The Last Alchemist

Although Savi is white and fat, when it comes to making glass, he still has two brushes.

He first put on a thick cowhide apron and insulated cowhide gloves, skillfully added raw materials to the iron pot, stirred evenly, and then started to light the fire. After the fire was fully heated, he started to pull the bellows.

‘Hu~chi~hu~chi~’

The flame in the furnace suddenly became very fierce, and the bright yellow flame tightly wrapped around the crucible. After a period of time, the raw materials in the crucible began to react and melt.

"Rosen, let's start stirring." Savvy added evenly sized charcoal to the stove while pulling the bellows hard.

Rosen looked around and saw an iron rod with a cloth wrapped at one end beside the crucible. He put on insulated leather gloves, picked up the iron rod, put it into the crucible and stirred it continuously.

At first, the iron rod felt a little astringent when stirring, but the more it stirred, the lighter it became. Gradually, Rosen felt as if he was stirring a pot of sticky maltose. It felt very light and slightly sticky. There was also a sound of "chichi gurgling" water.

Savi glanced into the crucible and nodded: "That's almost it."

Rosen took out the iron rod for stirring, and saw that one end of the iron rod was covered with a mass of molten glass that glowed red and had a texture like thick honey. Under high temperature, the molten glass looked quite beautiful.

However, laymen watch the excitement, and experts watch the door. Savvy shook his head when he saw the molten glass: "No, no, your technique is wrong, too many bubbles are mixed in."

Rosen also saw bubbles. A large number of fine bubbles could be seen in the glass melt he stirred out, which greatly affected the transparency of the glass.

"How do you usually remove air bubbles?"

Savi reached out and wiped the sweat from his forehead: "We can only wait. If the melting time is longer, the bubbles will slowly come out, but this consumes a lot of charcoal. There are too many bubbles in our furnace, so it is considered useless. The things made can only be sold as defective products.”

"That's not necessarily the case."

Rosen smiled slightly. He put the iron rod back into the molten glass and began to stir it gently. At the same time, he was immersed in his mind and activated his alchemical power.

The power of thought extended into the crucible, grabbed the bubbles in the molten glass, and pulled them out.

If someone looks at the molten glass at this time, they will find that the bubbles in the molten liquid suddenly accelerate to rise. In just 4 seconds, all the air in the molten glass is evacuated.

But that's not all.

The glass fired by Savi always has a light green color, but pure silicate glass should be colorless and transparent. The reason why it is green is because there are some divalent iron impurities mixed in the raw materials. As long as the impurities are removed, it will can solve this problem.

Rosen carefully sensed the situation in the molten glass. After a few seconds, he felt the presence of many special auras.

There are many kinds of scents, the vast majority of which are naturally glass, and the rest are very rare, but they do exist.

‘The second-level elemental friends are really good. If it were before, I would definitely not be able to find so many impurities, let alone remove them. But after the ability is improved, there won’t be much of a problem. ’

Glass melt is a liquid, and the molecules and atoms in it can move freely. If Rosen wants to remove impurities, he only needs to overcome the intermolecular force, which is not difficult.

Rosen was very familiar with this process. He not only removed the ferrous iron ions, but also separated out all other impurities. Soon, only pure molten glass remained in the crucible.

About three minutes later, he withdrew his alchemy power and walked to the side to get the clay mold: "That's it. Let's start pouring the glass juice."

"Hey, didn't you say that the mold can't be used?" Savi raised his hand to wipe the sweat from his forehead, his eyes full of confusion.

Rosen smiled slightly: "You can't use it, but I can still use it. Come down quickly."

"." Savvy was speechless, but at this point, he could only choose to believe Rosen.

He picked up the big iron clamp, clamped the entire crucible, then carefully moved it to the mold, and began to slowly pour the hot glass juice into the mold.

The moment the glass juice appeared, Visa's hand shook slightly: "Hiss~ How is that possible?!"

The glass juice before was filled with fine bubbles and the color was very turbid, but now the glass juice poured out has not only no bubbles at all, but also a crystal clear color, just like the most beautiful crystal in the world.

Savi has been a glassmaker for many years and has seen countless pieces of glass. He still has a good eye for it. As soon as he saw such a color, he knew that this pot of glass was definitely extraordinary.

"Keep your hands steady and keep pouring." Rosen urged.

"Oh, okay, okay."

