This is not the Datang I am familiar with

"I'll let Meng Fei dispatch the manpower for you tomorrow. As for how to make soap, that's my business. You just need to manage this place!"

Yinye stuck out her tongue, and Chen Fang scratched the bridge of her nose.

"The son-in-law is really powerful. Soap has been around for a long time, but no one in the past has imitated it."

"Who did you learn to flirt with?"

"Learned from the son-in-law!"

Chen Fang was depressed, so he gave Yin Ye a hug, and the two were intimate for a while, and Chen Fang was about to get busy.

Soap making is not difficult to make. In fact, soap has been around for a long time, much earlier than people thought in later generations.

Whether in the East or the West, the original products of soap appeared around AD.

Chapter 322 Making Soap

In the West, this appeared earlier, as early as the Lianghe Ming period, that is, the Mesopotamian Ming.

In 3000 BC, people in Mesopotamia made the first washing items with one part oil and five parts alkaline plant ash.

In the ancient Roman era, people at that time used the dripping beef and mutton fat into the plant ash to form grease balls, and it was easier to wash clothes with it.

In Pompeii on the Apennine Peninsula, there was already a soap-making workshop in the second century BC, that is, soap-making had already been produced on a large scale at this time, and the principle was still the convergence of oil and alkaline substances.

In the East, the fruit of a plant was first used to clean clothes, called saponins. Even in later generations, there is still an industrial product called soap powder, and some manufacturers even call it natural soap for better sale. Powder, it can be seen that saponins are really easy to wash clothes.

In the Yangtze River Basin, since there were no honey locust trees, people found another tree with a similar effect to soap locust, called soap seeds, which is probably the source of the original name of soap.

In the East, soap was first artificially synthesized, using pig pancreas and lard, and the general principle is the same as in the West.Later, some places called soap and toilet soap soap, because of this.

In fact, the principle of soap is that oil and alkali are mixed in proportion.This can also be seen from the fact that soap in later generations just entered China, and it was called Yangjian.

Chen Fang remembered that when he traveled with Master, in fact, soap was called Yangjian in many places.

It is actually difficult to imitate Xiqin's soap making soap. The actual difficulty lies in the production of caustic soda.That is to say, the process of extracting trona from plant ash is replaced by caustic soda.Let soap making get rid of the primitive stage of using plant ash.

This is also the most fundamental difference between industrial soap making and traditional soap making.

For Chen Fang, making caustic soda is not difficult at all.

Caustic soda is a common name, the chemical name is sodium hydroxide, which belongs to strong alkali.

To make caustic soda, two things are needed, sodium bicarbonate, commonly known as baking soda, and calcium oxide, commonly known as quicklime.Of course, sodium bicarbonate can also be replaced with sodium carbonate, which is commonly known as soda ash.

Baking soda and quicklime are actually not difficult to obtain in this era. They are both naturally produced and supported by the royal family.

As for chemical production, Chen Fang can also make it. After all, he is a cosmetics maker, and chemistry is a compulsory foundation.

However, chemical manufacturing is a little more troublesome. Originally, Chen Fang did not plan to manufacture soap in large quantities, and using natural ones can also support the production.

As long as quicklime is dissolved in water to form a lime slurry, then add solid baking soda, and through a chemical reaction, sodium hydroxide, which is caustic soda, can be obtained.

The latter is much simpler, no need to go into details, it is just some proportion adjustment.

On the same day, a list was sent to the palace, Taohong was presented to Wu Meiniang, it mainly contained the raw materials for making soap and various spices that needed to be added.

Knowing that it was used to make soap in the Tang Workshop, Wu Meiniang naturally did not hesitate, and asked Six Departments to deal with it urgently that day.

On the second day, the raw materials had already been transported into the Tang workshop, and the royal family was acting vigorously and resolutely. With the order of the empress, the officials of the six ministries had to find them even if they ran away.If you can't find it, it is very likely that Wu Meiniang will really break your leg.

At this time, at the soap making workshop, the dozen or so healthy women selected by Meng Fei were ready, and Chen Fang demonstrated the making of caustic soda in front of them.

This is a small-dose demonstration, and since caustic soda is a strong alkali, Chen Fang reminded him several times not to touch the skin, let alone splash into the eyes.

Chen Fang watched more than a dozen healthy women make alkali, and corrected them carefully. He saw that one healthy woman didn't do what he said, and kicked the other's ass directly.

Chen Fang was seldom angry, but surprised the healthy woman.

"go out!"

Chen Fang pointed to the door, where caustic soda is made, and the most taboo is that caustic soda hurts oneself.

