Learn how to safely freeze food in glass containers, which types work best, and simple tips to prevent cracking or shattering.
Quick answer
Yes, you can freeze food in glass containers, but not all glass is created equal. Tempered glass and borosilicate glass are your safest bets. Avoid sudden temperature changes and always leave headspace for expansion.
Which glass types are freezer safe?
Tempered glass, like Duralex's iconic Picardie and Provence series, is designed to withstand thermal shock better than ordinary glass. This makes it a reliable choice for freezing liquids and leftovers. Borosilicate glass is another excellent option, but many everyday table glasses are not made from it.
How to prepare glass containers for the freezer
Cool food completely before transferring it to a glass container. Hot food can stress the glass and cause cracks. Leave at least an inch of headspace because liquids expand when frozen. Use a lid or wrap tightly to prevent freezer burn and odor absorption.
What to avoid when freezing glass
Never place a glass container directly from the freezer into a hot oven or microwave. Let it thaw gradually in the refrigerator. Avoid stacking heavy items on top of glass containers in the freezer, as pressure can cause breakage.
Frequently asked questions about freezing glass containers
- Can all glass containers go in the freezer?
- No. Only tempered or borosilicate glass is reliably freezer safe. Ordinary soda-lime glass is more likely to crack. Check for a 'tempered' or 'freezer safe' label before freezing.
- How long can I keep food in glass in the freezer?
- Most foods keep well for 2-3 months in a sealed glass container. For best quality, use within that window. Label containers with the date to track freshness.
- What should I do if my glass container cracks in the freezer?
- Discard the food and the container. Cracks can harbor bacteria, and the glass may shatter later. Always inspect containers before reuse. Inspect glass regularly for any hairline cracks.
