Eat in Song Dynasty

Chapter 343 Saltpeter Ice Making
As the saying goes, there must be a brave man under a great reward, and Wen Shu at this moment is the brave man who is tempted by the great reward.

She thought that since it was a personal note, it would not be lost in the book store.Since the owner of the book was an official of the imperial court, he probably had a friend or two.

Since that note is worthy of the reward of [-] points given by the system, the content must be very exquisite, and it should not be discarded casually, maybe it was given to a friend.

Wen Shu looked at the invitation in the box.Since the Zhao family and the Jiguo government just happened to hold a book exhibition, how could she miss such a good opportunity!And the Zhao family, there is another thing she pays attention to.

After making up his mind, Wen Shu replied to Miss Lu's letter, and then spent tens of pennies outside the door to recruit an idler to send the letter to the Hou's mansion, then went back to the house and sat waiting for the water to freeze.

The book does not clearly state the time when water freezes into ice, but only says that the greater the amount of saltpeter, the higher the purity and the faster the speed.The ground cream was bought by her father from a pharmacy. It is very pure, and she puts it in a lot. It shouldn't take too long.

Because it was the first experiment, Wen Shu was extremely excited, and she would go to have a look at every other cup of tea, but she didn't see a thin layer of ice formed on the surface of the small wooden basin until after five cups of tea passed.

It's just a thin layer of ice. Wen Shu poked it with his hand, and the layer of ice broke.How long would it take to freeze half a basin of water?

Wen Shu frowned, and finally understood why most of the predecessors still used the old method to store ice after they knew that saltpeter could make ice.

Because compared with the time-consuming and labor-intensive production of saltpeter, the method of digging ice for storage in winter is simple and crude, but also large and practical.

That's right, making ice with saltpeter was not an invention of thousands of years later, but someone discovered this method as early as the end of Tang Dynasty.

She asked Xiaoxing suspiciously at the beginning, since people have discovered that saltpeter can make ice, why do most ice shops still store ice in winter?
Xiaoxing only said two words, saving time.

She didn't understand what it meant at the time, but now she understands everything.If you really use this freezing speed in a hurry, don't be in a hurry.

Of course, if she increases the amount, maybe the speed will increase rapidly.It's just that she doesn't know how much it needs to be added to make it freeze instantly.

All she knew was that the small cloth bag of saltpeter alone cost several hundred renminbi.Even if it is doubled in size, or twice the amount can be instantly frozen into ice, she still feels that it is not worth it.

Because the ice produced in this way cannot be sold at the price of raw materials.

Although after the saltpeter is dissolved in water, the saltpeter can be taken out and reused by cooling crystallization method or evaporation crystallization method.But extraction also takes time.

In short, in the season when free ice is everywhere in winter, saltpeter ice making has no advantage at all.

Its advantage is only that it can be used for emergencies when it is urgently needed and the amount is not large.

She is backed by the mountain and sea world, as long as the system is successfully upgraded to level four, if she wants ice, she can get it at will.There is really no need to waste time, effort and money to make ice with saltpeter.

Therefore, after only one experiment, Wen Shu lost interest in making ice with saltpeter.

However, since the experiment had been done, she still wanted to wait for a result, so she continued to wait patiently in the main room.But waiting is really boring. After thinking for a while, she simply took out a piece of lotus flower from the storage basket and studied it carefully.

This time she took Zilian.It is said to be a purple lotus, but the outer skin of the petals is still white, but the juice inside is purple, the kind that turns purple to black.

Wen Shu pinched it with his hands, and there was still liquid flowing inside.Take it close and you can smell a faint fragrance.Different from the fresh and soul-cleansing aroma of yellow lotus, the aroma of purple lotus has a bit of dazzling charm.

There seems to be Venus jumping around in front of my eyes, huh?Why are you dizzy?
Wen Shu shook his head vigorously.

However, these actions did not make her conscious, but instead became more and more confused.It seemed that a big hand was pulling her consciousness away from her brain.

In an instant, she lost consciousness uncontrollably and lay on the table.

It wasn't until an hour later that Father Wen came back from Sun Heping's house and called her to eat, and then he woke up leisurely.At that time, the purple lotus on the table had already turned into a black lotus.

Thinking of the abnormal situation just now, Wen Shu felt that it had something to do with Hei Lian.

Just smelling it made her faint, this Zilian is so domineering!
Originally, she wanted to squeeze out the juice inside to take a look, but now she didn't dare to have such an idea anymore.Even if you want to do it, you have to arm yourself first, otherwise she will fall down before something else squeezes out.

Throwing the blackened purple lotus back into the storage basket carefully, Wen Shu went to the well to wash her hands carefully several times before she dared to take a bowl to eat.

"Father, you go to Uncle Sun's house today, are you feeling better after seeing your aunt?"

"It's still the same." Father Wen sighed, "It's just that the mouth is not so crooked, and the words are clearer."

"Then what does Uncle Sun want you to do?"

"It's not about your aunt. Seeing that it's hot, it's not good to lie in the house all the time. I want me to help make a bamboo chair."

"Father can still work as a bamboo craftsman?" Wen Shu asked in surprise.

"Where is it? Naturally, the bamboo chair is ordered by a stripper. I just help make the wheels that can be pushed under the bamboo chair. With the wheels, it is easier to carry in and out."

Wen Shu nodded, it turned out to be the case.She just said that she has never seen her father do any bamboo craftsman work.

However, for Mrs. Sun's situation, can I try using Bingli Pocket?

According to the doctor, Mrs. Sun's Zhujue syndrome is caused by the poor circulation of blood vessels in the brain and blockage.As long as the blood clots in the stasis are scattered, it can be restored.

The wounds on her chest and abdomen were also bruises. Since Bing Lidou could heal her, it should also be able to heal Aunt Sun, right?

Taking ten thousand steps back, even if it cannot be cured, it will not be harmful to the body, so it is right to give it a meal.She lost her mother since she was a child, and Mrs. Sun took care of her a lot, taking care of half of her mother.

Now that she is seriously ill in bed, since she has a way, she should try it anyway.

Thinking of this, she hurriedly shared her thoughts with her father.

Father Wen only groaned for a moment before agreeing.Because of Mrs. Sun's illness, the Sun family has almost crossed half the sky. If it can be cured, he will be happy for them.

The two agreed, and after eating, they took two ice pears and went to Sun's house.

When the father and daughter arrived, the Sun family had just finished eating.The daughter-in-law of the Sun family, Xiao Sun, was sitting under the grape arbor in the yard to enjoy the shade. When she saw Wen Shu coming with a basket, she hurriedly got up and went to the front of the yard to say hello.

"Sister Ah Ning is here, but have you eaten yet?"

He asked this question deliberately.

Wen Shu smiled, and replied: "Just finished eating, the dishes brought back by Dad are all delicious, but sister-in-law's craftsmanship?"

The meal that their father and daughter ate today was brought back from the Sun family.

"It's good if my sister likes it. Something happened at home during this time, and I didn't bother to find my sister to play with. Uncle Wen just came over today, and I was so comfortable that I cooked two dishes myself. Let Uncle Wen Take it back for my sister to taste."

When she said this, Xiao Sun always had a friendly and kind smile on her face, as if the two of them had always been so affectionate.

But in the past, their relationship could only be regarded as casual.In the past when she came to Sun's house, although Xiao Sun did not speak harshly to her, but he only smiled politely, with a sense of alienation in his politeness.

Where does the enthusiasm of being so close to my sister-in-law today come from?
