After reading it, Wang Yong nodded with satisfaction, handed the glass to Sophia and the others, and asked them to also see the so-called glass.

Wang Yong pushed open the door of the kiln and saw that the sun was already shining outside, so he asked Sophia to come out with the glass, and then watched the scene outside through the glass.

It was the first time that Sophia and the others saw this transparent, clear crystal, and they jumped and screamed happily, like a little broken child who had found a new toy.

But when Sophia was jumping around and making faces with Shamantha and Lukya through the glass, Lukya accidentally hit her head on the glass, and when she heard a bang, the glass in Sophia's hand shattered into many large and small pieces and fell to the ground.

They were caught off guard by this sudden change, Sophia stared blankly at the glass shards on the ground, looking at them at a loss, David and Shamantha were also stunned, only Lukya was still moving, he was constantly wiping the blood from the wound on his forehead.

Wang Yong was also attracted by the crisp sound of shattering glass, and when he saw that Lukeya was injured, he hurriedly ran over to check. At this time, Sophia and the others also came to their senses, and hurriedly took out water to help Lukeya clean his wounds, and saw that Lukeya's forehead was only a small wound the size of a grain of rice, and everyone was relieved.

Shamantha complained that Lukeya was careless, and at the same time gently helped him with medicine, which made Lukeya giggle.

Wang Yong picked up a piece of broken glass and looked at it, then beckoned everyone to re-enter the kiln, holding the broken glass and asked proudly: "How is it? This is the glass I am talking about, not bad?"

Sophia nodded vigorously and said, "It's good, but it's too sturdy, I don't know what it can do." ”

Wang Yong smiled and said: "This is only a semi-finished product, and it still needs a few processes to make real glass." What we have to do is tempered glass, which has high strength, good tensile and impact resistance, and is not easy to break. Even if it is broken, it will not shatter in the form of particles at acute angles, and the damage to people is greatly reduced, which can basically avoid accidents like Lukea's head and blood flow. ”

Sophia and the others were very surprised, not surprised by what Wang Yong said. Instead, he was surprised that Wang Yong could talk like a knowledgeable learner.

Wang Yong smiled proudly. Then he said, "Come, I'll make a piece of tempered glass and let you open your eyes." As he spoke, Wang Yong had already added various materials to the smelting pot according to the formula ratio of the glass, filled the smelting pot with seven or eight layers, and then began to slowly heat it with an ordinary flame.

Then. Wang Yong transformed the two spar slabs that had just pressed the glass, and made one of the spar slabs into a two-meter square square, surrounded by a border less than two centimeters higher than the plane, and some small holes in the four inner corners and frame.

The other spar slab is made into a flat letterpress, and the size of the protrusion is exactly the same as the size of the groove, so that the two spar slabs can be brought together. However, there is a flat space in the middle, which is less than two centimeters high and almost two meters square.

Next, Wang Yong drew a heated magic array on the two spar slabs before stopping and patting the non-existent dust on his hands.

Just when everyone thought that Wang Yong's preparations were complete, Wang Yong suddenly slapped his forehead, turned his head and asked Lukeya, Sophia and the others, "Will you let the temperature drop the magic array?"

Shamantha raised his hands and said, "I will, I will." ”

Wang Yong let out a sigh of relief. He said to Shamansa, "Come here." Draw a cooled magic circle on top of these two hedron tablets, keeping in mind that the cooling effect should be even. Shamantha raised her chin at Sophia and Lukia with a smug expression. Then he walked to the spar slab, and under Wang Yong's guidance, he used space magic to draw two cooling and cooling magic arrays in the spar.

During this period, Wang Yong also curiously asked Shamansa how he could use this magic array, but the answer he got made Wang Yong speechless for a while.

It turned out that Wang Yong had mentioned air conditioning to Reagan before, and Reagan felt that the climate in the seaside province was hot, and it would be very uncomfortable in the summer, so according to the role of air conditioning mentioned by Wang Yong, he researched this magic array that can reduce the temperature, and planned to wait until summer to make a magic air conditioner to cool down and escape the heat.

And when Shamansa was studying with Reagan and Rook at the time, this magic array Reagan used it as a teaching material for them to practice, so Sophia and the three of them understood this magic array.

After Shamansa drew the magic circle, the materials inside the smelting pot also just melted.

When the molten glass inside the crucible cooled down to a moldable form, Wang Yong poured the molten glass inside into the groove of the spar slab, and then covered another spar slab on it and pressed it vigorously.

