I bought a Wolf induction cook top and so I went out and bought a top of the line cookware set - All-Clad's Copper Core 10-Piece set.  All-Clad stated that t set was "Compatible with all cooktops, including induction" but I soon learned that they were not compatible.  The combination of copper and stainless steel overheated the cooktops "burners" and result in the stove to shut-down one of the burneers to prevent over-heating and damage to the cooktop.  The technical service representative at Wolf said not to use pots and pans with different layers of metal.  So, here I am with a very expensive 10-piece set cookware set that I cannot use on my induction cooktop.
