製刀者可以藉由溫度(相州傳800 o C vs 備前傳780 o C)和含碳量的控制,在焠火時製造出沸(にえ,Nie)與匂(におい,Nioi)的效果。 沸 contains bigger white sand like grains that are visible to the naked eye & 匂 contains smaller grains that are invisible to the naked eye . 沸 can be created by higher temperature (800 o C) or higher carbon content & 匂 can be created by lower temperature (800 o C) or lower carbon content . 早期中國山西出產的折疊鍛鐵因為含碳量低,不但刀刃硬度不夠,也要藉助於化學反應來模仿沸與匂,但是這幾年含碳量顯然有改善,刀刃硬度似乎已符合需要,就連沸與匂也不會擦擦就沒了。 |
