Chapter 170 The advent of glass
Three days later, twenty craftsmen from the Gongshu family produced 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 brought Gong Shuyang and the others to the glass workshop.
"Sir, are you going to teach us how to make glass?" Gong Shuyang said slightly excitedly.
Qin An nodded and said, "That's right. In the past three days, I also tried refining glass for the first time, and found that the theory taught in the book is true. Glass can be extracted by melting sand and quartz sand together.
After short-firing at high temperature, the glass will become very soft, then shaped, and finally cooled, and a piece of artistic raw glass is ready.
Now, I'm going to make a water cup. Take a look. "
Immediately, Qin An threw the mixed materials into the furnace. At this time, the fire in the furnace was much lower than the fire in the ironmaking room.
If there is an instrument test, everyone present will be shocked. High temperatures of more than 1,000 degrees can be used to make iron.
Soon, the mixture was refined and a glass liquid was formed, but the glass liquid was at a high temperature at this time.
Then watch it be introduced into a designated container and extruded to form a preliminary shape, and then undergo mouth processing such as hot blasting or cold cutting.
Next, the extruded glass cup passes through a large and long iron box. The temperature inside gradually decreases to remove the stress of the glass cup.
Qin An said while doing it: "The purpose of this is because the glass is always at a high temperature during processing. If this treatment is not carried out, the glass will easily explode at room temperature or break during use.
When I was a child, I didn't understand this. I once filled the glass quilt with boiling hot water, causing the glass to break.
If it breaks, our work will be in vain and we need to re-fire it, which is a waste of time.
Also, glass can be fired repeatedly. Even if it is broken, it will still turn into glass water when thrown into the furnace. Therefore, when glass becomes available in the future, we can recycle useless glasses and re-fire them. "
Gong Shuyang and others nodded slightly. They also learned about another characteristic of glass, which is that it can be reused.
Not long after, a crystal clear glass appeared in the eyes of Gong Shuyang and others.
"Where's the sky?" Gong Shuyang said in shock, "It's crystal clear and ingenious. It's ingenious."
Gongshu Bai said without blinking: "A miracle, it is truly a miracle. Once this glass comes out, people all over the world will flock to buy it."
Others came to discuss it one after another.
Qin An continued to inspect the glass, and it was only completely completed after it passed manual inspection.
Qin An held the finished glass and said: "This is how to make a glass. This is a simple way to make a glass. You can make it into a variety of glass making methods.
It's just for you to practice. There are a lot of materials here and you don't need to spend a lot of money. You can practice boldly.
There are many methods for making glass, including blowing, drawing, pressing, free forming, calendering, casting, centrifugal casting, and sintering.
I will do it for you one by one now. You should pay attention and learn as much as you can. "
Qin An then demonstrated one by one, and finally made a glass white swan and several pieces of flat glass.
Looking at Qin An's superb profits, Gongshu Yang and others seriously doubted that this was not Qin An's first time making glass, but he was a very skilled craftsman.
Qin An didn't know what they were thinking, and even if he knew what they were thinking, he could only express helplessness. This might be talent. He was very talented in crafts and physics since he was a child.
After the glass was completely cooled, Qin An said: "Okay, I'll leave this to you. Practice your skills. Whoever knows how to do it will start taking apprentices. I hope that at least 500 people in the village can make glass."
"promise."
Gong Shuyang and others responded.
Qin An went to the yard with glasses and other items.
At this time, Ying Zheng and the others are arranging for movable type printing. They have been discussing this matter for the past few days. Movable type printing is so important to Great Qin. With it, the entire culture of Great Qin will undergo earth-shaking changes.
It was very difficult to implement the same text as required by Ying Zheng, but with this movable type printing, it was very simple.
All the books on the market use Qin seal script, but you use Chu script. If you do this, you will be out of tune with everyone. Over time, even if you are a literary master, you will end up with a Ph.D. like Chun Yuyue, not as good as others. people.
In the end, Ying Zheng decided to collect books from all over the world and have them printed and sold by the imperial court. The prices were even cheaper and the common people could afford them.
In order to prevent others from hoarding, the prices of books cannot be changed at will.
Just when they were about to finalize the decision, Qin An came back. When he saw the glass, glass water glass and glass products in his hand, his eyes suddenly lit up.
Hu Hai quickly ran to Qin An and said, "Sir, what kind of treasure is this?"
Qin An smiled and said: "This is a treasure, but it is worthless."
"What do you mean?" Hu Hai asked in confusion: "How can the baby be worthless?"
Qin An smiled and ignored Hu Hai. Instead, he walked up to Ying Zheng and the others and placed all the glass products on the stone table.
"Village Chief, this is glass. This is a glass cup, this is a glass craft, I made it into a white swan.
I keep the glass, and give this white swan to the village chief. " Qin An explained while delivering the glass swan to Ying Zheng.
Hu Hai pointed to the square glass above the table and asked, "Then what is this?"
"Glass, we call this square glass glass." Qin An explained, "The glass developed in this way is what I use to make glass.
Please wait a moment, I will use these pieces of glass to make a window now. "
Immediately, Qin An took out the window and tools that had been prepared long ago, installed the glass on the window, then sealed the surrounding area 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 the labor cost, according to your calculation. It's about a few dozen yuan. The main reason is that the glass is cheap. It's all made of sand." Qin An said.
"Impossible." Hu Hai denied it on the spot. "Sand can be found everywhere. You can get countless amounts of sand without spending a penny. How can you make something so exquisite when no one wants it?"
Qin An smiled and said: "So this is a treasure, but it is not valuable."
"This..." Hu Hai was speechless.
Ying Zheng and others immediately understood what Qin An meant. Because glass has never appeared before, it is precious, and because he made it cheaply, it is worthless.
