Chapter 257

Since the last mountain god incident, Wang Kang has found that he is a talented person.

How to say?

This person likes to study some strange and unconventional things, such as writing pictures on white paper with vinegar, and then baking them with fire, which will show up.

There are hot oil pan detection, hand into the hot oil to take out the bottom of the pot items, hand out intact.

It seems amazing to outsiders. This person has magic and powers.

In fact, it's not at all. The principle is very simple. It uses different objects with different density and boiling points.

In fact, the oil pot in "taking things from oil pot" is not filled with oil, but with a mixture of oil and vinegar.

However, because of the high density of vinegar and the low density of oil, when the two are mixed, the vinegar sinks to the bottom and the oil floats on the top. It looks like a pot of oil is filled. In fact, there is only one layer of oil floating on the top.

Then heat the oil pan. The boiling point of vinegar is lower than that of oil.

At this time, I will not burn my hands.

There are still a few examples of this, all of which were studied by the old Taoist himself.

This one is a bit powerful.

However, he found out that these were all used to deceive and abduct, but he had to admit that they were also powerful.

Therefore, Wang Kang left the matter to him.

Outside the courtyard, there were soldiers on guard. Seeing Wang Kang coming, they opened the door to welcome him.

After entering the courtyard, it is obvious that it is different. Although it is a folk house, after special transformation, the two places are connected, and the inside is very large.

On both sides of the yard, planted with a variety of transplanted flowers, roses, peonies, orchids, lilies, a string of red, peony and so on.

In it, the fragrance of flowers is scattered and overflowing.

There are also specially employed women in the courtyard to water the flowers. When Wang Kang came in, they all got up to salute.

"Master Kang"

"here you are"

they all know that this young master is the master of Xinfeng County.

"Where's Lao Bai?" Wang Kang asked.

"Director Bai is in the backyard. Do you need to inform me?"

"No, you work!" Wang Kang said a word, then walked to the backyard.

There are several rooms in the backyard. Wang Kang enters one of them. The old Taoist is busy in front of a utensil. Even Wang Kang doesn't notice.

Maybe it's a long-term habit. Although the old Taoist is no longer doing Taoist work, he still wears Taoist robes.

"Old white." Wang Kang called.

Hearing this, the Taoist turned his head and said, "ah, Master Kang is here."

"How's the research going?" Wang Kang asked and walked up to him.

"has made several kinds. I am studying whether I can find other essential oils."

"The distiller you invented is really easy to use and convenient," he said

"Ha ha, it's natural. Is there any finished product? Show me. " Wang Kang asked.

"Yes, just a moment."

The old Taoist answered. After a while, he took out a small wooden box from the inner room. He opened the box and placed three small bottles inside.

The bottle is crystal clear and contains several kinds of liquid, which are pink, red and light blue.

"Kang, this is the perfume you want to make," said the old way. "I have tried it, and the effect is excellent."

Wang Kang picked up the red bottle, pulled out the cork and smelled it. A fragrance of Rose came out.

his eyes also excited, under his guidance, perfume finally came out.

It's also a design invention for women. Wang Kang always believes that women's money is the best to earn.

in fact, people have the habit of incense since ancient times, such as powder, Sachet, incense, soup, bath, etc.

a perfume distilled from rose flowers. It was introduced into China in the Five Dynasties from Iran and Arabia.

in Song Dynasty, people also learned the technology of distilled perfume.

But in this era, there is no distillation technology.

but Wang Kang had already made it. He used it when he was making wine and brewed a high degree of Baijiu by distillation.

basic containers are available, actually making perfume is very simple.

perfume is made from a mixture of plant essential oil plus a portion of alcohol and purified water.

first pour about sixty percent of the pure water into the bottle, then pour ten percent alcohol into the bottle, and the rest can be dripped into essential oil. This is the standard ratio. The only difficulty for

lies in essential oils.

how did the essential oil come from? That's distillation.

Collect the best flowering flowers, directly or slightly dry in the shade, and then put them into a distiller to produce essential oil liquid. This is the most primitive and simple way to make plant essential oil.

then mix and mix, then cool and store, and then filter and purify.And the transparent bottle for perfume is made of glass.

Glass is also a recent invention made by Wang Kang. In this era, the glass used is mostly close to glass.

Glass is quite expensive. It's a complete luxury.

At that time, most of Wang Kang's money was invested in the decoration of heaven and earth.

Therefore, when the conditions were ripe, he presided over the invention of glass.

In fact, glass also existed in ancient times. In the Northern Song Dynasty, commercial glass appeared and began to become an industrial material. In the early Qing Dynasty, optical glass was made to meet the needs of developing telescopes.

However, the ancient glass in China has always been a relatively simple low-temperature lead barium glass.

Because of the chemical composition and firing temperature, it can't be used to make living utensils.

However, in this period, there is no such glass, which will cause the high price of glass.

The materials needed for making glass are quartz sand, limestone, feldspar and soda ash!

Quartz sand is a granular form of quartz stone after crushing and processing, which is found in Xinfeng County.

Limestone and feldspar are more common.

Soda ash has long been used in ancient times.

As a matter of fact, we can see things in our daily life for a long time.

Then there are ingredients,

mix all kinds of raw materials in proper proportion.

And then what? This is similar to smelting iron, melting.

The prepared raw materials are heated at high temperature to form a uniform and bubble free liquid glass, and then the molten liquid glass is transformed into a solid product with a fixed shape.

Finally, let it cool and anneal gradually, and finally form.

Of course, it is very simple. In the actual production process, we have experienced a lot of experiments.

For example, now we can only make some small bottles and cans, and the large-scale glass has not been successful, because of the lack of suitable molds.

However, Wang Fuchen and his colleagues have been studying this problem, and they believe that it will be successful in the near future, because Wang Kang is ready to use glass when he builds a new town and modern houses.

and glass can bring him huge wealth, and the development of perfume will definitely lead to a new storm.
