Chapter 355: Playing New Tricks
"What's the matter, Aying!" Wang Sanlang looked at Su Ying lovingly.
When Ah He arrived in Chang'an, he was adopted by his cousin Wang Liulang, who had already passed away. Apart from living and eating at Old Man Wang's house, nothing else changed.
His wife is still in charge of his clothes for all four seasons. Old Lady Wang is in her sixties and has poor eyesight, so it is impossible to expect her to do needlework.
One should take care of his own child. Seeing that his son's clothes were torn and no one sewed them, his wife specially sewed new clothes and sent them to Old Man Wang's house.
When Old Man Wang learned that his children had to stay in Chang'an, he was really reluctant to let them go, so he sent a few letters with them and asked Ah He to take them and knock on the door.
This is the last bit of connections that Old Man Wang has.
The abandoned son of a fallen family has lost contact for many years. Whether he will remember the past or not depends entirely on the other party's thoughts.
Whether you give this favor or not, you only have one chance.
These were also planned by Su Ying for everyone, and Wang Sanlang was grateful.
"Uncle Wang, please help me make a batch of charcoal!" Su Ying said.
"Charcoal? What kind of charcoal?" Wang Sanlang was surprised.
It is a bit cold here in winter, but not cold enough to make a fire. If you want to cook, there are plenty of dead branches and fallen leaves.
"Knock the burned charcoal into pieces and then calcine it at high temperature!" Su Ying said slowly.
"?" Wang Sanlang looked at Su Ying, "What are you doing again?"
What does it mean to break up burned charcoal and then calcine it? Can it become something new?
"Make something good!" Su Ying smiled. "When will Uncle Wang be able to finish it?"
"Is it urgent?" Wang Sanlang asked.
"It's urgent. I have to use it before my brother leaves!" Su Ying said.
"Then I'll go back and burn it tomorrow." Wang Sanlang did what he said, and didn't even bother to harvest the rice at home.
"Thank you, Uncle Wang! This is your lost wages!" Su Ying handed over a piece of brocade.
"What is Ah Ying doing? It's just a small favor, why is it so serious?" Wang Sanlang was shocked.
This piece of brocade is worth at least thirty strings of cash. It's too exaggerated. It's just a delay of two or three days!
"Uncle Wang, keep it. You still need to recruit people, so I won't interfere. You can arrange it all!" Su Ying insisted.
"Well, okay!" Wang Sanlang didn't insist anymore. He had to mobilize at least four or five people. He couldn't just order others around for nothing.
We rode to Jinfeng Village and saw that the Li people were busy. We went to find the leader Ade.
"Grandpa, I want some brown sugar!" Su Ying asked for it.
"How much?" Ade asked without hesitation.
"Well, give me the whole pot of rice. Are you willing to do that?" Su Ying said with a smile.
"Why would you be reluctant?" Ade laughed. It was just a matter of a few pieces of sugarcane.
He called a few men to the sugarcane field, cut a few bundles of sugarcane, cleaned the stone mill and the big iron pot that had not been used for a long time, and started to squeeze sugar.
"Are you going to send him to Chang'an?" Ade and Aying were drinking tea in front of the stove in the hall.
"Well! The governor wants to meet the emperor, so we need to get some new things." Su Ying said with a smile.
"New things? Could it be that sugar can be used in new ways?" Ade understood.
"Give it a try. It's not certain whether it will work or not. The brown sugar will be enough for you to eat for a lifetime. But after five years, if you withdraw from other counties, I will pass on this technology to you.
I have what others don't, I'm better than others, I'm unique. When the streets are full of brown sugar, you can give it up and do something better!" Su Ying didn't hide anything.
"Ah, Ah Ying!" Ah De stood up, "Is there really any candy in the world better than this brown sugar?"
Su Ying smiled but said nothing.
"Thank you, Aying!" Ade bowed and said, how could Jinfengzhai be so fortunate to have met the noble Aying!
"What are you thanking me for? We are a family, it's just a small matter!" Su Ying said indifferently.
