I have the impression that mine is one that will work with an induction pad as well. First as the little bit of English on the little paper inside the kettle talked about it being able to be used with an electromagnetic plate which I figure is an induction pad. Secondly as I don't see a reason to put a special ring of white paint on the bottom if its meant for open flame or a non induction surface.
I have two, one cracked because I left it unattended on the induction plate :( but the chinese booklet does say they are safe for use on induction plate. I don't read Chinese but my mother does, and I have been using it for 5 months (second one).
One thing that I found out after my first one cracked was that these kettles need to be prepped before use ( the 2nd time I asked my mom to read out the info on booklet in detail) it said to boil rice porridge water (no rice solids, thick liquid only) for 1/2 hour. This would clean and also fill the pores which will extend the life of kettle according to Lin's ceramics.
My first one actually bled a lot even during boiling I had no idea where the moisture came from. I am speculating it was due to improper prepping or the lack of it. Having followed their advice the second time around no more moisture build up on the bottom i.e; the white ceramic magnetic conductive coating, and hissing noises.
Perhaps you already followed their prepping instructions, but speaking personally I find it benefits the kettle by following their advice.
The English instructions don't mention what is in the Chinese instructions which I find weird, I guess they assume the unfamiliarity with congee or rice porridge. It can make A REAL F*****G mess when you have never made congee it can boil over quite easily.
