Chapter 879 Tin

In the military room, there are still huge charts, and some small boats are placed on them, and it seems that the generals are still reviewing.

Su You stood on the side and took the military record and flipped through it: "Four, you guys have played a god this time." ”

Wang Shao smiled: "It's nothing to do with me, it's the great work of the three of them." ”

Su You Yele: "This shows that the prince has now been promoted from a general to a handsome talent, and those who are good at fighting have no outstanding merits, you see me, I have never been handsome from the beginning." ”

Wang Shao rolled his eyes angrily: "Ask for face!" ”

Su You was not ashamed at all, and said to his companions: "Don't worry about the loss of the ship, with the three strongholds on the east side of the strait, it is a matter of minutes to get back the capital, this time you completely obey Liu Shiheng's command, let me see the quality of the soldiers." The next step in Jiaozhi Road is to set up an intelligence sub-division, and your positions can be promoted again. ”

Grasping intelligence is the routine operation of Su You and Wang Shao, which is often deployed more than ten or twenty years before military operations, and with the help of these old fritters in the South China Sea, the intelligence division is established, and it is a matter of minutes.

However, the performance of the Great Song Dynasty at sea was even stronger, so there was no need to hide what to do to listen to the wind and forget the rain pavilion, and it was directly set up under the shogunate, which was blatant.

The envoys were even more happy: "In order to reward you for your performance this time, the Jiaozhi Transshipment Division has decided that the 33 envoys who contributed to the sea vessels this time will be compensated by the Transshipment Division from their own pockets to each of them with a latest-style Meishan-type schooner!" ”

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

It can also sail against the wind, steer flexibly, and has a high level of safety, requiring no more than a dozen sailors, and many benefits are self-evident.

After the sea route is safe, these ships can quickly travel to and from various parts of the South China Sea, providing intelligence to the Great Song Dynasty, and doing business by the way, which is beautiful to think about......

The envoys returned to the Great Song Dynasty, many of them with the heart of their homeland, and originally expected that the Great Song Dynasty would settle down with a household registration, but they didn't expect Su Shaobao to give them such a return.

A Meishan type, now costs 3,000 guan, and 33 ships are 100,000 guan, which can be called a big deal.

For Liu Shiheng and Wei Shouan, Su You is another reward, Wei Shouan is an old sailor, and he is a former Jiaozhi general, it is necessary to be vigilant, but it does not prevent him from asking for merit and promotion, it is estimated that Zhao Ji will also give the first, give Xuntian, and I am afraid that I will not be able to run away.

For Liu Shiheng, in the battle of Jiaozhi and this battle of Macheng, his performance was quite eye-catching, this baby is simply a master of stealing chickens, Wang Shao has already included him in his name, and he is ready to be trained.

Su You said to Liu Shiheng: "Your Majesty likes the heroic young man the most, you have already seen the power of the new army, you are smart enough, but the foundation is too poor, if you are interested, you must first enter the Royal Institute of Technology for relevant training in artillery subjects, and then you can pass the level before you can become the commander of the new army, if you can't pass, hehehe......"

Liu Shiheng watched the tower on the top of the mountain, and watched the battle process of the new-style navy with all his beards and tails, and the scene of more than 300 old-style warships being blocked in the bay and being critted without resistance made him full of admiration for the new firepower, and he was of course overjoyed to get such an opportunity: "Thank you for your support." ”

Su You nodded: "The Song of Emperor Song Wude is the basic ethics of the new army. If you want to join the new army, you must demand yourself from the martial virtues of the new army. ”

"Where the country is in need, I have to go there, I have been out so far, Bianjing City has not been much in it, but the southwest, northwest, Hebei, southeast, have run all over, and now even come to the South China Sea thousands of miles away from Bianjing."

"You will be like this in the future, don't think that you can come back to be the king of the soil after completing your studies, you may go to Liaodong, you may go to Mobei, you may go to the Qingtang Plateau, and you may even go to the Southern Song Continent that has just been discovered now."

