I'm using some of the fantastic carbon steel pans from de buyer. Mostly I've so fare are the mineral or mineral B ones. Now I've seen on some websites (amazon too in some cases) that they explicitly say that the "blue steel" ones are to be used "only" with induction. But on the website of de buyer they explicitly show that they could be used with burners too. Is this true? Any idea anyone why the blue induction should be used only on induction? I would guess the website of de buyer should be the reference in this case. I would appreciate any insight into this.
