This morning, Owen received a notification from Vilu, saying that the glass melting furnace had been built as required.

In this way, Bianshu Town can also start producing glass products, which is really a happy thing.

In the Kingdom of Morning Light, the technology of making glass is only in the hands of a few families of glass craftsmen. After all, it is an ancestral skill.

Because of this, glass craftsmen usually receive preferential treatment from local lords, and making glass generally becomes an important industry in the place, creating a lot of wealth for the lords.

It's just that most of the glass made by glass craftsmen comes in various colors, with green glass being the most abundant, and transparent colorless glass being the rarest.

As the saying goes, rare things are valuable, and rare colorless transparent glass was quickly praised as a luxury product. Owning it can show your noble status. The price is extremely high, and generally only nobles and wealthy businessmen can afford it.

There are no glass craftsmen in Bianshu Town, so all glass products can only be purchased from outside.

Owen has always believed that making glass is a very advanced technology that only a few glass craftsmen can study and master.

It wasn't until he learned about the glass production process from Winster that he was shocked.

The main raw material needed to make glass turns out to be sand, or quartz sand in sand, that is, silica.

Moreover, the manufacturing principle is also very simple, which has been monopolized by glass craftsmen for so long.

Not only that, Owen also learned that the reason why glass has color is because other impurities are mixed into the raw materials, mainly iron oxide, which causes the glass produced to be mostly green.

The cost of making glass is not high, but the price of glass products circulating in the market is not low, which shows how huge the profits are.

Since it is so profitable, Irving doesn't mind getting involved and making a lot of money from it.

Of course, making money is only secondary. Owen also has other purposes for producing glass, which is to manufacture glass experimental equipment and meniscus lenses.

Needless to say, experimental equipment, such as Erlenmeyer flasks, glasses, test tubes, etc., are all glass products, and they are needed for chemical experiments in the laboratory.

Currently, most of the equipment in the temporary laboratory were previously transferred from Winster, and some were made by Owen's transparent and colorless glass products that he remelted.

Those are all exquisite glass products that the Eisen family spent a lot of money to buy, but in the end they were turned into laboratory equipment, which feels a bit like a waste.

Meniscus lenses are used to make telescopes.

With the emergence of artillery, the distance that can hit targets is now even further. It is unreliable to rely on human eyes to judge, so a telescope is needed as an auxiliary tool.

In addition to military uses, Owen also plans to sell it to the Twin Chamber of Commerce.

As a member of the Xiayue Federation, President Masha must have often sailed to conduct various trade activities.

On the vast sea, if you can have an auxiliary tool to increase the observation distance, navigation will become safer.

Such a great auxiliary tool will definitely sell well in the Xiayue Alliance.

Without further ado, Irving immediately sent someone to transport the raw materials and tools that had been prepared, and then brought Marpel to the destination eagerly, ready to show off his skills.

Since the kiln capable of firing cement has recently been put into production, the supply of cement is temporarily sufficient, so Owen called Fanny over, who was finally free.

The type of glass melting furnace built by Viru is a crucible kiln. The inner wall of the kiln is lined with a layer of refractory bricks, and the crucible for melting glass is also made of refractory clay.

While Owen was inspecting the crucible kiln, two guards pushed the wooden carts to move the raw materials and tools.

"Eh?"

When she saw the tank of sand being transported, Fanny showed a confused expression and asked, "Lord, didn't you say you want to make glass?"

"yes."

Owen came over, grabbed a handful of sand, and said, "This sand is an important raw material for making glass."

"Ah?!" Fanny was stunned, "You want to use sand to make glass? Lord, are you sure you are not kidding me?"

In her mind, exquisite glass products and the sand that can be seen everywhere on the ground are completely different things, and there is no connection between them.

Mapel also looked in disbelief. She also had glass products at home. The price was not low. Wasn't it made of precious raw materials?

"I'm not joking." Owen raised his lips, "You will believe me when the finished product is produced."

The raw materials shipped have been pre-processed, and the bulk raw materials have been crushed and dried.

It is worth mentioning that the sand used as the main raw material is not ordinary sand, but soldiers were sent to dig it from the Mark Desert in the north of Bianzhu Town.

After testing by Winster, the sand formed by the curse is very pure and contains almost no other impurities such as iron oxide. It can also save the step of removing iron from the sand.

Without those messy impurities, the glass produced must be the rarest and most expensive colorless and transparent.

If Bianzhu Town could produce a large amount of colorless glass, it would inevitably impact the high price of colorless glass, which would in turn cause dissatisfaction among the lords of the original glass production area.

But so what? They have made a lot of money by monopolizing the manufacturing of glass. Perhaps the feeling of lying down and making money is so comfortable that they have long since become unwilling to make progress.

After so many years, glass manufacturing technology has not improved at all. It is time to give some encouragement.

Now, let's start making the glass.

First, mix the various raw materials (sand, soda ash, etc.) evenly in appropriate proportions.

Then, pour the mixed glass batch into the crucible and place it inside the crucible kiln.

The next step is the melting process. Owen turned to Fanny and ordered: "Please use magic. The magic output must continue to increase until I say it's OK before it can be converted to a stable output."

"no problem."

Fanny nodded, walked up with a staff in hand, and began to cast fire magic - Pillar of Fire.

Irving opened the data visualization function on the side and checked the temperature values.

When the temperature rose to a suitable value, he immediately asked Fanny to stabilize the magic output.

Under high-temperature heating, the glass ingredients gradually melt, eventually forming a uniform, bubble-free glass liquid that meets the molding requirements.

Seeing this, Owen reminded: "That's it."

Hearing this, Fanny nodded, immediately withdrew her magic, and then breathed out lightly.

Compared with firing cement, the work of melting glass is relatively easy.

Next, Owen took out a hollow iron pipe about 1.5 meters long and put one end into the kiln to dip it in the glass liquid.

After picking the ingredients, roll the spoon on the rolling plate, and then start blowing at the other end, turning while blowing.
Chapter completed!
