Chapter 170: The Advent of Glass

Three days later, twenty craftsmen from the Gongyu family had made a total of three sets of movable type.

When they still wanted to make it, Qin An had a new task for them.

Qin An took the male sheep and they came to the glass workshop.

"Sir, are you going to teach us how to make glass?" The ram said with a little excitement.

Qin An bowed his head and said, "Not bad." In the past three days, I also tried glass refining for the first time, and found that the theory taught in the book was true, and the sand and quartz sand melted together can refine glass.

After a short firing at high temperatures, the glass becomes very soft, then shaped, and finally cooled, and a piece of art raw glass is made.

Now, I'm going to make a drinking glass, you see. ”

Immediately, Qin An threw the mixed materials into the furnace, and the fire in the furnace at this time was much cooler than the temperature of the fire in the iron-making room.

If there is an instrument test, it will definitely shock everyone present, and the high temperature of more than 1,000 degrees can be used to make iron.

Soon, the mixture was refined, forming a glass liquid, but at this time the glass liquid was in a state of high temperature.

It is then imported into a defined container and extruded to form a preliminary shape, and then processed by a hot burst or cold cut.

The next step is to pass the extruded glass through a large and long iron box, where the temperature is gradually lowered to remove the stress from the glass.

Qin An said as he did it: "The purpose of my doing this is because the glass has been in a high temperature state during processing, and if this treatment is not carried out, the glass is very easy to self-detonate at room temperature or break in use."

When I was a child, I didn't understand this, and I used to use hot hot water to pour the glass quilt all over at once, causing the glass to shatter directly.

If it is broken, we will be busy in vain, and we need to re-fire, wasting time.

In addition, glass can be fired repeatedly, and even if it is broken, it will still turn into glass water when thrown into the furnace, so when glass is available, we can recycle useless glasses and re-fire them. ”

The male sheep and the others nodded slightly, and they knew that glass had a property that could be reused.

It didn't take long for a crystal clear glass to appear in the eyes of the ram and the others.

"Oh my God." The male loser said in shock, "Crystal clear, ingenious, ingenious." ”

Gong Yi said without blinking: "Miracle, it is really a miracle, once this glass is released, it will definitely make people all over the world rush to buy it." ”

Others came to talk about it.

Qin An continued to inspect the glass, and it was only completely completed after passing the manual inspection.

Qin An took the finished glass and said, "This is the method of making glasses, this is a simple method of making glasses, you can make all kinds of glass making methods."

Even if it is for you to practice, there are a lot of materials here, and it doesn't cost a lot of money, you can practice boldly.

There are many ways to make glass, such as blowing, drawing, pressing, free forming, calendering, casting, centrifugal casting, and sintering.

I'll do it for you one by one now, and you can learn as much as you can. ”

Then Qin An demonstrated them one by one, and finally made a glass white swan and a few pieces of flat glass.

Looking at Qin An's superb income, the male losers seriously suspected that this was not the first time Qin An had made glass, but a very skilled craftsman.

Qin An didn't know what they thought, even if he knew what they thought, he could only express helplessness, this may be talent, he has been very talented in handicraft and physics since he was a child.

After the glass was completely cooled, Qin An said: "Okay, I'll leave it to you here, you can practice your hands well, whoever knows, start taking apprentices, I hope that at least five hundred people in the village will be able to make glass." ”

"No."

The male loses the sheep and others answered.

Qin An went to the courtyard with glasses and other things.

At this time, Yingzheng and they are arranging movable type printing, and they have been discussing this matter for the past few days, movable type printing is too important for Daqin, and with it, the entire culture of Daqin will change dramatically.

It is very difficult to implement the same text as the book required by Ying Zheng, but with this movable type printing, it is very simple.

All the books on the market use Qin seal, but you use Chu Wen, in this way, you will be out of place with everyone, and after a long time, even if you are a literary master, a doctor like Chun Yuyue will be inferior to others in the end.

In the end, Yingzheng decided to collect books from all over the world, which were printed and sold by the imperial court, and the price was even cheaper, and the people could afford to buy them.

In order to prevent others from hoarding, the price of books cannot be changed at will.

Just when they were about to finalize, Qin An came back, and when he saw the glass, glass water cup and glass products in his hand, his eyes lit up.

Hu Hai quickly ran to Qin An and said, "What kind of treasure is this, sir?" ”

Qin An smiled: "This is a treasure, but it is worthless." ”

"What do you mean?" Hu Hai asked puzzledly: "How can the baby not be valuable?" ”

Qin An smiled, ignored Hu Hai, but walked in front of Yingzheng and them, and put all the glass products on the stone table.

"The village chief, this is the glass. This is a glass, this is a glass craft, and I made it into a white swan.

I left the glass, and I gave this white swan to the village chief. Qin An explained while sending the glass swan to Ying Zheng.

Hu Hai pointed to the square glass on the table and asked, "Then what is this?" ”

"Glass, this kind of square glass, we call it glass." Qin An explained, "The glass that has developed in this way is exactly what I use to make glass.

Wait a minute, I'll make a window out of these pieces of glass now. ”

Immediately, Qin An took out the windows and tools that had been prepared a long time ago, installed the glass on the window, then sealed the surroundings with cement, and finally installed it on the window, and a brand new glass window was completed.

Meng Yi said in shock: "Sir, how much does this glass window cost?" ”

"It doesn't cost much, plus labor costs, according to your algorithm. Dozens of texts. The main thing is that this glass is cheaper. It's all made of sand. Qin An said.

"Impossible." Hu Hai denied on the spot, "Sand can be found everywhere, you can get countless sand without spending a penny, how can such a thing that no one wants, how can it be possible to make such a delicate thing." ”

Qin An smiled: "So this is a treasure, but it is not valuable." ”

"This ......" Hu Hai was speechless for a moment.

Ying Zheng and the others immediately understood what Qin An meant, because glass had never appeared, so it was precious, because he made it cheap, so it was worthless.
