Tiantang Splendid

Chapter 224 Baby
The filtering device was completed, and the servant who went to fetch the brine also returned.

He ordered people to skim off the turbid things in the middle layer and put them into a single basin. The ingredients in it were mainly unreacted lard and impurities, and a small amount of soap.

Fang Jun asked people to add the mixed brine into it and stir vigorously.

Not long after, the lard in the basin changed again and gradually solidified.

Fang Jun looked at the glistening lard, and was so excited that he remembered all the experiments he had done in the laboratory now!Adding caustic soda to lard will produce soap after the reaction, and adding hydrochloric acid will produce another substance.

wax!
That is, candles for lighting.

But in this day and age, wax is a luxury item, and the best wax is made from the substance secreted by white wax worms, or beeswax, which is simply sky-high!Even the most common ones are refined from high-quality oils, so they are often called butter waxes, expensive ones are not good!

The most common lighting for ordinary people is to use oil lamps!
As long as this lard wax comes out, it will be popular all over the world with its low price and quality far exceeding that of oil lamps!
After all, knowledge is power!
Fang Junmei is bubbling!Brother is so talented...

He quickly ordered someone to bring another piece of cotton thread.

Note that it is "cotton thread", not "cotton thread"!
Is there a difference?

The difference is huge!

Before cotton was introduced to China, China only had kapok for filling pillows and mattresses, but no cotton for weaving.Before the Song Dynasty, China only had the word "cotton" next to silk, but not the word "cotton" next to wood.

The word "cotton" only began to appear in "Book of Songs".

It can be seen that the introduction of cotton was at least during the Southern and Northern Dynasties, but it was mostly planted in the frontier.In the distant ancient times, the raw materials of our people's clothes were mainly silk, hemp and kudzu.Clothes and bedding to keep out the cold are also made of these materials, which can be filled with feathers of some animals and poultry.

At least in the early Tang Dynasty, cotton definitely did not appear in the Central Plains!
Inadvertently, Fang Jun found another business opportunity, and he was in a good mood!

Using my own teacup as a mold, I made a simple candle on the spot to light it.

The lamp is like a bean, but it is still very bright in broad daylight, and there is almost no black smoke when the oil lamp is lit!
A craftsman excitedly said: "Oh god! This is much cheaper than the cost of butter wax, and the quality is almost even better. This can make a lot of money!"

Fang Jun laughed, isn't this nonsense?The magazine in this oil wax has almost reached the lowest level of this era, so the soot after lighting is much less than that of ordinary candles, and the oil lamp is even more incomparable!

Of course, it's not over yet.

Fang Jun stared at the last half pot of "waste liquid" with burning eyes, this is the essence of saponification reaction!

These waste liquids contain a substance that is a hundred times, a thousand times more precious than soap and wax—glycerin!
Glycerin is a colorless, sweet, clear, viscous liquid that is an extremely important chemical raw material.Wide range of uses, almost covering most of the chemical industry.It has applications in food processing, pharmaceuticals, cosmetics manufacturing, industrial machinery lubrication, organic synthesis, plasticization, etc.

In the early twentieth century, glycerin was the main raw material for making explosives!

Of course, with the current technology and Fang Jun's level, this is basically a no-brainer...

But as long as there is glycerin, then everything is possible!Even if he can't make it himself, he has the best foundation, and it will be much easier for future generations to build on his foundation!

Moreover, these things are not useless now. After simple dilution and clarification, a glycerin sweet water can be extracted from the waste liquid.

I ordered the servants to remove the alkaline deposits, and what was left was sweet glycerin water, which was light yellow in color and had an unpleasant smell. All the craftsmen covered their noses, wondering what the smelly water was for.

Fang Jun asked a servant to slowly pour the stinky water into the filter altar that had been prepared long ago. After a while, water flowed out of the thin tube at the bottom of the altar. Not yellow water, but clear and transparent liquid.

"Uncle Dagen, do you still have the jar of peach wine you brought from home a few days ago?"

Fang Jun asked an old craftsman.

The old craftsman's face twitched, and his face was full of wrinkles like gullies: "Don't mention it, the old woman at home was not healthy last year, and when the wine was brewed in autumn, it was the daughter-in-law who handled it. The craftsmanship was not good, and the peach wine became more and more astringent. None of them were sold. The old man brought a pot to satisfy his hunger that day, but he only drank two sips..."

