"I just speculated that it would work. Mr. Liu felt a little sure, so I'll give it a try!" Zhao Qi stood beside him and nodded softly.

"It's okay to try it. You can change the stove quickly, but we can't sell it even if it's tested. If the Lu family finds out, they may cause trouble!" Yang Dahu looked at Zhao Qi with some concern.

"We are just experimenting. If we succeed, we will hide the technology first and not do it for the time being. The Lu family can't say that we broke the contract. Moreover, even if we do it now and sell it, the Lu family can only pinch their nose and suffer a loss. They dare not jump around recently. Lu Guangping heard that he was still locked in the police station and was not released back!" Zhao Qi said with a smile.

"Yes, the dog-good Lu Guangping actually dares to kidnap you and wants to occupy A Lian. Such people have no morals to talk about. Since Xiaoqi and Uncle Qi both said it would work, let's try it first. Whether glass is sold or not is another matter. The construction site is too busy at the moment, and there is no time to make glass. Where can I make money by repairing the harbor..."

Yang Dahu wiped the sweat off his face with a dirty rag hanging on the railing of the awning, and asked his apprentice to prepare the fire bricks and mud to prepare for the remodeling of the stove.

"Actually, I didn't plan to rush to test the method of making glass, but because Duke Chong came to the construction site to inspect and suppress the Lu family's arrogance, he helped us a lot. Otherwise, it would be a question whether the harbor could be repaired. In order to thank him, I want to make some exquisite and beautiful glass for Duke Chong as a thank-you gift, because now we have no gifts to give except for earning a lot of money, including silk brocade, gold, silver and jade. Duke Chong is not short of. Even if he spends a lot of money to buy and send it, it seems a bit vulgar..." Zhao Qi sat down to explain.

"Da Yuan and I were discussing with Manager Liu this morning, should we come to you to prepare some gifts tomorrow to go to the city. I didn't expect that you would be more thoughtful than we thought. You really have to give gifts, which are expensive and special. If you can really make some beautiful, exquisite and unique glass, I think Duke Chong will definitely like it. If you can enter Duke Chong's house, many people will be squeezed out of their heads!" Yang Dahu nodded and said.

"Since Uncle Dahu thinks it can work, then let's do a few things this time. Today we will try it first. As long as the method is successful, we will find someone to get some purer crystal stones tomorrow and make more selected ones to send!"

"Xiaoqi, do you mean that glass is made of crystal?" Yang Dahu only realized this time.

"Well, I picked up some dirty crystals that I didn't want in jewelry stores last time. When I was playing with it, I found that they were actually very similar to glass. They were both transparent and hard and easy to break. So I thought about whether I could make glass with crystals. Although crystals are expensive, they are far less expensive than glass. With just a little processing, they can make a few dozen times the profit. It is not necessarily worse than repairing the wharf. However, it is definitely troublesome to do it well and it requires long-term burning and accumulated experience."

"This Brother Qi is right. All industries are a process of practice making perfect. The same is true for us to make porcelain. A good craftsman's salary is more than a county magistrate gets in a year!" Old Man Liu nodded beside him and agreed.

"Uncle Dahu, Grandpa Liu, I agree that if the experiment is successful this time, I can't tell you for the time being. This technique must be kept for the future and make a lot of money!" Zhao Qi lowered his voice and reminded him.

"Don't worry, as long as you don't let me say it, I will definitely rot in my stomach. I will drive away all the apprentice workers later. This time, the three of us know that Dayuan is hidden from him!" Yang Dahu quickly patted his chest and promised.

"I, old man, you are even more relieved. Maybe one day I will go there. Why did I get so much money? I was so scared when I got the money for repairing glass last time!" Old Man Liu waved his hand and said that he would not even say anything even if he died.

"Xiaolongwan Port was built very quickly and it was completed in almost a year. At that time, we can open a warehouse to freight and open a shop in the store. Glass is our way to make a fortune in the future. If the method is passed, the loss will be huge. Maybe everyone will lose dozens of millions of yuan. After the Xiaolongwan Port is repaired, we will build a glass factory, which will specialize in firing various exquisite glassware. Mr. Liu will be the technical director of our glass factory, and then build a big house with a garden for you, prepare all the carriages, horses and slaves, and marry a few young concubines..."

"The more you talk, the less you lose. My old man is almost buried. It's okay to live in a carriage in a big house, but why should you marry a young man?" Old man Liu interrupted Zhao Qi's words with laughter and cry.

"Master Liu, you are only sixty years old, so you are old no matter where you are. Duke Chong is already sixty-five years old this year. Last time I went to the capital city to see him blush and in good spirits. Now the seventh lady is taking care of you. You have a much better cough recently. There is no problem in living at 80 in the future!"

"Haha, Uncle Qi married a young man, and then our entire village will celebrate and have a drink!" Yang Dahu laughed.

"I like drinking the most, and I have to re-cook the meat!" Old Man Liu also smiled so hard that he couldn't stop smiling.

