Simple way to tell if it will work, place a magnet against the stainless and see if it is magnetic, if it is, induction cooking should work, induction cooking works with a magnetic field so it requires an amount of iron in the pan! We have some pans that I thought would have worked and didn't and others I thought are aluminium but they must have iron in the base as they work! Hope this helps.

Thank you Ken. The weird thing is that that magnet did not actually stick, even though the on-line company said that it would, yet the pot worked anyhow. I bought this item on-line, and even though they claimed it would work on 'all' induction cookers, there was one review which said that it hadn't worked. On the Ecoheat it worked, so I am happy.
