we got a teapot that we wanted to use on induction cooktop. it failed the magnet test - magnet does not stick anywhere on it. however, the manufacturer (bredemeijer) on their website says that all their cookware is induction compatible. so i thought this is an old/discontinued model or something. before returning it i decided to just give it a try on our bosch cooktop - the cooktop did not report an error like it usually does with incompatible cookware and heated the bottom of the teapot! so i guess it's a keeper but does raise a question of the validity of magnet test. there must be some physics-heavy explanation to this paradox. the teapot is shiny and made of very thin metal, said to be SS. google bredemeijer ceylon teapot if interested.it is made in Holland.
