Whether baking or roasting in an oven, the dish and bakeware determines the flavor and texture of the food. Glass cookware has numerous benefits when cooking in the oven including non-toxic, easy to clean, convenient to store and reheat, visibility, and serving large quantities for a crowd.
However, not all glass containers is heat resistant and works for oven cooking. Some may break or cracked due to high heat, therefore understanding the type of cookware for use in an oven is important.
Can you put glass in oven? Yes, you can put glass bakeware in an oven when it is not labeled as oven-safe. However, non-tempered glass is not capable to handle oven heat.
If the glass is oven-safe, examine for any cracks or scratches that may result in breakage.
Furthermore, glass oven containers that have been stored in fridge or freezer must come to room temperature prior to cook or reheat in the oven to avoid extreme temperature changes. Rapid change in temperature will cause the dish to expand and shatter instantly.
Glass dishes are one of the dish to cook in the oven for pasta, casserole, and baked goods. They make it easy to serve, has good visibility to check the doneness, and simply throw in the dishwasher to clean up the mess.
But there is high chance of shattering the dish when not in caution. This article discuss what are some tips and precaution to take to cook with glass dishes in the oven.
Will a glass dish break in the oven?
Yes, a glass dish may break in the oven due to thermal shock resulting from extreme temperature changes.
Typically, glass in not able to handle the rapid temperature fluctuations compared to any other material types.
For instance, transferring the refrigerated glass container directly to preheated oven, the quick temperature changes can cause the glass break.
To avoid a glass dish break in the oven, consider to let it come down to room temperature. Ensure the glassware is oven-safe and avoid heating the glass dish heat below 302 degrees Fahrenheit or 150 degrees Celsius.
What temperature does glass break in the oven?
In general, untempered glass begins to crack and breaks at 302 to 392 degrees Fahrenheit or 150 to 200 degrees Celsius. However, tempered glass indicates various breaking point.
- Crystal: 150 to 200 degrees Fahrenheit or 65 to 93 degrees Celsius
- Pyrex: 425 degrees Fahrenheit or 218 degrees Celsius
- Tempered glass: 470 degrees Fahrenheit or 243 degrees Celsius
Not only checking the oven-safe symbol at the bottom of the dish but also look for materials that the dish is made out of to understand the maximum temperature point to avoid from shattering.
Will cold glass shatter in oven?
Yes, cold glass will shatter in the oven. In fact, it is recommended to never place a cold glass in a hot oven due to extreme temperature differences that cause the glass to shatter.
Some of the oven-safe glass may be placed in cold glass, but follow precautions and manufacturer’s instruction to be sure that it is heat-resistant.
To prevent the cold glass from shattering in the oven, avoid drastic temperature change but letting it to come down to room temperature, use tempered glass, look for cracks, and follow the direction to cook or reheat properly.
Can glass go in the oven at 400?
It depends on if the glassware is tempered or oven safe. Certain glass can go in the oven at 400 degrees Fahrenheit, however not all glassware can withstand the high heat.
The type of glass that has the highest heat resistant is the Pyrex glass. It can be used in oven temperature up to 425 degrees Fahrenheit or 218 degrees Celsius.
The Pyrex glass is made out of Borosilicate which can easily handle extreme heat. But avoid broiler mode in the oven where contacting with heat can cause the Pyrex to shatter or break.
When in doubt, always check your glassware for the recommended heat range in the manufacturer’s instruction manual.
Glass in Oven: Conclusion
Not all glass is oven-safe, especially kinds that are not tempered with no indication of oven-safe symbol. Little scratches or cracks can shatter or break in the glass more easily when coming in contact with sudden temperature changes.
Thermal shock is something you need to avoid when cooking or reheating food in a glassware in the oven. Typically oven-safe glass dishes have maximum temperature to handle, so refer to manufacturer’s guide for explicit recommendations.
Untempered glass has a maximum heat range of 320 to 392 degrees Fahrenheit or 150 to 200 degrees Celsius to prevent from breaking. Crystal, Pyrex, and tempered glass have different temperature points to be aware of, but borosilicate glass can typically be used for cooking or baking in a hot oven.
Cold glass is not safe to directly place in a preheated oven, and the drastic temperature change will shatter the glass. Therefore, it is suggested to let the food bring up to room temperature to protect the glassware.
If you are uncertain whether placing your glass dish in a hot oven is safe, refer to manufacturer’s manual, look for material that glass is made out of, and check the oven-safe symbol to prevent from breaking the glass dish.
