Millennium cold iron is extremely rare and extremely precious, and this kind of cold iron is only produced in extremely cold places, and it has a very high degree of coldness. The control of the iron requires extreme precision, and a slight deviation will cause the coldness of the cold iron to be burned.
"This remnant ice sword has a thin and light body. Now I want to cool it to shape, but it has become a problem. If it is directly placed in ice water to cool quickly, the alternating hot and cold is too fast, and I am afraid it will break. If it is cooled slowly, this The thin and light blade might lose its shape during the cooling process.” The person in charge also had a headache, this Can Bing Sword had already been forged, but because the blade was too thin, there was no time to find a cooling method. , dragged on for a few days, if it was dragged on, the characteristics of cold iron would be damaged.
Moreover, the body of this sword is too thin, and it is very difficult to forge it just once. Even the blacksmiths of the same batch cannot guarantee that they can make the same sword.
"Girl Ye, if it's up to you, which method is the best way to cool this Bingbing Sword?" the person in charge suddenly asked Ye Qingtang.
Ye Qingtang did not respond immediately.
The inquiries of the master caught the attention of the swordsmiths in dispute, and they turned their heads subconsciously to look at the object of the master's inquiry.
I thought that the person in charge of asking for opinions must be a great forging senior, but I didn't want to...
What they saw turned out to be a movie of a little girl of fifteen or sixteen years old.
Immediately, the faces of those blacksmiths were pulled down.
How much forging skills can such a yellow-haired girl know?
However, they only regarded it as the person in charge and then asked, without any hope, they turned their heads and continued the discussion.
Ye Qingtang looked at the remnant ice sword for a while, then hesitated for a moment before slowly saying: "Ice water is easy to break, and warm water is easy to change. If you use frost to condense water, it may be possible."
"Shuang Ningshui?" The person in charge was slightly taken aback.
In essence, frost condensate is not water, but more like a thick liquid. This liquid is very sticky, has a certain toughness, and has a very low temperature and extremely high heat resistance.
Frost condensate is generally used for wide-filling gloves. Because it will not be evaporated, it can be temporarily used as a filler under high temperature.
But……
He had never heard of frost condensate to cool weapons.
The person in charge fell into hesitation.
Ye Qingtang's words caught the attention of the blacksmiths, and they all looked at Ye Qingtang with disapproval written in their eyes.
"Little girl, don't talk nonsense if you don't understand, how can frost condensate be used for cooling? What are you kidding." A blacksmith said displeased.
Although the frost water will not be evaporated, because of its strong thermal conductivity, it will soon be transmitted to a high temperature by high-temperature objects, and there is no way to maintain the temperature enough to cool the blade.
Those blacksmiths only thought that this girl was a little devil who didn't understand the way, and their opinions were like a joke.
Ye Qingtang shrugged and didn't argue anything. Anyway, the Can Bingjian didn't belong to her, she just answered the commander's words.
The Can Bingjian had to be cooled today, and everyone couldn't think of a suitable method. The person in charge looked at Ye Qingtang thoughtfully, and immediately went out: "Ye girl, if you do this, you can be quite sure. ?"
