When using the preheat function in a microwave oven that combines convection and grill modes, it's essential to use utensils that are microwave-safe and suitable for high temperatures, such as 250 degrees Celsius (482 degrees Fahrenheit). Here are some materials that are generally safe to use in such modes:
Microwave-Safe Glass: Heat-resistant glass cookware, such as Pyrex or borosilicate glass, is safe for use in microwave ovens and can withstand higher temperatures. They are suitable for convection and grill modes.
Ceramic and Stoneware: Certain types of ceramic and stoneware dishes are labeled as microwave-safe and can handle high temperatures. However, always check the manufacturer's guidelines to ensure they are suitable for convection and grill modes.
Silicone: High-quality, microwave-safe silicone utensils can be used in convection and grill modes. Silicone is heat-resistant and can handle temperatures up to 250 degrees Celsius.
Oven-Safe Metal: Some microwave-safe metal cookware may be suitable for use in the combination modes, but you need to ensure they are specifically labeled as "microwave-safe" and are designed for use in a microwave oven. Some microwave-safe metal utensils can withstand the grill mode but might not be safe for convection mode.
Remember to avoid using utensils made from materials that are not microwave-safe or not suitable for high temperatures, such as regular metal cookware, plastic containers without microwave-safe labels, and utensils with metallic accents or coatings. Using improper materials in the microwave can lead to potential hazards, damage to the microwave, or even cause fires.
Always check the manufacturer's instructions and any labels on your utensils to ensure they are safe for use in the specific modes and temperatures of your microwave oven. When in doubt, it's best to use microwave-safe glass or ceramic cookware, as they are generally compatible with a wider range of cooking methods.
