Whether it is tea eggs or braised pork, it brings silent changes to the people of Chang'an City.

These things have or have no effect on anything.

However, for the people of Chang'an City today, the emergence of these things has enriched life.

After listening to Wang Fugui's report, Li Kuan did not give any additional instructions.

Since the development of the Tang Dynasty, many things no longer need to be taken care of by himself.

This is not Li Kuan's style of doing things.

So Li Kuan went to the laboratory of Guanshishan Academy as always.

However, Xiao Yumi has also begun to follow Li Kuan these days and wants to go to the laboratory of the Chemical Academy to observe the experiment.

Li Kuan, who has seen Xiao Yumi's learning in new science these days, has no objection to Xiao Yumi who has come into contact with Guanshishan Academy's laboratory so early.

He even had a little more expectation.

Most genius scientists achieve success in life before they reach thirty years old.

According to the perspective of later generations, I think that if I graduated from university in my twenties and want to do scientific research, I must at least study for a graduate student.

Then you will be almost twenty-six years old.

If you study for a PhD, you will be older.

So it seems very difficult to achieve results within thirty years old.

Little do we know that among the outstanding scientists in modern human history, whether it is Einstein or physics masters such as Boer, most of the most important achievements in life were completed before the age of thirty.

Of course, with the accumulation of experience, my grades after the age of thirty will naturally not be bad.

"Aye, why is the workshop under the laboratory of the Chemistry Institute so remote?

The craftsmen working here are not very convenient, whether they are living or doing anything."

Xiao Yumi went to the Hongphosphorus workshop with Li Kuan today.

After more than ten years of development, Guanshishan Academy's current science and technology is changing with each passing day, and some new things appear every now and then.

Red phosphorus was successfully produced in the laboratory this year and then put into the workshop for production.

“Although this area is a little remote and there is no people around, it also means safety.

No matter what kind of chemical workshop it is, it is dangerous during the production process, and the Red Phosphorus workshop is no exception.

The purpose of concentrating these chemical production workshops in this area is to promote each other on the one hand, and to prevent chemical workshops from scattering in crowded areas.

Once something unexpected happens, you can avoid major damage as much as possible."

Li Kuan knows the power of various chemicals more than anyone else.

Now Datang's chemical industry is in its infancy and development stage and is far from advanced.

However, after so many years of accumulation, various common chemicals such as sulfuric acid, phosphoric acid, and nitric acid can now be produced on a large scale.

Metals such as tin, zinc, chromium, etc. have also been officially refined on a large scale.

In Li Kuan's opinion, the workshops that make these items are all sources of danger.

Therefore, it is necessary to carry out special management.

"Your Highness the Prince, our workshop produces red phosphorus, which is very safe. The workshop next to it that produces white phosphorus is something that needs special attention."

Rao Yongxiang, who accompanied Li Kuan to visit the workshop, added a sentence.

With the use of incendiary bombs and white phosphorus bombs in the Tang army, the production of white phosphorus has become relatively mature.

Naturally, there are also special white phosphorus workshops in Chang'an City.

"Have you tried this red phosphorus? If you use it to make matches, is it much better than white phosphorus?"

Fire is a necessary material for human survival. How to make fire has always been an important matter that concerns people's daily lives.

Although there are already many styles of lighters available for people to choose from.

But for ordinary people, the price of lighters is still too high.

Everyone urgently needs a cheap and easy-to-use ignition object.

Guanshishan Academy of Chemical Engineering naturally regards this task as a project that it must win.

Previously, Rao Yongxiang and his team had made a batch of matches using the flammable characteristics of white phosphorus.

However, the safety of these matches has great problems, and after they evaluated it, they dared not promote it at all.

Originally, the ignition point of white phosphorus is very low. As long as the temperature is slightly higher, it is possible to spontaneously ignite.

This match will definitely be placed in the stove and other places where it needs to be burned. The temperature in these places may exceed the ignition point of white phosphorus.

In this way, the matches turned from ignition to a source of danger.

Rao Yongxiang, who almost burned all the laboratory, decisively stopped the plan to build a white phosphorus match workshop.

After Li Kuan learned about this matter, Li Kuan immediately proposed another plan.

This led to the emergence of red phosphorus and the current construction of this workshop.

Once red phosphorus is mass-produced on a large scale, the production of matches becomes very simple.

Whether it is a small wooden stick or a sulfur, it is not a problem.

"Your Highness, your plan is really amazing. The matches you made are safer than any previous one.

The most important thing is not only not to worry about matches spontaneously igniting, but also retain the characteristics of easy friction and fire. It is definitely the best cheap ignition item and deserves great promotion."

As the dean of the School of Chemical Engineering, Rao Yongxiang has a good vision.

Such an inconspicuous match actually has great significance for the lives of the people of the Tang Dynasty.

In the future, matches are expected to become a must-have material for every household, just like salt.

And matches are consumables, and a match is needed to light a fire.

Over the past year, the demand for matches in the entire Tang Dynasty must be an astronomical number.

Considering overseas needs, it can fully support a huge match workshop.

The most important thing is that the cost of making matches is very high, and the profit margin will definitely not be low.

It is very likely that this will become a popular new foreign trade material.

"After the production of red phosphorus, the planning of the red phosphorus match workshop should be as bold as possible, build a larger scale, use steam engine equipment as much as possible, and use steam engine equipment as much as possible.

Of course, in the early stages, in order to launch matches as soon as possible, you can first produce some matches in the ready-made workshops in the workshop city to sell them.”

There is no need to hide it if there is good things.

Since the safe red phosphorus matches can be produced, the people must naturally use such good things as soon as possible.

"Please rest assured that we will be able to produce the first batch of matches as soon as next week.

Later, we will build a special match workshop simultaneously so that our match output can continue to increase in the future."

Rao Yongxiang naturally hopes that the larger the workshop he manages, the better.

According to the current situation, the Match Workshop is located under the Chemical Academy.

Although not all the money earned at the time is left in the Chemistry College, it is definitely a good thing for the funding of the Chemistry College.

After all, the Chemistry Academy needs to conduct various experiments and it costs a lot of money.

If you accidentally use up all the funds allocated by the college.

"Aye, will the appearance of this match put the lighter in crisis?

The price of a lighter is relatively high, and it may be enough to buy matches that have been used for several years."

Xiao Yumi suddenly asked a very special question.

Although the scale of the lighter workshop is not very large, its sales are very stable.

Especially during the foreign trade process, many maritime merchants will carry a box of lighters to sell to the sea.

And among the wealthy and wealthy merchants in Chang'an City, every household must have a lighter.

"The lighter is a lighter and a match is a match. Although the functions of the two of them are the same, the purchaser's object is almost completely different.

This is like the emergence of bicycles, which facilitates people's travel, but it will not have any special impact on the sales of four-wheeled carriages."

Li Kuan knew that even the lighters in later generations were already very cheap, before liquefied gas or natural gas became popular, the ignition items used in rural areas were generally matches.

It is basically enough to ignite one piece at a time, and a box of matches is enough for a month.

A box of matches costs only one or two cents, even ordinary people can afford it.

"It's good that there is no impact, otherwise it will be embarrassing at that time. Maybe how many people in Chang'an City will laugh at us."

Although Xiao Yumi is smart, it is obviously unrealistic to expect a teenage girl to have a mature mentality.

...

"Chong'er, is there any movement in the East Palace these days?"
