Zhu Cixuan scratched his head a little. Which part was wrong?

Why do those travelers often use their gold fingers to make cheats? Some are said to have made the Gatlin, who is so angry that they are flying in the blue fire, and some even bombard the enemy countries with planes and aircraft carriers.

Why is everything so difficult when I get to my own place? Not to mention that it took a lot of effort to build a wooden tower crane, two of the flowering bullets I made were dull. The one I finally threw at Huang Taiji was still delayed in the explosion.

If it weren't for Fan Wencai's mentally retarded person who had never seen the world and had to pick him up and let Huang Taiji see him, then Huang Taiji would not have been injured by the bomb.

Now that I have returned to the capital, I finally found a way to make a fortune. I wanted to build a glass factory to make a fortune, but the result is that the things I made are completely different. Not only is it ugly, it is useless except for making some gadgets.

This is far from the optical glasses such as magnifying glasses, telescopes, and even reading glasses. Alas, no wonder my grandfather refused to invest, Zhu Cilang felt that he was indeed a bit hasty.

But in the eyes of others, Zhu Cilang made these things stunned them. Especially Meng Fanchao and Sun Wangcai, they all saw the eighth miracle of mankind. Why did these sands, some alkali powder and lime, become this kind of glass after being burned?

"Mr. Zhu, do you think these things will work like this?" Manager Meng didn't know what the recipe was, and he didn't think it was very strange. He thought that Mr. Zhu wanted something like this.

"Crafting, this thing is really amazing. Qian, Mr. Zhu, don't you? We have done it, and we have done it." Sun Wangcai was overjoyed.

Zhu Cilang glared at him fiercely, scaring Sun Wangcai to hurriedly put away his smile. It seemed that something was wrong.

Sure enough, Zhu Cilang sighed: "It's a slight mistake to make a thousand miles apart. Although it looks a bit like it, it's still a lot different from what I think."

As soon as this statement was spoken, Manager Meng felt a little embarrassed; "I think it was because the villain had mishandled the fire, but fortunately there were still many of these things left. Why not, the villain did it again, and maybe it would be as good as the young master's wishes."

Zhu Cilang was stunned, and then thought that maybe it was because Manager Meng was in a bad mood. Maybe it would be fine if he tried again. He nodded: "Well, Meng Fanchao, you are here to find a magnet. Suck out the iron powder in the sand. These things are too colored."

The iron in quartz sand will make the glass look greener, and after extracting the iron, the color will look much better. Magnets were not a rare thing in the Ming Dynasty. Magnets were a mineral and a Chinese medicinal material. In ancient times, natural magnets were used as medicinal stones.

Magnet, Manager Meng of the Blacksmith Shop said: "Young Master Zhu is here, I have some magnets here, so there are no need for my brother to look for them."

Manager Meng went to the inner room to rummage the boxes and cabinets, and soon he brought a magnet. Everyone carefully removed the quartz sand in the glass raw material and used the magnet to remove the iron impurities inside. Then, they poured the raw powder back into the crucible.

This time, the fire was ignited again. I followed the previous steps, but this time, the shopkeeper Meng slightly extended the temperature and heat time.

The glass made again was poured into the iron plate again, and this time it cooled down with the temperature. Sure enough, it was different from the original green glass. At this time, the glass appeared transparent color, as if it was like the ice in the winter water tank.

So much so that Sun Wangcai actually wanted to reach out and touch it, and wanted to put it in his mouth and taste it. Will it be as cold and crisp as ice cubes?

However, the same situation occurs again, there are still bubbles inside, and there are many bubbles. Not to mention that these bubbles affect the beauty of the glass, it is definitely not suitable for making telescope magnifying glasses.

Elimination of bubbles during glass melting is a big problem. Mechanical stirring is used during glass melting to help eliminate bubbles. Clarification agents are added during melting, such as antimony trioxide. Refractory powder with too fine raw material particles are likely to produce a large number of tiny bubbles, but too large the particle size will cause difficulties in melting. For example, if the aluminum trioxide particles are too large and have not been melted, stones will be produced.

It would be fine if you add clarifiers like antimony trioxide, and Zhu Cixuan would not do it. He looked at the bubbles and asked in a discouragement: "Shopkeeper Meng, how can the bubbles in the glass be eliminated?"

Manager Meng was stunned. He also saw these strange transparent glasses. The only drawback was that there were these bubbles that were difficult to melt. However, he seemed to know this: "Young Master Zhu, there are some impurities in the first smelting. This is the same as smelting iron. Doesn't it mean that Mr. Zhu doesn't want to go back to the furnace again?"

Zhu Cixuan was stunned: "You mean, put the glass back into the stove?"

"The villain thought Mr. Zhu knew that this little guy didn't understand, but when the ironware was melted again, the quality would be much higher."

Zhu Cilang was overjoyed: "Yes, why didn't I expect it. It must be true. I will re-enter the furnace. Yes, Manager Meng, can I burn it again?"

Manager Meng didn't say anything, picked up the hammer and smashed the glass with a bang, and then put the broken glass into the crucible again. This time, it was back to the furnace again.

However, the second time the glass calcined was poured into the iron plate, there were no more bubbles. Until it turned cold and formed, a piece of square and clean transparent glass lay quietly in the mold of the iron plate.

Everyone held their breath. Zhu Cixuan carefully took out the remaining warm glass from the iron plate. In this way, the square glass product, the size of a palm, was successfully made.

Everyone opened their eyes wide in surprise. What a magical thing. This thing is so transparent. If it is used to be embedded in the window, it will be like spring in winter. The world outside the window is clean and bright.

In Zhu Cilang's eyes, this small piece of glass was filled with piles of white silver. He knew what it would mean once these glasses were used in business.

This will mean the birth of a monopoly and profit-making industry. No one in the entire Ming Dynasty could understand this production process. Moreover, glass raw materials are very easy to obtain and are cheap.

Zhu Cixuan took the glass and showed it joyfully on his face: "Hahaha, it's done, Meng Wei, Wangcai, we've made it! Hahaha, good things, really good things."

Meng Fanchao nodded hurriedly: "Now the master of the country will be happy to see him."
