The reason why Arthur didn’t attend serf’s “welcome meeting” was because he had more important things to do.

Over the past few months, he has been sending people to find various caves in the green peak mountain range with suitable conditions. Looking for caves, it is natural that he is not going to be a caveman, but that he intends to make nitrate.

To be precise, it is intended to boil the cave!

Nitra, also known as Potassium Nitrate, is commonly known as soil nitrate, fire nitrate, salt nitrate, etc.

In China, the production of nitrate was started more than 2000 years ago, and until the 6th and 70th generations of the last century, there were many people in the countryside of China who were nitrites.

The most well-known use of nitrate is to produce black powder and fireworks.

Black gunpowder is one of Huaxia’s four great inventions, and its formula is well known: mononitrogen 4 sulfur 2 charcoal.

This is chemistry knowledge in junior high school.

But in addition to being used to make black powder and to produce explosive firecrackers, the use of nitrate is actually quite extensive.

For example, he can also be used as a medicine, known as thenardite. Arthur vaguely remembers that the junior high school chemistry teacher said it can cure bloating and dry stools, and can’t pull out the symptoms of feces.

In addition to medicinal use, nitrate can also be used in industrial production, such as dyes, glass, matches, and kneading fur.

In addition to industrial uses, nitrate can also be used in food processing, such as as a hair coloring agent or cured meat products, to enhance color and flavor while preventing spoilage. Of course, this thing is toxic, and it must be strictly managed when used as a food additive.

In addition to the above, the most widely used nitrate is actually agriculture. It is a chlorine-free potassium-nitrogen compound fertilizer. It has high solubility, can be quickly absorbed by crops, and has no chemical residues. It will not compact the land.

And this is exactly the main purpose of Arthur’s cooking.

Agriculture is always the most basic and important industry. It not only provides people with subsistence guarantee, but also the first condition for all production.

In the current Windward Fort, although after some agricultural reforms, the grain has become self-sufficient and there is even some surplus grain, but if you want to develop some light industry, this grain is far from enough.

For example, the brewing industry that Arthur has always wanted.

Therefore, while expanding the area of ​​cultivated land, we must strive to increase grain output.

The reason why China’s grain output is several times that of this World is the most important reason is the use of seeds and fertilizers.

seed……

So I had to work hard on fertilizers.

After several months of searching, within the green peak mountain range, nearly 20 caves were found suitable for cooking caves.

These caves, of which the overwhelming majority, are small caves less than half a mile deep. Although these small caves can also be used to cook nitrate, the yield is not too high.

Fortunately, in addition to these small caves, there are 6 larger caves, of which 2 are caves. The person in charge of exploring the cave has not yet figured out how deep it is. I only said that I burned 2 torch and could not go. To the end.

Cave nitrate is naturally boiled in the cave.

After finding these two large caves, Arthur named them Cave No. 2 and Cave No. 2, and then let people cut the wood to open the road, and vigorously carried out the nitrification campaign in Cave No. 1.

To boil a hole in the nitrate, we must first dig a nitrate pit. As long as it is easy to operate, the bigger the pit, the better.

Because boiling nitrate is a tedious process, the larger the digging of the nitrate pit, the more output can be obtained in a single tedious process of making nitrate.

Now the pit in front of Arthur is a pit more than 3 meters in diameter and 2 meters deep.

After the pit was dug, the soil on the pit wall and the bottom of the pit was tamped. As for the degree of tamping, Arthur’s requirement for the nitrate builders was: no more tamping!

After the pit is ready, a small hole is then pierced at the bottom of the pit, and a small pit is dug underneath. A container is placed in the pit to receive the nitrate water seeping from above.

It takes a lot of effort to build such a funnel-shaped nitrate pit. Seventy-eighty famous nitrate workers spent more than a month, but only eleven such pits were built on the right side of the cave. Pit.

After the pit is prepared, it is ready to prepare nitrate.

Nitrite will exist in many places, such as cottages, huts for pigs, cattle, sheep and livestock, old corners of courtyards, rock caves, and other places that are not easily washed by water.

The amount of nitrite in cottages and other places is too small, and it is inconvenient to collect, but Arthur has also let farmers be responsible for collection and storage, and every year Windward Fort agrees to purchase. Can also be regarded as income generation for farmers.

Boiling nitrate, the main source of nitrate, is naturally nitrate in the cave.

The quality of nitrite varies greatly according to the amount of nitrate. According to Arthur’s memory, the best nitrate tastes in the mouth, and there will be a spicy taste, and the worst nitrate will be slightly sweet.

This was what he heard from a female guide when he traveled to a cave in his last life, and he also tasted a little bit of earth.

After repeated attempts by Arthur and the others, it was concluded that the depth of excavation in the No. 1 cave can be at least half a meter.

Before pouring the nitrate into the pit, it is necessary to lay a layer of hay on the bottom of the pit. After pouring the nitrate, the nitrate should be continuously tamped. Similarly, the tighter the better.

Because of the iron ore mine, Arthur, rich and imposing, let the forging factory create a huge iron funnel that can directly cover the pit.

The purpose of this is to prevent the water from leaking to all around when spraying nitrate. 2 It is convenient for repeated use.

After the nitrite is filled, water will be added to the pool. The added water is preferably stagnant water in the cave.

The process of water infiltration from top to bottom is nitrating.

Because it was the first time to make nitrate, Arthur only used one pit for the purpose of the experiment.

The nitrate pit that was being sprayed with nitrate was injected with water 4 days ago. Because the nitrite was compacted very tightly, no nitrate leaked into the large wooden basin below until early this morning.

As the nitrate continued to seep out, Thorne and the others could not help sniffing their noses, they found that the strange smell in the air seemed to be getting stronger and stronger.

Leaning next to Arthur, Thorne said worriedly: “Adult, this smells a little strange, smells more choking than the urine of cattle and horses, could it be a problem?”

Arthur sat waiting, smiling, the choking smell in the air was indeed unpleasant, but he enjoyed it at the moment.

“Relax, this is the taste!” He said excitedly, “And the more choking the better, it means that the concentration of nitrate we get is high enough!”

At this point in the experiment, Arthur’s heart was mostly stable. As long as a high concentration of nitrate can be obtained, the following process is nothing more than a distillation and purification step.

Even if there is no way to get high-purity Potassium Nitrate, but it is more than enough for fertilizing crops.

After estimating that enough nitrate water had oozed out for an experiment, Arthur had someone pour it into a large black pot on the left side of the cave and set the fire on to start cooking.
