"Honestly stay on the sidelines, waiting to witness the miracle happen," Wu Yuanqing felt like Liu Qian was possessed. Pen & Fun & Pavilion www.biquge.info

The wooden barrel is filled with water, and the water is soaked in quicklime, and the quicklime will react when it encounters water, and the water will boil and look like it is boiling, this kind of scene was often seen by Wu Yuanqing when he was a child.

At that time, no one in the village built a house or anything, and they didn't say that they didn't buy ready-made hydrated lime and sell it, they all dug a pond by themselves, bought quicklime and made it themselves.

There is a very large earthen pond below, and then a small reaction pond is built with bricks in the open space next to the pond, which is also a discharge pond, and then a hole is made on the side of the earthen pond.

Put the quicklime into a small pond, and then start to connect the water pipe to flush the quicklime, and when the quicklime reacts with the water, it will turn into lime soup, and then the soup will flow down the earthen pond along the opening. When everything is done, put a straw curtain on the top of the earthen pond and wait for the water inside to evaporate and seep.

The excess water is gone, and the rest is hydrated lime, also called lime plaster, which can live in the mud and sand to build the wall, and you can also add some glass silk or wool to plaster the wall.

However, Wu Yuanqing is not making lime paste in this wooden barrel now, but lime water, and after the quicklime has completely reacted with the water and becomes mature lime, he will take out the remaining residue and throw it away, and then start to add alkaline noodles to it.

The hydrated lime and alkali noodles will react again, and this time the water in the reaction bucket will go down again, and like the first reaction, it will evaporate a lot.

After precipitation, the bottom of the sediment is useless, and what Wu Yuanqing needs is the transparent solution on the top.

After pouring the clear solution into another wooden barrel, Wu Yuanqing carried it to the courtyard, where a large cauldron had already been erected. Pour the solution in, then scoop the lard out of the jar on the side and pour it into the pot and mix with the solution. Take out the fire fold and start a fire, and start stirring with a spatula while heating.

The lard and the solution start the main step of the saponification reaction at high temperatures. After the saponification was almost done, Wu Yuanqing took the salt and poured it into a bowl with water to stir and melt, then poured it into the pot and continued to heat and stir.

This step is called salting out, that is, the soap is separated from the dilute glycerol water, after salting, the upper layer is soap is also called soap particles, and the lower layer is glycerin water with salt.

At this point, you can remove the soap and pour out the glycerin water below.

Then put the soap into the pot again, add water and boil the soap grains, so that it becomes a uniform soap glue from the precipitated state, and wash out the residual glycerin, pigments and impurities.

Of course, after this step, there will be impurities in the soap, and at the same time, in order to completely saponify the residual oil in the soap particles, it is necessary to further wash out the glycerin, salt, pigments and impurities in the soap particles through alkaline precipitation.

After this step is completed, the color of the soap in the pot has been much better, the upper layer is much purer, and it looks pale yellow through the light. The lower layer is much darker in color and has more impurities.

After taking out the half-solidified soappaste from the pot, Wu Yuanqing took out a knife and divided the soappaste from the middle where the color began to gradually change, and then separated them into several boxes and pressed the porcelain.

Wu Yuanqing, who has a good color, uses the jewelry boxes of his two wives, and the poor colors are the jewelry boxes of the maid Zijuan and Xiao Feng, so he is not afraid of getting confused.

Li Chengqian watched Wu Yuanqing for a long time, but the result was finally out, but this guy pretended it directly, and he didn't even look at it, Li Chengqian was anxious: "Hey, why are you pretending, it's too stingy, don't even show it." ”

After finishing, he didn't wait for Wu Yuanqing to speak, so he said jokingly: "Oh, I know, what kind of soap do you must have failed, haha, failure is failure, you don't have to hide it, I won't laugh at you." ”

Talking about no jokes in his mouth, but what kind of weird and distorted smile is Nima, when Lao Tzu is blind

Wu Yuanqing said angrily: "Get out, can you speak, brother, am I the one who will fail?" ”

"It's not a failure, then you let me see, you won't die, besides, you just said that you want me to witness the miracle happen." Li Chengqian raised his eyebrows and grabbed white.

"Let's see if you won't die, then will you die, can't you wait until it's solidified and formed?" Wu Yuanqing also raised his eyebrows and asked.

"Okay, that's what you said, I'll wait to see what you can make," Li Chengqian said.

"Wait for a fart, go and call Li Tai and them, as well as Xiangcheng and Ziyu, let them all come and see my brother's great invention." Wu Yuanqing sat on the steps with his ass, and the big man commanded Li Chengqian.

"Okay, I'm calling them to come and see your joke" Li Chengqian squeezed his eyes at Wu Yuanqing and ran away with a grin.

After a while, all the people came running, more than twenty.

Wu Yuanqing took a look, oh, Zhen Nimaduo, I haven't noticed it for a few days, has the number of students skyrocketed to such a point?

Take a closer look, well, it's a bit of a fuss, because there are two wives in it, Er Ya, Wu Yuanshuang, plus Xiangcheng and Wang Ziyu, which accounts for five, and then counting Li Chengqian and Changle, Li Tai, Du He and Fang Yiai, this is ten, and the remaining dozen or so new ones are not much.

Wu Yuanqing entered the room with a few boxes and put them on the table, and the others stood around the three outer floors of the table, blinking and waiting to see the joke in Li Chengqian's mouth.

Wu Yuanqing opened Wang Ziyu's jewelry box, touched it and felt that the soap inside had almost solidified, so he put on a full posture, picked up the box and turned it over and said loudly: "The next thing is the moment to witness the miracle." ”

After speaking, he pressed the jewelry box on the table, then looked up at everyone and said, "Look carefully, you must look carefully." Don't blink. As he spoke, he proudly picked up the box.

Eyes looked around, waiting to see everyone's shocked and excited expressions.

However, because Mao is so quiet, and for Mao, everyone looks at themselves so strangely, especially Li Chengqian, Nima, are you looking at neurosis with these eyes?

"It's so embarrassing, don't you think this soap I made is very beautiful, beautiful like a work of art" Wu Yuanqing asked inquiringly.

No one spoke, just shook their heads.

"Have you ever seen such a beautiful soap, and you just shook your head?" Wu Yuanqing shouted in shame.

"Brother Yuanqing, where is the soap you said," little Lori Changle spoke.

Shenma

Wu Yuanqing hurriedly looked down, I went, the table was empty, what about the soap, what about Lao Tzu's soap, Wu Yuanqing looked down all over the ground.

"Hahahaha" An irrepressible burst of laughter sounded, and I saw Li Chengqian's tears of laughter coming out, and he laughed intermittently: "Second goods, it's in the sticky Nima box, hahahaha."

it, it's a shame.

Wu Yuanqing thought about putting it in the box and setting it, but he forgot that the jewelry box was not smooth, there were carved patterns on the two layers inside, and there was a bulge facing the inside, and then with the stickiness of the soap after solidification, it couldn't fall out of the box.

That's not all, Changle leaned over and looked at the soap in the box, sniffed it again, and asked puzzledly: "Brother Yuanqing, didn't you say it's called soap, why isn't it fragrant at all?" ”

Sister, the little girl doesn't open the pot, the brother forgot to add spices, and forgot to put the box into the box and pour it out directly after pressing and shaping, and then cool and solidify.

Sister's.