There are many wastelands in Lishan, and many places are not suitable for growing food. It is a pity to be deserted. Some old farmers planted some fruit trees, which bear fruit in autumn. They took them to the city to exchange for some money, but they could not sell a few. Some of them are reluctant to throw them away, so they will be put into tanks to make fruit wine.

Tang people are good at wine, and the sales of this kind of fruit wine are also good.

It's just that although this wine has a fruity aroma, it has a sour taste, which is really not very tasty.If the craftsmanship is poor, it will be hard to swallow.

Fang Jun said, "Go and get it."

The old craftsman froze for a moment, then nodded and said, "That's fine!" Then he turned and left.

Fang Jun looked at the clear stream gradually flowing out from the bottom of the jar, as if he saw a bunch of copper coins gushing out of the thin tube, exuding a golden light...

This clear glycerin water can extract pure glycerin with simple distillation, and now, it can also do a very important thing.

For example, peach wine or wine will produce something called tannin during the brewing process.No matter what kind of fruit is fermented, the tannins cannot be decomposed and remain in the wine. The naturally brewed fruit wine tastes bitter and astringent, which is extremely unpalatable.

Tannin is the culprit of the bitter taste of fruit wine, but it is indispensable when later generations pay attention to the quality of fruit wine.The amount of tannin determines the flavor, structure and texture of a wine.A fruit wine lacking in tannins will appear light in texture, without a sense of thickness.

In fact, tannin has anti-oxidation effect and is a natural preservative. It can effectively prevent wine from becoming sour due to oxidation, and keep long-term stored wine in the best condition.Therefore, tannins play a decisive role in the aging ability of red wine.A bottle of red wine in a good vintage may get better after ten years.

This is the power of tannins.

But what is needed now is fruit wine that can be brewed and drunk immediately. Who has the patience to seal it up and store it for ten or eight years?
Then you need glycerin water.

The glycerin in the glycerin water can decompose the tannin in the fruit wine and effectively remove the bitter taste in the wine.Moreover, because glycerin has a slight warm and sweet taste, it can also greatly improve the quality and taste of fruit wine, and it is an excellent fruit sprinkle additive.

As long as the bitterness of the fruit wine is removed, and then the wine is filtered and clarified, the sweet and clear fruit wine will definitely become a very popular wine.

Princess Gaoyang on the side had already forgotten about Fang Jun's neglect of her, let alone getting angry, and was completely shocked.

She stared at a pair of apricot eyes, watching Fang Jun toss and toss such a pot of stinky lard, and he was able to toss so many tricks, it is unbelievable!
Could it be that this person really knows the magic touch?
Fang Jun directed the servant to make a new filter device, and then boiled the half pot of glycerin water again.The boiling point of glycerin is higher than that of water, as long as the sweet water containing glycerin is heated to [-] degrees, and the water is evaporated, pure glycerin can be obtained.

Of course, the purity is definitely not good, but it is no problem at all to add fruit wine.

After a while, Uncle Lao Gen came with his jar of peach wine.

Fang Jun ordered someone to divide a jar of wine into ten portions, add different amounts of glycerin and a few egg whites, and record the amounts added, because he didn't know the best ratio, so he could only experiment like this.After stirring well, it was filtered and purified.

Portions of clear and translucent peach wine appeared.

Just looking at this color, it has risen by more than one level.

Then naturally, after experimenting one by one, I let Uncle Lao Gen taste it one by one. Anyway, this stuff is delicious and can't kill people.

Of course, Fang Jun himself must be beaten to death and would not drink this kind of semi-finished product made in the laboratory...

Princess Gao Yang came over and looked at Uncle Lao Gen's feat of "testing poison with his body" in confusion...

"Is this stuff really drinkable?" Her Royal Highness asked uncertainly.

"You can try it, the taste is very good!" Fang Jun encouraged, showing his big white teeth.

"Huh!" Princess Gao Yang wrinkled her small face, showing a disgusted expression.

Fang Jun looked at this beautiful and charming princess, and smiled, but his brain hurt...
