Cast-iron skillets, pots, and pans are made all in one piece when manufactured. They are made from molten iron that is then poured into casts.
Dutch ovens are made the same way all in one piece. The pot has handles molded in one piece with the oven used for moving them safely during the cooking process. They have fitted lids that are heavy and tight to keep the steam inside the pot. The lid loop is also in one piece molded along with the lid.
