As soon as Emperor Yong'an heard Chu Yan's words, he instantly understood his thoughts, and he sneered angrily: "You are really a bastard!" It's just farm tools, and I can't even look at them! ”

Chu Yan immediately complimented: "Father is right, it's just some farm tools, how can my father look at it?" It's Erchen's fault. ”

Emperor Yong'an snorted coldly disdainfully.

How did he think that Chu Yan suddenly changed his words: "Since my father is not rare, the farm tools produced will belong to the Su family, and my father has no opinion, right?" ”

"Put away your thoughts, I said, I don't like that little farm tool yet!"

What a bastard, could he, as the Son of Heaven, still care about his daughter-in-law's farm tools?

In fact, Chu Yan also felt that Emperor Yong'an should not be worried, but he didn't forget that not long ago, Emperor Yong'an was still thinking about Su Jinli's Liulifang.

This ironworks was too sensitive, and he didn't dare to directly ask for it to be classified as Su Jinli's private property.

But the farm tools produced in the ironworks can't be taken by people, right?

And so it was settled.

Emperor Yong'an was very unhappy with Chu Yan's attitude, but he didn't know that it wouldn't be long before he would be slapped in the face!

Building an ironworks is not an easy task.

Iron is too important, and the art of steelmaking is even more secretive, and must not be leaked out.

Therefore, the walls of this ironworks must not be missing.

In addition to this, blast furnaces and workshops had to be built.

Fortunately, with cement, it has become much easier to build a factory, as long as the foundation is laid and more masons are found, it can be built in half a month.

Chu Yan knew that Su Jinli attached great importance to farm tools, and was worried that the spring ploughing would be delayed, so he relied on his identity as the king of Qin to let people produce drawings as quickly as possible, and then asked the people below to find a large number of masons to work overtime to trim the ironworks.

The ironworks are built next door to Liulifang, and there is a coking mill under construction next to it.

The coking workshop was built before, and this thing was not as sensitive as the ironmaking workshop, so after Su Jinli had a plan, he let people start repairing it.

However, she would have thought of building this coke mill thanks to the crown princess Jiang Luan.

She understands the truth of shooting the first bird, if it weren't for Jiang Luan's step-by-step pressing, let the palace maid Chunlan destroy Queen Zhang's flowers to blame her, and there was another incident with Mama Zhou.

She wouldn't have thought of building a coke mill yet.

It happened that high temperature was also needed to burn the glaze, so she built the coking workshop next to the glaze mill. In this way, the coke smelted in the coking workshop can be directly pulled to the glass mill for use.

Now there is an iron-making mill, and the coke burned in the future can also be used to make iron.

However, once the three workshops were built, the land was basically occupied.

Emperor Yong'an originally rewarded Su Jinli with a thousand acres of land, but now there is nothing left of the flat land below except for the Treasure Mountain.

The construction of the ironworks and coking mills did not affect the craftsmen in the glaze mill in the slightest.

Today, Liulifang has divided into several workshops, each responsible for different work.

For example, those who burn mirrors, those who burn glass windows, and those who burn glass and glass jewelry.

The workshop also has a strict system of welfare and rewards and punishments.

As long as they have made meritorious contributions, they will be given bonuses according to the size of their merits.

For example, the mirror made by Su Jinli can be rewarded as long as it is done.

Stimulated by the appreciation of silver, on the day of the start of the ironworks, the craftsmen finally succeeded in making the mirror that Su Jinli wanted!

After the mirror was ready, the steward of Liulifang couldn't wait to take the inlaid mirror and personally went to the Qin Palace's mansion to see Su Jinli.

As soon as Su Jinli heard that the mirror was ready, she immediately saw him.

This steward was arranged by Chu Yan, but when he faced Su Jinli, his attitude was very respectful.

After entering the house, he saluted respectfully, until Su Jinli gave him a seat, and he didn't dare to look up at Su Jinli the whole time.

just handed the box he brought to Cinnabar and asked her to hand it over to Su Jinli.

When Cinnabar held the box and sent it to Su Jinli, Su Jinli saw that there were two mirrors lying quietly in the box.

Both mirrors are only the size of a palm, and the mirror is oval in shape.

The mirror on the left is framed in brass, and the mirror on the right is made of gold.

Because the two mirrors are placed together, the contrast is particularly noticeable.

As long as you are not blind, you can easily see that the mirror on the right is much brighter and clearer than the mirror on the left.

The mirror on the left is slightly darker in comparison.

This is actually due to the fact that the light reflection ability of tin amalgam is not strong.

So it doesn't look bright enough.

If you look at the mirror on the right, it's obviously much superior.

It is conceivable that if you put these two mirrors together when you sell them, then even a fool may be able to see which mirror is better.

It can be used to stimulate consumption.

Su Jinli was excited.

She couldn't help but get excited.

In order to make this mirror, she broke her heart!

At the beginning, when she asked Liulifang to make mirrors, she deliberately chose four silver-white metals to make mirrors, making herself seem to be a layman.

The four metals are mercury, lead, tin, and silver.

However, after the craftsmen tried, they quickly eliminated the metal of lead. Because lead is easy to oxidize and blacken, and after reacting with mercury, it will become very rough, and it cannot be made into a mirror at all.

So in less than a day, the four mirrors that Su Jinli originally asked for were only two in the end.

One is a mercury mirror made of tin and mercury, and the other is a silver mirror made of silver mirror reaction.

However, the effect of mercury mirrors is significantly not as good as that of silver mirrors.

It can be used as a cheap mirror to occupy the low-end market.

Bronze mirrors are not cheap, not to mention that this thing has to be repaired frequently, how can ordinary people afford to use it?

Therefore, many people directly use the basin of water as a mirror.

If the mercury mirror is sold at a low price, there must be many people who are willing to buy it.

In addition, mirrors made of mercury and tin have long been available, and some copper mirrors will do the same.

The method is to cover the surface of the copper mirror with a thin tin film and then apply mercury. When mercury and tin interact, a thin film of tin amalgam is formed on the surface of the copper mirror, which is firmly adhered to the top and used to illuminate people.

It's just that mercury is toxic and volatile, and the mirror that comes out of this way will become more and more blurry after a short time, and it needs to be repaired frequently.

Or directly polish the copper mirror to be extremely smooth, and it can also shine on people. However, after the copper mirror is polished, the surface will oxidize after being in contact with air for a long time, and it will also become more and more blurry, and it needs to be continued to be polished.

Nowadays, it is just a matter of replacing the copper mirror with transparent glass.

Such a simple exchange, of course, is not difficult for those mirror makers.

However, it still didn't go well.

After the craftsman made the mirror according to the old method, Su Jinli found a very serious problem.
