As for the use of zinc metal produced from the Bakkens lead-zinc mine on the island of Newfoundland, Marlin actually had a plan for a long time.

The first use is naturally to use hot-dip galvanizing to make white iron sheets. For example, in order to prevent shelling, the city gate can be covered with a relatively thick white iron sheet, or white iron plate. In this way, the city gates' ability to resist shelling was greatly enhanced. And the white iron sheet is very good in corrosion resistance, and it is not afraid of wind and sun. Of course, the silver white iron sheet covered the city gate, and it looked quite entrenched. I don't know, I thought it was made of silver. But externally, Marin is definitely tinplated.

Of course, white iron sheets can also be used to wrap the waterline part of the wooden boat. Although the galvanized white iron sheet is not very good at seawater corrosion resistance, it is certainly much better than ordinary iron sheet. Although it can't catch up with the corrosion resistance of copper skin, it is cheaper. How expensive is copper now? Wrap the copper skin, then the cost of this boat will be scared to death. If you use galvanized white iron sheet, it's a big deal to change it every year, it's cheap anyway.

The second use is to mix zinc and copper to make cupronickel. What does it do...... Hehe, it's used to make fake silver coins......

The inferior silver coins, which are now popular in Europe with a mixture of silver and copper, look no different from white copper. Those inferior silver coins are forged with white copper, and ordinary people can't tell the real or fake at all. Marin plans to use white copper to imitate a large number of French silver coins, and then use fake silver coins to buy things from the French, and cheat the law......

As for the third use, it is also important. Marlin intends to use zinc to make zinc sulfate as a simple pesticide......

The characteristics of zinc sulfate are close to that of copper sulfate, which can replace the Bordeaux solution of copper sulfate and become a pesticide for the control of pests and diseases. Although the effect is not as good as those pesticides in later generations. However, there is no problem in dealing with general pests and diseases. At the very least, it's much better than not using pesticides.

Moreover, the production cost of zinc is lower than that of copper (mainly the copper content of copper ore is very low, mostly about 1%, and the content of zinc is much higher), and the cost of using zinc to produce copper sulfate, as a pesticide, is lower than that of copper sulfate.

On the island of Gran Inagua, east of the island of Cuba, large amounts of sulfuric acid and sulfurous acid by-products are produced when laterite nickel ore (nickel sulfide) is processed. It just so happens that excess zinc from Newfoundland can be reacted with sulfuric acid, a by-product of the treatment of Moa laterite nickel ore, to produce a large amount of zinc sulfate, which is used as the most advanced pesticide.

The effectiveness of this pesticide may be ordinary, but it also has the benefit of low toxicity. Moreover, zinc sulfate can also add some nutrients to fruit trees or crops, which is a kind of auxiliary fertilizer. Crucially, because Marlin also has a large number of cheap sulfuric acid by-products, the cost of producing zinc sulfate is very low and can be produced in large quantities. Moreover, there is no fear that others will copy it. Because, other countries don't know what zinc is.

……

Thinking that with zinc, Marin could use zinc to make a large number of corrosion-resistant white iron sheets, and coat the plate armor with silver, and then the cavalry under his command pulled the scene, Marin smiled.

This reminded Marin of a very popular organization when he played Warcraft in his previous life, the Knights of the Silver Hand. The members of this order went out, and all of them were extremely popular. Why? Because the armor they wore was either gold or silver, and they looked like great tyrants.

The plate armor coated with molten zinc must also be white and shining, like silver. Such a group of knights came out, not to mention combat effectiveness, just the sunlight reflected by the galvanized layer could blind the opponent's dog eyes. Moreover, with the galvanized layer, the plate armor is not easy to rust, and the loading ratio and practicality are correct.

Speaking of this zinc sulfate pesticide, in addition to being easy to do, it also has the characteristics of strong confidentiality. If you use the original Bordeaux solution, the blue characteristics of copper sulfate solution can easily make chemists from other countries succeed. I use zinc sulfate, white powder, like salt, before there is no modern method of testing, there is a kind of you go to the cottage......

