Chapter 115 Magnetic Separation
After Buck finished speaking, the other slave orcs scratched their heads. They had all worked in blacksmith shops, and they only understood sand and salt and high-temperature calcination. When Buck mentioned that the hollow iron pipe blows air, they entered a misunderstanding of knowledge and were at a loss. .

"Master Alan, how do you blow it, do you blow it with your mouth?" the slaves subconsciously asked Alan.

They are not novices, and they know that Alan's teaching ability is very strong. When they have a question, their first thought is to ask Alan.

When Buck heard the slave's question, he immediately realized that his opportunity had come. As long as Allen couldn't answer, he could show it.

However, things were not as he thought, Allen nodded: "Yes, blow with your mouth."

Buck was surprised, he didn't expect Allen to know how to blow hollow iron pipes!
"Guess, definitely guess, Alan can't know." Buck continued to comfort himself in his heart.

Allen's mouth didn't stop, and further revealed the secret:

"The hollow iron pipe blowing method requires a very thin iron pipe, and you can experience this method later.

The specific operation steps are to dip one end of the iron pipe into the sticky glass liquid, stick your mouth to the hollow iron pipe, and blow with a big mouth, and then you will find that the glass liquid is blown into a round jar by you. "

This is the core secret of the glass maker, and it is rarely revealed to outsiders unless the other party has power and money.

Buck was so shocked that he couldn't close his jaw, and thought it was impossible.

But then I thought about it, isn't Alan just the kind of person with power and money?

Buck returned to his normal expression, silently nodded in agreement.

After Allen finished speaking, he said again: "But this is not the focus of today. I said that I will bring advanced glass production methods and will not adopt production methods that are outdated by the times."

"Master Alan, the glass masters in South Bank Town are trying to find new materials to enhance the transparency of the glass, but it's too difficult." Buck shook his head slightly, not believing that Alan has superior glass-making technology than the contemporary cutting-edge.

"Transparency? It's actually a very simple issue."

Allen smiled, and after attracting Buck Lion's attention, he explained: "The sand used in ordinary glass is not pure, and there are a lot of impurities in it. They are the key to the color of the glass."

Buck is a glass technician in Nan'an Town, and he is very clear about the glass production process. Once Alan mentioned it, he immediately felt that Alan's words made sense.

"Then how do we get rid of those impurities? The sand is already very small and fine, and the impurities hidden in it must also be very fine and small, which is difficult to filter out."

Allen was satisfied with his reflective behavior, but the other orcs were a little confused.

Until Alan walked to a certain wall of the glass factory and removed the linen sheet, a blackboard appeared in front of the orc.

Buck is a resident who just arrived yesterday, and he doesn't know about chalk and blackboard. Seeing Alan write and draw on the blackboard with white chalk, a lifelike method of purifying sand spread out in front of his eyes.

"So the next concept I want to mention is quartz sand, which is a kind of sand made of crushed quartz stone minerals, and quartz is a very common mineral. Today, orc slaves have dug up the magma rock from the extinct volcano. Come here, there is a lot of quartz stone in it."

Allen taught people by dictation, and hand-painted graphics to perfect the poor thinking ability of the orcs. The sound of each sentence automatically comes with a slight hypnotic power, secretly instilling knowledge into every orc.

The slaves had a general understanding of the specific operation steps and knew how to make quartz sand.

"This is, what kind of recording method is this? It's so simple and straightforward that I can understand it almost immediately." Buck's mouth has not been closed since the blackboard appeared.

Seeing those vivid patterns dancing on the blackboard, he seemed to have personally come to the quartz sand production site, watching those rocks being ground, sorted, washed and processed by a large machine with strange power, and then to the next highlight technology, that is, Barker Never-before-seen technology - Magnetic Separation!
Magnetic separation uses the principle of different magnetic permeability of various minerals to further screen different magnetic minerals.

The smallness of this step is no longer the point, it is only about the magnetic level!
Buck listened to this miraculous selection of thoughts, his brain was trembling, and his tail stood on end with excitement.

If Alan hadn't warned him with his eyes not to let his exaggerated movements disturb other slaves studying, he would have almost knelt down and shouted for master.

"A magnet is a stone that can absorb iron. Our magnetic separation equipment needs magnetic rollers, material distribution plates, vibration plates, etc., which can remove strong magnetic minerals, and can also remove weak magnetic hematite and limonite to the greatest extent. ore and biotite and other impurity grain minerals."

Every word of Allen was unremarkable, but it exploded like a bomb in Buck's ears.

Afterwards, there was a large-scale image explanation. The chalk on the blackboard wrote and erased, and explained in detail why it was done, what its principle is, what is the effect of this method, and what are its advantages and disadvantages.

Of course, there are also a little bit of technical secrets in it. For example, Allen has the identification technique, which can identify the magnetic rate, and accurately manufacture weak magnetic separation and strong magnetic separation equipment.

Buck was a little confused about how to make magnetic separation equipment, but Alan didn't go into details, and he couldn't help it.

A few strange ore names popped out of Alan's mouth, and he also needed to ask Alan what it was afterward. After all, he was not a mineral expert, and it was impossible to know the characteristics of all minerals.

After talking about the low-cost and easy-to-understand magnetic separation method, Allen talked about the detailed operation steps of the hollow iron pipe blowing method.

For now, Allen has not abandoned the hollow iron pipe blowing method.

Barabara paused, and half an hour of class was over. Allen took a sip of water and said, "Everyone take a 10-minute break to digest the knowledge just now, and answer any questions. After 10 minutes, we will talk about float glass. It doesn't matter if you haven't finished digesting it, Buck." Mr. will work hard to digest my knowledge, and he will slowly teach everyone how to make it afterwards."

Buck, a glass maker from Nan'an Town, lowered his head to reflect on the question. When he heard Alan's words, he raised his head suddenly, and couldn't hold back his surprised voice:
"What! And how to make glass?"

　Second watch, sleep.
