It depends on the material your plate is made of. For example, you can never put a plastic plate in the oven or under the grill. Likewise, this is the case for more of the glass tableware, whereas some of the high-quality ceramic and bone china accessories are grill safe. If not, the plates will crack when they get in contact with any level of thermal stress. So, if you are looking for grill friendly options, read the product description section of selected products and make buying decisions accordingly.
