Some pans will warp at the same heat CI can easily take. This is especially
true of cheap, thin pans. Tri-;ply pans are made of different metals. At
very high heat they will expand at slightly different rates. This can cause
delamination.

Most any pan with a liquid in it cannot be overheated. CI, OTOH, can be
preheated to very high temperature when dry. Good for steaks and blackened
foods.
