"This is the beaker, this is the test tube, this is the stirring rod, this is the thermometer, the scale, the weights, the naphtha blowtorch"
A batch of experimental equipment was transferred from Huang Mingshan overnight, and Zhang Hao explained it to Zhou Xueyao. Zhou Xueyao was curious at first, but gradually became serious. She could see that these things were of great use.
Zhang Hao introduced it for a while, then smiled and said: "Come, let's start the experiment. Take 100 ml of ordinary water, low-level spiritual spring, intermediate spiritual spring, and high-level spiritual spring.
Grind the dragon blood stone and mix it evenly. Put 10 grams of powder into each beaker and stir gently and evenly"
Stir, continue to add, reheat
A whole new world slowly opened in front of Zhou Xueyao.
As for Zhang Hao, as the experiment progressed, he was also a little surprised: it seems that this dragon blood stone should be a 'mutated' saltpeter.
There were a few stone chips at the bottom of the beaker, but the solution in which the dragon's blood stone was dissolved showed a magnificent red color.
At the end of the experiment, Zhang Hao discovered that the high-grade spiritual spring dissolved the most saltpeter. When heated to 90 degrees, 100 ml of liquid actually dissolved more than 300 grams of dragon blood stone powder.
Then, the liquid was filtered, and then condensed and crystallized. More translucent blood-red crystals gradually precipitated under the beaker; the color of the solution also gradually became lighter.
"Look, it's purified." Zhang Hao pointed to the crystals at the bottom of the beaker and said to Zhou Xueyao with some pride.
"Let me try" Zhou Xueyao excitedly took the tools and got busy.
Zhang Hao sat next to him and looked at Zhou Xueyao, who was busy and serious; time passed little by little, and it was already a night before he knew it.
With the faint crowing of roosters coming from the distance, Zhou Xueyao had already refined the fifty kilograms brought by Zhang Hao into about 40 kilograms of pure crystals.
In one night, Zhou Xueyao has mastered the concept of dissolution curve and knows about precipitation and crystallization. Compared with traditional alchemy methods, the new chemical methods are unique and have demonstrated some advantages from the beginning:
? Simple, transparent and easier.
With the pure ¡®Dragon Blood Stone Powder¡¯, Zhang Hao rushed out of the courtyard excitedly, preparing to find some charcoal and sulfur. Unexpectedly, as soon as he came out, he saw a guard captain next to his father looking at him with strange eyes.
"Wei Qiang, what's going on?"
"Young Master, I asked you to go to the smelting base and tell me if it was successful."
"Ohok." Zhang Hao left after saying that.
Behind him, Wei Qiang was winking at his subordinates: "Young Master spent the night here, one night"
¡°We also left the lights on all night.¡± The guards began to comment enthusiastically.
¡¡¡¡
Zhang Hao quickly arrived at the smelting base and saw his father and Cheng Tao chatting and laughing, with Huang Mingshan and others beside them looking attentively listening.
"Xiaohao, come here." Zhang Shengde was very excited, "Thank you, Master Cheng. I found the solution in one night."
So fast? Zhang Hao was a little surprised, but he expressed his thanks first, and then looked at his father, Cheng Tao, Huang Mingshan and others with suspicion: Who can explain?
Huang Mingshan was still excited, so he immediately took Zhang Hao to check.
It turns out that the solution is too simple! According to the hidden meaning in Huang Ming's words: In fact, this method was not discovered by Cheng Tao at all, but proposed by Huang Mingshan and others:
This method was also used by the Zhang family when producing the 'new arrows', that is - molten coating.
Just dip the arrowhead in the melted black iron water.
But now it is just a matter of bathing the newly solidified steel embryo in ordinary black iron water, and covering the surface with a layer of ordinary black iron. In this way, the formation can be carved on the ordinary black iron layer.
This is equivalent to adding a soft shell to hard steel.
As for the method Zhang Hao proposed at the beginning, which is similar to "burning porcelain", it doesn't work. The flame is nothing, the Zhang family has oil; but after it is calcined again, it will destroy the properties of the steel, and heating at high temperatures will cause softening and deformation, condensation deformation, etc.
After hearing this, Zhang Hao asked Huang Mingshan in a low voice: "Then Cheng Tao has nothing to contribute?"
"No, there are quite a few. The thickness of the plating, and even the thickness, weight, format of weapons and armor, etc., were all determined or modified by Master Cheng. In addition, Master Cheng provided several simple but powerful methods. Formations. Including armor-breaking, defense, reinforcement and other very practical formations."
Zhang Hao nodded and looked at the freshly made steel armor, steel swords, etc. ?The weapons and armor modified by Cheng Tao have an indescribable charm, and seem to have murderous intent.
Zhang Hao suddenly realized that the past designs of Huang Mingshan and others were at best rigid industrial designs, but Cheng Tao's design probably had a little bit of art in it.
However, art is also a technology. We know that there is a word called - the art of killing!
And Cheng Tao integrated this 'art of killing' into weapons and armor.
The armor has spikes added to the elbows and ribs added to the arm guards - this increases the protective capability while ensuring a sufficiently low weight. The formation pattern just passes through the depression of the cold ribs. These ribs also ensure the safety of the formation pattern and increase the life of the weapons and armor.
The sword body has a waist-reducing design. This waist-reducing design makes the long sword even more cold.
The long knife is more slender, the thickness of the back of the knife is increased, and the blood groove is deepened, which greatly reduces the weight of the blade and increases the lethality of the knife.
Especially the soft black iron attached to the surface can greatly absorb impact and increase the strength of the sword. The layer of black iron covering it can also be used to carve formations. It can be said that it kills two birds with one stone.
Zhang Hao nodded with satisfaction, encouraged Huang Mingshan a few words, thanked Cheng Tao again, spoke to his father, took some charcoal, sulfur, and some ordinary saltpeter powder extracted before and left.
"Charcoal", Zhang Hao chose three types: charcoal, bamboo charcoal, and coke from petroleum smelting.
There is only one kind of sulfur for the time being, just ordinary sulfur; Zhang Hao has not yet found sulfur with 'spiritual material properties'.
When returning to Zhou Xueyao¡¯s courtyard, Zhou Xueyao was eating breakfast; there was an extra serving beside her. Seeing Zhang Hao coming back, he immediately lowered his head and looked red with embarrassment.
"What's going on?" She was so generous before, so why is she now a shy beauty?
¡°Looking at the suppressed smiles on the faces of the maids next to them, Zhang Hao was a little confused, but he didn¡¯t take it too seriously.
After having a hasty breakfast, Zhou Xueyao took the materials brought by Zhang Hao and began to mix different proportions of "gunpowder".
Zhang Hao vaguely remembers that the formula of ordinary black powder is: 7.5:1.5:1; in the previous test with ordinary saltpeter, this ratio is indeed the most powerful. But I wonder what will happen to the dragon blood stone?
It¡¯s just that Zhang Hao had this ratio when he opened his mouth, which made Zhou Xueyao very suspicious.
"We have done a lot of research before. But the power of ordinary black powder is really limited, so we haven't used it."
"Oh" Zhou Xueyao looked at Zhang Hao with suspicion for a while before starting to equip herself with brand new gunpowder. (Remember the website address: www.hlnovel.com
