OK. #2. Someone mentioned plastic kettles and I couldn't figure out how you could put them on the burner and not melt but I think now I understand that they are the ones that have a heating element inside. Still wonder, if that is the case, why the hot water doesn't melt the plastic??? Possible answer, a heat resistant plastic.
The plastic won't melt until much higher temperatures than boiling water are reached, but it often
does impart a taste to the water until the kettle has been used a good few dozen times, if not more. In fact the taste never really seems to go away with some of them. The manufacturers normally suggest one or two runs with the kettle filled to maximum and the boiling water discarded before use to clear the films left on the interior of the plastic and the element during manufacture, but that's normally nowhere near enough.
Most of the plastic jug kettles have elements which are molded in place during manufacture and non-replaceable, so once the element burns out, the whole kettle is useless.
They're not a patch on the old Russell Hobbs stainless steel kettles that you no doubt remember Jim.
