Chapter 879 Tin

In the military room, there is also a huge nautical chart spread out with some boats on it. It seems that the generals are still reviewing the chart.

Su You stood at the side and took out the military records and flipped through them: "Four of you, you guys showed some amazing coordination this time."

Wang Shao smiled and said: "It's nothing that happened to me. It's all thanks to the three of them."

Su You was also happy: "This shows that princes have now been promoted from generals to commanders. Those who are good at fighting have no great achievements. Look at me, I have never been less handsome from the beginning."

Wang Shao was so angry that he rolled his eyes: "Show some face!"

Su You was not ashamed at all, and said to his companions: "Don't worry about the loss of ships. With the three strongholds on the east side of the strait, it will be a matter of minutes to recover the capital. This time you will completely obey Liu Shiheng's command."

, let me see the quality of soldiers. The intelligence branch will be established in Cochin Road next, and your positions can be promoted again."

Capturing intelligence is a routine operation of Su You and Wang Shao. It is often deployed ten or twenty years before military operations. With the help of these old Nanhai veterans, the intelligence branch is established in minutes.

However, the Song Dynasty's performance at sea was more powerful, so there was no need to covertly build the Tingfeng Pavilion and the Wangyu Pavilion, just set it up directly under the shogunate, blatantly.

What made the envoys even more happy was: "In order to reward you for your performance this time, the Cochin Transportation Department decided that for the thirty-three envoys who contributed ships this time, the Transportation Department will use their own pockets to compensate each of them with a state-of-the-art ship.

Meishan type schooner!"

The hall suddenly exploded. The ability of the schooner was obvious to all. The speed could reach up to fourteen knots, which was truly a thousand miles per day.

It can also sail against the wind, has flexible steering, high safety, and requires only a dozen sailors. The many benefits are self-evident.

After the sea route is safe, these ships can quickly travel around the South China Sea, providing information to the Song Dynasty and doing business at the same time. It is so beautiful to think about it...

When the envoys returned to the Song Dynasty, many of them had the heart of their homeland. They originally expected the Song Dynasty to settle down with a household registration, but they did not expect that Su Shaobao would give them such a reward.

One Meishan type now costs 3,000 guan, and thirty-three ships would be 100,000 guan, which is quite a big deal.

For Liu Shiheng and Wei Shou'an, Su You gave another round of incentives. Wei Shou'an was an old navy man and a former Jiaozhi general. It was necessary to be careful, but it did not prevent him from asking for merit and reward. I guess Zhao Xu would still

They will grant titles and fields, and a Jiedushi envoy may not be able to escape.

As for Liu Shiheng, he had performed very well in the Battle of Jiaozhi and this time in the Battle of Macheng. This boy is simply a master of stealing chickens. Wang Shao has already taken him under his name and is ready to train him well.

Su You said to Liu Shiheng: "Your Majesty likes heroic young men the most. You have seen the power of the new army. You are smart enough, but your foundation is too poor. If you are interested, you must first enter the Royal Institute of Technology to study artillery subjects.

Training, if you pass that level, you can become the commander of the new army. If you can't pass it, hehehe..."

From the observation tower on the top of the mountain, Liu Shiheng watched the whole battle process of the new navy. The scene of more than 300 old warships blocked in the bay and being attacked without any resistance made him full of admiration for the new firepower.

, of course I was overjoyed to get such an opportunity: "Thank you so much, Shaobao, for your support."

Su You nodded: "The Song of the Martial Arts of the Imperial Song Dynasty is the basic ethics of the New Army. If you want to join the New Army, you must ask yourself according to the martial ethics of the New Army."

"Wherever the country needs it, we must go wherever it is. Since I became an official, I have not been to Bianjing City very much. Instead, I have been to the southwest, northwest, Hebei, and southeast. Now I have even come to Nanhai, which is thousands of miles away from Bianjing City."

"You will be like this in the future. Don't think that you can come back and become a king after completing your studies. You may go to Liaodong, you may go to Mobei, you may go to the Qingtang Plateau, you may even go to the Southern Song Dynasty that was just discovered now.

"

"Do your part for this country and return this ability to it, so that it will not be afraid of foreign enemies, make it rich and stable, and let the relatives you care about and love can live a carefree life in this land.

