@Goldenzeal It's about "King's Iron" and a "Forge" instead of a "Loaf" and an "Oven" but yeah.
I can't think of any more "reincarnated as object" manga but there's Mynoghra where he reincarnates as a vaguely humanoid blob of darkness.
Tangentially, there's this one.
@moel But did you realize that Lusty Argonian Maid is a near-word-for-word exchange from Stephen King's Eyes of the Dragon?
@Goldenzeal I also didn't see the one where the guy gets reincarnated as a hot spring up there.