"Doing our duty for this country, giving back this ability, so that it is not afraid of foreign enemies, so that it is rich and stable, so that you can care for and love your loved ones, and be able to live a carefree life in this country, is what we have to do."

"In the face of such lofty ideals, what is the gain or loss of personal honor and disgrace for a while?"

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

As for Sun Neng's own disciple, there is nothing to say, he praised him lightly, and focused on praising him for handing over the wheel to Liu Shiheng for temporary use, but this is still a violation of military discipline, and he has to be punished himself afterwards.

Sun Neng agreed curtly, and Su You 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 big island called Centipede Island in the open sea to the east, where Mufuti found oil seedlings. ”

Su You nodded: "That's ours, the water master can continue to refine the fierce fire oil, and that thing can also be of great use." ”

Wang Shao took a metal ingot: "We also found a lot of this in Macheng. ”

Su You took it and checked it, and estimated the specific gravity, this thing is too familiar.

The flat glass used for the glass mirror is poured out of the surface of the solution of this thing—tin.

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

At low temperatures, the conversion of white tin to gray tin is often referred to as tin plague.

This phenomenon was found in pewter vessels sold to the Tangut people.

This thing is very versatile, like the "silly gold" of pyrite, tin sulfide also has a golden luster, and now it is a pigment used in ordinary paintings, such as the New Year's pictures sold by Sitong Firm, which is used as gold.

More important is its oxide, which is white in color and is called "tin white", which is an important additive for the production of porcelain, white emulsified glass, and white enamel filling.

The South China Sea air is highly corrosive, and in addition to the advanced process of baking blue, there is a simple treatment method.

When steel and bronze are soaked in molten tin for half an hour and then removed, the surface of the metal parts is coated with a layer of tin, which can also be used to make tin sheets for canning.

If it is made into an antimony-tin-copper alloy with "Lianshan tin", that is, antimony, tin, and copper alloy, which is used to wrap the bearing, it can reduce friction.

If it is alloyed with brass, the blowtorch can melt it, which is strong and corrosion-resistant, and is now widely used in the Cochin shipyard and the ordnance factory, which is today's welding rod.

There are two other things, lead word and tin foil, lead word not to mention, tin foil is fine in dry Shaanxi, and it can be said that it is inseparable from Jiaozhi for a moment.

Nowadays, the tin foil and tin skin used in Jiaozhi mainly come from Dali, and Xiao Gao Xiangye is very angry, because he makes all kinds of tableware, wine utensils, tea sets, ornaments, and stationery with tin, and the money he earns is much more than selling tin foil to Su You.

Before the Great Song Dynasty's annual tin output was only 330,000 catties, Su You went to the third division for inspection, and found that there was still some antimony, and even some zinc and lead were counted in it, and the real tin was less than 300,000 catties.

Su You threw the tin ingot with a smile: "How many?" ”

"100,000 catties."

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

Wang Shao was a little nervous: "There are several warehouses, and they are ...... The bottom of the mountain here seems to be ...... It's all about this. ”

"Mine one-" Su You was immediately excited: "Take me to see it!" ”

The storehouse was opened, and there were three whole storehouses, all of which were tin ingots.

The smelting of tin ore is very simple, using coke and quartz sand mixed into the furnace to fire, but the current traditional process needs to use lead bars at the discharge port to lead the metal tin from the furnace will flow out of the furnace continuously.

Moreover, the melting point of tin is very low, more than 200 degrees, and it is easy to be processed into metal blocks.

The purity of this batch of tin is extremely high, the color is white and bright, unlike the tin of the Great Song Dynasty, and it is necessary to use the method of the Shi family, inserting wood to remove iron, adjusting alum salt to detoxify, in fact, it is to remove arsenic, lead, sulfur to remove copper, etc., after a series of repeated smelting, in order to purify the black Song tin to pure tin as dazzling as silver.

The pewter made of this tin is now a very high-grade utensil, and its greatest use is to warm sake and tea boxes.

And the tin here doesn't seem to need to be rerefined at all.
