Chapter 116 Blast Furnace
After hearing about the magnetic separation method, Buck really couldn't think of any way to improve glass production.

Allen did not mention the float method in the past 10 minutes, but still explained how to blow the hollow iron pipe for everyone.

Buck was like an ant on a hot pot, wandering around in a hurry, waiting for a long time before the next class started.

"End of the hollow iron pipe suction method just now, let's talk about the float glass method next."

"First of all, the float method is a method of making flat glass. The principle is to use molten tin to spread in a groove, and then pour the molten glass into the tin groove. The molten glass will spread out on the surface of the molten tin. After it cools, it is slowly annealed, and the flat glass is formed."

What Allen said next was very advanced, and many people wondered why the molten liquid of the tin mine of tomorrow does not mix with the molten glass.

As an experienced glass master, Buck also couldn't understand, but this did not prevent him from admiring Allen.

"Too awesome!"

It was Barabara talking again, and Allen drank another saliva to let everyone digest the knowledge in their brains, and ask him any questions.

After talking about the technical details of the float, the orcs were already dizzy. I am afraid that the efficiency is extremely low, and it is difficult to teach people with a full-level teaching ability. Allen had to give up and tell them about the production method of optical glass tomorrow. .

Then Allen started the actual operation, first took them to experience a relatively normal hollow iron pipe blowing method, and first raised the temperature of the furnace.

Quartz sand is not prepared here, but is first crushed by a stone crushing machine powered by a steam engine, then selected and processed by water, and then sent to the glass factory.

At present, the sand seen by the orcs is already the product of the blacksmith's initial processing, and now lacks the magnetic separation step.

"This is the roller with the function of magnet?" Buck stared at the long workbench of the assembly line. There was a huge roller on it, which possessed the legendary magnetism.

"That's right, a huge natural magnet is installed inside the drum. The mineral sand passing through the drum will be attracted by the drum. There is a funnel for collecting the ore sand, and the other is for collecting magnetic products."

Allen pointed, and the slave used the hand-cranked bar under his guidance to drive the roller belt to drive the quartz sand. The sand passed through the magnetic separation drum, and there was a sound of falling sand immediately.

Some sand falls into the magnetic product collection bucket, and some low magnetic product collection buckets.

After a while of busy work, the milky white crystal quartz sand spread out in front of people, it is very small, pure, beautiful and moving.

It was the first time for Buck to see such a pure thing. He put a little quartz in the palm of his hand, and kneaded it gently, feeling a rustling friction.

"Master Allen, is this quartz sand?" Buck's throat groaned, with a desire to eat the sand.

"Yes, the next step is the melting link, adding soda ash, and then calcining it into a liquid."

"It's melted, bring the iron pipe, each of you will take one, and dip one end into the glass fluid..."

The end of the iron pipe was immediately stained with red liquid, and the hot air rushed to the face.

"It's ready to blow, use your mouth to block the other end of the hollow iron pipe, and work in groups of two."

"Yes, that's it, blow hard."

"Look, the glass fluid is bulging..."

Allen's voice rang out in the glass factory from time to time. After the first round of teaching, the method steps planted by Allen had been deeply imprinted in the minds of slave apprentices. Even if they didn't know the principles of tomorrow, they could still make glass by rote bottle.

When the first round of glass bottles were made, the slaves were so amazed that they made the glass bottle by themselves, and that it was transparent and free of color.

Buck's reaction was more intense. A theory is a theory. When the theory failed in practice, he still had a little doubt in his heart.

The moment he saw the transparent glass, he no longer had any doubts in his heart.

"It's very transparent, without any color at all." At some point, Buck knelt on the ground with his legs, observing the transparent glass he made by himself from an angle of looking up.

Seeing Buck worship so much made Alan himself very satisfied, which was one of the few joys in a monotonous life.

Half an hour later, Buck looked at Allen eagerly, "Master Allen, when will we use the float method to make glass?"

"At present, we have to wait for the orc laboratory to prepare the protective gas, and then wait, we will temporarily sell transparent glass bottles." Allen shook his head.

Although the float method is advanced and convenient, it also needs the support of industrial capabilities.

There is no nitrogen and hydrogen in the tin bath to prevent the oxidation reaction of the tin liquid, which will produce tin oxide and tin dioxide, which will cause various defects in the glass, such as tin penetration, optical distortion, fog spots, and small bubbles in the opening under the plate.

Allen is not in a hurry. Transparent glass bottles are enough to impact the existing glass market. When the market is saturated, the next glass product can be launched.

Besides, the microscope made of optical glass is the key to breaking the superstition of the Fox Village people, and the float method is not in a hurry.

Allen left the glass factory and let them continue to make exquisite glass crafts, which will be sold by merchants in Tomorrow Town.

Leaving the glass factory, Allen went straight to the ironworks.

The ironworks had been under construction for so long, and it was finally officially completed today. The orcs were waiting for him to use the identification technique to identify the ironmaking blast furnace to see if the state of the blast furnace was qualified, and then began the era of large-scale ironmaking in the blast furnace.

At present, the ironworks is equipped with blast furnace ironmaking equipment, which occupies a huge area. At the same time, the amount of ironmaking is astonishing, enough to break through the ironmaking output of a small workshop like a blacksmith's shop.

For this epoch-making factory, the orcs are undoubtedly excited, but they still don't realize that this will change the Lionheart Kingdom. They only feel that Tomorrow Town is getting stronger and stronger.

In the ironworks, a group of cat-eared orcs were already guarding the door, walking back and forth impatiently, until they saw Alan approaching from a distance, and then slowed down a little.

"Master Alan, you are here, come and see if the blast furnace we made is qualified." Abel came running in a hurry.

"Don't worry, haven't I just come back from the glass factory?"

"The glass factory?"

Abel muttered, secretly reassuring, maybe this thing is the next super machine, similar to a steam engine.

In the front, the tall iron-making blast furnace sits in the center of the iron-making plant. It is very large and full of architectural beauty.

At the top of the blast furnace, there is also a lifting device driven by a steam engine.

The top of the blast furnace is where the iron ore enters, and it is very troublesome to carry the iron ore to the blast furnace by manpower, so there is this lifting platform combined with pulleys and rope tools to transport the iron ore to the top of the blast furnace.

Of course, the rope is not a linen rope, but a helical steel wire rope. This is Abel's latest masterpiece. It is made of steel wire, rope core and grease, which is extremely strong and reliable.

Allen walked under the blast furnace, gently touched the wall with his hand, and secretly activated the identification technique.

　The recent chapters have to check the information, and the code speed is slowing down.
