Iron is a grey metal. I read that when you cook it turns black from a reaction to the food. But this has never been used.

I tagged utensils but technically this is not a utensil or is it.

    Actually the "equipment" tag might be better (which I added and is awaiting approval). I don't know the answer as to why, but every single one of the cast iron skillets I have seen are indeed black Aug 12, 2023 at 21:13

Unseasoned cast iron is gray, until it rusts. But it’s common for manufacturers to factory-season cast iron, which makes it black. The black color comes from carbonised oil.

  • Note that manufacturers specifically season their cast iron black by adding carbon, because that's what people are used to from antique cast iron.
