With the strange eyes of Fang Sansan and others, Han Zhen carefully carried the pottery jar back to the backyard and placed it in the small warehouse.

I dare not put this thing casually, although it doesn't matter much, it's worth a thousand gold.

There was white sugar in the Northern Song Dynasty, but it was very rare.

Some of them are from countries such as Dashi, while some are made by sugar merchants.

When the sugar is boiled and cooled, an extremely thin layer of frost will condense. The craftsman needs to use special bamboo strips to carefully scrape them off.

Often, hundreds or thousands of kilograms of sugar can be boiled to collect one or two taels of sugar.

This kind of sugar will hardly appear on the market. Even if a wealthy businessman wants to spend a lot of money to buy it, there is no way.

It belongs to the real priceless market.

Since there is no on the market, Han Zhen has no way to refer to the price. However, considering that the rare thing is expensive, he thought that selling 20 jin of one liang at that time would be reasonable.

After removing the loss of these two jars of sand sugar, they can produce about 8 kilograms of white sugar, which is more than 2,560 jin.

The cost is only 15 coins and the profit is as high as hundreds of times.

What is huge profits?

This is the real huge profit.

Of course, when the sales volume increases, the price of sugar will inevitably fall.

Therefore, Han Zhen plans to strictly control output, which can also achieve the effect of hunger marketing.

This type of top luxury goods is not suitable as a pillar industry, so you can only do it with it.

The difference is that fine salt is not as high as sugar. Although the profit is not as high as that of white sugar, it is a long-term transaction and can drive a series of industries.

After leaving the small warehouse and locking the door, Han Zhen planned to start making fine salt.

When he returned to the Second Hospital, he saw Fang Sansan and others holding bowls and drinking in small sips, his eyes full of enjoyment.

Han Zhen said curiously: "What should I drink?"

"syrup."

Fang Sansan replied with a pout.

She was still grieving Han Zhen why she would rather pour the sand candy into the mud jar than give it to herself.

It turned out that when I was cooking the sand sugar just now, there was a little sticky in the pot. Chef Shen couldn't bear to waste it, so she added water and rinsed it.

The shabu shabu candy water has little sweetness, but it is like nectar and jade liquid for the other party.

Han Zhen ordered: "Go to the village to find some children, and I said I would collect shells, which cost five cents per pound of shells."

shell?

Fang Sansan thought Alang was weird today. He poured the sand candy into the mud jar and then collected the shells.

The shells are useless. I grab a lot of people by the river, but they are worth five cents per pound.

As if he was afraid that Han Zhen would be angry, Fang Sansan didn't dare to say anything, so he went out with sugar water.

There are many children in the village, and now the adults are going up the mountain to find fugitives, leaving them to play themselves.

At this time, the children in the village heard that they collected shells for five cents per kilogram, and they all looked like crazy, carrying baskets and running to the river.

Taking advantage of the time when the children in the village grabbed shells, Han Zhen carried a hoe out of the house.

Looking for a small earth slope, he waved his hoe and quickly dug out a pit of earth that was one meter square.

After digging a vent at the bottom of the soil pit, an extremely simple small earth kiln was done.

At this moment, Ma Sangou and others who were patrolling noticed him and couldn't help but walk up and asked, "What are Brother Han doing?"

"Fired kiln."

Han Zhen responded casually, and then ordered: "By the way, help me find more firewood."

"good."

Ma Sangou and others nodded, turned around to find Chaihuo.

Soon, the five people found a pile of firewood.

"Brother Han, we're going to patrol."

"Go."

Han Zhen waved his hand and buried his head in the bottom of the earth kiln with small stones.

After a while, a child came with a shell.

Fang Sansan was also here. After so long, she hadn't finished her bowl of shabu shabu candy water.

"Come here to get the money."

Fang Sansan held the bowl, now he was like the king of children.

There is no scale here, and she doesn't plan to weigh a lot. She just counts on the basket and gives her five cents a full basket.

Even so, Fang Sansan still felt that his Alang was losing money.

The children don’t care. Shells are useless at all. They are everywhere by the river, so I’m very happy to be able to exchange for a few cents.

After receiving the money, he laughed and watched the fun.

Quicklime is required to purify refined salt, but Han Zhen only understands the steps roughly and has not actually operated in his previous life, so today is in the experimental stage.

Therefore, he simply dug an earth kiln. After the experiment was over and it was confirmed that it could be successfully mass-produced, it would not be too late to build a earth kiln for firing limestone.

As for why you use shells, it is because it is fast and can be cooked in more than half an hour.

If it is replaced with limestone, it will probably take at least seven or eight days to burn it.

After neatly placing one layer of firewood and one layer of shells, Han Zhen took out the fire broker.

After ignition, the earth kiln ignited a raging flame.

"Let's go!"

Han Zhen patted the dust on his hands and asked Fang Sansan to go back.

After taking a sip of candy water, Fang Sansan finally asked her doubts: "What is Alang doing this?"

"make money!"

Han Zhen said mysteriously in his tone.

Can this make money?

Fang Sansan felt that his brain was a little insufficient.

When she was waiting to approach the house, she realized that it must be Alang who was tying herself.

...

...

Three o'clock in the afternoon.

Han Zhen and Fang Sansan came to the earthen kiln again with the clay pot.

After so long, the earth kiln has completely cooled down.

After peeling off the thick ash, Han Zhen selected the complete shells from them.

There were five or six baskets of shells, and in the end, less than one can was selected. The rest were burned into slag and mixed with wood ash, and it was useless at all.

When he returned to the house, Han Zhen filled the pot with water, while instructing Aunt Shen to pour the coarse salt into the pot and add water to boil.

As the water was added to the clay pot, it quickly reacted with quicklime and bursts of white smoke emerged.

Stir quickly with a wooden stick and a can of lime milk is finished.

Seeing this amazing scene, Fang Sansan suddenly thought of something and lowered his voice and said, "Ah Lang is refining alchemy?"

If it weren't for the Taoist method, how could bubbles and white smoke appear in the shells if it weren't for the method of Taoism?

I think the same is true for the sand sugar in the morning.

Well, that must be the case.

The more Fang Sansan thought about it, the more he felt it made sense.

Alchemy?

Han Zhen glanced at her in surprise and couldn't help but quip: "That's right."

At this time, the voice of Chen Chuan came from the kitchen: "Alang, the salt water is boiling."

"good!"

Han Zhen nodded and walked into the kitchen with three wooden barrels.

Since it was an experiment, he prepared three barrels of salt water and wanted to test the optimal ratio of lime milk to salt water.

Carrying three buckets of salt water back to the yard, Han Zhen picked up the clay pot and started adding lime milk to the salt water one by one.