The three of them laughed and chatted and joked. Soon seven or eight minutes passed, and all the fire bricks and mud used to change the stove were prepared. Yang Dahu walked into the blacksmith shop, ordered to carry water and mud, and picked up the mud knife to start the transformation of the coal stove.

Twenty minutes passed, and this time I was familiar with the road and quickly changed the stove. After all the messy things on the ground were cleaned up, Yang Dahu rushed several apprentice workers to the outside of the yard and refused to come in. Then he closed the door of the blacksmith shop and asked, "Xiaoqi, what should I do now?"

"The method is still the same as last time, but it is to replace the broken glass with pounded crystal stones!" Zhao Qi said, picking a few crystal stones about the same color from the back basket, throwing them into an iron mortar and pounding them into fine sand. After pounding, he grabbed a handful and handed them to Master Liu and Yang Dahu and said, "Look, is this very similar to broken glass?"

"It's true, it's very similar. Brother Qi, you just like to think about it, we have never thought about it!"

Yang Dahu and Old Man Liu nodded in agreement.

The next step is simple. The steps are exactly the same as melting broken glass. Put crystal sand into the crucible, then close the furnace door and pull the bellows to burn the fire. The red flames in the whirring sound sprayed out more than one foot from the bottom of the crucible, and then were blocked by the furnace wall. Then, like a volcano, the entire crucible was wrapped in red and hot flames. The strong heat sprayed out from the cracks of bricks and stones. In an instant, the temperature of the whole room rose by more than ten degrees. Sweat came out from the foreheads of three people like mud, and the clothes were sweating instantly.

"Xiaoqi, is it almost done?"

After half an hour of pulling in one breath, the flames in the furnace had become blazing and dazzling. Yang Dahu, whose arms were thick as an engine, could no longer support him. The sweat all over his body wet the ground.

"Let me see!" Zhao Qi used iron pliers to clamp the fire bricks at the opening of the furnace and looked inside. He found that the crystal sand in the dry pot had turned red, but there was no sign of melting. Therefore, he quickly blocked the furnace and shook his head and said, "It's not enough, it's far from it. I'm afraid that this pot will be boiled for more than half an hour!"

Yang Dahu had no choice but to continue pulling the bellows. Mr. Liu was responsible for looking at the coal in the stove. When he found that the firepower had begun to drop, he cleaned the stove and went inside.

More than ten minutes passed, and Yang Dahu couldn't hold on anymore. Zhao Qi raised his head, but it took less than ten minutes to yell. Yang Dahu had to call a helper who was kicking out of the yard to help. Hulala another half an hour passed. Until the helper was sweating and shouting that he couldn't do it, Zhao Qi saw that the crystal sand in the crucible had begun to melt.

"It's so fast, it's melted, it's almost done in another half a moment!" Zhao Qi reminded with an excited face.

"You go out!" Yang Dahu pointed outside the door, and the helper quickly ran out with a rush, sweating all over his body as if it was fished out of water.

"Tell me quickly, what are the master and Brother Qi doing inside? It's so mysterious?" A group of apprentices and helpers gathered to inquire.

"I don't know, I just pulled the bellows when I went in. I didn't know anything inside, but it was definitely not an ordinary object. It's been almost an hour since such a big fire..." The helper sat under the shade of the tree and gasped.

In the blacksmith shop where the fire was burning, Yang Dahu carefully clamped the crucible with large iron tongs and placed it on the ground. Half of the pot of melted red and white melt was still rolling and bubbled, as dazzling as the boiling magma in a volcanic pit. Under the high temperature, the mud and sand debris on the ground were ignited.

"Haha, it's really melted. It seems that Xiaoqi's inference must be good. Unfortunately, there is not enough manpower to make a few sand turning molds, otherwise you can cast a few utensils to see." Yang Dayuan shook his forehead and the sweat rolling down, so excited that he couldn't stop.

Old Man Liu didn't care about the high temperature baking and squatted beside the crucible, his face full of wrinkles and smiled.

If he was just inferred at the beginning, he was now convinced that Zhao Qi's method had no problem. As long as the boiled crystal stone was reshaped like the last time he repaired the glass, it would be the best glass object.

"If I had known this, I would have done the sand model first. What a pity. Once this cools down, it will take only one more time to suck it..." Old Man Liu stared at it for a while and shook his head regretfully and stood up.

"No hurry, don't use molds today. I think glass can be made using another method, maybe it's better!" Zhao Qi smiled and brought the iron pipe he brought over.

"Iron pipe?" Mr. Liu and Yang Dahu were confused.

"When I repaired the glass last time, I found that although the melted glass can be cast and shaped, it does not flow smoothly like iron and copper juice, but is a bit sticky like sugar, which is the kind used by those who blow sugar in the town. I was wondering since the sugar blowers can blow out all kinds of beautiful sugar people with sugar, then can the glass be blown into various shapes while it is hot after melting!"
