Dos and Don’ts
- Do follow manufacturer’s instructions: Different Pyrex products may have specific instructions or recommendations for microwave use. It's essential to read and follow the guidelines or instructions the manufacturer provides to ensure safe and optimal usage.

- Do allow Pyrex cool down before cleaning: After microwaving, allow the Pyrex to cool down to a safe temperature before cleaning or immersing it in cold water. Rapid temperature changes cause thermal stress and potentially lead to breakage.
- Don’t microwave an empty Pyrex dish: ideally you should never put an empty dish in the microwave as the microwave needs food molecules to heat up. Microwaving an empty dish will not only damage it but will damage the microwave itself. we discuss this in our how to use a microwave.

- Don’t subject it to extreme temperature changes: Despite its enhanced thermal shock resistance, you should refrain from transferring Pyrex directly from the freezer to the microwave or placing hot Pyrex in the refrigerator immediately after microwaving.
Our best tips
- Allow Pyrex to reach room temperature before subjecting it to extreme temperature variations.
- To accommodate varying microwave powers, adjust cooking times accordingly. Begin with the shortest recommended time and check for doneness. If needed, continue microwaving in short intervals until your food is evenly cooked.
