As early as the time of Miaojiazhuang, Zhao Xin had already begun to study this aspect, but unfortunately because of the imminent war, he had no way to directly build a large-scale cave and specialize in firing glass.

Because compared to glass, cement and brick kilns, the requirements are not high, but they are more effective for war.

This point was also proved in the subsequent Western Xia Campaign, if there was no fortress, Liao Xingzong would be violent, even if Han Qi had a force like a longbow to attack, perhaps in terms of combat effectiveness, under the premise of being similar to Liao Xingzong's heavy cavalry, he also needed to pay huge casualties to be able to force back the heavy cavalry of Liao, instead of now, it was easy to fight with Liao Xingzong, and even in the end, he obtained the entire process of the contract.

When I arrived at the Daimyo's Mansion, all the focus was on steel, which was more important than glass, and in fact, steel also played a huge role, not only gave the navy a huge source of finance, but the current income alone was as high as tens of millions of dollars per year on steel, and under such a premise, this income was enough to offset everything.

That is, when it comes to the Dinghai Navy, some of them are stabilized, which is put on the glass, especially now, the window paper is becoming more and more unsuitable for the development of the Dinghai Navy, and the importance of glass is highlighted.

However, this glass did not go well, unlike the steel mill relying on the help of the card system, as well as the tradition before the Great Song Dynasty, glass is a new beginning.

There are many blacksmiths' secret recipes in the steel factory, and a large part of these secret recipes overlap and are useless, but the simple discovery of more than a dozen catalysts has greatly promoted the development of the steel industry, not to mention, there are also steel talents like Niu Dali, who have not been encountered in a century.

The entire Northern Song Dynasty is so huge, there should be many similar talents, and there should also be a genius in glass, but they did not appear in front of Zhao Xin, and even in a sense, under the base of the entire Northern Song Dynasty, this number is even more terrifying.

Now the Dingjun, in a sense, does not even know a little about glass, relying on the original pottery, pottery and glass, these are two completely different fields. These people don't have the ability to draw inferences from one another, at most, to improve in experiments.

Zhao Xin can't change the situation of these researchers, so he can only rely on improving in other aspects, for example, more suitable experimental processes, for example, more perfect materials, adding these together to form the periphery of the experiment, and not affecting the experimental data itself.

Zhao Xin built a large number of small caves to control the cost, and the materials were also strictly controlled each time, and a series of records were made.

Scientific recording methods are the key to perfecting the final experimental process, and in this sense, glass should not be a problem.

Zhao Xin couldn't have the luxury of expecting it, just like those passaged texts, he quickly obtained the glass, but he didn't expect that this process would be so difficult, unimaginably difficult. 、

The reason why basic disciplines are terrible is because of the huge cost, and in the absence of a clear formula, it needs to be studied slowly by exhaustive methods.

At the beginning, Zhao Xin only built 3 groups of people, and at the beginning, he didn't pay much attention to it, that is, when the demand for glass became more and more important, he began to increase the process of this demand.

Now there are at least 100 groups of people, most of these people, have little understanding of glass, because the Dinghai Navy finally collected talents in the field of countermeasures glass, and finally there were only 7 people, these people were divided into 7 groups, each group is with elite soldiers, gathered together, research, they are also the most important part.

It is a pity that these people have no record of these experiments of the navy, and even with the assistance of some people, they have made great efforts, and in such a process, it is difficult to move forward.

To a certain extent, these people are only an auxiliary role, and those who have really made breakthroughs are still the original, some people who have made breakthroughs in firing bricks or porcelain, and are familiar with the entire process of Dinghai research.

Of course, Zhao Xin knows that these processes cannot be rushed, but in a sense, glass has become a process of huge investment in the navy.

Of course, in more than half a year, they have also made some progress, at least, for the production method of glaze has made great progress, and even produced at least 20 kinds of cheap and beautiful glaze formulas, simply in the field of glaze, has a strong strength.

In a sense, there are some handicrafts whose value is no less than that of treasures.

The reason why glass is called colored glass, a key reason, he is a substitute for jade, such a thing, to a large extent imitates jade, because these people are more familiar with this formula, so, to a large extent, it is a big detour, there are not many transparent glass, but there are a lot about glass.

In a sense, as long as this is vigorously developed, it can be regarded as a good direction, although Zhao Xin is not there, but those who almost regard interests as everything in the middle of the navy, or choose some more suitable things from the middle, and then make different crafts.

Compared with jade, the color of glass is very strong, and to a certain extent, the hardness of items made of glass is very strong, and the hardness of glass, even to a certain extent, is similar to jade. You must know that the diamond that cut glass in later generations is a natural mineral that reaches 10 in terms of hardness, and few of the entire synthetic items can catch up with his hardness.

Of course, a huge part of the glass knife is also a synthetic diamond, otherwise, it would not be so cheap.

But there is still a long way to go from being transparent, you must know that the best is just a translucent, equivalent to a more translucent jade, if this is made into a glass window, it is almost a ground glass, and the light transmittance has been improved too much compared to paper.

If you have never seen a glass window in the 21st century, you may think that this is a very good glass window, but Zhao Xin, who has really seen glass in the 21st century, knows very well that this is not real transparent glass.

