Plates are flat, circular or oval-shaped dishes used for serving food. They are commonly made of ceramic, porcelain, glass, or plastic. Plates come in various sizes, shapes, and styles, ranging from traditional round plates to square or rectangular plates, and can have decorative patterns or solid colors. Some plates may have a lip or raised edge to keep food from sliding off, while others may have compartments or dividers to separate different food items. Plates may also be microwave and dishwasher safe for easy heating and cleaning.
