Which brand was it that warped? So we know to avoid them.
Do you have a link to a source with more info on the needed minimum thickness of the outer magnetic layer? I imagine there's a point of diminishing return, and I'd love to see some research showing the efficacy of various thicknesses of this outer magnetic layer.
New rivets can be made with a rivet gun forever. You can also re-weld, but it's harder (and you're more likely to damage the pot if you don't do a good job welding it).
I guess I should have mentioned that this is for a community house whose kitchen will be shared with others.
I'm afraid one of my younger housemates will break the induction glass cooktop with cast iron. And I certainly can't expect them to take care of the seasonings on the pans. That's why I was thinking (3-ply) stainless steel. It's more, err, forgiving
Yikes. Yeah, warping on the bottom is a big no-go for induction. The heating loss is pretty exponential the further it is from the ceramic glass top above the coils.
