I say that cast iron cookware has had resurgence in use and popularity, not because people ever actually stopped using it, but because we are using it more than ever before. Cast iron cookware is available in a vast variety of item types: camping cookware, tea kettles/tea pots, Dutch ovens, trivets, fry pans, crocks, round French ovens, grills, griddles, skillets with cast iron flat iron flat presses, fondue sets, deep dish lasagna bakers, pizza pans, round griddles, covered casseroles, gingerbread house molds, corn bread pans, Moroccan tangines, and the list goes on.
One item that has intrigued me recently is the cast iron tea kettle. There are different types and brands of tea kettles from different from countries; besides American made tea kettles, Japanese kettles and Old Dutch kettles seem to be the most readily available. I noticed that the Japanese cast iron tea kettles are made in different weights of cast iron; I have seen them in 10 oz., 24 oz., 32 oz. and 45 oz. weights. The Old Dutch tea kettles I have seen are similar in weights to the Japanese kettles. These tea kettle weights in ounces of cast iron are 28 oz., 34 oz., 38 oz. and 48 oz. Because these tea kettles are the heaviest (and thickest) of the tea kettles made (in comparison to glass tea kettles, stainless tea kettles & copper tea kettles) its good to know they can be found in various sizes and weights. It should be easy to find something you prefer in both style and weight.
