The separated molasses can be boiled to make other sugars.

The whole process can be said to be extremely complicated.

Because Su Wu didn't use the full name of the ability, but used the ability in the place where the ability could be used in the future, so she didn't master the heat well at first, and wasted several pots of sugarcane juice, and the heat was too big, and the sugar was burned at the beginning.

It took nine trials before the two succeeded.

The sugar made by such a complicated procedure was really extremely white, two degrees whiter than the white sugar that Su Wu bought from those merchants in the Tang family.

The Tang family's white sugar is quite white when viewed alone.

But compared with the white sugar made by Su Wu and Feng Jing by carbonization, you can see the difference.

In fact, this can be understood, even if Ye Siyin is an encyclopedia expert and a chemist, but in ancient times, where there was no industrial base, it must have been difficult for her to use carbonization to make white sugar.

Su Wu has a special ability to help, so she can use the carbonization method well.

After that, Su Wan and Feng Jing also made the remaining sugarcane juice again, and processed the remaining molasses again.

After several times, the difference in quality of the sugar produced can be distinguished by the naked eye, and after more detailed sugar screening, the white sugar with large particles and small particles is divided into two piles.

"It's white sugar!"

Cotton white sugar is like snow, or flour as soft and soft, much smaller than white sugar particles, white sugar is more like crystals, particles such as sand, can reflect light, the grains are distinct, scoop up and fall, will make a rustling sound.

White sugar is more susceptible to moisture than white sugar, is not easy to store, and contains less sucrose than white sugar.

However, because the program obtained by the white sugar will be a few more steps of white sugar, and because of the small particles, the same spoonful of sugar is eaten in the mouth, because the contact area is wider, so that the taste buds can be more fully contacted, so it tastes sweeter than white sugar in the senses, so the price of white sugar will be higher than that of white sugar.

White sugar is already something that most people can't eat, and the squeamish white sugar is even more tribute-level.

It was precisely because he knew the preciousness of white sugar that Feng Jing asked, "How much do you plan to sell this for a catty?" ”

Su Wu doesn't have much research on product pricing at all, this white sugar, cotton white sugar still have to be graded and priced or something, it's a headache to think about, can you do one less arithmetic problem and do one less one?

"The Taoist said that this thing is equivalent to a by-product, it is not easy to keep, I know that cotton sugar is very expensive, but our mountain is high and the emperor is far away, even if I want to give it to the emperor to eat, who can guarantee that this thing on the road will not melt away, and it is not appropriate to sell it farther away, so this thing will be mainly used as a benefit for employees in our factory in the future."

"Not for sale?" Feng Jing was impressed by Su Wu, treating money like dung so much, has he not seen the simplicity caused by the world built by power and money, or is he really so money-worthy?

If Su Wu knew what Feng Jing thought, she would have to laugh like crazy, she just didn't want to settle more accounts.

One more product, it is not an arithmetic problem, but a series of arithmetic problems, her brain hurts, and she prefers to fight rather than do the math.

Feng Jing looked like a fool on her face, which made Su Jing reflect on whether Feng Jing could see that she wanted to be lazy?

She said with a slightly contemplative look, "Well, it seems that it is not good to eat too much sugar, children are prone to tooth decay, and it will not be good for the adults in the village to settle accounts with me in the future, so let's sell it, after all, there will be more production procedures for cotton white sugar, and the wages of workers who make cotton white sugar still have to be a little higher than that of workers who make white sugar, so sell it for 120 wen a catty." ”

Feng Jing wanted to see how Su Wan would react when she knew that she had lost a lot, stared at her eyes, and raised the corners of her mouth slightly, "Do you know how much the Tang family's white sugar sells?" ”

Su Wan shook her head, "Although the Taoist chief said that cotton white sugar, I haven't seen cotton white sugar sold anywhere I've been, so I haven't asked, I don't know." ”

Feng Jing scooped a spoonful of white sugar, turned his hand and poured it back into the jar, and the white fine sand rose as if it was snowing, "Cotton white sugar can't be bought on the market, because of the low yield, so it is basically sold to the palace, and the people in the palace like cotton sugar, not as toothy as white sugar." ”

…… Is white sugar toothy?

Such a statement really made Su Wu, who was used to it, speechless, and couldn't help but think of Princess Pea, sure enough, the royal family is Jin Gui, tsk.

"The price of buying white sugar from the eunuchs in the palace is 10 taels of silver a catty." Speaking of the back, Feng Jing's face was already cold, and his tone became a little calmer.

He wanted to see Su Wan's reaction, but he didn't expect Su Wu to have no reaction at all.

There was no expression of regret and chagrin at the price he had set too low, nor did he curse the royal family for being poor and extravagant.

"You listened to what I said, and you didn't have anything to say?"

Su Wu looked at Feng Jing, "Huh? What do you want me to say? ”

Forget it, Su Wan's brain is not good, and it is not the first time that he has known it, if there is any problem, it is better to ask directly, she doesn't understand, "Most people will envy or curse the royal family for being so extravagant." ”

Su Wu's book knowledge is not solid, but she has watched a lot of TV series, she remembers that the eggs Qianlong ate The Internal Affairs Office gave him a quotation of 30 taels of silver, and the eggs that the Internal Affairs Office gave to Emperor Guangxu were 34 taels of silver.

Of course, some people know that they have been wronged, and some of them will not be good if they eat kickbacks, after all, expensive things are worthy of the nobles in the palace.

So when she heard Feng Jing say that this white sugar was 10 taels of silver a catty, she didn't think it was strange.

If you want to say surprise, you can only be surprised that the eunuchs in this palace are not too greedy.

Su Wu didn't dare to say what she thought, the palace was too far away for Su Wan's life, and the people were not allowed to talk about things in the palace, so it was impossible for her to know what complicated relationships in the palace were.

So she diverted the topic and said, "What is not expensive for the nobles in the palace." ”

Feng Jing was very dissatisfied with this answer, and stepped forward, "That's it?" ”

Short people can always be overwhelmed by the height advantage of tall people, you are amazing!

Su Wan scratched her face and took a step back, "Then the other princes or something, how much silver is it to go to Tang's house to buy cotton sugar?" ”

"Three taels." Feng Jing raised his eyebrows, with a hint of sarcasm in his words, and his inquisitive eyes still did not let go of Su Wan.

I don't know why, he just wants to know Su Wan's answer.

"How do you know so clearly the prices of those nobles' purchases?"

“……”

Su Wu, who has always been sluggish, really felt a slightly dangerous coercion just now, but it was either the danger of the sword without eyes, or the survival instinct that she had exercised in the last days, which made her feel that this question could not be answered.
