I was the emperor in the Ming Dynasty

Chapter 295 Removing Glass Impurities
In fact, a simple primitive lathe is not worthy of Li Tian's excitement.

But this is the first time he has seen the energy contained in the chests of the real elites of this era.

How could he be unhappy, how could he not be excited.

Only then did he truly understand that people in this era are not lacking in creative talent, but simply have no suitable place to display it.

If you study it carefully, you can actually know it.

Those who can be officials are the elites who are not Han Chuang who have studied hard for more than ten years, and then passed through layers of cruel elimination.

Regardless of their IQ or talent, they have all been tempered layer by layer. Compared with the millions of college students in the future, they are not in the same breath.

It's a pity that once they entered the officialdom, they began to rack their brains to figure out the so-called way of being an official in order to climb up. They had a talent and a smart head, but they used them in the wrong place.

And Li Tian founded the Tiangong Institute and Tiangong Bureau, so that their talents and learning were really released.

Going on like this, I'm afraid it won't take many years for Tiangongyuan to become a place that gathers the brightest sparks of wisdom in the entire Ming Dynasty.

It was precisely because Li Tian saw this hope that he was so excited and excited.

Although the lathe is just a small thing, the meaning it represents is not simple.

First of all, by creating the lathe, we can know that in this era, some people have been enlightened and started to create things that did not exist.

Secondly, there are many things that can be derived from the lathe.

Whether it is used to produce agricultural tools or to manufacture magical weapons such as matchlock guns, it can greatly improve efficiency.

It may not take ten years. After countless improvements and additions, the lathe will one day evolve into a comprehensive platform with extremely powerful functions.

As long as a person's brain is strong enough, there are many things that can be made with it.

……

After the excitement, Li Tianyou began to read the remaining booklet.

Although this brochure is also from Zhou Town, the content is about the progress of glass firing.

According to the excerpt, after half a month of experimentation, Wang Chen and the others have fired many colored glazes.

The only downside is that there are still a lot of impurities in it, and they haven't thought of a way to make it crystal clear.

Li Tian had nothing to do about it.

The only way he could think of was to add something like sulfuric acid to the liquid glass to dissolve those mineral impurities.

It's a pity that although there are things like aqua regia in this era, not only the concentration of that thing is very low, there may be more impurities in it than glass, so it's useless at all.

Since these impurities cannot be dealt with in the later stage, we can only ponder on the raw materials.

Sand that can be fired into glass is generally sand that contains a lot of quartz.

The reason why sand has impurities is that the surface of quartz contains a lot of thin film iron.

In fact, this part is also easy to handle. There are two ways to effectively remove these impurities.

The first is water washing. Repeated washing can not only remove the soil in the sand, but also dissolve most of the iron minerals.

The second method is scrubbing, which is mechanical or manpower, which constantly stirs the sand, so that the originally rough sand particles will rub against themselves.

In this way, the residual minerals on the quartz surface can be greatly destroyed.

Finally, wash with water several times to filter out these impurities.

After repeated several times, at least more than half of the impurities can be removed.

Li Tian also knows that in this era, it is impossible to fire glass that is as clean and transparent as the later generations.

But his requirements are not too high, as long as he can produce glass at the level of the European 67th century, he is already satisfied.

Write down your own thoughts and opinions, and hand them over to Wang Fu for him to convey.

Finally, all the backlog of things these days have been dealt with, Li Tian is also exhausted.

However, compared to dealing with tedious and boring government affairs, Li Tian's nature is still very high when dealing with such things.

Whether it is the increasing deposits of the royal bank or the workshops that are getting more and more money, the changes brought about are very significant and can be reflected in front of him.

Today, not only did the workshop bring him good news, but the Tiangong Institute even gave him a huge surprise.

He thought to himself, "If he could receive one or two such good news every day, he would be willing to spend all day in these memorials."

……

See there is still a lot of time until the afternoon.

Li Tian stepped in and came to Kunning Palace.

Because the workshop can bring Li Tian almost 1000 taels of net income every day.

Although a part of it is retained in the hands of the workshop for further expansion of production in the future, there are still hundreds of miles of silver that can fall into the hands of the queen.

The queen's life during this time can be regarded as very luxurious.

In the past, every time she rewarded palace maids and eunuchs, it was at most three taels or five taels.

The other noble concubines knew that the queen had suddenly become rich, and they all liked to play with the queen when they had nothing to do.

It's not enough to open your mouth to ask the queen for some money, but you can still ask for some good things like jewelry and brocade.

Li Tian hadn't entered yet, the queen and several concubines who were present at this time hurried out to greet him.

Waved away their salute.

The queen stepped closer to Li Tian's side, and said in a reproachful tone,
"Your Majesty has been busy for three days, why don't you take a good rest!"

Seeing that her face is radiant these days, Li Tian seems to be several years younger again. He couldn't help feeling hot in his heart, and no matter how many people were present, he put his arms around her small waist and said with a strange smile,
"You don't know my physique, let alone three days, so what if it's seven days and seven nights."

Knowing that what he said was not the same as what she said, the queen blushed and quickly broke free from Lushan's claws.
"Your Majesty, what are you talking about? The younger sisters are still here."

The other concubines seemed to be used to Li Tian and the empress flirting, all of them covered their mouths and snickered, and none of them came to help her.

"Wahhaha, beauty, it seems that you are doomed today, why don't you just follow the widow!"

The queen was so ashamed, she ran away with a coquettish smile while panting and said,

"Your Majesty, don't make trouble, I have something important to tell you."

After running a few steps, she was caught by Li Tian, ​​who was no longer what she used to be. He held her delicate body in his arms, and said with a look of love,
"Ling'er has something to say, just say it, I'm listening."

The queen struggled several times but couldn't break free, so she was grateful for saying what she wanted to say, trying to distract Li Tian.
