Just when Lin Haoran almost lost hope in soap, he was ready to go to Guangzhou to take the exam at any time, but he never expected that he would fall into such a big pie.

An order of 10,000 taels is undoubtedly quite astonishing. No wonder Mr. Shen Liu made this trip himself.

It's just that these Francois, who made their fortune by plundering, do have such confidence.

The Ming Dynasty was not an important silver-producing country, but silver had become the main domestic currency, so silver was very scarce. But not for these plunderers. Later data shows that Spain plundered billions of taels from Latin America alone.

Silver and nearly 100 million taels of gold.

The next day, Lin Haoran sent Dabiao to use the newly bought carriage to purchase raw materials. Almost the whole village was focused on this big project. He even brought back several pigs and sheep from the county, and they were drying grain in the field every day.

Big dinner party.

The dyeing workshop was temporarily suspended and turned into a soap workshop.

Lin Haoran asked Da Biao to lead a few people to clean the salt water pool, fill it with clean water, and then asked them to guard the door and not let anyone approach.

As pieces of quicklime were thrown into the water, a "sizzling" sound was heard, and the water in the pool became turbid and boiling hot.

Huniu watched from the side, her mouth opened with a smile, and then she turned to look at Lin Haoran in confusion.

When quicklime meets water, a chemical reaction will occur to form calcium hydroxide, commonly known as slaked lime. This chemical reaction process will produce an exothermic phenomenon, which will be strange to anyone who sees this phenomenon for the first time.

Lin Haoran scratched his head, but didn't know how to explain this exothermic phenomenon. He finally said: "Some things will become wet when put in water, and some things will not. Hot iron will become cold when put in water, and quicklime will become wet when put in water."

"Hot" to explain.

Huniu thought for a moment, nodded seriously, and secretly wrote down the magical thing like quicklime.

Lin Haoran poured an appropriate amount of soda ash into the pool, which is what the locals call alkali noodles. This soda ash comes from two sources, one is natural alkali minerals, and the other is plant grass alkali, but it is not known which type of soda ash it belongs to.

Baozi Shop can provide a channel to purchase this kind of stuff. The price can’t be said to be cheap, but it’s not too expensive either.

After adding soda ash, the exothermic effect became more obvious, and a large amount of white water vapor appeared and filled the dyeing workshop.

The advantage of Huniu being short is that when she looked at the white water vapor in surprise, the other two people hid far away. Dabiao who was standing outside asked worriedly and loudly, and the old patriarch immediately scolded him,

Let him lead the people and continue to guard the door sadly.

Worried that the reaction was not enough, Lin Haoran asked Huniu to get some water, pour it into the salt water pool and stir it. Huniu looked amused, so she helped him stir together.

The main chemical component of slaked lime is calcium hydroxide. Following the chemical reaction of sodium soda ash, calcium carbonate and sodium hydroxide are generated. Calcium carbonate is a kind of sediment. These solid sediments will slowly sink to the bottom, and the supernatant liquid is hydrogen.

Sodium oxide solution, commonly known as caustic soda.

These solutions of caustic soda are exactly what Lin Haoran needs.

Carefully filter the caustic soda with a filter bucket, mainly using fine cloth to filter out the solid sediment calcium carbonate in the solution, and put the caustic soda into several wooden barrels.

Lin Haoran heated half a pot of caustic soda until the caustic soda boiled slowly, then poured the purchased soybean oil into the caustic soda and stirred it continuously with a wooden spoon.

Grease and caustic soda will undergo a saponification reaction, which is actually a slow chemical reaction. If you want to speed up the reaction, in addition to maintaining high temperature, you can also choose to add an appropriate amount of alcohol.

A layer of viscous liquid slowly appeared on the top of the iron pot. This viscous liquid was exactly the soap Lin Haoran wanted.

After about half a stick of incense, there was more and more viscous liquid, but soybean oil still remained. Lin Haoran naturally understood that this was a sign of insufficient reaction, so he added caustic soda and continued stirring until no more soybean oil remained in the viscous substance.

until.

These sticky substances are actually soap, but after cooling, only a gelatinous soap with low purity can be obtained, which needs to be stored in a container for use, which is inconvenient.

Lin Haoran asked Hu Niu to bring salt water and add it directly to the viscous body. This would not only separate some impurities, but also obtain solid soap.

The old patriarch looked at Lin Haoran's action of pouring the salt water, and his heart ached. Not to mention the quicklime, the alkali noodles and soybean oil cost a lot of money. Now that he regarded the salt as money, he secretly cried out that he had committed an evil act.

But thinking about the money brought by Mr. Shen Liu, I felt that it was only reasonable to squander it like this. But looking at the various operations, this soap was really a waste of money, and it was indeed not something that ordinary people could make.

In order to obtain higher purity soap, Lin Haoran also performed a heating alkali precipitation treatment. After the alkali precipitation was completed, a thick layer of yellow translucent solid floated on the solution.

Huniu has been helping by the side and secretly noted down these steps.

Lin Haoran carefully took a white porcelain bottle and poured the essential oil previously obtained from the petals into it. The fragrance suddenly overflowed, making people feel intoxicated.

He carefully scooped the soap into a special mold, pressed the yellow translucent solids into soap shapes, and only needed to dry them, and these were beautiful pieces of soap.

Since he was targeting the European market, in addition to using the Chinese word "Chang Lin", he also used the English word "Scented soap". In fact, it is undoubtedly best to use Portuguese style, but who told him not to learn several foreign languages ​​and not learn English?

What about the Portuguese girl’s experience?

In these subsequent processes, Lin Haoran handed over the work to others to complete, after all, other people's hands were more skillful.

In order to establish long-term cooperation and improve the quality of "Changlin Soap", Lin Haoran provided flower cloth and asked the women in the village to embroider soap bags of corresponding sizes, and each of them was given considerable compensation.

This move made the village lively in an instant, and many women knew how to sew.

The women who got married in Changlin Village also brought their children back to their parents' home. Not only was there delicious meat, but there was also considerable income, which greatly improved the status of those who came to Changlin Village.

Previously, everyone despised Changlin Village for being poor, and there was a popular saying in Qingye Town that "if you marry a girl instead of a Changlin guy, you will have to worry about carrying water and eating." But now there has been a 180-degree change, and many women are looking for help.

The men in the village talk matchmaking.

In fact, in addition to this kind of cloth bag, Lin Haoran also wanted to get some small wooden boxes to raise the quality of soap to the fragrance-like level. But time was too short, and he also had to take the exam.
