Cast iron tea kettles are known for keeping water hot and for their traditional look. Japanese tetsubin kettles are often used to boil water, while enameled interiors help prevent rust. Not all of these suit direct stove heat, so read the maker’s guidance carefully.
The six kettles below range from Japanese-style tetsubin to enameled kettles. Many cast iron teapots look like kettles but are meant only for steeping, not for boiling over a flame. If you want to boil water on a stove, look for a kettle the maker says is made for it. If you mainly want to keep tea warm at the table, a steeping-only pot is a safer match. Ask what you plan to do before you decide. Also check the capacity, since many tetsubin hold less than a standard stovetop kettle, and keep the handle clear of the flame.
