Thousand-year-old cold iron is extremely rare and extremely precious, and this kind of cold iron is only produced in extremely cold places, and it is extremely cold in itself. If you want to melt it, you need to cast it at an extremely high temperature, and for the temperature The control of the iron requires extreme precision, and if there is a slight deviation, the coldness of the cold iron will be burned.
"The blade of this Remnant Ice Sword is light and thin. Now it is a problem to cool it and shape it. If it is directly placed in ice water to cool it quickly, the alternation of cold and heat is too rapid, and it may break. If it is cooled slowly, the I'm afraid the thin blade will lose its shape during cooling." The person in charge also had a headache, the Remnant Ice Sword had been forged long ago, but because the blade was too thin, I couldn't find a way to cool it down. , dragged on for a few days, if it dragged on, the characteristics of the cold iron might be damaged.
Moreover, the sword body is too thin, and it is very difficult to forge it once. Even the blacksmiths in the same batch cannot guarantee that they can forge the same sword.
"Ye girl, if it's up to you, what is the best way to cool this Remnant Ice Sword?" The person in charge suddenly asked Ye Qingtang.
Ye Qingtang did not respond immediately.
The in-charge's inquiry caught the attention of the several swordsmiths who were arguing, and they subconsciously turned their heads to look at the object of the in-charge's inquiry.
I thought that the one who could ask the person in charge to ask for an opinion must be an incredible senior forging, but I didn't want to...
What they saw was a film of a fifteen or sixteen-year-old girl.
Immediately, the expressions of those blacksmiths dropped.
How much forging skills does such a yellow-haired girl know
However, they only thought they were in charge and asked later, without any hope, they turned their heads and continued the discussion.
Ye Qingtang looked at the Bingbing sword for a while, hesitated for a moment before slowly saying: "Ice water is easy to break, but warm water is easy to change. If you use frost to condense the water, maybe it can be done."
"Shuang Ningshui?" The person in charge was slightly taken aback.
In essence, Frost Condensed Water is not water, but more like a thick liquid. This liquid is very viscous, has a certain degree of toughness, and has a very low temperature and extremely high heat resistance.
Frost condensation water is generally used by them for wide-filling boxing gloves. Because it will not be evaporated, it can be temporarily used as a filler under high temperature to set the shape.
But…
He has never heard of frost condensing water to cool weapons.
The person in charge fell into hesitation.
Ye Qingtang's words caught the attention of those 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 could the Frost Ningshui be used for cooling? What are you kidding?" A blacksmith said displeased.
Although the frost water will not be evaporated, but because of its strong thermal conductivity, it will be quickly transferred to a high temperature by high-temperature objects, and there is no way to maintain a temperature sufficient to cool the weapon.
Those few blacksmiths only thought that this girl was a brat who didn't know the way, and the opinions she raised were like jokes.
Ye Qingtang shrugged her shoulders and didn't argue. Anyway, the Remnant Ice Sword didn't belong to her, so she was just answering the words in charge.
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 then went all out and said, "Ye girl, if you do this, you can be sure of it." ?”