Transparent glass, divided into many kinds, Zhao Xin didn't think about it, directly made the terrible optical glass, the kind that does not have any problems at all, can be used in telescopes and optical lenses, the kind that even in the 21st century, it is also some top-secret things, ordinary countries, even if they invest a lot of money, may not be able to research it, ordinary ordinary glass is almost the same, this is already the limit

Although Zhao Xin said that he was very anxious, he also knew that this thing was in a hurry, especially the more basic the research, the more so, after the previous simple anxiety, and even some investment regardless of the cost, Zhao Xin also woke up from the anxiety, and he relaxed, because the end of the year was coming.

Perhaps it was the relationship between the unintentional willows, the real anxious waiting, more than 20 different glass formulas, did not form a colorless glass, but after putting it down, in less than 10 days, there was good news, one of the groups finally succeeded in making a transparent glass formula.

Of course, Zhao Xin knows how important this transparent glass formula is, and it can be said unceremoniously that it represents a leap in technology, and he used the card system to record this glass formula almost immediately.

However, what excites him is that this group, a scientific team, has made a perfect record of the entire process of the experiment, and after less than 2 hours, the process is reproduced.

This is completely different from the study of ancient China, it can be said unceremoniously that those studies of ancient China are more about luck, when luck encounters, you can make it, to reproduce, sorry, it is very difficult, that is, in the stumbling again and again, and finally come to this process, sometimes, a lot of useless work.

Now, Zhao Xin has popularized this scientific way of recording in Dinghai, each time, how many things have been invested, which minerals, have been clearly recorded, and after the reappearance of glass, the next step is to analyze this formula.

Of course, Zhao Xin knew that there were many formulas for the whole glass, which could be said to be hundreds or thousands, but Zhao Xin asked for only one, and then adjusted according to this method, reduced the cost, and increased his performance, and the entire more than 40 teams went all out to study this, and all the previous processes were stopped.

It seems that this is a kind of seedling promotion, but in fact, this kind of seedling promotion is very useful, in just half a month, about the transparent glass formula, at least hundreds of kinds of research have been studied, and even some very outstanding performance of the glass have also been studied, Dingjun, has the possibility of making glass.

After that, it is a process from laboratory production to industrialization, compared to the previous one, this is easier, to a certain extent, at the same time in the laboratory, industrial production is also continuing, under unremitting efforts, about the end of December, the first transparent glass products, the successful appearance, which also represents the glass really into the industrial system of the Dinghai Navy.

Finally found a suitable formula, and then there is the most famous bubble problem, which is not a problem in the glass, and the bubbles in it will also form a special pattern, making this glass even better.

But in transparent glass, this is very problematic, which also restricts the size of the glass, but this is easy to solve for Zhao Xin.

Bubbles are formed in the process of making glass, without the gradual condensation of the liquid and the gas enclosed into it.

Use a glass rod to stir in the liquid, so that a large amount of gas produced by the reaction is released in the reaction, and then there are no bubbles, or the bubbles are very small enough to affect the problem.

As for the process of silver plating, it is also being explored, and now, it is gradually groping, and there are some clues.

But now, after the large-scale flat glass that has been produced, some glass applications have also begun to show, for example, glass windows, which have changed the original paper-paste window screen, with higher brightness and better thermal performance, which is more suitable for places like Dinghai where the sea breeze is relatively large.

Similarly, glass greenhouses are beginning to appear.

This move has completely changed the original balance, the land area of the Dinghai Navy is limited, the industrial land and various main residential land, is the most, the emergence of these glass greenhouses, but also greatly enriched the market of the Dingjun.

The emergence of glassware, for the newly established laboratory, is the best thing, some things, the reaction is very intuitive, there is no transparent container, it is difficult to see the whole reaction process, which is not conducive to the experiment, the first batch of high-quality, precision glassware, has become the standard equipment of the laboratory, greatly improving the efficiency of research.

In this way, through adjustment and improvement, unconsciously, it has reached the end of the year, although because of the relationship of the ironworks, Zhao Xin stopped the footsteps of going to Bianliang, but he has always remembered this thing in his heart, the railway, for the promotion of the entire Northern Song Dynasty, can be said to be very important, now, the glass has completed the production, the mirror is almost completed, maybe not the best formula, but to a certain extent, it is already acceptable, simple mirror, has been produced in small batches.

These can already be used as a new commodity of the Dinghai Navy, put into the real Dinghai Navy's commodities, create profits for the Dinghai Navy, and the development of the entire Dinghai Navy has also entered a benign track

Zhao Xin once again prepared for the trip, compared with the formation 4 months ago, this time, he was more prepared.

Originally, 30 thousand stone ships have now been upgraded to 100, and even Bianliang needs to prepare a special wharf to dock these ships.

This time, Zhao Xin also used this as a way to show the power of the Dinghai Navy, and he brought almost all the new products, including, of course, glass and mirrors, which had not yet been finally expanded, as important commodities.

Compared with the previous rush to travel for steel and rail, this time, he was more prepared, not only carrying a large amount of goods, but also a lot of money, this time, it was Zhao Xin's real stage to show his strength.
