The method of making soap is really simple.

The raw materials needed are easy to find.

Low-grade soap can be made from potassium salts and grease in plant ash.

For better soaps, a high concentration of caustic soda is required.

After testing, the washing effect of the "fragrant soda" provided by Liu Ruyan is better than that made of plant ash, but it is lower than that made of caustic soda.

Because, in later generations, the soap made of caustic soda, Wang Li used many pieces!

It's easy to compare the results!

"Factory, lime, baking soda and lard can really be made into soap?"

"I guess it's okay!"

Wang Li stirred the lime water in the tank, and some of his confidence was insufficient.

Because, there is no caustic soda in this era!

Where did those time-travelers in novels or TV series get caustic soda?

Isn't this fooling?

However, with my knowledge of scum, it is not too difficult to make caustic soda!

Caustic soda, isn't it sodium hydroxide!

Baking soda is sodium carbonate!

Hydrated lime dissolves in water, isn't it calcium hydroxide!

Soda and lime water, the precipitate is calcium carbonate, and the rest is sodium hydroxide solution!

Then evaporate it and increase the concentration!

That's the theory!

However, in practice, why is it different?

After five days, two attempts, all failed!

Hell yes!

The sediment has been filtered out!

What is left in the water should be caustic soda!

But...... After heating the water slightly and slowly evaporating it, what is left is powder?

It's really powder!

This is clearly soda!

Not caustic soda!

The real caustic soda, Wang Li has seen it!

Lumpy or flaky to absorb moisture from the air!

It's not the same as powdered soda!

Depend on!

Could it be that the textbook is wrong?

But how could something as simple go wrong?

Could it be that my character is not good?

Could it be that I am not only a scumbag of history and geography, but also a scumbag of chemistry?

Depend on! How did I never find out?

But, no matter how scummy I am, I can't be wrong about such a simple thing!

So, why can someone else's traverser make it?

No way! Be patient!

Failure is success, success!

If you can't do it three times, do it thirty times, three hundred times!

Two taels of silver a piece!

Compared to growing grain and raising pigs, making soap is faster to make money!

As long as it can be made, it is silver!

……

One month!

More than a dozen trials in a row!

Finally......

Give up!

Same result every time!

It's really baking soda!

Not caustic soda!

Because, with a few bowls of soda mixed with powder, the thirst-quenching effect is not bad!

It's exactly the same as water made directly from soda!

"Factory, don't you try it again?"

"Don't try!"

Wang Li gave up completely, and said weakly: "Jingshi's "Hexianglou" and "Hua Hanchong", they can sell two taels of silver each, it is people's ability!" ”

With that, he shook his head and went to the river with his fishing rod.

In fact, Wang Li did not give up!

Lying on the Taishi chair, still thinking about the reason for the failure!

NaCO3 + Ca（OH）2==NaOH + CaCO3

The equation should be right!

Why do you keep failing?

What's this reaction called?

It seems to be a "displacement reaction", right?

I'm a chemistry scumbag, but I think I'm not mistaken!

Wrong! If you remember correctly, then there must be a mistake!

Belch...... Displacement reaction!

Kim, it seems to be Au, right?

Aluminum, it seems to be Al, right?

Copper, it seems to be Cu, right?

Could it be that Al+Cu==Au+Cl is the real displacement reaction?

Well, that's right!

That's how it should be!

Copper, there is!

Who's that, find me some pieces of aluminum!

Depend on!

In this era, it seems that there is no aluminum yet!

Depressed!

If you want to exchange some gold, you have to open an aluminum mine first!

The copper coins of this era have a very high copper content!

However, it is not easy to get a slightly higher purity aluminum!

The book says that it seems to be electrolyzed!

Depend on!

In this day and age, there are no batteries, no generators!

However, as long as you can replace Al and Cu with gold, it is worth spending some time making batteries and generators!

However, to make batteries, you have to use chemistry!

I'm a chemistry scumbag!

Why don't you try making a generator?

Generators, it's easy!

Two magnets, a few copper coins, and you're done!

