non-rusting sauce pot for boiling water I am trying to find a way to boil 1-2 quarts of water for 10 minutes and want to be absolutely sure that the pot doesn't leak any chemicals into the water. I have tried 3 stainless steel sauce pots but they all rusted (and one rusted after a single use). What kind of sauce pot can I get that is guaranteed not to rust or break due to temperature and not leak any chemicals into the water? Price is less important than finding the right item (I'm only going to buy 1).
Just use a glass pot, Corningware make some decent ones that can be used on a stove. But any glass pot designed to work on a stove with direct heat/flame exposure should work in this case.

If you are worried about uneven heating or hot spots on a gas range due to less conductive glass, you can use a cast iron or aluminum heat diffuser plate under the glass to even out the heat.
