In general, glass bowls can be safe to use in the oven, but it depends on the specific type of glass and its manufacturer's instructions. Some glass bowls are designed and labeled as oven-safe, while others are not.
To determine if a glass bowl is safe for oven use, you should check the label or packaging it came with. Look for information regarding its maximum recommended temperature and if it is approved for oven use. If the bowl is labeled as oven-safe, you can generally use it for baking or heating food in the oven.
It's important to note that sudden temperature changes can cause glass to break, so you should avoid placing a cold glass bowl directly into a hot oven or vice versa. Preheating the oven with the glass bowl inside can help minimize this risk. Additionally, avoid subjecting the glass bowl to extreme temperature variations, such as placing it directly from the oven onto a cold surface or exposing it to a direct flame.
If you are uncertain about the oven safety of a specific glass bowl, it's best to refer to the manufacturer's instructions or contact the manufacturer for clarification.