Poor study of history, poor study of geography, poor study of chemistry, I admit it!

When I was in middle school, I often scored 100 points in physics!

"Song Zhe! Immediately send someone to Shanxi, find the iron casting craftsman over there, and draw me a few hundred meters of copper wire! ”

Song Zhe was confused, but Wang Li stood up: "It's raining, don't go for the time being, I'll draw a few pictures first!" ”

In this era of cast iron technology, it is very easy to make a few round iron rods!

It's also easy to make some "silicon steel sheets" of the same size with cast iron and make holes in the middle!

The toy motor in my memory is used as a generator in turn!

Absolutely, yes!

I can make it!

I tinkered all night and redrew countless times!

Finally, several generators of different sizes, along with the accessories needed for each, were all drawn!

Jinyi Wei quickly left, Wang Li twisted his neck, but there was no trace of Liu Ruyan.

yes, I didn't see her all night!

Oh, maybe I'm going to get into trouble again!

This girl looks gentle and virtuous!

As soon as I arrived in Sichuan, my temperament became wild!

Last month, I went to pick mulberry leaves, and my hands were red and swollen from being stung by "foreign spicy seeds", and it took more than ten days to recover!

Just a little bit, I took someone to cut the sweet potato vine, and I actually caught a green snake and came back!

Nima!

A green snake more than one meter long, so scary!

I don't even dare to catch it!

If you see it, you will hide away!

This girl actually carried its tail and came to a "group of demons dancing"!

I also cooked it myself and made a pot of broth!

The point is, I finished eating it all before she told me it was snake soup!

It's all over the place!

I can't eat for two days!

This girl actually said, "Snake Meat Stewed Chicken" is also called "Dragon and Phoenix Fight", which is a famous dish!

It is also said that it is difficult for ordinary officials or wealthy squires to take a bite!

I'll go!

It's okay not to eat such a famous dish!

In the past few days, as long as I see her, I think of the half-dead green snake!

I'm afraid, she pulled another one out of her sleeve!

"Factory father! Factory Father! Aunt Liu's hand was hurt by something!

What a big piece of skin has been dropped!

It is said that it hurts hotly ......"

I'll go!

Sure enough, I guessed it right!

This Nizi is not restless at all!

What about people?

Where's she?

How did it get hurt?

"Factory ...... Concubine...... Little maid...... I just grabbed some baking soda flakes and stuck to my hands...... Woowoo...... It hurts......"

I'll go!

Crying pear blossoms with rain!

Looking at this posture, it hurts more than being stung by a "foreign spicy"!

Belch......

It's just a small skin wound on the tip of the hand, and it doesn't lose "a big skin"!

It's not broken, it's not in the way!

Soda flakes?

Soda flakes or baking soda, not so corrosive, right?

Hey?

In the bottom of the tank, milky white, covered with a layer of liquid......

I go N

Could it be caustic soda?

"Your finger was injured by this thing?"

"Hmmm! When I first started, there wasn't that much water!

The little maid thinks...... It's not quite the same as what the factory does, so I want to pick it up and take a look...... Then, it quickly stuck to your hands...... Woowoo woo ......"

I'll it!

This...... It's really caustic soda!

"Quickly clean it, smear it with some lard, and bandage it again!"

"Poof......

I'll go!

It's really the same as on TV!

When you tear your clothes casually, they become bandages!

However, I have tried so many times and failed to make caustic soda, how do you make it?

"Uh...... Didn't do it?

After you went out, the concubine only added some firewood to the bottom of the tank!

Then, then, didn't it rain, the concubine added a lid and continued to boil......

And then, that's it......"

Rain?

Lid?

Lid?

Scold!

I probably get it!

In fact, the first time I tried it, it was already a success!

The reason for the failure is that the evaporation rate is too slow!

It takes two days to evaporate a large vat of water every time!

There is not much sodium hydroxide in shortage!

Absorbing carbon dioxide from the air, doesn't it become soda?

She added a lid yesterday and hasn't taken it off!

Absorb much, much less carbon dioxide!

The small fire at the bottom of the tank kept burning!

