In order to practice pronunciation and articulation, she now tries to speak as much as possible whenever she wants to say something.

I will only say it in my heart if I have too much to say.

Situ Yuan teased her with a smile: "Guess?"

Xie Ying glanced at him sideways and refused to guess at all.

She didn't want to waste her energy.

Seeing that she was unwilling to cooperate, Situ Yuan had no choice but to continue, "This time, we can make a lot of money."

Xie Ying glanced at him suspiciously, but still refused to guess.

Situ Yuan had no choice but to give in. He reached out to open the box, took out the things inside, and put them directly in Xie Ying's face.

Xie Ying looked at the chubby face in front of her in surprise, then her eyes widened and her whole face quickly turned red!

"Mirror!"

Situ Yuan actually made a mirror and deliberately put it in her face!

Also, is there something wrong with this mirror? How can her face be that round?

She looked at Situ Yuan suspiciously, suspecting that the boy was doing it on purpose: "Funny mirror?"

Situ Yuan said sternly, "It's just an ordinary mirror. It's your face that's chubby, it has nothing to do with the mirror."

Xie Ying glared at him unhappily and continued to look at the mirror in front of her.

She soon discovered the problem and frowned, saying, "Not high definition."

Situ Yuan smiled brightly: "It's indeed not enough, because this is a tin mirror made of tin, neither an aluminum mirror nor a silver mirror."

Xie Ying's eyes widened in surprise. She only knew what silver, tin, and aluminum mirrors were. Could tin and aluminum also be used to make mirrors?

Situ Yuan smiled and explained to her, "The mirrors we look at have a layer of bright silver metal on the back of the glass, and then a layer of opaque paint is applied to seal it.

Tin, aluminum, and silver are all silvery-white metals, so they can all be used to make mirrors. However, tin's reflective power isn't as good as aluminum and silver, so the resulting mirrors are less clear.

But it's not without its advantages. Compared to silver, tin is much cheaper. Nowadays, it's impossible to refine metallic aluminum, so we can only make tin and silver mirrors."

Xie Ying understood immediately after hearing what he said.

Her eyes grew brighter and brighter, and she looked at Situ Yuan with a look full of ridicule: "How cunning! You've made the tin mirror now, are you planning to launch it first, sell it at a high price, and then release the better quality silver mirror, selling it at a high price while lowering the price of the tin mirror?"

People in this world still use copper mirrors, but copper is also a precious metal, so the copper mirrors made from it are naturally not cheap.

Mirrors are different from coal. People will not die if they don't look in the mirror.

Therefore, poor families would not afford to buy bronze mirrors and would just use water to look at their faces.

Another problem with bronze mirrors is that their surfaces oxidize easily. Once oxidized, the mirror becomes blurry and requires a professional mirror grinder to polish it.

It costs money every time you hire someone to polish your mirror. Those families who are not well-off naturally cannot afford to hire someone to polish their bronze mirrors frequently. They will wait until the mirror can no longer reflect people before polishing it.

Therefore, in general, the clarity of bronze mirrors is not as good as that of glass mirrors.

Xie Ying had a bronze mirror at home, and she had used it herself. Because of the lack of clarity, the faces in the mirror looked like they were filtered through a soft light and blur, which was quite interesting to look at.

She was just used to the high-definition mirrors of later generations, so she didn't like this bronze mirror that couldn't clearly reflect facial details.

It's nice to use it as a filter, but if you want to see clearly, this mirror can't do it.

Xie Ying picked up the tin mirror that Situ Yuan brought and looked at it carefully. The more she looked, the more satisfied she felt.

Although it is not as clear as a silver mirror, its clarity is far superior to that of a bronze mirror.

The key is that after buying it, you don’t have to worry about oxidation and blurring, nor do you have to hire someone to polish it, which saves a lot of money.

Xie Ying looked at the frame again.

The mirror frame is made of wood, has a handle, and the back is carved with patterns, which is very exquisite.

It is very light in the hand, not as heavy as a bronze mirror.