Savi took a deep breath and continued pouring glass juice into the clay mold until the mold was filled. Then he carefully placed the crucible back on the stove.

"How long does it take for the glass to get cold?" Rosen asked.

"It takes about twenty breaths, so it won't be long."

While speaking, Savi's eyes were still staring at the glass in the mold, as if looking at a rare treasure.

Rosen ignored him, he quickly activated his alchemy power, and his tentacles of thought penetrated the glass juice in the mold.

‘A good lens must not only have good light transmittance, but also have a perfect shape. These are all related to the order of molecular arrangement. The last time I prepared nitroglycerin, I had a completely new understanding of quantum electrodynamics, so I just used this piece of glass to practice my skills. ’

As Rosen thought, the molten glass in the mold seemed to be alive and began to surge slightly.

"God, it's moving, it's moving!" Savi, who was on the side, pointed his fat finger at the glass of juice, his eyes almost falling out of his sockets.

Rosen ignored him and continued to modify the glass.

After more than half a minute, the glass solution had basically cooled down and turned into a mass of colorless glass. It was highly transparent and crystal clear, as pure as a pool of solidified water. Just one look at it, and a strong feeling for beautiful things will arise in your heart.

"Incredible! Simply incredible! Perfect, like frozen moonlight!" Savvy murmured softly. He stared at the glass tightly, took the mold with one hand, and very carefully knocked out the solidified glass lens inside, holding it in his hand to watch carefully.

"Oh my God, it's so beautiful. How can there be such wonderful glass in the world?"

"No, this can never exist naturally, this must be magic!"

"Rosen, I just saw that the glass juice moved on its own. You must have used magic, right?"

"I used magic." Rosen nodded.

Savi was relieved: "That's right. Ordinary people will never be able to make such a flawless glass lens. Only magic can do it. My God, it is simply the most magnificent treasure in the world!"

The more Savi looked at it, the more he liked it, and the more he looked at it, the more reluctant he was to let go. For a moment, he even had the urge to use all his belongings to buy such a lens.

Naturally, Rosen didn't know what he was thinking. He smiled and said: "What you said is not wrong. It is indeed impossible for ordinary people to do it. However, if the only thing is to make the glass colorless, and it has 80% of the quality of this glass, , ordinary people can still barely complete it after a long period of practice.”

Savvy was shocked and immediately asked: "What should we do?"

Rosen laughed, raised a finger and shook it in front of him: "Savi, you should have heard a saying that there is no free pie in the world, right?"

Savi was excited and immediately said: "What price do I have to pay? As long as I can afford it, I will definitely pay it!"

"Pay me 1,000 rands now and the right to use this glass studio for three days. Also, during the time I use the studio, you have to be my assistant for free. As a reward, I will give you a colorless The recipe for glass, and the complete method of creating a magic lens, if you would like to know more about the principles, I will teach you some geometrical optics.”

"How many new methods are there to create magic lenses? Geometric optics? Is this true? Can I learn such a profound principle?" Savi was stunned again.

1,000 rand is a lot, but he can barely afford it. If he can learn a new skill, what does this little money mean?

The right to use the glass studio for three days and work as Rosen's assistant was something he could not have wished for more. But what Rosen said at the end made him yearn for and feel anxious at the same time.

Although he really wanted to know the principle of the magic mirror, in his opinion, the magic mirror was really wonderful, and the principle behind it must be extremely profound. His mind was too stupid, and he might not be able to understand the mystery.

Rosen raised a finger and waved his hand in front of him: "Don't worry, I will teach you until you fully understand."

Geometric optics is nothing more than refraction and reflection of light. If you can't understand this, you are a fool.

The doubts in Savvy's heart disappeared. He was so excited that his whole body was trembling: "No problem, absolutely no problem. Don't say it will be three days, one month, or one year. There will be no problem. I will get rid of it now." Get the money for you!”

By now, he had no doubts about Rosen's alchemy skills. As soon as he finished speaking, he ran to the front shop. A few minutes later, he ran back with a bulging money bag: " Master, the money is here, please order it.”

Rosen weighed it with his hands for a moment, then put the money bag aside: "Very good, let's start now. Let's repair the Baron's magic mirror first, and then I need to make some glass molds. Of course, these utensils All required materials are your responsibility.”

Savvy deserved to be very straightforward: "Master, there is no problem. You can do whatever you want, and I will never complain."
