FAQ:

Q: Can I use Pyrex hot/cold packs to heat up lasagna?

A: We also purchased a lasagna carrier and used these Pyrex hot/cold packs with that. We did a test run with Pyrex glass containers filled with boiling water and placed in the carrier with the heated Pyrex hot/cold packs. Checking at intervals for water heat retention, it was still very hot at 4 hours and acceptably hot at 6 hours.

Q: Are Pyrex lids BPA free?

A: Pyrex® glassware plastic lids are BPA free. They are safe for use in the microwave and for food storage. Pyrex® lids cannot be placed in conventional or convection ovens (because they’ll melt), unless specifically noted on the package that they are designed for oven use (as with Pyrex® Ultimate Storage silicone and glass lids).

Q: How do you store cooked food in Pyrex?

A: Place it on a dry cloth or potholder, or on a wooden trivet or cooling rack. Allow Pyrex to come to room temperature before immersing in water or placing in the freezer, refrigerator, microwave or pre-heated oven. Don’t use Pyrex to microwave popcorn or heat foods in browning wrappers.

Q: Can Pyrex lids go in the oven?

A: Pyrex® lids cannot be placed in conventional or convection ovens (because they’ll melt), unless specifically noted on the package that they are designed for oven use (as with Pyrex® Ultimate Storage silicone and glass lids). Pyrex® glassware and lids are dishwasher safe, making cleanup easy and carefree.