At dawn, it just evaporated!

Scold!

This girl, by mistake, actually got it!

Who's that, hurry up and get the contents of the tank out!

And lard, hurry!

……

A few fingers were wrapped around the "bandage", and Liu Ruyan was still restless!

Take the milky soap and look left and right.

Then I got to my nose and sniffed.

Also stick out your tongue and lick it carefully!

"Gonggong, the soap you make is much better than the "fragrant alkali" brought by Jingshi! I can't believe that soap is actually made of lard! ”

"Ahh......h

Wang Li was still thinking about replacing Au, and Liu Ruyan spoke again: "Factory father, if you add some rose dew or peach blossom dew, will it bring a little fragrance?"

If you add a little alizarin or bloom, will it change to other colors? ”

"Yes! Definitely! ”

"That'...... Can it be made into a heart shape? Oval or bun-shaped? ”

"Yes! No problem at all! ”

"Factory father, the concubine knows how to make soap! Or...... Do you allocate some manpower and concubines to help you do it? ”

"You...... Do you really want to do it? You really can't be idle! ”

"Oh, Sister Qian is making money, and the concubine can't be idle! Factory father, you allocate a few thousand taels of silver......"

"I'll give you 100,000 taels!

However, the place of King Ning's Mansion is too small, so you have to build a workshop with a big top and a big top!

The clay jar we used for the test is also too small, and we need to fire several larger clay jars! ”

"It's okay! As long as there is silver, as long as there are craftsmen, the concubine body will be able to make it! ”

Liu Ruyan's posture is not like a joke!

That's it!

If she wants to do it, let her do it!

I'm just having a good time!

If she has something in her hands, she won't have time to catch snakes everywhere, and she won't make the house full of silkworms!

Those long worms or short worms, just look at them and get goosebumps!

Today's wind and sunshine are beautiful, and it is a good time for fishing!

I came out with a fishing rod and a wooden barrel, but I was shocked by the image at the door!

This one......

A large group of old and weak women and children knelt at the door, what kind of commotion?

"Factory Gong, Governor Zhang received the imperial court's holy decree to send troops, and the chief soldiers Deng Xi, Yang Yuchun, and General Ma Fengyi are recruiting troops......"

"Damn! I'm not asking about recruitment!

What I want to know is, why are these people kneeling at the door? ”

"Factory, I'm not talking about it...... This one...... It's because of the conscription order!

The people were unwilling to share the military salary, so the county government forcibly arrested people and forced them to share them! ”

Song Zhe explained, Wang Li was a little angry!

The county governments in various places only ask the people to share some military salaries, and they are not without strong men!

Doesn't it say that "the rise and fall of the world is the responsibility of the husband"?

Isn't it right to ask you to pay for it?

However, I'm here in Jinyi Guard, not the county government!

If you have an opinion, you should go to the official master!

It's not my business!

"Factory father, this is the reason, but ...... Didn't you promise to "never give"!

Nowadays, the county governments in various places want to levy "salaries", and the people are naturally unhappy!

Besides, this "salary" is not low!

Every citizen must pay 200 yuan! ”

I'll go!

Seems to understand!

Those guys are not leviing "salaries" from the people, but looking for trouble in the West Factory!

In fact, the corruption of officials at all levels is just like that!

As the commander of the West Factory, Wang Li doesn't want to delve into it!

Open your eyes and close your eyes, and it's over!

After all, everyone is a fellow practitioner, hello, hello, hello everyone!

However......

It is the West Factory that promises to the people to "never be endowed"!

At this time, it is the county government of each state and government that is forced to pay taxes!

The people can't tell the difference between the "West Factory" and the "County Ya"!

They only know about tax increases!

It's only been a few months, and the "West Factory" has reversed!

The wheat harvest is about to be made, and a lot of forced labor is needed!

If there is no credibility, will the people still sign up?

In fact, with a little explanation, or a little more money, you can still get enough conscription!

I don't care about this little money!

It is intolerable that the silver goes into someone else's pocket!

Dirty water, but splashed on the body of the West Factory!
