After 15 years, my tea kettle needs to be replaced. The bottom is all corroded, and when I wash it out, bits of black stuff come out.
I looked over all kinds of teapots...didn't mind spending a few $$, as I'm a big iced tea drinker. But after checking out Kitchen Aide, Le Creuset, and several other pricey ones, I ended up buying a Revere Ware tea kettle that is stainless steel with a copper bottom. It's guaranteed for 25 years, so it will probably outlast me.
And it was only about $30, including shipping.
My blue speckled tea pitcher has also gotten pretty worn...can't get it clean in the bottom anymore, so I also ordered a stainless steel pitcher from Polar for about the same price as the teapot.
I sure hope my tea starts tasting better...lately, it's been pretty nasty.
