The craftsmen burned the liquid glass according to the method taught by Yu Xiaotian, and then made the liquid glass into flat glass, but the largest plate glass they have made so far is only one foot by two feet square, and no matter how large the plate glass is, they are not very easy to make.

Before Yu Xiaotian went to the station, he asked them to try out a larger plate glass, and planned to use the large plate glass to make a large dressing mirror in the future, so that even if this thing was used as a tribute, it would definitely be able to sell at a sky-high price while shocking the business world.

However, the craftsmen tried and failed, they tried many times, and finally because the stress could not be dealt with, the annealing cracked, so this large-area flat glass is not as easy to do as Yu Xiaotian thought.

After Yu Xiaotian learned of this result, he was not too disappointed, although he couldn't do a large dressing mirror, but this two-square-foot glass mirror is already quite good, many things are not achieved overnight, and it takes a lot of time to gradually explore to make the technique gradually perfect.

Some time-traveling novels say that pig's feet are like gods, and all kinds of advanced things are made day and night, which is simply impossible.

He has been here for two years, and he knows that even if he knows a lot of things, but in this era, it is not easy to copy what he has learned.

When he walked into the glass field, the heat was blowing here, and the temperature here was not at all low compared to iron and artillery, and even more so.

The craftsmen were busy in the shed, and they did not dare to go into battle shirtless, the temperature of the liquid glass was extremely high, and if it was slightly stained, it was a serious burn, so at the beginning, some craftsmen were accidentally burned, so now the craftsmen working here must wear thick canvas clothes, and at the same time cover a piece of whale skin.

Therefore, the working conditions here are very bad, and the craftsmen will suffer from heat stroke if they are not careful, so there is a large water tank at the door of the shed, in which a few water scoops are thrown, filled with cool boiled water, for the craftsmen to come out and drink at any time.

When Yu Xiaotian walked into the shed, several archers were each holding a hollow iron pipe, dipped in some molten glass, blowing hard, blowing the molten glass gradually, and then rolling it repeatedly on the iron plate and using some tools to shape it.

The piles of glass shards on the ground are scrapped pieces, but so far, they have not produced a few decent glass products.

As soon as he saw Yu Xiaotian, the steward here trotted in front of Yu Xiaotian, and was about to kneel down for Yu Xiaotian, Yu Xiaotian quickly grabbed him and said, "Don't!" Don't be polite, there's broken glass everywhere, don't prick your legs! Be careful! From now on, everyone will not kneel! ”

All the craftsmen hurriedly thanked them, stopped what they were doing, bowed their waists with smiling faces, and waited for Yu Xiaotian to speak, and many people showed a worried look on their faces.

Yu Xiaotian looked at it and waved his hand and said, "What should I do, continue to do something, don't delay things because I'm here!" What do you think? Executives, how are you doing here in my absence? ”

The executive used to be a person who was born in pottery, and after arriving here, he first helped to burn bricks and pottery for the sea wolf, and he was also a little good at making porcelain, and he was honest and down-to-earth and willing to work, and was discovered by Yu Xiaotian and handed over the glass field to him to manage.

The executive looked embarrassed and apologized to Xiaotian: "Little incompetence, this glass blowing job is really not easy to do!" During the days when the big boss was away, the small ones didn't dare to be lazy, and tried to blow every day, but only a few vases were blown out, and the shape was slightly more complicated, or a little bigger, and they were blown out!

It's the flat glass that makes the mirror, it's better, and a lot has been done in this time, but it can't be made if it's bigger! It always crumbles when it anneals! ”

Yu Xiaotian looked at a few glass vases that they blew into, these vases are not large, and the walls are relatively thick, the shape is so-so, but not delicate enough, but in this era, it is relatively good, which shows that these craftsmen have really thought of a way, and they have been trying to explore for a long time.

Blowing glass is not something that anyone can do, you have to have a large lung capacity, you have to be fast, you have to have some artistic attainments, and you have to have a rough shape in your head.

These workers are all novices, and they have never even seen such a thing as glass before, and now let them do the work of blowing glass, it is clear that they are chasing ducks to the shelves, and it is understandable that they can't do it well in a short time.

So Yu Xiaotian didn't get angry, but praised the senior management and the workers here a few words, and encouraged them.

Looking at these glass products, Yu Xiaotian sighed, and turned to the senior management and said: "I forgot one thing before leaving, in fact, you don't necessarily have to use the method of blowing to make glass, and there is another way that is more convenient, but I forgot to tell you at the beginning!"

