No wonder there is a lingering strand, several intertwined, different smells of fishy smell.

After Fan Jinyan told the old man to get up, he beckoned him not to leave first, and asked his soldiers to lead him to the side hall to rest.

At this end, Fan Jinyan began to do experiments. A large family is not a noble birth, Liang Xiangru helped to light the fire, and Fan Meng took the initiative to sort the plate oil and cut it into small pieces. As for Han Yaxuan, uh, Mei said that her name was to help Fan Jinyan fan, I'm afraid it smelled fishy!

At this moment, Fan Jinyan suddenly realized that he should buy a few maids to come back, since the third daughter followed him, although his identity seemed to have risen a lot, but he still did the things himself, and he didn't even have a helper.

But Fan Jinyan also understands that it is not yet time to enjoy, and when he has mastered the entire Qiongzhou, he may be able to let them stay at home and enjoy happiness with peace of mind.

Shaking his head, Fan Jinyan stopped thinking about it and looked back at the pot.

The first thing to go to the pot is the lard board, and after the oil pan slowly heats up, the oil plate also slowly begins to expand and produce oil. With a cup of tea, the lard board in the pot slowly turned from swelling to oil residue, and most of the pot of hot lard was refined.

Fan Jinyan brought over the wooden barrel that had been approved in advance, and poured the lard in the pot into the barrel with Li Yang.

This process was repeated several times, and finally several different oils were refined.

The rest is the fine work, Fan Jinyan took matters into his own hands, or started with the lard first, poured the lard in the bucket back into the pot, and continued to boil while adding an appropriate amount of sea salt.

Gradually, as the temperature in the pan rises, the oil in the pan begins to tumble until a layer of white fatty acids rises on the surface. Fan Jinyan knew that it was successful, and this white paste-like thing was soap.

At this time, Fan Jinyan took the copper basin in the hands of the soldiers to wash his face, put the soap horn powder, flower petals, and mint in it, and scraped the soap on the surface of the pot and put it in the basin. This process is carried out until the oil pan no longer produces fatty acids, and what remains is what is often referred to as glycerin. But this kind of thing is generally used for industrial raw materials, and it doesn't seem to be useful now.

But Fan Jinyan was still reluctant to throw it away, to see if he could do something else.

Next, he boiled several other animal oils to produce fatty acids, like lard, and put them in a copper basin to cool.

"Lao Fan, are you sure this is soap? Why the process is so disgusting to watch. Li Yang looked at the steaming soap in the basin and said with a disgusted expression.

Fan Jinyan glanced at the expectant eyes of the women, and didn't want to scold him, but smiled faintly and said, "I'll know if I use it for a while." ”

After cooling, a wooden board was placed on the ground, and the copper basin was turned upside down, beaten, and the soap that had been formed into a whole piece was poured out.

In fact, the refining process of soap and soap is the same, but there are some differences in materials, and the soap of later generations is mostly refined with vegetable oil, but it is purified on the basis of soap, and some flavors are added, and soap is also soap. At least, what this white thing is called now is all in Fan Jinyan's thoughts.

Touching the smooth surface with a hint of residual warmth, Fan Jinyan smiled, knowing that he had succeeded, now it is to see which oil has a better effect. Of course, the best test subjects are three women who are already impatient.

Fan Jinyan cut a small piece on each of them and handed it to them, asking them to wash their hands on the spot to see which effect was better.

When water came, the three girls first picked up the soap with a hint of floral fragrance in order and began to wash their hands.

As soon as I washed it, Fan Meng, who likes to be startled, screamed, startling the two men, there will be no problems!

But when I heard what she said, I wanted to beat her ass to pieces, "It's so cool." ”

Don't talk nonsense, of course it's cool with mint.

After some experiments, the women's hands also became white and clean. After some communication, they came to the conclusion that it is very easy to use, especially the mutton fat one, which is better than others.

Fan Jinyan nodded, and asked the soldiers to go, and the old man who had been waiting for news in the side hall came to him. The reason why I want to break him away is nothing more than to keep it secret, after all, this thing is not so complicated, and a discerning person can understand it at a glance.

Although there was tea waiting in the side hall, the old man was still restless, not knowing what the old man Zhizhou wanted to do when he left him. When he was led back to the backyard, his oil board was gone, and all he saw was an upside-down piece of white plaster on a wooden board.

Fan Jinyan didn't talk nonsense, and asked the old man the price of these oil boards.

In the end, it was found that the price of lard was the cheapest and the supply was the most stable, and the butter was the most expensive and unstable. After all, it is illegal to kill cattle in this era, and even if there is beef for sale, it must be reported to the government.

As for mutton fat, Fan Jinyan didn't think about using it, the smell was too difficult to get rid of, although the effect was better than the others, but it still smelled.

After discussing business cooperation with the boss, Fan Jinyan sat down to take a breath, and now he is waiting for Li Tong

Within a few days, Li Tong came to the door in person, saying that he was ready, and came to ask where Fan Jinyan was going.

The specific place of the development zone, Fan Jinyan plans to build it on the south side of the city, and the wharf is also planned to be built in that location, which is convenient and convenient, close to himself, and good at management.

As for the shipyard, Fan Jinyan had already thought about it when he first saw the Nameless, and built it at the location where the Nameless docked, where the bay was densely wooded and close to the materials. Now we just have to wait for the boatmen sent by He Yi to arrive, and we can start building.

Fan Jinyan sent 3,000 of them to the mines to open the mountain, and the limestone was broken into small pieces, and piled up, waiting for the blacksmith to bring the iron stove. Two thousand men went into the mountains to cut down trees and used them to build docks and shipyards. The remaining 5,000 people, according to the drawings given by Fan Jinyan, laid the foundation for the development zone, transported sand and pebbles, and so on.

A few days later, all the shipwrights sent by He Yi also arrived, and Fan Jinyan was not polite, and directly sent them to build a dock and a shipyard, after all, they were professional.

At this time, the cement furnace that Fan Jinyan dreamed of was also ready, and it looked like a big oil tank, which could only be pulled by three cows.

Fan Jinyan has already prepared the stove for these ten big guys, and now he is waiting for it to be put on the shelves.

Because it was too high, there was no channel steel fixed at this time, and the stove seat made by Fan Jinyan was equivalent to the climbing building of the soldiers trained by the army in later generations, a full four stories high, and to put this thing in, a lever nearly 20 meters high was specially made. The installation of these ten furnaces alone took nearly twenty days, and thousands of people joined.

When everything is ready, it is time to test the fire, and after the workers who burn the fire light the stove, they keep adding carbon. The rest of the furnace workers also carried small pieces of limestone up a four-story staircase and poured the clay-mixed stones into the furnace. Once filled, the lid is closed, and as soon as it is fired, the cement slides from a specially reserved pipe into a cloth-covered pit on the ground.
