Because of the imperial examination, the Confucian classics occupy an overwhelming position in the study of this era, and as for other disciplines, including arithmetic, they are all electives.

Zhao Luan's learning is no exception, he also specializes in Confucianism, and he is familiar with the classics of Confucianism, so he will come as soon as he opens his mouth. It's not that I haven't learned arithmetic, but arithmetic is a small way, and Zhao Lian is only dabbling in it slightly. And there are many restrictions on the royal family, such as alchemy, which belongs to the restricted level, Zhao Lian has been instilled since he was a child, and most of the monks are first-class liars, so Zhao Lian not only has never dabbled in it, but also has a stubborn prejudice against alchemy.

What elements, atoms and molecules, Zhao Lian naturally does not understand, and the science of chemistry is by no means three or two days to make people enter the room. In short, in Zhao Luan's eyes, no matter how you look at the methods used by Mao Geng, they are like alchemy, and Mao Geng is like a Taoist warlock. However, Mao Geng claimed to have a supreme master from the beginning, and it is not surprising that he knows alchemy, but it is rare that Mao Geng is willing to pass on the secret of his master to himself.

However, Zhao Lian has a deep-rooted resistance to Taoist alchemy, and subconsciously disdains the left side door, although Mao Geng explained to Zhao Lian that this is science, specifically a discipline of science - chemistry, although its end is alchemy.

But Zhao Lian just can't afford to look down on this science, which is also known as scientific chemistry.

It can only be said that Zhao Lian is a little paranoid, compared with indulging in steam power, Zhao Lian's interest in the subject of chemistry is limited.

The extraction of vinegar stone to make soda ash belonged to the soil method in the twentieth century, and only in the era of the Great / Leap Forward would this high-energy-consuming method be used to do it quickly, but eight hundred years ago, it was an advanced technology. It can be said that Mao Geng won the crown jewel of chemistry in this era, but it is a pity that Zhao Lu can't appreciate it, which is a bit regrettable.

Soda ash is the main raw material for making glass, and can also be used to make caustic soda, which is an important raw material for making soap and paper. The production of soda ash means that the two alkalis in the "three acids and two alkalis" have been settled.

Firing glass consumes soda ash very much, and every 1,000 catties of glass produced, 200 catties of soda ash must be consumed. At the time of Xinhua, the firing glass was a plant alkali made from the filtrate of plant ash, the output was limited, and the second was difficult to purify, so Mao Geng was looking forward to the day of industrial production of soda ash from the first day of successful glass firing.

Extracting vinegar to produce soda ash, of course, is not as good as the Lubland method in terms of output, but it has its advantages in the purity of soda ash, and in order to make gunpowder and activated carbon, it has been burning a large amount of charcoal, if you do not recycle and extract vinegar, it is a waste. As for another raw material, miscanthus nitrate, China's miscanthus nitrate reserves are the world's first, and the introduction of investment in Sichuan and Hengyang, Hunan Province in later generations often unequivocally declares: the local miscanthus nitrate reserves reach n billion tons, Yunyun, so the source of miscanthus nitrate is not to worry at all.

The salt wells in Hengzhou and Sichuan produce a large amount of miscanthus salt, and the by-products obtained from this mining of rock salt are sold at a very low price, so the cost of purchasing miscanthus nitrate is almost negligible, but the purification of miscanthus nitrate is a bit troublesome.

Of course, the vinegar stone method of soda ash method is limited by the limited collection of vinegar stone in the charcoal kiln, and only eight kilograms of vinegar can be collected by burning 100 catties of charcoal. Therefore, Mao Geng did not only keep the meaning of vinegar stone alkali method, and Lu Blan's alkali method was actually also producing.

In his previous life, his distant uncle introduced the advantages and disadvantages of the vinegar stone method and the Lu Bran method, of course, the main purpose was to praise himself for the vinegar stone method he made, for example, he proudly claimed that the vinegar stone produces soda ash, and the sulfate of the soda ash produced is almost negligible, in addition to the high purity of soda ash, the additional products are propyl/ketone. Of course, all comparisons are based on the Lü Blanc method, and Mao Geng also heard of the famous Lü Blanc method.

It is said that in 1775, the French Academy of Sciences made a huge bounty to openly solicit practical methods for making soda ash. As we all know, Lü Bran made the famous Lü Bran alkali method, the first step of this alkali production method is to use sulfuric acid and salt reaction to prepare miscanthus nitrate, and then mix with limestone, charcoal into the furnace calcination, soda ash can be obtained.

Very fortunately, the miscanthus of the Great Song Dynasty is dug and dug in the ground casually, especially in Hengzhou, digging down twenty or thirty meters is the miscanthus nitrate, which can be called a lot of quantity and low price, this time, it directly omits the step of making sulfuric acid. However, what bothers Mao Geng is that the purity of the alkali method made by Lu Bran has not been very good, so at present, it has to rely more on vinegar stone to make alkali. It seems that we have to imitate the French way of doing it, and come to a heavy reward and incentive, maybe someone will try their best to find the trick.

But no matter what, the "two alkalis" chemical industry is beginning to take shape.

