Traveling to Daliang Kingdom starts from falling into the water

It's a pity that Gu Yangwen was wary of Mr. Gu and Gu Erzhu interrupting him.

After studying hard for decades, he still didn't realize that Gu Erzhu had actually made a move to retreat in order to advance.

He still doesn't know his second brother well enough.

Gu Erzhu knew that his old son might not be able to leave even if he wanted to because his father was present and causing trouble, so he simply coaxed his father to the side of the tea room and slowly pulled him away.

For example, when our children get older, we can no longer treat them as children, right?

Otherwise, how would they grow up and know how to be a good father and a good grandfather later on?

On the other side, when Gu Wenxuan heard that Gu Dalang mentioned that Bai Juren came to the village to learn guidance, he did not beat around the bush and gave a short answer.

First of all, before the Qingming Festival, Baiju people should study in the village before noon every day. The afternoon may vary, and they will not be there at night. If they want to attend classes, it is best to go before noon.

Secondly, the content of the lectures is not complicated. Each of them is assigned a question on time every day, and the problems will be pointed out one by one after being reviewed and corrected.

Finally, and most importantly, I have to review more than a dozen people's articles every day and point out problems one by one. After all, I am old and have limited energy.

Regardless of whether they listened or remembered it, he basically said it once and that was it. If you ask again, I will ask Zhou Xiucai to answer.

Gu Dalang understood, and Bai Juren could give guidance, but if he had to patiently explain it again, it would never be possible. As expected of Juren.

"What about you? If he says it again, can you keep up?"

Gu Wenxuan immediately shook his head.

"What about you now?"

Gu Wenxuan smiled and elaborated on how he studied and studied during these days, and how he lit up a lamp and read at night.

After saying that, he slapped his forehead and excused himself. We would get together after the exam. He was currently busy studying and went back to the west wing.

Look, he still has to ask his Liulang to come out and meet him.

What can his Rokuro say? It's just nonsense.

However, some people believed Bai Juren and told him again that his Liulang couldn't keep up.

Gu Erzhu sent Mr. Gu and the others away dumbfounded, thinking that they really thought that Liu Lang of his family had become the county chief through some bad luck.

That's all the old man thought, but even the boss and the older men couldn't tell that the half-truths and half-false words in his Liulang's words were all polite remarks.

It seems that he said a lot of nice things, but none of them were true. The children who talked less were the ones who said the same thing ten times, and they were all very happy without getting any benefits.

Turning back to the inner courtyard, Gu Erzhu saw that his old son was not affected at all. In less than a quarter of an hour, he was already immersed in reading a book in the study room of the west wing.

well.

It seems that his Liulang has not been affected by his grandfather's partiality, nor has his mood been affected by Dalang's arrival. He is indeed his stable old son.

Like Ojiang and Li Geer, they were focused on their studies and did not let anyone in. They only raised the curtain at the door, and the three of them did not notice his arrival at all.

After he quietly left the west wing, Gu Erzhu saw that Zhou Banxia was still hiding in the corridor leading to the backyard, tinkering with the waste oil at the bottom of the pot that could not be used to make pancake.

The so-called waste oil at the bottom of the pot means that after cooking, there is still some turbid soap and bottom alkaline waste liquid left in the pot.

It was freezing cold before, and Zhou Banxia was too lazy to move.

Now, the weather is getting warmer. When the workshop over there is completed, all the oil here will naturally be moved to the workshop, and the accumulated waste oil will have to be disposed of. After "nearly two months of careful consideration" and "recent days of experiments," Zhou Banxia "finally" poured the prepared brine into the iron pot filled with waste oil at the bottom tonight.

After vigorously stirring and heating, not only the oil wax was "successfully" made, but also a little smelly water - glycerin was obtained.

Although it cannot be compared with what is produced in a modern small handicraft workshop with complete equipment, she still made it after twenty years.

Chemistry was not returned to the teacher. After lard is reacted with caustic soda, soap is obtained. After adding hydrochloric acid, in addition to the particularly precious glycerin, wax is obtained.

Wax is the candle used for lighting in the home.

In this way, lard is reacted with caustic soda to obtain soap, and some of the insufficiently reacted fat can undergo an acidic reaction to obtain a little glycerin, and can also be used to make wax, effectively avoiding waste.

At this time, the mother-in-law and daughter-in-law squatted in front of a pottery plate filled with oil wax, used the bowl as a mold, pressed a small section of cotton thread on it, and asked for a "light candle" on the spot.

Under the light of torches from high places and lanterns nearby, the light was still good. Gu Erzhu saw Liu lighting the cotton thread in the bowl without going anywhere near.

done?

If you want him to say that Yizi has made a lot of money, he doesn't need the waste oil at the bottom of the pot.

But his Sanya was unwilling to give in. She said that since butter can be used to make butter wax, she should think about it again and maybe she could figure it out.

It’s really done!

Looking at the flames that were obviously much brighter than the oil lamps, Gu Erzhu stepped forward quickly and quickly grabbed the work of lighting the cotton threads in the remaining bowls.

Mrs. Liu was very amused when she saw this, so she didn't try to compete with him. She looked at it for a while and said, "Dad, not only are each of them brighter, but the smoke doesn't seem to be too big."

Zhou Banxia had fun, thinking that of course it was not a big deal. After several processes, the remaining oil wax had much less impurities, so the smoke was less than that of ordinary wax.

"No, this wax has a bright flame and low smoke. It is a high-quality wax. If you sell it, you should be able to get a good price."

"I mean the price?"

Mrs. Liu said with a smile, "Why don't you praise your child for his good brain? You child, you said how did you grow your brain?"

Gu Erzhu laughed loudly and immediately stopped talking, "I don't want to praise my children. Our children are just a little smarter than ordinary children. Remember."

The words were paused, and even Zhou Banxia burst into laughter.

"You silly kid." After Gu Erzhu said this, he saw that the mother-in-law and daughter-in-law were so happy that they couldn't help but laugh too.

After observing for a while, he found that the quality of the wax produced was actually better than the paraffin wax and insect wax on the market, and was only second to the best butter wax.

Another good thing.

Don't just put it in a broken bowl now, it's soft and limp, just put a thick cotton thread on it, but you won't make money again when it's made into candles.

Ordinary people all use oil lamps, and candles are something only rich people can afford.

Among all kinds of candles, paraffin wax is the second most expensive. It has a small pyrotechnics and is slightly brighter than an oil lamp. The most expensive one is tallow wax made of butter and mutton fat.

Butter wax is also the most popular among wealthy families because of its low smoke and bright flame, so the price is naturally the highest. The smallest piece of high-quality butter wax costs at least 100 yuan.

But the lard wax in front of me is made of lard, let alone the waste oil at the bottom of the pot. The cost is not much lower than that of butter or mutton. The key is that lard is easy to buy.

This kid has found another way to make money. Thinking of this, Gu Erzhu had to remind him, "This recipe must also be guarded."
