Ovenware is pots, dishes and trays made so you can put them in a hot oven and they will not crack, melt or burst. Ordinary plastic would warp; some thin glass not made for the oven can shatter when the heat hits it. Ovenware is built for that job — often thick glass, ceramic, stoneware or a metal that can take the heat. Shops sell it as single pieces or as a set. Bakeware is a close cousin: that word leans toward tins and trays for cakes and biscuits, while ovenware is the wider, quieter word for anything that may go in the oven and come out whole. It is a practical kitchen word, not a fancy one. You do not call the oven itself ovenware — only the things you put inside it.
