Not all materials are suitable for use in a microwave oven. Here are some materials that can be safely used in a microwave:
Glass: Glass dishes and containers are generally safe to use in a microwave, as long as they are not cracked or chipped.
Ceramic: Most ceramic dishes and containers are safe to use in a microwave, but you should check with the manufacturer to be sure.
Paper: Plain white paper towels, paper plates, and napkins can be used in a microwave, but paper with designs or prints may contain metallic ink that can spark and cause a fire.
Plastic: Only microwave-safe plastic containers should be used in a microwave. Look for the microwave-safe symbol on the bottom of the container. Avoid using plastic containers that are cracked, warped, or discolored.
Silicone: Silicone baking mats and molds are safe to use in a microwave.
Wood: Wood utensils and cutting boards should not be used in a microwave, as they can dry out and crack, and may even catch fire.
Metal: Metal should never be used in a microwave, as it can cause sparks and potentially start a fire.
Always check the manufacturer's instructions before using any material in a microwave oven, and use caution when handling hot items
