Weapon Smithing (2)

"Lower the temperature required for quenching?" Luo Qiqi was taken aback.

Weren't weapons quenched with water? There was a limit to how cold a water could be before it would turn into ice, so how could the temperature required for quenching be reduced?

Besides, Zhang Xuan was viewing the matter too lightly. The difference in the temperature wasn't all that mattered. More importantly, quenching had to be done within the durability limit of the weapon. Otherwise, the weapon might be unable to endure the abrupt change in temperature and shatter!

There were many blacksmiths who had tried to change the substance used for quenching so as to further raise the tier of their crafted weapon, but more often than not, the quenching fluid ended up reacting with their weapon instead. As a result, the weapon they had forged with great difficulty shattered, resulting in a waste of their effort and precious ores.
