The cast iron tea kettle I got from the dealer is a piece of crap. From the very first day I used it, it got all rusty and nasty on the inside. I scrubbed and seasoned several times and it keeps getting gross. I have a problem with evaporating dark brown water 24-7 into the air my two year old and new born breathe. For now I am keeping a regular kitchen pot on a trivet on the stove. My stovetop only gets to around 500 or so, but I am leary about putting nonstick cookware directly on the stove. Ideally, I want something black, but I am also considering stainless steel or brass. Any other suggestions? What is good? What can be put directly on the stove without worry of damage or rusty water?
