Is it safe to use Pyrex in the oven? Here’s what most people are missing

Preheating:

When using Pyrex in the oven, it’s a good practice to preheat the oven with the Pyrex dish inside. This helps to gradually increase the temperature of the glass and reduce the risk of thermal shock.

Avoid Direct Flame:

Do not expose Pyrex glassware to direct flames or use it on a stovetop. It is designed for oven use and may not withstand direct heat from gas burners or open flames.

Check for Damage:

Before using any Pyrex dish in the oven, inspect it for chips, cracks, or scratches. Damaged glassware is more likely to break when exposed to heat.

Is thermal shock a concern?

Yes, thermal shock is a significant concern when using glassware like Pyrex in the oven, particularly if you have Pyrex products made from soda-lime glass. Thermal shock occurs when there is a rapid and extreme temperature change, causing the glass to expand or contract unevenly, which can lead to cracking or shattering.

To prevent thermal shock, avoid rapid temperature changes, such as placing cold Pyrex into a hot oven or exposing it to direct flames. It’s advisable to preheat the oven with the Pyrex dish inside and use oven-safe temperatures as recommended by the manufacturer. Always inspect your Pyrex for damage like chips or cracks before using it in the oven to reduce the risk of breakage.

In conclusion, it is generally safe to use Pyrex in the oven, but there are some important considerations to keep in mind. The safety of your Pyrex glassware depends on its type (borosilicate or soda-lime glass) and how you use it. If you have older Pyrex products made of borosilicate glass, they are more heat-resistant and less likely to shatter. However, newer soda-lime glass Pyrex products require more careful handling to avoid breakage. Always follow the manufacturer’s instructions and exercise caution to ensure the safe use of Pyrex in the oven.