I'm here today to tell you this method, and in the future, we can try to use the method of molding to create some simple glass products! ”

"Molded?" The executives looked puzzled.

Yu Xiaotian saw that he didn't understand very well, so he explained: "Molding is to make a mold with copper and iron first, and then put the molten glass in, and the female mold and the male mold are squeezed against each other, and the molten glass is extruded!" This method is very simple, just let Tiezuo help you make some molds, and you can produce all kinds of glassware in large quantities in the future! ”

The executive understood it now, and slapped his head and shouted, "God, I see!" How did the big boss come up with it, and why didn't we guys think of it? That's a great idea! If you can make a few sets of molds, one will come out as soon as you press it in the future, haluha! Big boss, you are really a master! ”

Yu Xiaotian looked at the overjoyed executives, and was a little proud, he, a pirate, is now stealing the research results of future generations at every turn, and taking them for himself, I don't know how many people's jobs will be smashed in the future! But now he won't tell people that this is the result of his piracy and stealing the wisdom of others, so he is very proud to accept the compliments of the executives.

As for the production of glass mirrors, the production is also continuing steadily, and the made glass plates are sent to another shed, placed in iron plates, just when the glass plates are stuck, and after sewing the side seams, the workers spread a piece of tin foil on the glass plate, flatten the tin foil to make it tightly bound to the glass, leaving no air, and then pour the ready-made mercury into the trough and spread over the whole glass.

Then they waited for the mercury and tin foil to react, which was a long process and took at least half a month, so for this reason, they could only help them build a lot of grooves made of iron plates, otherwise they would not be able to make the glass mirrors in the glass yard form a continuous production.

When Yu Xiaotian came back this time, dozens of glass mirrors have been made here, this kind of glass mirror made of mercury and tin foil can't be compared with the glass mirror of later generations in terms of quality, and the clarity and reflection are not as good as the glass mirrors of later generations, but in this era, this thing is already a high-tech product, so far, only Tunisian glass craftsmen and French glass craftsmen will do this, and they are also strictly technical blockade, Yu Xiaotian's current glass mirror is definitely the third in this world. So there is no worry about no sales at all.

Yu Xiaotian just took a brief look at the production of the glass yard, and told the senior executives about the molding method, as for the molds they wanted to do, Yu Xiaotian simply came to a big, and let them toss.

After all, there is a big difference between people's appreciation and later generations, if he interferes in everything, the things he makes, not necessarily people of this era will like it, so if he has time, he can give advice, but the main design is better to leave to the craftsmen of this era to ponder.

In addition to the glass field, Yu Xiaotian went straight to the east shore with his personal guards, because in order to avoid burning seaweed to obtain seagrass and wood ash, the smoke and dust were too large and affected the living area, so the burning of seagrass was placed on the east shore of the island, and there was the most seagrass there, which was more suitable for this.

Yu Xiaotian is riding a horse a little better now, and he is no longer as nervous as he was when he rode a horse for the first time, but his level is limited to when the horse is jogging, and it will not fall, if he is allowed to ride this thing into battle to kill the enemy, it is estimated that he will be able to kill himself himself, and no one will have to do it!

After arriving at the place, Yu Xiaotian saw that the seagrass was spread out and dried everywhere on the beach, some people were still fishing for seagrass on the beach, while some people were constantly checking the seagrass that had been fished ashore, pulling the dried seagrass to several fixed places and throwing it into the fire to light it.

The smell of burning seaweed is very unpleasant, and there is a strong fishy smell in the air, but for the people who live by the sea, it is nothing, and it does not affect the people who work here in the slightest.

There is a cave on the east side of the island, the burned grass and wood ashes are packed into large wooden barrels and tamped, and carried to the cave for storage, these workers are actually the families of the fishermen on the island, mainly women and children, they usually can't go out to sea with the boat to fish, when the family goes out to fish, they have nothing to do, they can only serve some thin fields, grow some vegetables or simple grain, subsidize the family;

Now that they have the matter of burning seaweed and collecting plant ash, they are called in, and use their free time to do some work, and the sea wolf gives them a little money, although the labor cost is very low, but for them there is another way to subsidize the family, so the families of the fishermen on the island are still happy to do these things.

Yu Xiaotian took a look at the cave, there was indeed a lot of plant ash piled up in it, this thing was the raw material he used to replace the soda ash, others couldn't look at it, but it was a good thing for him.
