This morning, Owen received a notification from Viru that the glass furnace had been built as required.In this way, the town of Bianshu can also start producing glass products, which is really a good thing.In the Kingdom of Dawnlight, the art of making glass is only in the hands of a few families of glass craftsmen, after all, it is an ancestral skill.As a result, glassmakers were often favoured by the local lords, and the manufacture of glass generally became an important industry in the region, creating a great deal of wealth for the lords.It's just that most of the glass made by those glass craftsmen has a variety of colors, the most abundant is green glass, and the transparent and colorless glass is the rarest.As the saying goes, rare colorless transparent glass is quickly popularized as a luxury, and only by owning it can it show a noble identity, and the price is extremely high, and generally only nobles and wealthy merchants can afford it.There were no glass craftsmen in the border town, so all glass products could only be purchased from other places.Owen had always thought that making glass was a very advanced technology that only a few glass craftsmen could study and master.It wasn't until he learned about the production process of glass from Winster that he was shocked.The main raw material needed to make glass turned out to be sand, or quartz sand in sand, that is, silica.Moreover, the principle of manufacturing 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 the raw material is mixed with other impurities, mainly iron oxide, which makes the glass 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 profitable it is.Since he is so profitable, Owen doesn't mind mixing in and making a lot of money from it.Of course, making money is secondary, and Owen has other purposes for producing glass, that is, to make glass laboratory equipment and concave and convex lenses.Needless to say, experimental equipment, such as Erlenmeyer flasks, glasses, test tubes, etc., are glass products, which are needed to do chemical experiments in the laboratory.At present, most of the equipment in the temporary laboratory has been transferred from Winster, and some of it has been remelted by Owen from the transparent and colorless glass products in his home.Those are all exquisite glass products that the Eisen family bought at a great price, but in the end they became equipment in the laboratory, which feels a bit of a loser.Whereas, concave-convex lenses are used to make telescopes.With the advent of artillery, it is now possible to hit targets at a farther distance, and it is somewhat unreliable to judge by the human eye alone, so the telescope is needed as an auxiliary tool.In addition to military use, Owen also intends to market to the Twins.As a member of the Gorge Federation, President Marsha must have sailed a lot to carry out various trade activities.In the vast sea, if you can have an aid to increase the viewing distance, the navigation will be safer.Such a great auxiliary tool will definitely sell well on the Gorge Moon Alliance.Without further ado, Owen sent someone to transport the raw materials and tools that had been prepared, and then took Marpel to his destination and prepared to show his skills.Since the kiln that can burn cement has recently been put into production, and the cement supply is temporarily sufficient, Owen called Fanny, who was finally idle.The type of glass melting kiln built by Viru is a crucible kiln, the inner wall of the kiln is built with a layer of refractory bricks, and the crucible for melting glass is also made of refractory clay.While Owen inspected the crucible kiln, two guards pushed wooden carts to carry raw materials and tools."
Huh?"
When she saw the vat of sand that had arrived, Fanny looked puzzled and asked, "My lord, didn't you say you wanted to make glass?"
”"yes."
Owen walked over, grabbed a small handful of sand, and said, "This sand is an important raw material for making glass." ”"Huh?!"
Fanny was stunned, "You want to make glass out of sand?"
Lord, are you sure you're not kidding me?
”She had the impression that the fine glasswork and the sand everywhere on the ground were two different things, and that there could be no connection between them.Marpel also looked incredulous, she also has glass products at home, the price is not low, isn't it made of precious raw materials?"
I'm not kidding."
The corners of Owen's mouth went up, "When the finished product is made, you will believe me." ”The raw materials shipped are all pre-processed, and the bulk raw materials are crushed and dried.It is worth mentioning that the sand used as the main raw material is not ordinary sand, but was dug by soldiers from the Make Desert in the north of the border town.Winster's tests showed that the sand formed by the curse was pure, with little to no other impurities such as iron oxide, and that the sand had to be removed from the iron.Without those messy impurities, the resulting glass is certainly the rarest and most expensive colorless transparent.If the border town can produce a large amount of colorless glass, it will inevitably impact the high price of colorless glass, and then cause the dissatisfaction of the lords of the original glass production area.But so what?
They have made a lot of money by monopolizing the manufacture of glass.Perhaps the taste of lying down to make money is so comfortable that they have long since become unenterprising.After all these years, glass manufacturing technology has not improved at all, and it is time to spur it on.Now, let's start making glass.First, mix all kinds of raw materials (sand, soda ash, etc.) according to the appropriate ratio.Next, the mixed glass mixture is poured into the crucible and placed inside the crucible kiln.Magic, the mana output should be increased until I say yes, and then it can be turned into a stable output. ”"No problem."
Fanny nodded, walked up with her staff in hand, and began to cast a fire-based magic, the Pillar of Fire.Owen, on the other hand, turned on the data visualization function and looked at the temperature values.When the temperature rose to the right level, he immediately made a voice for Fanny to stabilize the mana output.Under high temperature heating, the glass ingredients gradually melt and finally form a uniform, bubble-free glass liquid that meets the molding requirements.Seeing this, Owen reminded: "It's okay." ”Hearing this, Fanny nodded, immediately withdrew her magic, and then exhaled lightly.Compared to 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 molten glass.After picking the material, roll the spoon on the rolling board, and you can start blowing at the other end, turning as you blow.This is known as glassblowing, and glass craftsmen probably use this method to shape glass.This lord is backed by a tech tycoon
