Chapter 150 The First Batch of Glass Was Successfully Manufactured

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

Duan Chun understood that only by putting all these raw materials into the pot.

Heating to more than a thousand degrees and melting all the raw materials can get the red glass pulp.

Through the drip cutting method, these materials are clipped out while hot.

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

Then quench and heat it to ensure that the tension of the glass subsides, so that the glassware produced will not be damaged.

Finally, heat it again, and after cooling, it will become the desired commercial goods...

But this time, Duan Chun wanted to make the simplest glass cups and glass bowls in the first batch.

And test tubes and beakers, alcohol lamp holders and culture dishes, etc.

Waiting for the temperature of the three furnaces to rise gradually, the temperature in the workshop gradually became hotter.

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

The person in charge said.

"It doesn't matter, it's the first time to burn glass."

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

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

This is the best temperature for calcining raw materials.

And here, it is a sheltered place, and the location of the furnace is close to the cliff.

The temperature can be raised quickly.

As time goes by, the temperature in the workshop is rising again and again.

It is almost reaching a high temperature of 40 degrees, and Duan Chun and the craftsmen's foreheads.

All have fine beads of sweat.

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

The person in charge reminded.

The major general instructed that the three furnaces must reach the level of melting copper blocks.

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

And they have become bent, and the height has been continuously reduced piece by piece.

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

If copper can be melted, it can ensure that the temperature reaches the temperature for firing glass.

"Put in the raw materials according to the proportion."

"Be careful of burns!"

Duan Chun immediately ordered.

"Here!"

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

"65% sand, 25% ash, 15% stone."

Duan Chun recited aloud.

This is the ordinary glass formula ratio he learned from memory.

As for whether it works?

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

"Here!"

The craftsmen waved iron shovels and put the materials into the three firing troughs one by one according to the proportion.

The three firing troughs were all tilted on the stove.

As long as the materials are burned into raw pulp, they will continue to drip towards the tilted side.

And the craftsmen are curiously waiting, according to the method said by the major general.

Can the scene of burning sand and stone into water really appear?

As the raw materials filled the three stone troughs.

At this time, the three copper bars have been completely melted.

As everyone watched with sweat, the various materials in the three stone troughs continued to fall.

The red solution appeared at the bottom of the stone trough!

"Stones can really be burned into water!"

"It's amazing!"

A group of craftsmen were ecstatic...

"Is the mold ready?"

"We'll cut the raw pulp later and try it a few more times."

"Don't be afraid of failure."

Duan Chun shouted.

"Major General, the mold is ready."

The craftsmen replied.

On one side of the three quenching tables, the molds made of yellow mud were already there.

The three craftsmen also held pliers and blowpipes, ready to be on standby at any time.

Yesterday, the major general had already taught them how to blow the fire.

Now it depends on their skills.

All the craftsmen knew that what the major general taught them was something that had never appeared before.

If they could make it successfully, they would be able to make money continuously in the future!

They must seize this opportunity.

"The raw pulp is out!"

With a surprised roar from a craftsman.

Under the continuous calcination of the furnace, the raw materials all turned into red pulp.

It was slowly flowing out towards the inclined stone trough...

Duan Chun breathed a sigh of relief.

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

Fortunately, he used to like watching videos, especially those video operations of scientific and technological processes.

The raw material slurry that was calcined did not flow freely like a metal solution.

This glass slurry was like red plasticine, slowly flowing down.

As a piece of red slurry hung at the end of the stone trough, it did not fall directly.

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

Holding a piece of slurry, he hurried 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.

Just want to see if the experiment can be successful?

The quenching table also burned with flames, continuously heating the mold.

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

The three craftsmen who had been waiting on the side immediately took the blowpipe to blow air into the mold entrance.

The slurry was under the pressure of the gas, and there was a small opening on the other side of the mold.

It was sucked and stretched by the pressure from front and back.

A mass of raw pulp immediately spread out inside the mold...

It's 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...
