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.
