The tyrant of the Great Zhou Dynasty starts by summoning a fierce general!

In fact, the most difficult part of firing glass is how to increase the temperature, and once this point is broken, the rest of the matter is much simpler.

Gao Shun held a special iron tong and put it into the crucible furnace.

Then Lu Yao gave an order, and Niu Shan threw off his arms and pulled the bellows frantically.

A large amount of oxygen pours into the crucible furnace, and the temperature inside the furnace gradually rises.

The sand located in the center also began to melt.

After a while, the sand turned into a glass solution of red liquid fluid.

However, it is not possible to take out the glass solution at present, because there are still many impurities in the glass solution at present.

If it is not removed in time and cooled down, the glass will not only become colorful, but also have a lot of small bubbles.

It not only affects aesthetics, but also practicality.

At Lu Yao's suggestion, Gao Shun picked up the iron skewer and began to stir the glazed solution in the furnace.

As the stirring progressed, a lot of white mist appeared directly above the glass solution, and the impurities contained in it were evaporated.

If you want to make transparent glass, you need to mix it many times and mix it with the right ingredients.

This is a big project, and Rao is Niushan can't stand Lu Yao so much if he has the strength to do so.

Half an hour later, Niu Shan lay on the ground, panting heavily.

It was as if he had just been fished out of the water, and his body turned red under the rays of the sun and the boiling heat of the crucible furnace, like a roasted cow that had been cooked.

At this moment, Niu Shan only felt that his two arms and shoulders no longer belonged to him, which was even more torturous than torture.

Gao Shun was also uncomfortable at the moment, his face was as red as a monkey's ass from the heat wave.

Finally, after an hour, Lu Yao announced in a high-profile manner that it was time to start the furnace.

The glass that has just come out of the pot has strong ductility when it has not completely cooled, and at this time, the glass can be shaped by blowing air through a hollow iron pipe.

But at the moment, Lu Yao is just doing experiments, so naturally he doesn't care about the problem of modeling.

Cut off some of the red-hot glass and set it aside to cool, and everyone's eyes were attracted to this thing at the moment.

Wang Yong is also a well-informed person, and he has also heard of the glass thing.

"When the old minister was young, he also saw the glazed products from foreign countries in the treasury of the first emperor, and this glance alone made the old man forget for many years, and it is said that this thing is unique to foreign countries and is very precious. Obviously

, Wang Yong didn't believe that this precious glass could be made of the most common and ordinary sand.

Lu Yao replied while observing.

"Actually, the principle of making many things is very simple, as long as you master the method.

Niu Shan rubbed his shoulders and asked suspiciously.

"Your Majesty, this thing is the legendary glaze, why don't I look like it?"

Lu Yao didn't explain, after all, facts speak louder than words.

As the temperature gradually drops, the red glass solution begins to solidify.

The original red color slowly changed to transparent white.

"It's changed,

it's changed, it's changed!" Niu

Shan jumped up from the spot as if he had seen some miracle, and he didn't know how to describe it in words.

He just patted Gao Shun's shoulder and pointed to the glass that was cooling.

Gao Shun was also a little impatient by him, and said coldly with a red-hot face.

"I can see without being blind under my eyes.

Lu Yao clamped the cooled glass with special iron tongs, and the glass shone in the sunlight.

Wang Yong's eyes widened, and his mouth was shocked into a big 'O'.

Wang Meng on the side also frowned and fell into deep thought.

"It's obviously sand, but why has it become such a beautiful glass now?Strange! It's so strange!"

Obviously, Lu Yao's operation touched his blind spot in knowledge.

Lu Yao looked at the puzzled expression on Wang Meng's face, and was quite happy in his heart.

It is a very rewarding thing to let this kind of top world fall into self-awareness and doubt.

After a brief moment of excitement, Lu Yao began to carefully observe the glass that had been fired for the first time.

The piece of glass in his hand is obviously very different from the glass in Lu Yao's impression in later generations.

The color is not transparent, and there are a lot of variegated colors, and there are a lot of bubbles inside the glass.

There is still a long way to go to meet the requirements of telescope lenses.

"Ding Dong! Congratulations to the host for achieving the achievement 'Fired Glass' Reward Prestige: 300 points, remaining prestige points: 4005 points. When

I heard the sound of the system, the original sense of disappointment disappeared.

After all, nothing can be done casually, and if you want to achieve a certain requirement, you must experience a thousand failures.

Failure is the mother of success, and Lu Yao threw the glass back into the crucible furnace.

Wang Yong who watched this scene was very distressed, you must know that this is a genuine glass, a more expensive existence than gold.

At present, it is being rebuilt by Lu Yao like garbage.

After doing all this, Lu Yao turned his head to Wang Yong and said.

"Prime Minister Wang. "

The minister is here. "

Have you memorized this method of refining glass?" Wang

Yong was stunned when he heard this, and then said in a panic.

"Remember some ......"

Wang Yong was apprehensive at this time, after all, the value of creating glass can be imagined, and this kind of secret that is not passed on is naturally better than one less person to know.

As soon as he thought of this, Wang Yong's legs were weak and he knelt directly on the ground, and said in a panic.

"The old minister will never dare to leak a word to the outside world! Please spare your majesty's life!"

Lu Yao: ......

Lu Yao patted his head, Wang Yong, how could this guy be so good at making up for his own brain, and he could only say helplessly when he saw this.

"Prime Minister Wang get up quickly, when am I going to kill you?"

Wang Yong was stunned.

"Then I don't know why Your Majesty asked Lao Chen if he had memorized the refining method?"

Lu Yao cleared his throat and explained.

"The matter of refining colorless transparent glass is very important to me, and it is related to the development of the Great Zhou Society, so I naturally have a heavy responsibility to call you here today.

Wang Yong's expression was stunned when he heard this, as if he had thought of something.

Since Lu Yao had famous generals like Fan Lihua and Wang Meng by his side, Wang Yong has become more and more transparent.

Don't look at him in a high position, but he has nothing to do all day long, and he lives quite a tormented every day, for fear that he will be abandoned by Lu Yao one day.

Lu Yao leaned over and helped Wang Yong up from the ground, as an old man who had been by his side from the beginning, Lu Yao was naturally quite grateful to Wang Yong, after all, it was this white-haired old man who was by his side when he was most frightened.

Lu Yao looked at Wang Yong, who was wrinkled in front of him, and said.

"Prime Minister Wang, you are the person I trust, today I will hand over to you the important matter of refining colorless transparent glass, this matter is related to the Great Wednesday Hundred Years of Jiangshan Sheji, and please Prime Minister Wang Cheng do not let me down.

Wang Yong's heart was shocked when he heard this, it turned out that Lu Yao had not forgotten him from beginning to end.

Lu Yao spoke again.

"No matter where I am, I will always be the Lu Yao who was protected by you in the broken temple.

As soon as these words came out, Wang Yong couldn't hold back anymore, tears burst out of his eyes, and

all the panic and uneasiness at this moment disappeared.

Even if there are thousands of words, they are only gathered into one sentence at this moment.

"Even if you are poor, you will be the first to be poor! The old minister will definitely live up to His Majesty's trust!"
