[If you travel back in time, for safety, the preferred crafting item is not the finished product, but the kind of almost universal raw material, which is soda ash.

It is a panacea in industry, with it, you can not only make soap, but also make glass ceramics, but also can be used for pharmaceuticals, testing tools and so on.

However, it should be noted that although soda ash is called soda, it is not the same thing as the baking soda we commonly use.

So how do you get soda ash? The best thing to do is to find a alkaline lake to extract, and if you can't find it, you have to make it yourself.

First, the refined salt is added to water to make saturated brine, and then ammonia is added to make it become ammonia brine, and then the calcined limestone is used to obtain carbon dioxide, which is added to the ammonia brine, and then the impurities are filtered, and then calcined at high temperature, and the last item left is soda ash.

Of course, if you are not a fish that has slipped through the net of nine years of compulsory education, you will definitely be able to remember these steps, after all, we learned them when we were in school.

And most of the things used in the whole process can be easily found in ancient times, and the only thing that gives us a headache is ammonia.

However, there is also a way to obtain it, and that is to use a sealed jar to distill the gas collected in the urine, which is ammonia.

Although this method smells a bit good, the good thing is that it can be reused.

The method of recycling is to filter the impurities of the used urine, and then add hydrated lime and distill it to collect it back, so that we can make alkali again. 】

The people of this dynasty were very surprised when they saw the video on the canopy.

They had been hoping that the canopy would give them a way to make alkali, and now they finally got their wish.

And compared to the comments in the previous video, they couldn't understand it at all, and this video also made them understand how to make alkali better.

With such detailed steps on the canopy, even a fool can make alkali.

At the same time, they are rejoicing that the method of how to make salt has already appeared on the canopy of the stars, so that the price of salt in their era continues to fall, and it also gives them more possibilities.

So countless people from various dynasties began to act, and there was no alkaline water lake in the place where they lived, so they could only use the second method.

They bought some salt and limestone, collected some urine, custom-made some sealed jars, and started their own soda business.

This also led to the people of various dynasties, filled with the smell of urine, but when they saw the alkali they made, they were very happy.

And the alkali they made was then bought by the people who made soap, and the silver of the white flowers fell into their hands.

This made them very happy, and they were worried about the sales of this alkali, but they didn't expect to be approached.

They are full of expectations for their future life and believe that their lives are getting better and better.

Qin Dynasty.

Qin Shi Huang saw the method of making alkali on the canopy, and he immediately issued an order to the children of the Mo family, asking them to quickly learn the method on the canopy to make alkali.

After all, the effect of these alkalis is clearly stated in the canopy, not only can be made into soap, but also can be made into other things.

After the Mo family children received the order, they were very excited.

This time it wasn't like the excavator, they didn't even know how it worked.

At that time, they were very worried, for fear that Qin Shi Huang would be angry with their inaction and convict them all of them collectively.

Although they didn't know the specific principle this time, the canopy gave them the method of making alkali, and all they needed was to follow the steps to implement and make it.

So the children of the Mo family began to act, firing all kinds of tanks for making alkali, and brought raw materials for making alkali in other departments of the imperial court.

Then, in the following time, they began step by step according to the method on the canopy, and finally after everything was done, they made the alkali mentioned in the canopy.

After they made them, they gave them to Qin Shi Huang to see.

Qin Shi Huang saw the alkali sent by the children of the Mo family, and he fell into deep thought.

Compared with the various methods of using this alkali in the canopy, the only thing they can apply is to make soap.

The alkali production method given on the canopy has a very high daily output, and the production of soap is completely unable to keep up.

As for the other methods, they need to experiment one after another.

The children of the Mo family believe that in the near future, they will definitely be able to find a market for the use of alkali.

With the production of soda ash by the children of the Mo family, the plant ash used in the soap became soda ash, and the performance of the soap made was greatly improved.

This made many people very happy in their hearts.

After all, the soap they used to buy at the imperial court was not as good as the soap made from soda ash, and the money required for both soaps was the same.

They were curious, would the people be as happy as they were when they knew how to make alkali?

At the same time, the children of the Mo family are also studying the specific role of this alkali, hoping that the alkali produced can be carried forward.

However, before they could act, the children of the Mo family were sent to the cold palace, after all, Qin Shi Huang had already obtained his own goal, how could it be easy for them again.

Han dynasty.

Emperor Wu of the Han Dynasty, Liu Che, saw the video on the canopy and watched his predecessors make it step by step, he felt very magical.

Such a magical picture reminded him of those warlocks, and I am afraid that only they have such skills.

It's a pity that those warlocks don't know the principle like later generations, and the magical spells they know are just knowledge passed down from their ancestors, not magical spells.

And now that there is alkali, Emperor Wu of the Han Dynasty Liu Che wants to know more, what is the steamed bun? Why does it become sweet and white when you put it in alkali?

Three Kingdoms period.

Zhuge Liang looked at the sweet and white steamed buns after putting in alkaline noodles, and he was very happy.

He believes that in the near future, this steamed bun will definitely become a staple food for the people.

At the same time, he hopes that there will be more videos like this on the canopy, which will also change the lives of the people of Shu.

After Cao Cao and Sun Quan saw the video on the canopy, they also made alkali, but when they saw that alkali could make white and sweet steamed buns, they were very unhappy.

After all, Zhuge Liang is just a head above them in "Romance of the Three Kingdoms", why is he still like this in reality?

Whoever is put on it like this, I believe that everyone is unhappy in their hearts.

But thinking that this is the people's demand after all, they didn't stop the people from making it.

Only the salt they buy is regulated, for fear that these people will hoard salt and leave those who really need it nowhere to buy it.
