The disgraced official I took care of was actually Zhu Houcong's childhood friend.

After settling for several days, the sugar water became moldy and did not become clear.

In fact, it wasn't just Zhou Chu; many video bloggers also tried making white sugar using the traditional method, but none of them succeeded.

not a single one.

However, there are many records of the method of making sugar from yellow clay, not only in the "Exploitation of the Works of Nature".

Ultimately, Zhou Chu was completely baffled and had to change his approach.

The core idea of ​​the yellow mud water sugar-making method is to use yellow mud water to absorb impurities in brown sugar water.

However, after numerous experiments by Zhou Chu, the yellow mud water he used did not have the effect of absorbing impurities.

Therefore, Zhou Chu came to the conclusion that the yellow mud water recorded by the ancients was likely not the same thing as the yellow mud water they understood.

Later, Zhou Chu simply used activated carbon as a control group.

It must be said that activated carbon is far superior in terms of adsorption capacity, with no rivals whatsoever.

Brown sugar that has been adsorbed by activated charcoal water is filtered to obtain completely transparent sugar water.

You can't see any color at all.

Therefore, Zhou Chu planned to use this method to make white sugar.

The first step, naturally, is to make activated carbon.

That's why I bought the charcoal.

Zhou Chu poured all the charcoal from the sack into a large basin and began washing it.

After washing it several times, the charcoal was laid out on a cloth to dry.

It was around 2 p.m., and the sun was high in the sky. Several relatively small pieces of charcoal were quickly dried.

Zhou Chu crushed the charcoal pieces with a stone mortar and pestle, then ground them into charcoal powder.

The toner was then placed in a metal can and sealed.

This process was repeated until more than a dozen iron cans were filled with carbon powder.

After finishing all this, it was almost dark. Zhou Chu wasn't in a hurry to go home, but instead placed the iron cans in the stove that he had specially asked someone to build according to his instructions.

This stove is sealed, with a vent at the top and a place to put firewood below.

Only a sealed stove can guarantee even heating and achieve the required temperature.

Zhou Chu then used firewood to ignite the bottom of the stove and began to cook.

This method of making activated carbon is rather crude.

But there's nothing we can do about it.

There are ways to make better activated carbon, though.

However, it would be too much trouble and completely unnecessary.

If you're just making white sugar, this kind of activated charcoal is perfectly sufficient.

Soon, jars of activated charcoal were made.

Afraid of burning his hands, Zhou Chu used pliers to hold a jar and poured the activated charcoal inside into a large basin of water.

After stirring for a while, add brown sugar in a certain proportion and stir until the brown sugar is completely dissolved.

After dissolving more than a dozen bowls of brown sugar water, Zhou Chu covered all the black brown sugar water, closed the door, and went home.

Let it sit overnight to allow the activated carbon to slowly absorb the impurities.

It was very late when Zhou Chu got home.

Because of Zhou Chu's instructions, Mu Yunjin went to bed early.

"Master, you are back."

Under the light, Xianglan saw that Zhou Chu's face was somewhat dark and his clothes were quite dirty.

This happened while making charcoal, and even if you wash it, it won't get very clean.

"I'll go prepare bathwater for the young master."

After saying this, Xianglan blushed and went to prepare bathwater for Zhou Chu.

Xianglan still remembers the first time she prepared bathwater for the young master.

Although she understood that it was only natural for a servant to serve her master while he bathed.

But he was only twelve or thirteen years old.

I've never experienced anything like this before.

It wasn't until the bathwater was ready that Zhou Chu waved for them to leave, and then he bathed alone.

Xianglan breathed a sigh of relief, but also felt very disappointed.

After all, the young master is so handsome; if only I could bathe him...

Xianglan blushed every time she thought of that scene.

Soon, the wooden tub was filled with bathwater. Zhou Chu waved his hand, and Xianglan and the others immediately understood and left.
