Rich and powerful

"If I can find your boss, I must have inspected it a long time ago! Let me demonstrate it face to face, and Mr. Yang will look carefully! If there is no problem, I will leave this work to you in the future!"

Yang Tiexin could only nod his head in agreement, he had originally intended to seek refuge with Lin Yun, after all, no one would have trouble with Yin Zi.

In addition, he still had to ask Lin Yun this time, so he didn't dare to refuse.

"Okay! Xiao Lao must have read it carefully!"

Lin Yun started to demonstrate. He first ignited the blast furnace, and when the temperature rose, he took out a basin of fine sand in a sack beside it.

This is just a demonstration, so it doesn't take much.

The old blacksmith was dumbfounded when he saw Lin Yun's flowing operation, and he was even more admirable in his heart.

He knows how hard it is to go around the blast furnace all day long, and it is simply not a job that ordinary people can do.

But Lin Yun can operate so skillfully, it can be seen that he must have worked a lot on weekdays.

This also indirectly proves that Lin Yun is different from ordinary rich sons.

It made Yang Tiexin praise in his heart that the master he will follow in the future does not have the common problems of rich sons, that is definitely something to be happy about.

Here, Lin Yun finished all the preparatory work. Turning his head, he saw a smile on the corner of Yang Tiexin's mouth, and asked, "Why is Mr. Yang laughing? Is there something happy? Tell me and share!"

Only then did Yang Tiexin come to his senses, and quickly waved his hands and said, "No!! Xiao Lao is just impressed by the master's skillful operation! After all, this is not an easy job!"

Lin Yun nodded and smiled, and said: "Mr. Yang will work hard with me in the future, and you will find that I know more things! It will definitely benefit you a lot!"

In fact, from the moment he planned to recruit the old blacksmith, Lin Yun had no intention of letting him go.

A person who has controlled a lot of his own technology must not let it go easily.

Otherwise, it will be very disadvantageous if one of your enemies or competitors buys you off in the future.

"Then thank you Mr. Lin! Xiao Lao must learn with humility!"

After about half an hour, the temperature of the blast furnace finally came up.

It was troublesome in ancient times. If it were in modern times, it would be very easy to increase the temperature of the blast furnace, at least it would not take so long.

Lin Yun got up and opened the lid of the blast furnace, and suddenly a wave of heat surged, and the crimson fire light reflected on his face, as if it had been plated with gold.

The old blacksmith cautiously came to the front of the stove, looking at the raging flames inside, he was secretly startled.

"Mr. Lin, how is the interior of this blast furnace designed? How can it preserve the heat so well? It's amazing!"

Yang Tiexin was very envious. If his blacksmith shop had such a blast furnace, his daily work efficiency would be greatly improved.

The higher the temperature, the better the effect of calcining the ironware, and the associated thing is that the impurities and air in the ironware can be squeezed out.

He can cut down on hitting with a hammer.

This seemingly inconspicuous benefit is definitely a chain reaction.

Lin Yun smiled and said: "Don't worry! As long as Mr. Yang is willing to do things for me, these are just trivial matters! You have to see clearly the next steps!"

"I brought this fine sand back from the dry sea in Taoyuan Town. There are very few impurities in it. After being calcined at high temperature, the fine sand will melt!"

Yang Tiexin was a little surprised, and said with emotion: "Xiao Lao is really ignorant, this is the first time I heard that fine sand can be smelted!"

These insignificant things are usually ignored by people. It is estimated that Yang Tiexin would never think of calcining fine sand in his life if Lin Yun didn't mention it.

In his opinion, it is a waste of charcoal.

He opened the door to do business, how much charcoal he consumed every day, and how many finished ironware he could forge.

If the loss is too great, but the benefit is not proportional, he will definitely not do it.

Not only him, but I am afraid that he is a businessman, and he would not do business at a loss.

Therefore, the technology provided by Lin Yun is definitely rare and valuable.

Lin Yun nodded and smiled, and continued: "After being calcined at high temperature, the fine sand will gradually dissolve and become a viscous substance like molten iron! The next step is the most critical, and it is also the place with the highest gold content. You have to look carefully !"

Yang Tiexin immediately widened his eyes.

After a period of high-temperature calcination, the fine sand really dissolved into a liquid state as Lin Yun said.

However, Lin Yun did not take out the liquid solution immediately, but continued to calcine.

Yang Tiexin asked: "Young Master Lin, what are you going to do next? What do you mean by glass?"

He had no concept of glass in his mind at all.

"The dissolved matter in this crucible needs to be continuously kept at a high temperature. The temperature must not be lowered. You must pay attention to the surrounding environment. Even a gust of wind may affect the next finished product!"

As he spoke, Lin Yun took another earthen basin on the workbench, which was filled with a layer of white substance.

"This is lime powder and quartz powder, which are the key materials for making glass! What you need to do next is to pour all the powder in this porcelain pot into the crucible!"

Lin Yun explained while operating.

After completing all the steps, he fastened the furnace cover again and continued the calcination.

During this period, he also added charcoal once.

Let the fire burn more vigorously.

And the whole workshop was already very stuffy, making both of them sweat profusely.

The old blacksmith was quite used to this kind of environment, except for sweating, it didn't affect him much.

Lin Yun wiped the sweat dripping from his forehead with his sleeve, and said, "From now on, it will take about two sticks of incense, and it will be considered complete!"

The old blacksmith nodded and said, "Mr. Lin, how did you master such high-precision tempering?"

He wanted to ask just now, as an old blacksmith, he knew very well what Lin Yun's operation meant.

If the manufactured glass is as good as Lin Yun said, it is definitely a brand new technology.

Lin Yun said with a smile: "You always think that I am self-taught! The doorway here is also something I have studied for a long time to master!"

Soon, when it was time for two incense sticks, Lin Yun opened the lid of the blast furnace, took out the red-hot crucible with a special bamboo tong, put it on the iron plate prepared in advance, and then changed his posture to put the liquid dissolved substance Pour it on the bluestone slab.

The crimson liquid was very viscous, and it flowed very slowly, but in the end it was spread evenly on it.

After another period of time, it finally cooled down, and an amber glass was finally made.

Lin Yun stretched out his hand to stand up the glass, and said with a smile, "Do you understand?"

Yang Tiexin nodded and said: "The degree is complicated. Although it is different from iron making, it is still understandable! Mr. Lin, can you let Xiao Lao try it himself?"

"Don't worry, let's do this for today, you always eat first! Wait until tomorrow daytime, there will be plenty of time for you to try!"