Zhao Lian not only watched the production of soda ash, but also the process of making caustic soda from soda ash. Caustic soda is prepared by using vinegar stone as raw material, heating water to make a saturated solution of soda ash, and then adding excess lime milk to prepare caustic soda. However, Zhao Lu just looked at it and didn't ask any questions, Mao Geng originally wanted to explain to him that hot water can improve the solubility of soda ash in water, etc., but Zhao Lu really didn't have much interest in chemistry.

"Mao Geng, these smoke, gas, powder, water, liquid, ash, I see that my head is big, these alchemy techniques------ oh, they are chemical techniques, as long as you understand it, I won't mix it."

Mao Geng shook his head!

All right! It's okay if you don't applaud my smugness, but you have to regard dignified chemistry as alchemy, how can this be embarrassing!

"Mao Geng, I think clearly, I'd better go and get involved in shipbuilding."

Regarding Zhao Luan's request to participate in shipbuilding, Mao Geng expressed his understanding, of course, if you want to grasp it, you must grasp big projects, such as large projects related to the national economy and people's livelihood. Before Zhao Luan focused on planting sweet potatoes, although so far Zhao Luan has always been concerned about the growth of sweet potatoes, but one does not need him to water, two do not need him to water fertilizer, what really to care about is just how good the sweet potato harvest can be in a few days, which in the final analysis is a correct attitude that should be taken as the successor of the royal family in the era of grain.

Zhao Lu is young, he is the age of great ideals, here in Mao Geng, to mix with other things, it seems that it is not in line with the identity of the prince of other countries. However, it has always been regarded by Mao Geng as the shipbuilding industry representing the highest level of manufacturing, and under the guidance of the respected Guogong, whether in politics or in satisfying Zhao Luan's curiosity, there is no other choice.

"Whatever Guogong wants to do, I fully support it."

As long as he doesn't make gunpowder, mines, or go around the boiler, Mao Geng feels that Zhao Lu can do anything else, and he can do it.

But Zhao Lu's following words surprised Mao Geng:

"Mao Geng, the ship built by Jiang Zhiang seems to be too small, if you want me to see, if you want to build a big one. However, I wonder if the ship can also use steam power when the ship is too big? I mean, can steam power push a big ship like a small boat? ”

Mao Geng knew that Zhao Lian had seen a whaling ship that Jiang Zhiang was building, and the reason why this whaling ship used a steam turbine as power was for testing on the one hand, and on the other hand, it was also for the needs of whaling.

"Guogong, of course, steam power can also be used on big ships, but it can't reach such a high power for the time being, this has to be done slowly, maybe in a year, a steam engine that can drive a big ship can be built."

"I heard Jiang Zhiang say that the ship should be equipped with cannons, what is a cannon?"

Even this knows! All right! It seems that there is no secret about Zhao Lu.

"Cannons, I've built two and tried them, and there are still some problems, but in two days, Guogong will be able to see the power of the cannon."

Speaking of cannons, in fact, Mao Geng's most urgent thing is the whaling cannon. Mao Geng felt that since he built a whaling ship, he had to build a weapon that matched the whaling ship. In fact, the cannon has been successfully tested some time ago, but it has just begun to be built, there are many problems, and it must be overjoyed to put it in others, but in Mao Geng's eyes, the casting technology of the cannon is still a bit slag and needs to be improved.

The whaling cannon is more complicated, and it is a bit difficult to shoot the whaling gun out with the explosive force of gunpowder, and it also needs to be accurate one by one.

For the cannon, Han Yanxuan only heard that Mao Geng was trying to make an explosive weapon, but Han Yanxuan has been very busy recently, and Mao Geng has too many new gadgets, and he is a little dizzying, so Mao Geng did not invite Han Yanxuan to see it, and Han Yanxuan did not take the initiative to ask onlookers.

Of course, this is also because the caliber of the cannon that Mao Geng tried to produce is a bit pitiful, it is only a caliber of forty millimeters, and the movement is not big enough, for the time being, several disciples of Mao Geng who are responsible for the trial production of the cannon know the detailed situation. Although they were very encouraged after the successful test launch, they felt that Mao Geng didn't seem to be very satisfied, as if they were still a little unable to take a shot.

And Han Yanxuan was indeed very busy during this period of time, because Mao Geng pushed most of the product sales to Han Yanzhou. Anyway, Mao Geng himself is not responsible for sales, except for the bulk procurement of Huaxi Construction Company, here in Kaohsiung, the sales are entrusted to Han Yanxuan, and as for Lin'an Wenyuan, he is also responsible for part of the sales, but the sales power is mainly in the hands of Han Yanxuan.

In other words, Han Yanzhou and Wen Yuan are the two regional distributors of Kaohsiung products, and Han Yanzhou holds most of the sales rights of cement and timetables.

In view of the fact that all the new industrial products produced in Kaohsiung are in a state of strict supply and demand, the newly built four-star inn in Kaohsiung has slowly become lively for some time, and the merchants who have crossed the Taiwan Strait to purchase goods in Kaohsiung have begun to show their talents, and even do not hesitate to go through the back door of various ways, the purpose is to be able to batch the goods.
