I think that's the point I tried to make though not very well. They work by inducing a current in ferrous pans not by radiant heating but my recollection was that they'll also heat ferrous objects in the near vicinity, eg a metal surface underneath them.I don't think that's how they work (could be wrong). My understanding is that the glass surface doesn't get hot but the cooking utensil (saucepan/fry-pan/kettle) does
