Mercury is a metal that has been used by humans for a long time.

According to the literature, during the Spring and Autumn Warring States period, the Chinese began to use mercury, including dumping "mercury pools" in tombs, or using mercury to treat scabies, etc., with various and strange uses.

But there is no doubt that the people of the Tang Dynasty have long learned to use this kind of thing. Including mercury, including the form in which mercury exists in nature, that is, dansha.

In fact, not only Chinese, but also Westerners have been using mercury for a short time.

Western alchemists even believed that mercury was the embodiment of metallicity, an "element" that made up all metals. And the alchemists of the East, that is, the alchemists, are also very interested in mercury, and there is mercury in many elixirs of immortality...... Or the existence of dansha.

Therefore, as soon as Li Yuanjia said mercury, Han Cheng and the others immediately knew what it was.

Han Cheng, who was in the glass workshop every day, naturally nodded immediately, and said seriously: "Back to the king's words, we have used mercury!" It's just that although this kind of thing can be spread evenly, it is difficult to leave ......."

"Huh."

After listening to Han Cheng's words, Li Yuanjia chuckled and nodded.

Without the right method, mercury is indeed unlikely to stay

On top, after all, glass is smooth, and the refined mercury is a liquid, and it is a liquid that evaporates when heated.

So after pondering for a while, Li Yuanjia suddenly asked again: "So, have you tried mercury and other metals to work together?" ”

"Huh? Together? ”

Hearing this, Han Cheng was stunned, and Han Cheng didn't quite understand what the king meant for a while.

If the words metal and function were placed a few years ago, Han Cheng probably wouldn't have understood them, but after working in the glass workshop for a few years, and Li Zhong on the movable type side often met and chatted, he naturally understood.

I was surprised because I understood.

"Hehe, yes."

Looking at Han Cheng and the others with a look of surprise and dazedness, Li Yuanjia nodded slightly, and said with a faint smile: "A few days ago, I saw an ancient book from Da Shi, which said that mercury can be fused with some metals...... Have you ever thought of this? ”

"This ......"

Subconsciously frowning, Han Cheng frowned and thought carefully.

He didn't know much about mercury, and he just tried it and found that it didn't work, so he gave up immediately, and never thought about digging into anything...... What they now think of every day is to make all kinds of metals as smooth and smooth as possible, and then stick them on top of the glass to see the effect.

Every day is so busy that who has time to think about mercury again?

But now when he heard these words, Han Cheng's heart suddenly moved-with his understanding of the king, if it weren't for the other party's considerable certainty, he would not generally put forward such a specific opinion......

It's just that before Han Cheng could think about it carefully, a majestic voice sounded: "Han Cheng? Why don't you reply to the king's words? Darn! What are you thinking......

"Huh? The King forgives the sins! ”

After hearing this voice, Han Cheng was taken aback, and hurriedly knelt down: "The little one just thought of the king's words, so ...... The King forgives the sins! ”

"Alright, alright, get up!"

Frowning, Li Yuanjia was a little irritable: "You all shut up for me!" This king is here today to see how the mirror is doing, and also to find out if he can help a little, instead of asking you to kowtow to me...... Han Cheng, do you have an idea about what I just said? ”

"Back to the king, there is ...... With a little. ”

Swallowing a mouthful of spit, Han Cheng quickly nodded vigorously.

He could see that the king was not very happy at this time, and it was obvious that he had not said his thoughts in time just now. So after a pause, Han Cheng hurriedly said, "Great King, the little one also heard Li Zhong say that when they immersed some metals in mercury, they found that they had become different from before...... In that case, we can really give it a try! ”

Hearing Han Cheng say this, Li Yuanjia's eyes suddenly lit up: "Oh? Li Zhong: They also tried? ”

"Yes, King!"

Nodding, Han Cheng continued: "The little one remembers that Li Zhong once tried, and when he turned around, he went over there to ask ......."

"Waiting to turn around? Now go and ask! ”

Without waiting for Han Cheng to finish speaking, Li Yuanjia frowned and scolded: "Do you want to let this king wait until tomorrow...... Don't move, find someone in the past, now! ”

"Yes, King!"

Han Cheng confessed, and immediately grabbed a small guy next to him and explained it carefully for a while, and then the little guy ran out of the valley in a puff of smoke, while Li Yuanjia turned his eyes and glared at Han Lucheng fiercely, so frightened that the housekeeper quickly shrank his neck and didn't dare to make a sound.

Wasn't he the one who scolded Han Cheng just now?

However, Li Yuanjia didn't mean to pursue it, but frowned slightly, thinking carefully about what Han Cheng had just said...... Regarding the so-called reaction of mercury and other metals, to be honest, Li Yuanjia doesn't understand it very well, or even if he learned similar knowledge in his previous life, he should have forgotten it a long time ago, anyway, he can't remember it at all now.

But it doesn't matter, there are some things that he still remembers.

For example, the mirrors of the future used silver or lead, and the mirrors of ancient times used mercury...... It seems that there is another metal, Li Yuanjia really can't remember.

Since you can't think of it, just let Han Cheng try it the same way.

Anyway, the mirror that can be made by Venetian man, the technical content is definitely not too high, and it should not be a big problem to make it at the level of Datang.

The key is to find the right materials and use the right methods.

"Then the rest is to put in."

Thinking of this, Li Yuanjia couldn't help but sigh slightly, and subconsciously shook his head.

At the end of the day, this kind of experiment is really a trial and attempt, which means that it requires a constant investment of time, personnel and financial resources.

If Li Yuanjia wants to get results as soon as possible, then he must invest more manpower...... More people put in means more experiments in a short period of time, and more money is needed!

"To put it bluntly, it's money!"

Thinking that the next step would not only be to supply the glass of the palace, but also to continue to spend money to improve technology, Li Yuanjia was a little distressed...... In contrast, glass has been successful and will be able to make money after the New Year at the latest, but the mirror is ......

Hehe, God knows when you'll be able to make a plausible piece?

"Huh? That's right! ”

Thinking about it, Li Yuanjia suddenly remembered something, and quickly looked at Han Cheng again: "I remember, the book also said that once this mercury is hot, it may emit poisonous gas back, you have to be careful......