It's just bringing forward technology from hundreds of years later, not inventing it ourselves.
The brown sugar was cooked the next afternoon and put into a basket. Ade asked a Li man to drive an ox cart to deliver it to Su Ying.
"So many, what for?"
Mrs. Du looked at the two baskets full of brown sugar that were casually brought over, wondering what her daughter was going to do.
The eldest daughter didn't take the good things that others wanted but couldn't get seriously, so there was always an endless supply of brown sugar and honey at home.
"It's very useful!" Su Ying smiled and gave ten pieces to Yang Chunhua, "Second Aunt, this is yours."
"No, it's still early for me!" Yang Chunhua knew that her niece was going to do something big again.
"Take it! This is enough!" Su Ying stuffed it into her hands and handed it to her second aunt.
He took out another ten yuan and gave it to the old lady, "Grandma, this is yours!"
Knowing that she was going to show it off again, I let her use it to satisfy her little vanity. Now she has nothing to lack.
"Sister, what are you going to do now?" Xiaotao and Atang squatted in front of the basket and broke off the sugar residue to eat.
"Good stuff!" Su Ying scratched the noses of the two little greedy cats.
Two days later, Wang Sanlang also brought two baskets of charcoal chips. "Aying, what do you think?"
Su Ying grabbed a handful of crushed charcoal, which was dry and loose, very different from ordinary charcoal. This was activated carbon with extremely strong adsorption properties.
Charcoal and coal are crushed and then calcined at high temperature in an airtight chamber to change the internal structure of the charcoal and remove the oiliness in the charcoal. The inside of the charcoal is hollow and can absorb various impurities.
It is a commonly used process for modern filtration, purification, impurity removal and decolorization.
"Well, it should work! Let's try it tonight!" Su Ying nodded.
After dinner, Su Ying threw the brown sugar into the pot and added water to melt it again. Everyone looked at each other and shook their heads, indicating that they didn't understand.
Su Ying smiled without saying anything. When the water was almost boiled away, she added the yellow mud water.
"Hey, why did it change color?" I saw the reddish-brown color in the pot gradually fade and become lighter, and there was a layer of reddish-brown mud at the bottom of the pot.
Yang Dalang, Yang Erlang, and Wang Sanlang looked at the changes in surprise, not knowing why.
"Aying, why is this?" Yang Erlang asked.
"Yellow mud has an adsorption effect, which can absorb and precipitate debris and pigments in the water." Su Ying explained.
Scoop out the syrup from the pot and pour it into a colander covered with activated charcoal.
The leaky bucket is used to drain vermicelli. I'll borrow it and place it on the wooden basin.
The syrup, which still contains some impurities, passes through the activated carbon and flows from the bottom of the net into the wooden basin, becoming clear and transparent.
"This, this!" Everyone was stunned, it was so shocking.
"Is this the purpose of crushing and calcining charcoal?" Wang Sanlang's mouth was dry. Oh my God, he actually accomplished something big!
"Well, breaking it up allows for more complete calcination and removes the oily substances in the charcoal. The finer the charcoal, the better the filtering effect! It can absorb a large amount of pigments and impurities in the liquid."
Su Ying uncovers the mystery.
"Aying, is this candy still clumping together?" Yang Chunhua watched with great interest, as if it were a magic trick.
"Well, this sugar liquid solidifies much slower." Su Ying placed thin twine in different positions in the basin.
"What's going on?" Everyone became increasingly confused. Why put string in the candy? Could it still be eaten?
"Crystallization!" Su Ying did not explain, "You will understand in two days!"
"Sister, what is this candy called?" The greedy cat Xiaotao stretched out her finger, dipped it in the syrup and licked it. It was so sweet, much sweeter than brown sugar.
"Let's see the results in two days! There should be white sugar and rock sugar!" Su Ying was not sure which one it would be.
After some tinkering, two baskets of brown sugar turned into four basins of transparent syrup and one basin of brown-red yellow mud residue.
