It depends on the type of plate you have. Most plates that are labeled as oven-safe can be used in the oven. These plates are usually made of materials such as tempered glass, ceramic, or certain types of stoneware. However, it's essential to check the manufacturer's instructions or any labels on the plate to determine if it is oven-safe and up to what temperature.
If your plate is not specifically labeled as oven-safe, it's best to err on the side of caution and avoid putting it in the oven. Plates made of materials like regular glass or certain types of plastic can break or warp when exposed to high heat, which can be dangerous and cause damage to your oven.
To be sure, always consult the manufacturer's guidelines or packaging for information about the oven safety of your specific plate.
