Zhu Cixuan walked into the blacksmith shop. The shopkeeper Meng of the blacksmith shop saw his brother walking in with a luxurious man, and hurriedly stopped the hammer in his hand: "Brother, I am very dirty here, what are you doing here?"

Meng Fanchao hurriedly stepped forward and recommended: "Brother, this is Mr. Zhu. Thinking of making something in your blacksmith shop, you should stop the work in your hand first. This is Mr. Zhu who rewards you."

This is a travel in a condom. Zhu Cilang didn't want to reveal his identity to avoid unnecessary trouble. But Manager Meng also vaguely guessed that this young master named Zhu, and it was brought by his brother. The other party naturally has a prominent identity, either a certain prince or a royal relative.

If it were a prince, it would be amazing, and the royal relatives would be just as good as that. Since Zhu Yuanzhang established the country, the old Zhu family has grown up. During the Wanli period, the genealogy recorded that the members of the royal family were more than 150,000, and the lowest at the end of the year should be more than 200,000.

So many royal relatives are worthless. But his brothers are on duty in the palace and are respectful to this young man. Then Manager Meng inferred that Zhu Cilang's status would never be very low. At least, he must be a prince or something.

Meng Fanchao was generous and gave his brother two taels of silver. This made Zhu Cilang more noble. Manager Meng hurriedly said respectfully: "Young master, but he has given me the order, and the villain should do his best."

Silver is a hard currency among hard currency. During the Chongzhen period of the Ming Dynasty, the annual treasury income was only four million taels. It was a bit exaggerating to say a few dozen or hundreds taels, and even more exaggerated rewards of millions and tens of millions of taels.

In addition to the Song Dynasty, the Song Dynasty was the richest dynasty, with taxes reaching over 100 million a year. Unfortunately, the country was later destroyed by the Yuan Dynasty. By the Ming Dynasty, the tax revenue was not bad in the middle of the Ming Dynasty, especially during the Chongzhen period, the national treasury began to shrink significantly.

Zhu Cilang nodded: "Shopkeeper Meng, Ben, I brought some things here. You put them in the furnace and burn them for me. Just like you smelting iron, it can be turned into molten iron."

In fact, the technology of glass manufacturing is relatively simple, and it only requires a certain technical content to make large pieces of glass. Just making small objects requires melting the raw materials and cooling them out, and then it becomes glass.

Meng Fanchao handed the quartz sand, soda ash and limestone he got to his brother. Manager Meng looked at the things in the cloth bag, and he was stunned after opening it: "What is this?"

"Brother, don't care what it is. Put it in the stove and calcinate it vigorously." Meng Fanchao handed him the cloth bag, but in fact he had no idea. Can this thing make glass similar to transparent crystals?

In fact, Zhu Cilang was not sure, but everything was difficult at the beginning, so he had to try it. Theoretically, it was not difficult to make a simple glass. After all, this thing can be crystallized by just burning it.

Crucibles were already popular in the Ming Dynasty. The blacksmith shop used a crucible to put it in a charcoal furnace and kept calcining it, and the iron in the crucible would melt. Then pour out the iron with pliers, and then repeatedly forge it to become the best iron tool.

Put the glass mixture into a heat-resistant crucible, which should withstand extremely high temperatures in the kiln. The melting point of the glass is relatively low, and the crucible container should be easily controlled by metal hooks and rods.

Meng Fanchao found a chair, wiped it with his sleeve and moved it carefully to Zhu Cixuan. Zhu Cixuan sat down without hesitation, and according to Zhu Cixuan's instructions, everyone quickly began the calcination process. This was familiar to Manager Meng. He poured the raw materials into the crucible and put them into the charcoal furnace.

The red charcoal burned the furnace heat. The child pulled the bellows hard, and soon the temperature in the furnace rose. Zhu Cixuan wanted to go forward and take a look, but a wave of heat coming to his face made him retreat in a daze.

Strangely, Manager Meng seemed not afraid of heat. He was shirtless and his bronze skin was even brighter under the charcoal fire. He seemed to be patellated. These were pure physical work. Perhaps because he received a huge reward, Manager Meng pulled the child up and pulled the bellows himself.

I don’t know how long it took, and the mixed raw materials and the crucible were burned red. It seems that they were done.

Zhu Cilang stood up in a daze: "Okay, pour out the things in the crucible. Manager Meng, find an iron plate and pour it into the iron plate."

Manager Meng put down the bellows, stood up and looked at the crucible in the stove: "Young Master Zhu, I'm afraid it won't work, let the villain burn for a while."

The calcination process and the temperature of Zhu Cixuan naturally knows much more than Zhu Cixuan. He said no, it must not work. Zhu Cixuan didn't say anything, and returned to his position.

After a while, Manager Meng got up and looked at it a few times. Finally, he picked up the iron tongs and clamped the crucible in the furnace. In the red crucible, there was the forged glass solution.

The child found a smooth iron plate with grooves. Manager Meng asked hesitantly: "Young Master Zhu, do you pour it in like this? Do you need to forge it?"

Zhu Cilang said with some conscience: "Pour it in, it's glass, no need to be forged."

The glass juice was poured into the iron plate, and Zhu Cixuan stood up again, and Meng Fanchao and others couldn't help but come forward. The raw materials in the crucible had turned into juice. After pouring into the iron plate, they finally began to cool down slowly.

The juice cooled on the iron plate finally showed its true colors of glass. The dead eunuch Sun Wangcai couldn't help but shout: "It's done, thousands of years, thousands of tempers, Mr. Zhu, it's finally done!"

This sentence was inappropriate. He wanted to call Mr. Qiansui. Fortunately, he responded in time and changed his words in a hurry. Otherwise, Zhu Cixuan's identity would have been exposed, and the glass inside the iron plate cooled down and finally became crystals.

However, Zhu Cilang was very disappointed when he saw it. This was different from what he imagined.

First of all, the color is wrong. Although the glass is also transparent, the color of the glass itself is a bit green. This is because the iron impurities in the quartz sand are made of green. However, the green color is not a big deal. Next time, you only need to remove the iron in the quartz sand with iron-absorbing stone, which will make the green light or even transparent.

This did not have any big impact. What Zhu Cilang couldn't accept was that the glass was full of bubbles and there was no transparency at all. At best, it was just an ugly piece of glass bump.

This is what I imagined. A piece of smooth and clean, transparent glass is completely different. This kind of thing can be used to make some small handicrafts and inlaid windows. It is probably extremely ugly.
