It is well known that casserole can be used in the oven safely. However, people are not sure about glass containers. Is it safe to take out frozen food in a glass container and directly heat it up in the oven? Are all kinds of glass safe to be used in the oven? Is there any limit of temperature that the glass can endure? The short answer is, yes, you can place the glass container in the oven and warm it up with the food.
However, not all types of glass can be heated. In this blog, Sparkling and Beyond will elaborate on the specific usage of glass containers in ovens and some precautions you should keep in mind.
When sending glass to oven, avoid rapid change of temperatures
Glass kitchen wares could break into pieces when the temperatures rise or drop swiftly. It is advised that the glassware you are about to put into the preheated oven should be at room temperature.
If a frozen glass container is sent straight to the oven, the glass could break in the heating process. Similarly, after heating, the glass plate should be put on a warm or room-temperature table instead of a cold one.
Tempered glass is suitable for heating in the oven
Tempered glass is the type that can be warmed up in the oven. If you are not certain, there is usually a label on each glassware showing if this ware is oven safe.
Glass for alcohol, small glass bowls and lid mostly cannot endure the high temperature in the oven unless they are labelled otherwise.
Be careful of the heating temperature when setting the oven
Although some glass can be used in the oven, make sure the heating temperature does not pass the limit, which can be found on the glass itself.
Such limits can range from 350 °F to 500 °F so make sure you are aware of this restriction.
Check weak spots on your glassware before putting glass in the oven
It is important to make sure your glass cookers do not contain any break or scrape as these cracks could become the breaking points when the cookers experience fluctuated temperature.
Pour some water in the glass pan bottom when heating dried food
When warming up dried food in a glass pan, it is recommended to pour some water on the pan bottom.
When the food is cooked, it is likely to leak out some liquid, which will flow down and stay on the pan.
As this liquid could be colder, when it meets the hot surface of the pan, the glass could crack.
Therefore, it is important to retain some water on the bottom so that the released liquid could be heated when it meets the bottom.
Many people are hesitant to heat their food in the oven with glassware. It should be noted that as long as the glass is tempered or marked to be oven safe, you can use them safely within their specific temperature limit.
Moreover, make sure not to let the glass expose to drastic changes of temperature and check whether the glass surface is scratch free.
Finally, tip some water in the glass container when heating your food up to avoid the glassware from breaking abruptly.