Based on the principle of safety first, Chen Fang will never allow anyone to mess around here.

As night fell, a few more butter candles were lit in the Ganlu Hall, and a dozen court ladies were waiting here, and clear water had already been placed in front of them.

At this time, if you look carefully at these maids, they all have dirty hands and faces. Looking at the dirty look, they did it on purpose.

The palace maid waited here, the main seat of the main hall, Wu Meiniang pulled Li Zhi, and was looking at the main entrance of the main hall.

"Your Majesty, Your Majesty, the son-in-law has entered the Xuande Gate with His Royal Highness the Princess!"

"Your Majesty, Your Majesty, the son-in-law has already passed Lingyan Pavilion with His Royal Highness the Princess!"

"Your Majesty, Your Majesty, the son-in-law has already passed the Dragon Palace with His Royal Highness the Princess!"

...

From time to time, little eunuchs would run into the Ganlu Hall to report to Wu Meiniang and Li Zhi about the itinerary of the son-in-law and the eldest princess.

When Chen Fang brought Yiyang closer to the Ganlu Hall, he had already seen His Majesty walking out of the Ganlu Hall from a distance, and behind them, there were not many concubines, princes and princesses.

The four concubines and nine concubines were all waiting here.The crown prince and the princes and princesses also followed the team of concubines.

Chen Fang glanced at it, and only sighed that His Majesty and Empress attached great importance to soap making.

In fact, Chen Fang didn't know, but for His Majesty, this scene still didn't satisfy them.

Originally, His Majesty proposed to invite all the Dukes of Wu and a group of princes and nobles to participate tomorrow morning.

But he really didn't want to wait until tomorrow, and it was too late for Chen Fang to send someone to report to the palace today, and it was too late to invite all the warriors at this time.

So His Majesty only let people notify the concubines and princes and princesses to come.

The Ganlu Hall was brightly lit at this time, and all the concubines, princes and princesses stood on both sides of the Ersheng.

Chen Fang was about to meet with Yiyang, but was supported by Li Zhi and Wu Meiniang who had already walked down the steps quickly.

At this time, there is no way to bow down and salute.

"Enter the palace!"

In the Ganlu Hall, the two sages sat on the front seat, and the concubines, empresses, princes and princesses sat on both sides.

The seat closest to His Majesty's Empress is currently vacant, and everyone understands that it is reserved for the son-in-law and the princess.

"Report to Your Majesty, Your Majesty, Your Majesty, Your Majesty, thank you for your appreciation!"

At this time, Chen Fang personally carried a silver tray and walked towards the Second Saint. According to the usual practice, no matter who offered something, the eunuch would pick it up and present it to His Majesty.

Because there was an incident of assassination by borrowing and offering things in the previous dynasty.The most famous of these is the incident in which Jing Ke lent a map of the city of Yan to the King of Qin, and then saw him with a dagger and assassinated the King of Qin.

Therefore, in all subsequent dynasties, the eunuchs took items and presented them to His Majesty.

But today, Li Zhi doesn't pay attention to this.In fact, he trusted Chen Fang more than anyone else, and he was his son-in-law.

Chen Fang brought the silver tray to the Second Saint.Peeling off the covering light yellow silk cloth, at this time the twelve crystal soap bars have appeared in front of the Second Saint.

"Your Majesty, please take a look!"

"Bring Xiqin's soap over here!"

Chapter 323 Making Soap

The eunuch quickly took a piece and presented it to His Majesty, Li Zhi took it.

At this time, the two bars of soap were put together, and Li Zhi took a closer look, but couldn't tell the difference, except for the shape, there was no other difference.

In fact, not to mention Li Zhi, it would be strange for anyone to be able to see the difference. The manufacturing principle is exactly the same, and the things produced are naturally the same, and the physical and chemical reactions contained in them are the same. How could it be different?

After reading it, Li Zhi handed it to Wu Meiniang.After reading it, Wu Meiniang nodded to Chen Fang.

"Let all the concubines and princes and princesses also take a look, this is the soap made by my Datang Workshop!"

At this time Li Zhi said, when he said that this is the soap made by my Datang Workshop, Li Zhi's voice obviously raised a level.

Although it is a common sentence, everyone in the hall at this time, no matter the empress or prince, or the court ladies and eunuchs, can feel the elation and high-spiritedness in His Majesty's words.

It has been almost a thousand years since the Chinese country imitated Western Qin to make soap, but for such a long time, there is no dynasty, no one can make soap from Western Qin.

