"Masters, you have to stick this tinfoil as flat as possible. There shouldn't be any bubbles or anything like that!"

Looking at several royal craftsmen who were using gilding techniques to affix thin tin foil to one side of the glass plate, Wang Bing worriedly spoke again and warned.

With the help of the little girl, Wang Bing was completely freed from the crisis of his prince's palace turning into the prince's consort's palace. After bringing some materials back to Yongnian's palace, he started his great cause of turning glass into 'gold' the next day.

"Don't worry, Lord Marquis. The gilding craftsmanship of the little people is passed down from generation to generation, and there will never be any mistakes!"

Although it was the first time for this glass plate to be gilded with tin, several gilding craftsmen were quite confident in their ancestral craftsmanship.

In fact, these gilt craftsmen who were selected into the royal family were really good at craftsmanship. It didn't take long for these people to successfully stick tin foil on several small pieces of flat glass made by the blowing method.

"Well, it's not bad! The craftsmanship of these masters is really not impressive. This tin foil is really stuck together perfectly!"

Looking at the flawless glass plate in his hand, Wang Bing felt relieved and nodded with satisfaction.

"Husband, what are you doing?"

Just when Wang Bing was holding a piece of glass plate with tin foil and admiring the craftsmanship of these gilding craftsmen, at some point, the female instructor also came over with Xiao Lian.

"Haha, wife, what do you think this looks like?"

Picking up the glass plate with tin foil in his hand and raising it in front of the female instructor, Wang Bing said with a mysterious smile.

"Master, are you going to use this as a mirror?"

However, before the female instructor could speak, Xiaolian on the side spoke with some uncertainty.

"Xiao Lian is smart. The young master wants to use this glass to make you the clearest mirror in the world!"

At this time, Wang Bing stopped teasing the mystery and directly announced the answer.

"Husband, can you really make these transparent glass plates into mirrors?"

Hearing that Wang Bing really planned to use this transparent glass plate as a mirror, the female instructor suddenly showed an expression of disbelief.

In fact, not to mention the female instructor, even the gilding craftsmen who were pasting the tin foil were surprised when they heard that Wang Bing was making mirrors.

You know, even though they have pasted the tinfoil perfectly, the glass plate with the tinfoil on it can barely reflect the human figure. The effect is much worse than that of a bronze mirror, let alone

What can I say about the clearest precious mirror in the world?

"Haha, why, don't you believe in being a husband? Just don't be reluctant to let go when the time comes!"

Looking at the suspicious look on the female instructor's face, Wang Bing joked with confidence.

…

"Be careful, handle it gently, don't break it!"

After finding a utility room in the house away from the small courtyard and cleaning it out, Wang Bing directed several servants to neatly lay out the glass plates with tinfoil on them, all with the tinfoil side facing up.

"Okay, wife, go out and wait for me outside!"

After laying out these semi-finished lenses, Wang Bing drove out together with the female instructor and Xiao Lian.

"Husband, Xiaolian and I will stay here to help you!"

The female instructor, who was full of curiosity, was not willing to go out at this time, so she decided to stay under the pretense of helping.

"No, this mercury is highly poisonous. You are pregnant now. Be obedient and go out and wait for me!"

Although the female instructor showed some reluctance, Wang Bing resolutely drove the two girls out.

In fact, compared to the method of using mercury to dissolve tin to form a mixture of mercury and tin to coat the glass, the silver plating process is safer.

It's just that it was too difficult for Wang Bing to make silver nitrate in this era. So he had no choice but to use the simplest, but not very safe, mercury mirror-making method.

"Crack!"

When Wang Bing covered all the mercury on the tinfoil-covered mirrors and went out, with a soft sound, an iron general locked the entire utility room.

"Husband, is this okay?"

Looking at the locked utility room, the female instructor couldn't help but look over expectantly.

"It's still early, it will take at least a month!"

Favoringly scratching the bridge of the female instructor's straight nose, Wang Bing immediately took her and left the place quickly.

…

"Husband, today is one month old!"

On this day, when the first ray of light in the morning shone through the window into the room, the female instructor could not wait to urge her in Wang Bing's ear.

"Daughter-in-law, please sleep a little longer, the mirror won't run away!"

In the warm quilt, with his arms around the female instructor's warm and delicate body, Wang Bing was reluctant to get out of the quilt.

"Husband~"

Seeing Wang Bing lying in bed, the female instructor lay in his ear and whispered seductively.

"Little goblin, you just rely on the fact that you are a protected animal and I dare not touch you, right? See how I 'take care of' you in the future!"

How could Wang Bing endure this after being able to see whether he could eat or not for so long every day? When he raised his hands in surrender amidst the coquettish voice of the female instructor, he turned over and was about to jump out of bed.

"Husband, let's go look at the precious mirror first. It won't be a big deal for me... Husband, don't you want to try the Hanlin style..."

Stretching out a pair of jade arms to wrap around the neck of Wang Bing, who was trying to escape from the bed, the female instructor once again whispered seductively into Wang Bing's ear.

"Ah? Wife, aren't you always... Hehe, forget it, just in case..."

However, despite what he said, his body was honest. After receiving such a charming promise from the female instructor, Wang Bing was still sleepy at this time. He lifted the quilt, grabbed his clothes and quickly put them on!

"Let's go, daughter-in-law, my husband will show you the precious mirror!"

…

"Well, it's not bad, the effect is better than expected!"

After some inspection, there were a total of more than 20 lenses. Except for two that failed because the tinfoil was too unevenly dissolved, the rest had slight flaws at the corners at most, and they only needed to be re-cut.

.

"The clarity is okay, but the brightness is a little bit off!"

Looking at his clear face in the mirror, Wang Bing couldn't help but frown slightly.

There was no way, the mirrors he had seen in his previous life had all been silver-plated, and their brightness was certainly much better than the mirrors made by melting mercury into tin.

However, compared to the commonly used bronze mirrors, even this mercury mirror, which is slightly less bright, is many times stronger than the bronze mirror.

"Husband, what happened? Did you succeed?"