That’s what we have to do.”

"Before such a lofty ideal, what does personal gain or loss count for a moment?"

Liu Shiheng nodded: "Don't worry, Shaobao, I've thought about it and remembered it."

As for Sun Neng being his disciple, there was nothing much to say. I praised him lightly and praised him mainly for his kindness in handing the wheel gun to Liu Shiheng for temporary use. However, this was still a violation of military discipline, and it was the same afterwards.

You have to collect the punishment yourself.

Sun Neng agreed nonchalantly, and Su You then asked: "Have you got the formula for Greek fire? Where did they get the oil?"

Wang Shao said: "I asked. On the way here, there is a large island called Centipede Island in the east coast. Mufuti discovered oil seedlings there."

Su You nodded: "That's ours. The navy can continue to extract the fierce fire oil, and that thing can also be of great use."

Wang Shao took a metal ingot and said, "We also found a lot of these in Macheng."

Su You took it, weighed it, and estimated the weight. This thing looked very familiar.

The flat glass used in colored mirrors is poured on the surface of the solution of this thing - tin.

Many people think that tin is poisonous, but it is not. It just makes people sick.

At low temperatures, the phenomenon of white tin transforming into gray tin is often called tin blight.

This phenomenon was discovered in the tinware sold to the Xixia people.

This thing has a wide range of uses. Like the "fool's gold" of pyrite, tin sulfide also has a golden luster. It is now a pigment used in ordinary paintings. For example, the New Year paintings sold by Sitong Company use this as gold.

What's more important is its oxide, which is white in color and is called "tin white". It is an important additive for Sitong Company to make porcelain, white emulsified glass, and enamel white fillings.

The air in the South China Sea is very corrosive. In addition to the advanced process of bluing, there is also a simple treatment method.

When steel and copperware are soaked in tin liquid for half an hour and then taken out, the surface of the metal parts will be plated with a layer of tin. This property can also be used to make tin sheets for cans.

If combined with "Lianshan tin", that is, antimony, to make an antimony-tin-copper alloy and use it to wrap bearings, friction can be reduced.

If it is made into an alloy with brass, a blowtorch can melt it. It is strong and corrosion-resistant. It is now widely used in Jiaozhi shipyards and weapons factories. This is today's welding rod.

There are two other things, lead type and tin foil. Let’s not talk about lead type. Tin foil is fine in dry Shaanxi, but in Jiaozhi it can be said that it is inseparable for a moment.

Nowadays, the tin foil and tin sheets used in Jiaozhi mainly come from Dali. Xiao Gao Xiangye is very resentful because he makes more money from tin-made tableware, wine sets, tea sets, furnishings, and stationery than from selling tin foil to Suyou.

Earn too much.

Previously, the annual tin output of the Song Dynasty was only 330,000 kilograms. After Su You went to Sansi for inspection, he found that there was still some antimony, and even some zinc and lead included in it. The real tin was 330,000 kilograms.

Not even a pound.

Su You tossed the tin ingot with a smile: "How many are there?"

"One hundred thousand catties."

With a clatter, the tin ingot fell to the ground: "How much?"

Wang Shao was a little nervous: "There are several warehouses, and... the bottom of the mountain here seems to be... full of this."

“Damn it—” Su You immediately became excited: “Take me to see it quickly!”

The warehouse was opened, and there were three entire warehouses filled with tin ingots.

The smelting of tin ore is very simple. You just need to mix coke and quartz sand into the furnace for firing. However, the current traditional process requires using a lead bar to guide the discharge port, so that the metallic tin will continuously flow out of the furnace.

Moreover, the melting point of tin is very low, more than 200 degrees, so it can be easily processed into metal blocks.

The purity of this batch of tin is extremely high, and the color is white and bright. Unlike the tin from the Song Dynasty, the Shi family had to use the method of inserting wood and blowing air to remove iron, and adjusting alum and salt to remove poison. In fact, it was to remove arsenic, lead, and add sulfur to remove copper.

Wait, after a series of repeated smelting, the black Song tin can be purified into pure tin that is as dazzling as silver.

Tin utensils made of such tin are now very high-end utensils, and their biggest uses are wine vessels and tea boxes for warming wine.
