Can you put glass pyrex in the oven? Yes, you can put glass Pyrex in the oven. It is great dish to prepare, store, cook, bake, and reheat food in the oven.
Pyrex is made using borosilicate glass that makes it thermal shock resistant and oven-safe up to 425 degrees Fahrenheit or 218 degrees Celsius.
However, uneven heating or sudden temperature changes can cause glass to shatter or break.
Pyrex glass is not only perfect for cooking, but also food storage and meal prep containers to save time and make cleanup effortless. The ability to withstand high heat of Pyrex dishes makes it an essential cookware to own in every kitchen.
This article discuss safe ways to use Pyrex glass in the oven. Answered below are frequently asked questions about the proper care and guidelines to follow when using Pyrex glass in an oven.
How do I know if my Pyrex is oven safe?
Pyrex glass is known for being high heat resistant up to 425 degrees Fahrenheit, which makes it the most durable glass cookware in the industry.
Not only does it ave an oven-safe symbol on the bottom of the glassware, it is a tempered borosilicate products. As a result, it reduces the risk of thermal shock or rapid temperature changes affecting the glass when used in an oven.
However, uneven heating, direct contact with heating elements and sudden temperature changes may cause Pyrex glass to shatter or break.
To safely use Pyrex in the oven, the manufacturer recommends preheating the oven before placing the glass dish inside so it does not exposed to direct changes in temperature.
Additionally, let the dish come to room temperature before placing in a hot oven.
What temperature is Pyrex safe in oven?
According to the manufacturer, Pyrex is resistant to thermal shock and safe in the oven up to 425 degrees Fahrenheit or 218 degrees Celsius.
Additionally, it may go directly from the freezer at a temperature of -20 degree Celsius into the oven at a temperature of 200 degree Celsius. Though this has been tested and proven to work, drastic differences in temperature are not recommended for glassware because it may shatter.
This is the advantage of Pyrex glass made out of borosilicate glass and tempered to support extreme temperature changes.
However, it is not safe when used under the broiler or stovetop cooking.
Overtime and with frequent use, there may create invisible micro-cracks that lead to shatter when exposed sudden temperature changes.
Always take precautions to avoid shattering inducing fully preheating the oven before placing the glassware inside, covering the bottom of the dish with a little liquid, placing hot glassware on a dry cloth, never place the Pyrex directly on a burner or cold surface.
Additionally, never transfer directly to freezer from the oven or oven from freezer without allowing the dish to completely come to room temperature.
Can I put cold Pyrex in a hot oven?
No, you should not put cold Pyrex in a hot oven. Pyrex does not do well when placing cold glass on a hot surface because thermal shock causes the glass to expand and break, crack or shatter.
The manufacturer suggests avoiding sudden temperature changes to glassware.
Although Pyres it built to withstand thermal shock, rapid changes in temperature creates micro-cracks that can be invisible at first but may shatter at some point overtime.
Therefore, be sure to allow cold Pyrex glassware to thawing or bring up to room temperature instead of transferring a dish from the freezer to hot oven.
Can Pyrex go in 450 degree oven?
No, Pyrex should not go in a 450 degree oven because it may shatter or break at this high heat. The manufacture recommends temperatures at or below 425 degrees Fahrenheit or 218 degrees Celsius.
According to the manufacturer’s manual, the Pyrex glassware is oven-safe up to 425 degrees Fahrenheit, and it is not recommended to exceed the temp.
Even though it is tempered glass, the extreme high temperature may shatter at this setting. Furthermore, broiler or stovetop heating is not suggested.
Pyrex in Oven: Conclusion
Pyrex clear glass cookware offers even browning to the food, easy to monitor progress and simple cleaning. But understanding the proper way to use the glassware in the oven is highly recommended.
Made out of tempered borosilicate glass, Pyrex has built in heat resistance and thermal shock that makes it a popular item for many households.
It is oven-safe up to 425 degrees Fahrenheit or 218 degrees Celsius, but with uneven heating and sudden changes from cold to hot may cause the glass to break. Therefore, it is not recommended to exceed the temperature setting in an oven.
Look for the oven-safe symbol at the bottom of the glassware and refer to manufacturer’s guide to find the maximum temperature to prevent from breaking. If you use Pyrex glass properly, it will last a lifetime.
