Why Nanbu tetsubin becomes stronger against rust as we use it?

Nambu tetsubin of Roji is done a special finishing “Kama-yaki” or in another word “Kanake-dome.”

In this “Kama-yaki” finishing, put Nanbu tetsubin into charcoal fire around 800~1000℃. The tetsubin is burned until it gets bright red. This process makes oxide film on the surface of Nanbu tetsubin.
