Chapter 257 A new storm

The old Taoist priest Wang Kang discovered that he was a talent after the last mountain god incident.

How to say?

This person likes to study some strange and unconventional things, such as using vinegar to write drawings on white paper and then roasting them with fire to reveal them.

There is also a hot oil pan to detect objects. You can put your hand into the hot oil and take out the items at the bottom of the pan, and your hand will come out unscathed.

It seems magical to outsiders. This person has magic and supernatural powers.

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

The oil pan in "Oil Pan Fetch" is not actually filled with oil, but with a mixture of oil and vinegar.

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

.

Then heat the oil pan. The boiling point of vinegar is lower than that of oil. When you look at the pan boiling, the temperature is actually not high.

At this time, you will not get burned if you reach for the object.

All of these, as well as a few examples, were researched by the veteran Taoist priests themselves.

This is a bit awesome.

However, he has researched all these and used them to deceive and deceive, but he has to admit that they are also powerful.

Therefore, Wang Kang handed over this matter to him.

Outside the courtyard, there were soldiers standing guard and patrolling. When they saw Wang Kang arriving, they opened the door to welcome him.

After entering the courtyard, we obviously found something different. Although it is a residential house, it has been specially renovated to connect the two places. It is very large inside.

Both sides of the yard are filled with various transplanted flowers, including roses, peonies, orchids, lilies, bunches of red, peonies and many more.

The fragrance of flowers is wafting inside, and the fragrance is overflowing.

There were also specially hired women watering the flowers in the courtyard. When Wang Kang walked in, they all stood up and saluted.

"Master Kang,"

"You are here,"

They all know that this young master is the current owner of Xinfeng County.

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

"Supervisor Bai is in the backyard, do you need to report him?"

"No need, you go to work!" Wang Kang said and walked to the backyard.

There are several connected houses in the backyard. Wang Kang entered one of them. The old Taoist priest was busy in front of a vessel. Even Wang Kang entered without noticing.

Perhaps due to long-term habit, although the old Taoist priest is no longer doing Taoist work, he still wears Taoist robes.

"Lao Bai." Wang Kang called.

Hearing this, the old Taoist turned his head and said in surprise: "Hey, Master Kang is here."

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

"I have already made several kinds, and I am researching to see if I can find other essential oils."

The old Taoist continued: "The distiller you invented is really easy to use and very convenient."

"Haha, that's natural. Is there a finished product? Show me." Wang Kang asked.

"Yes, please wait a moment."

The old Taoist replied, and after a while he took out a small wooden box from the back room. He opened the wooden box and found three small bottles inside.

The bottle is crystal clear and contains several liquids, namely pink, red, and light blue.

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

Wang Kang picked up the small red bottle, pulled out the cork and smelled it. The fragrance of roses came out.

There was also excitement in his eyes. Under his guidance, the perfume finally came out.

It is also a design and invention aimed at women. Wang Kang always believes that women are the best place to make money.

In fact, people have been in the habit of incense since ancient times, such as fragrant powder, sachets, incense, fragrant soup baths, etc. In ancient times, there was also perfume, called rose water, also called Gu La water.

A kind of perfume distilled from rose flowers, it was introduced to our country from Iran, ā lā bó and other places during the Five Dynasties period.

By the Song Dynasty, people also mastered the technology of distilling perfume.

But there is no such thing in this era, because there is no distillation technology now.

However, Wang Kang had made it a long time ago, and he used it when he was making wine. He made high-strength liquor through distillation.

Now that you have the basic utensils, making perfume is actually very simple.

Perfume is made by mixing a certain proportion of plant essential oils with a portion of alcohol and purified water.

First pour about 60% pure water into the bottle, then drop in 10% alcohol, and the rest can be dropped into the essential oil. This is the standard ratio.

The only difficulty is the essential oils.

So how do you get essential oils? This requires distillation.

Collect the flowers at their best flowering period, dry them directly or slightly in the shade, and put them into a distiller to distill the essential oil liquid. This is the most original and simple method of making plant essential oils.

The next step is to mix the proportions, then cool and store them, and finally filter and purify them, so that the perfume is ready.

The transparent vial in which the perfume is placed is made of glass.

Glass is also a recent invention made by Wang Kang. In this era, the most commonly used material that is close to glass is colored glaze.

Glaze is quite expensive and a complete luxury product.

At that time, Wang Kang was renovating the heaven and earth, and most of his money was invested in this.

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

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

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

Due to its chemical composition and firing temperature, it will explode when exposed to hot water, so it cannot be used as household utensils at all.

However, during this period, such glass was not available, which resulted in the high price of colored glaze.

The materials needed to make glass include quartz sand, limestone, feldspar, and soda ash!

Quartz sand is a granular form obtained by crushing quartz stone, which is found in Xinfeng County.

Limestone and feldspar are even more common.

As for soda ash, it has been used since ancient times.

In fact, the things we see in daily life are very different from their production and raw materials.

Then there are the ingredients,

Mix various raw materials in appropriate proportions.

What to do next? This is similar to iron smelting, smelting.

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

Finally, let it gradually cool and anneal, and finally take shape.

Of course, it sounds very simple, but in the actual production process, it went through a lot of experiments.

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

However, wáng fǔ chén and the others are already studying this issue, and I believe it will be successful soon, because Wang Kang is building a new city and modern houses.

Just be prepared to use glass.