Because Wang Yong was also pressing for the first time, he didn't grasp the capacity of the groove very accurately, so he poured out a lot more liquid glass, which flowed out along the small hole next to the groove.

When the edges of the two spar slabs were completely closed, Wang Yong released his divine sense to probe the situation inside. A confined space with a thickness of more than ten millimeters and a square of two or two meters was formed between the two spar slabs, and the molten glass had completely filled this space.

Wang Yong nodded with satisfaction, chatting with everyone, talking about the various paths of glass, and at the same time opening the heating magic array on the spar slab, controlling the temperature of the liquid glass inside to slowly drop.

After about half an hour, the glass inside the spar slab had cooled, and Wang Yong raised the temperature of the magic array again to warm the glass inside.

After about ten minutes, the glass inside was already showing signs of melting, Wang Yong hurriedly stopped the heating, and instead activated the refrigeration magic array engraved by Shamansa to quickly cool down the glass inside the spar slab.

While Wang Yong was busy with his own work, he explained the role of the two processes of annealing and quenching. Wang Yong only said the purpose of these two processes, and Wang Yong did not mention the professional terms of thermal stress at all, because Wang Yong himself did not understand, and he only knew a little about these professional things.

David never spoke, but concentrated on holding a pen and paper and constantly recording each process and the content of Wang Yong's explanation.

When the glass in the spar slab cooled down again, Wang Yong opened the spar slab, and everyone looked at the glass slab inside. Wang Yong touched the smooth surface of the glass, and then motioned for everyone to help, lifting the glass more than ten millimeters thick out of the spar groove and standing on its side on the ground.

Wang Yong knocked on the tempered glass with a proud face, knocked the glass 'dangdang' and asked: "How is it?" This is what I said about tempered glass, is it much stronger than the semi-finished product just now." ”

When Sophia and the others saw Wang Yong's actions, they also tried to tap on the glass, which looked clearer and more transparent than crystal, and after a crisp sound, everyone's faces showed happy smiles.

Next, Wang Yong tested the strength and impact resistance of this piece of tempered glass, and without using true qi, Wang Yong took a lot of effort to break this piece of physically quenched tempered glass.

Looking at the large and small glass fragments on the ground, everyone's expressions were different, Wang Yong's face was full of joy, and he was quite satisfied with the quality of the tempered glass, while Sophia and the others were indeed pity, complaining about Wang Yong's ruined behavior.

Regarding everyone's complaints, Wang Yong just smiled and explained that this was a normal test, and the glass would be broken and then done. In order not to waste the material, Luke Linen collected the large pieces of glass, put them back into the smelting pot, and added some more materials to heat them together.

Wang Yong did not participate in the production this time, but explained the essentials of each step and his own pitiful experience.

When Sophia and the others successfully made a piece of tempered glass of the same size, everyone was excited for a while, and David scratched his head and asked: "Boss, didn't you say that you want to use this glass to make a window?" But this glass is also too big, and it is uneven after being broken, and the windows made are not good-looking." ”

Wang Yong smiled, didn't answer, took out the diamond knocked from Kevin, smashed it with great effort, and then jumped a sharp angle of diamond fragments, and made a simple glass knife out of hedron.

Wang Yong used a glass knife to make a cut on the tempered glass, and then struck it with a wooden block, and after the glass was broken, Sophia and the others were stupid, and they didn't know what Wang Yong was going to do?

Wang Yong squatted on the ground depressed and held his head for a while, but after a while, he didn't come up with a reason.

In the end, Wang Yong decided to continue to try, everyone worked together, David was responsible for adding materials and firing liquid glass, and Wang Yong and Sophia made four sets of spar slabs of pressed glass with different thicknesses. This time, Wang Yong left two pieces of ordinary glass that were not quenched after normal annealing, and after the cutting experiment with a glass knife, it was finally concluded that the tempered glass that was quenched again could not be cut and transformed after molding, and the ordinary glass that was only annealed and not quenched could be cut into various shapes with a glass knife at will.

Wang Yong took a piece of ordinary glass that was cut into a circle of half a centimeter and said: "Although this kind of glass is not as strong as tempered glass, it is not broken when touched. Lukya also held a triangular piece of glass that he had cut with a glass knife, and chuckled as he chuckled, nodding in agreement.

In order to let everyone understand the glass window more intuitively, Wang Yong even hired a carpenter to make a wood-framed glass window on the spot to replace a wooden window in David's room.

Everyone stood in front of the glass window, looking at the scenery outside the window and the busy workers, enjoying the sunlight shining through the glass, and the whole room seemed a lot brighter. (To be continued.) )
