Tiantang Splendid

Chapter 84 Don't do business?

His Majesty Li Er left angrily, without eating, Fang Jun would not waste it, he brought the hot pot prepared for His Majesty Li Er into the house, pulled Fang Quan, Lu Cheng and Fang Sihai around the table, Eat and drink.

At first, the three of them were unwilling, and the servants and the master ate at the same table. How could there be such a reason?However, Fang Jun couldn't keep pulling and pulling, so he had to sit down, both moved and apprehensive.

During the banquet, Fang Quan asked, "Erlang, you asked me to prepare something that day. You said you were going to put some nose rings on the cattle. When will you get them?"

Fang Jun just remembered this, because he was so happy when he heard that the glass was burnt out in the past two days, and he was so busy preparing for this tasting meeting that he forgot about it.

"That thing is very easy, but there is one thing missing, and we have to wait two days."

It is not difficult to put a nose ring on a cow, but alcohol is used to disinfect the wound in future generations. Now that there is no alcohol, at least a high-level liquor will have to be used. Otherwise, once the wound is infected, the life of the cow will be in danger...

These days, cattle are the most important means of production, and hardly one of them.

Moreover, he has had enough of the sour wine of the Tang Dynasty. Drinking can be like eating fruit. Who can stand it?

Distilled wine must be made out, although I dare not sell it, I can drink it myself.

When a modern person travels to ancient times, what is the biggest reliance?
Familiar with the historical process counts as one, so that you can hold your thighs, and there is almost no risk of standing in the wrong line.

Another is the vast amount of knowledge.

The dissemination of knowledge in ancient times could only rely on books, and the scope of dissemination was quite narrow.Especially before the Song Dynasty, because of paper, printing and other reasons, books were genuine luxury goods, and the number of original printed books was very small. If you want to read books, you basically rely on copying...

Coupled with the conservative ideology of the folk tradition of "teaching the apprentice to starve the master to death", it is better to bring technology into the coffin than to easily impart it. Natural knowledge, science and technology have been stagnant for a long time, even to the "I Qing Dynasty". At that time, there was a huge setback.

The Confucian doctrine of "emphasizing the way but not the weapon" is the biggest stumbling block hindering the progress of science and technology.

People with long-term wealth and smart minds all read the Four Books, Five Classics, and Eight Poems, but the research on science and technology has turned into "wonderful skills", which are despised by others. We smashed a piece of shit...

In modern times, it is completely different.

Academic exchanges around the world, the rise of the Internet, and the rapid spread of consulting have made it easier for people to access a variety of knowledge.

Simply put, the cost of acquiring knowledge has dropped significantly and the means have become wider and wider.

With 5000 years of history, mathematics, physics and chemistry literature, sitting at home behind closed doors, one can know the affairs of the world.

This is immeasurable for the cultivation of a person's level of knowledge and insight.

Just like Fang Jun, he doesn't know how to burn glass at all, but he just happened to have heard of it before, or even seen related posts on the Internet. According to the gourd painting, it is not difficult to burn it.

Let me ask, if you are an ancient person, where do you go to know these steps and the raw materials required?
Don't say no one knows, know and won't tell you...

Early the next morning, Fang Jun called seven or eight servants in Zhuangzi to prepare soap.

There is no problem with the materials for making glass products, but the difficulty lies in the production process and technical proficiency.

Fang Jun has never done this job before, and he can't do anything. He can only let the craftsman figure it out by himself.But he also made some suggestions, such as blowing on a long pipe, you can blow out a glass bottle...

Compared with glass products, soap is more difficult in terms of materials, but the production process is much easier, because soaps throughout the ages and dynasties are all rectangular, and it is enough to make a mold...

Fortunately, after more than a dozen servants' persistent experiments, caustic soda was finally formulated from soda ash and lime, and it did not explode.

Fang Jun just knew that glycerin reacted with some strong oxidants to turn into nitroglycerin, but he didn't know that it would be much more difficult to turn glycerin into nitroglycerin than to make soap from animal fats...

However, the expected nitroglycerin did not appear, but Fang Jun was a little worried about gains and losses. Although no one was killed, after all, there was one less weapon that could blow the city wall to the sky in an instant...

On the open space in front of the porcelain kiln where the glass was fired, a large pot was set up. The fire was burning hot, and the lard in the pot was already warm.

Fang Jun instructed a servant to pour the prepared caustic soda into it, and then kept stirring, a strange smell suddenly wafted from the pot.

At this point, remove the pot from the heat and keep stirring.

Until the lard and caustic soda are completely combined, add a small amount of salt water while it is still hot, this is called salting out, Fang Jun understands a little...

Then, the servant in charge of stirring was shocked by the vision in the pot. He pointed his finger at the pot, his eyes widened and his mouth opened wider, so he could stuff an egg.

When others saw his expression, they were naturally curious. They looked into the pot and found that an unexpected change had taken place in the pot. Locally, if it wasn't for the rapid ups and downs of the chest to prove that they were all alive, they would definitely be regarded as a row of statues.

Some ointment-like yellowish objects appeared in the pot.For people in the Tang Dynasty who had no chemical knowledge, it appeared out of thin air, and it was simply a fairy-like ability, which was too hard to imagine.

Continue to stir, the oil temperature gradually drops, the pale yellow sodium stearate cools and precipitates, floats on the upper layer of the solution, scrapes it off with a wooden board, pours it into the prepared mold, and after drying and molding, a bar of soap is made.

The residues in the pot were dissolved glycerin, salt and unfinished sodium hydroxide. Fang Jun didn't know what to do with it. It seemed that these things could not only make nitroglycerin, but also fertilizers?

Of course, he certainly won't, so he can only pour it out.

Industrial wastewater is one of the "three wastes", but this wastewater is an exception because glycerin can protect plants.Plants protected by glycerol can grow well on saline-alkali land, so there is no need to worry about environmental pollution.

The soap has been pressed into the mold, and it will only be completed after cooling and molding. Fang Juncai remembered one more thing. If you add some spices or something, is it just soap?
I scratched my head, but I was too lazy to do it, let's talk about it next time...

In fact, the quality of the soap he made in this way was very poor, with impurities such as glycerin still remaining in the soap, as well as a little pigment.

But who said that the entire Datang has no similar products compared?
If you compare goods, you have to throw them away. There is no comparison. Naturally, it is a good thing, so you don't need to throw it away...

Fang Jun stood with his waist pinched, feeling a sense of accomplishment, but he is a student of agricultural technology, and he actually started a chemical industry.
