Not necessarily. While "microwave safe" indicates that a bowl is designed to be used in the microwave without causing any damage or releasing harmful chemicals, it doesn't automatically mean that the bowl is heatproof for stovetop use.
Microwave-safe materials are usually designed to withstand the heat generated by microwave ovens, which is primarily caused by the excitation of water molecules in the food. However, stovetop cooking involves direct exposure to flames or intense heat, which can exceed the temperatures encountered in a microwave.
To be heatproof for stovetop use, a bowl needs to be made from materials that can withstand higher temperatures, such as certain types of glass, stainless steel, or certain heat-resistant ceramics (e.g., oven-safe ceramic cookware). These materials are explicitly labeled as "heatproof" or "stovetop safe" in the product description or packaging.
To be safe, always check the manufacturer's instructions or packaging to determine if a bowl is heatproof for stovetop use. Using a bowl that is not designed for stovetop cooking can lead to breakage, release of harmful chemicals, or other safety hazards. If you're unsure about a particular bowl's suitability for stovetop use, it's best to avoid using it on the stove and look for an alternative heatproof container.
