The Emperor's Son-in-Law

Looking at the various raw materials piled up on one side of the workshop.

Duan Chun understood that the only way was to put all these raw materials into the pot.

Heating it to more than a thousand degrees and melting all the raw materials, you can get a bright red glass slurry.

These materials are pinched out while hot by drip cutting.

Then put it into the mold and blow it into the shape you want.

Then it is quenched and heated to ensure that the tension of the glass is reduced, so that the manufactured glassware will not be damaged.

Finally, heat it up, and after cooling it can become the desired product...

But this time, Duan Chun’s first batch of products were the simplest glasses and glass bowls.

As well as test tubes and beakers, alcohol lamp holders and petri dishes, etc.

Waiting for the temperature of the three stoves to gradually rise, the temperature in the workshop also gradually became hot.

"Major General, it's too hot here, you'd better watch from outside."

The chief said.

"No problem, it's my first time firing colored glaze."

"I had to see it with my own eyes."

Duan Chun shook his head. He knew very well that the temperature of the stove must reach between 1100 and 1600 degrees.

is the optimal temperature for calcining raw materials.

And this is a sheltered place from the wind, and the stove is located close to the cliff.

The temperature can rise quickly.

As time continues to pass, the temperature in the workshop continues to rise significantly.

The temperature was almost reaching forty degrees on the foreheads of Duan Chun and the craftsmen.

Beads of sweat broke out all over.

"Major General, the furnace temperature is almost up."

The chief reminded.

The major general explained that the three furnaces must be able to melt copper blocks.

Now he has seen that the copper bars inserted in the three furnaces have been burned red.

And it became curved, and the height continued to decrease section by section.

Duan Chun also saw that the melting point of copper is less than 1100 degrees, but higher than 1000 degrees.

If you can melt copper, you can ensure that the temperature reaches the temperature required for firing glass.

"Put in the raw materials in proportion."

"Be careful of burns!"

Duan Chun immediately ordered.

"Here!"

A group of craftsmen picked up shovels, scooped up various materials and quickly threw them into the stone trough.

"Sixty-five percent sand, two-and-a-half percent ash, and one-and-a-half percent stone."

Duan Chun read loudly.

These were the common glass recipe proportions he had learned from memory.

As for whether it works?

He has never tried it before, so he can only wait and see the situation first.

"Here!"

The craftsmen wielded shovels and put the materials into the three firing tanks one by one in proportion.

The three firing tanks are all tilted on the stove.

As long as the material is burned into pure pulp, it will continue to drip towards the tilted side.

The craftsmen were waiting curiously, following the method the major general said.

Is it possible to really burn sand and gravel into water?

Three stone troughs were filled with raw materials.

By this time, the three copper bars had completely melted.

As everyone watched, dripping with sweat, they saw various materials in the three stone troughs falling continuously.

The red solution suddenly appeared at the bottom of the stone tank!

"Stones can really be boiled into water!"

"It's so amazing!"

A group of craftsmen were all pleasantly surprised...

"Is the mold ready?"

"Cut the puree later and let's test it a few more times."

"Don't be afraid of failure."

Duan Chun shouted.

"Major General, the mold is ready."

The craftsmen replied.

I saw only one side of the three quenching tables, where the molds prepared with yellow mud had been placed.

The three craftsmen also had iron tongs and blowpipes, ready to go.

Yesterday, the Major General taught them how to blow fire.

Now it depends on their ability.

All the craftsmen knew that what the Major General taught them was something that had never been seen before.

If you can build it successfully, you will be able to earn money continuously in the future!

They must seize this opportunity.

"The puree is out!"

With a craftsman roaring in surprise.

Under the continuous calcination of the stove, all the raw materials turned into red slurry.

It is slowly flowing out towards the sloping stone slot...

Duan Chun let out a sigh of relief.

The knowledge I learned from books when I was studying is indeed true!

Fortunately, he used to like to watch videos, especially those about technology and crafts operations.

The slurry of calcined raw materials does not flow freely like a metal solution.

This glass puree is like red plasticine, slowly flowing downwards.

A piece of red raw pulp hung at the end of the stone trough, but did not fall directly.

The three craftsmen immediately held the bottom with iron pliers and cut it into two pieces with iron scissors in the other hand.

With a piece of puree in his pocket, he quickly ran to the quenching table and got busy.

This time it was just an experiment, and Duan Chun did not set up too many quenching tables.

I just want to see if the experiment can be completed?

The quenching table is also burning with flames to continuously heat the mold.

As the three craftsmen quickly put the glass slurry into the mold entrance.

The three craftsmen who had been waiting aside immediately took a blowpipe and blew air into the entrance of the mold.

The slurry is pressurized by the gas, leaving a small opening on the other side of the mold.

He was sucked in one by the pressure from the front and back.

A lump of raw pulp immediately spread inside the mold...

You're done!

Duan Chun saw with his own eyes the moment when the three pieces of glass pulp entered the mold.

He had a smile on his face.

Making this kind of glassware is the simplest process of firing glass.

You know, glass craftsmen can make all kinds of glass artworks.

The difficulty of making this kind of object is increased by hundreds and thousands of times!

As long as the craftsmen quickly familiarize themselves with the crafting skills, various glass crafts will increase greatly in the future.

And add different raw materials and calcine the materials at different temperatures.

You can also get various types of glass.

What quartz glass, tempered glass, special glass, etc.

There are too many types...

Like this kind of glassware with simple shape and no process.

Just blow it into shape.

After the three molds were simply blown and pulled by the blowpipes of the three craftsmen.

The glass pulp was affected by the wind and quickly fit the shape of the mold.

Part of the hot air was discharged backward along the ventilation duct.

"You can take it out and continue quenching."

"Prevent them from breaking and increase the firmness of the object."

Duan Chun reminded immediately.

"Here!"

The craftsmen standing by immediately opened the mold.

Three craftsmen holding pliers carefully took out the dark red glassware that had been formed in the mold.

Then they put it on the quenching table and rotated it to heat it.

Looking at the three heating cups for the experiment appearing in front of him.

Duan Chun was inexplicably excited...

Once the glassware is made, he will not promote it now.

He just wants the craftsmen to master the skills and make some large objects as gifts for His Majesty the Emperor.

Then wait until the number of processes is sufficient for mass production and then sell it at a high price...

This kind of glass made of water cups, fish tanks, mirrors and the like.

It is definitely a best-selling product!

You know, the ancients still used bronze mirrors.

The effect of bronze mirrors is far, far worse than that of glass mirrors...
