sweat from Cheng Shaoshang's forehead.

Cheng Shaoshang chuckled and said proudly: "There will definitely be no problem this time."

Seeing that Cheng Shaoshang was so confident, Qin Hao waved his hand to indicate that the experiment could be carried out. The craftsmen opened the gate on the riverside, and the rapid water was introduced into a small reservoir. Driven by the water flow, the first part of the gravel crusher started

, the stone hammer hits the stone trough with a small force, and gravel will fly out from time to time, but there is nothing we can do about it. After all, it is just a relatively simple first-generation industrial product. It would be good to ensure industrial production. Anyway, those gravels are not

It won't kill anyone, but it will only hurt a little.

Soon, the first batch of ore crushing process was completed. The craftsmen closed the water inlet valve of the reservoir. Gradually, the stone hammers lost power and stopped moving.

Qin Hao picked up the gravel and inspected it, nodding with satisfaction: "Well, the effect of the gravel this time is much better than last time."

Cheng Shaoshang raised her chin proudly. Her talent was beyond words. Just relying on some simple physics and mathematics knowledge taught by Qin Hao, she was able to lead the craftsmen to create such a large-scale water conservancy mechanical device. It was already possible.

It's described as genius.

The subsequent stone crushing machine also performed well. Even if the experiment was successful, this device can be mass-produced.

At the same time, the training of craftsmen has also achieved certain results. Qin Hao asked them to separate all the processes and teach them. Each person only learns two to three processes. These kiln workers know the future. This is the basis for their livelihood. They learn one by one.

Enthusiasm is high.

Although they couldn't understand why they did this, it was not difficult to follow the example. After learning for more than half a month, it was enough to be used as an apprentice helper.

Everything was ready, and after a month of preparation, Qin Hao finally announced that the kiln could be opened for firing.

The production of porcelain is very complicated. There are seventy processes from the initial mining to the final baking.

When the kiln was opened for the first time, several common bowls and dishes were made, which were also relatively easy to make. With the blank making, glazing and other processes in place, the first batch of rough blanks were carefully placed into the kiln.

"Seal the kiln!"

The key to firing porcelain is the temperature. The temperature must reach above 1200 degrees Celsius. By sealing the kiln mouth, the temperature can be effectively maintained.

The kiln entrance is blocked, leaving only a firewood refilling port and an air inlet. The craftsman can only use the air inlet to observe the temperature changes in the kiln to decide whether to add firewood or remove the fire. This is a type of work that requires experience.

, the yield rate of a kiln of porcelain is largely controlled by him.

"ignition!"

As the pine wood in the kiln was ignited, the porcelain in the kiln gradually underwent some changes that were difficult to discern with the naked eye under the firelight.

The entire firing process takes a day and a night. Logically speaking, except for the craftsmen who add firewood and watch the fire, everyone else can go back to rest, but many people still stay spontaneously.

They also knew that they could not help much, but they could only use this behavior to pray to God and pray that the porcelain kiln would be successful so that they could continue to work in the kiln.

Tian Laowen was one of them. Aunt Wang had already told him about a woman who was a widow from the next town. In the Han Dynasty, a widow was nothing at home, not to mention that the widow was actually very pretty.

"God bless it, it will definitely come true. Lord Qin will be blessed with abundant wealth, and it will also give us hope in these hard days."
