Not necessarily. The label "microwave and dishwasher safe" on a bowl indicates that it is specifically designed to be used in a microwave oven and washed in a dishwasher without any adverse effects. However, it does not automatically imply that the bowl is safe for use in a conventional oven.
To determine if a bowl is safe for use in an oven, you should check for specific information on the bowl itself or its packaging. Look for indications such as "oven-safe" or temperature limits provided by the manufacturer. Some bowls may be labeled as "oven-safe up to a certain temperature," indicating the maximum temperature the bowl can withstand without the risk of damage.
If you cannot find any explicit information about the bowl's suitability for oven use, it is best to assume that it is not oven-safe and avoid using it in the oven to prevent any potential damage or accidents.