As for the manufacture of counterfeit silver coins from cupronickel, it goes without saying. France is rich, isn't it? Well, I used white copper to make a large number of counterfeit silver coins without silver, and went to rob the wealth of France and buy French goods. What kind of oak for shipbuilding (The French seem to like to use oak to make barrels and make high-end wines, while the British prefer to use oak for shipbuilding.) So, France has always been a landlubber, and England has become the hegemon of the sea), cattle and horses, and iron and copper......

Anyway, with counterfeit silver coins, a large number of important strategic materials were purchased, so that the French suffered losses. Although the cost of copper is not low, because the production cost of zinc is much lower than that of copper, the cost of copper is lower than that of pure copper coins, and naturally it is much lower than the cost of inferior coins of copper-silver alloys made in France. At least, the inferior silver coins in France still contain silver, and the fake silver coins made by Marin do not contain silver at all, and the cost is still low...... Coupled with the use of spiral minting machines, counterfeit silver coins can be produced faster and more efficiently, and the manufacturing cost is naturally lower. The only concern is that the counterfeit silver coin produced with the spiral coin may be too fine to look more beautiful than the original inferior French silver coin, and more like a real silver coin...... It would be ridiculous if it aroused suspicion because of this...... Of course, with the current level of the French, it is difficult to find out the problem even if they are suspicious......

When the time comes, a large number of counterfeit silver coins without silver will flood the French market, which will surely make a lot of money from the French and deal a blow to the French economy.

While Marin was sinisterly calculating the French, on the island of Ireland, Edward of the House of York was busy appealing to the Holy See.

Before, after receiving Marin's letter, he was pleasantly surprised to see that Marin generously admitted that he was the person behind the Beihai Chamber of Commerce in the letter. Such a powerful figure, who was on this side from the beginning, although this person loved land and mineral deposits, was not unacceptable.

The most important thing is that without strong foreign aid, Edward would not have the confidence to defeat Henry VII, not at all.

He was not a fool and knew that France and Scotland supported him in order to make England in chaos, and not to really be friendly with him.

But Marin is different, this powerful German military aristocracy, has no contradictions with England, and will not be hostile to the strength of England. Moreover, this guy is not a monarch, just a prince and nobleman.

Such a person, even if he is given a fief or two of counties, it is nothing. Because, you will get more.

Moreover, his sister Margaret's suggestion to Edward was very good - arranging Marin's fief on the northern border could allow Marin to help guard the northern border, and at the same time, he could use the Scottish soldiers and horses to contain Marin's army in the fiefdom.

And Marin's advice to Edward in the letter also intrigued Edward. Why? If he can get the support of the Holy See, he will be the rightful king of England, and there will be a large number of supporters who will choose to support him. Unlike now, there is basically no one to support him, making it difficult for him to compete with Henry VII.

So, Edward of the House of York immediately took action. Of course, he did not immediately send people to Rome to complain, but first sent envoys to France and Scotland to ask them to help prove that he was indeed Edward of the House of York and prove his legal identity. Then, he sent someone to the Holy See to complain, accusing Henry VII of sending troops to kill the king, and asking the Holy See to declare that Henry VII was the murderer of the king, and he was the legitimate heir to the throne of England......

The French and Scottish sides seem to be very interested in the idea of Edward's appeal. Knowing that Edward's envoy would go to Rome to complain, the French and Scottish sides not only sent people to accompany Edward to Rome to help prove his identity, but also strongly supported Edward's appeal.

As long as the appeal is successful, then King Henry VII of England will become the villain's killer. Then, Edward's identity can instantly become the rightful heir to the throne, and will have more and more supporters. Then, there will be an even better chance of defeating Henry VII......

It's been modified, and it's finally time to go to sleep......
