But I did read somewhere that stainless steel gives off nickel.
I often wonder if there is length of time, or degree of temperature, or even a type of food, qualification to this characteristic, in my own stainless steel pots...if it is even true.
There was once a discussion (in this same Ask CureZone forum, I believe), on the various materials used for pots.
Maybe someone will come forward with the URL, in time to be useful to you.