The helplessness and unwillingness that had been accumulated for nearly a thousand years was finally made by Tang Gongfang, and His Majesty has seen it, and it is no different from the soap produced in Xiqin.

At this time, how could Li Zhi not be elated, how could he not be high-spirited.

When Li Zhi said this, Wu Meiniang, who was closest to him, looked at Li Zhi, and she could see the joy from the heart on Li Zhi's face.

Chen Fang also looked at Li Zhi at this time. His Majesty's excitement at this time is beyond words. The emperor who is usually high above him does not hide his heart at this time.

Wu Meiniang smiled lightly, but Chen Fang happened to see that smile, and Chen Fang quickly lowered his head.

It's better not to look at the empress's smile, it's too much to resist.

At this time, a piece of soap was taken out from the tray, and the maid took it carefully, and presented it to the concubines, who all looked at it carefully.

"My son-in-law, this time you have made great contributions to my Great Tang!"

Concubine Jing said a few words, and all the concubines began to praise the group model. Ten concubines praised Chen Fang together, which made Chen Fang really unbearable.

Being praised by a group of beautiful women in turn, hey, it's really a bit floating!

Let's watch it, all the empresses, only the prince and several princes and princesses will watch it there.

Li Xian and the others are still young, and Taiping is also young, but they can't see anything, just like ordinary soap.

Over there, Li Hong had already walked towards Chen Fang, holding the soap made by Tang Gongfang in one hand, but directly hugging Chen Fang in the other.

Chen Fang really wanted to kick the prince's ass in front of all the concubines and His Majesty, but actually hugged me in front of all the dignitaries in the hall.

I'm a man, not a woman.Girls hug me, I enjoy it, but it's so uncomfortable for you to hug me.

But Chen Fang didn't dare to kick it!At this time, looking at the young and handsome prince, with red lips and white teeth, how many rich women can be attracted to spend money in future generations?How many glass prying eyes did you invite?

"My son-in-law, it's really my great Tang's honor to have such a talent like you!"

Over there, the crown prince hugged Chen Fang. He had already praised him, but he hugged him even tighter!

"His Royal Highness, thank you for your praise, but the praise is too much. Making soap is the business of Tang Workshop."

"The son-in-law is a real countryman!"

After the prince said this sentence, he finally let go of Chen Fang.At this time, the two looked at each other, Chen Fang looked at the prince looking at himself, and quickly averted his eyes.

At this time, all the concubines, princes and princesses had finished watching. Wu Meiniang looked at Li Zhi, and the expressions of the two of them changed a few times. This is an exchange of expressions. They have been husband and wife for many years, but they have already understood each other so well that they can understand each other's thoughts without words. .

Li Zhi nodded there, and Wu Meiniang also nodded and smiled at Li Zhi.

"Try the soap!"

At this time, a group of maids came over and gently put the 12 yuan Tang Gongfang soap on the silver tray. At this time, Chen Fang noticed that there was another piece of soap in front of each silver tray, all of which were fresh from the luxury box. Take out the Xiqin soap.

These silver trays were placed in front of a row of dirty maids. At this time, these maids squatted down and began to wash their hands with the clean water in the basin in front of them.

One of the hands was washed with Tang Gongfang soap, and the other was washed with Xiqin soap.

Several court ladies who had their faces smeared with dirt also washed the left and right sides of their faces with different soaps.

The dirt on the hands and faces of these court ladies was different, ordinary plaster, kitchen oil stains, raw lacquer, blood stains, and some things that Chen Fang couldn't see.

After the maids finished washing carefully, they all stood up and stretched out their hands. Li Zhi pulled Wu Meiniang to look over one by one. Li Zhi called Concubine Jing and Concubine De. , and the prince followed closely behind.

"Meiniang, how are you?"

"The effect of Xiqin's soap is the same!"

"What do you concubines think?"

"Return to Your Majesty, there is no difference between the soap made by Tang Workshop and Xiqin soap."

"Father, we will no longer have to spend a lot of money to buy soap from Xiqin after the Tang Dynasty!"

"it is good!"

Li Zhi had a good word, and Wu Meiniang saw Chen Fang.

"Today, the son-in-law has made such great achievements for my Great Tang, just say what you need!"

Chen Fang looked at Wu Meiniang, she really still likes this kind of thing, every time she likes to ask what reward she wants, but this time, Chen Fang felt a little headache when she asked.

What reward do you want?This is indeed a problem.

First of all, you can't refuse, Your Majesty wants to reward you, but if you refuse, isn't this disrespecting Your Majesty?

This reward is first of all necessary.
