Why Switch to Glass?
Plastic food containers can shed millions of microplastic particles into your food, especially when heated or scratched. A 2023 study found that microwaving a plastic container could release over 4 million microplastic particles per square centimeter. Glass, being an inert material, doesn't pose this risk. It won't leach chemicals, absorb food odors, or stain, making it the safest choice for your family.

Check price on AmazonFrequently Asked Questions (FAQ)
Are glass food-storage containers really safer than plastic?
Yes. Glass is inert and won’t leach chemicals or shed microplastics. While modern plastic is better, studies show all plastics can release particles, especially with heat or wear.
Can I put these in the oven or microwave?
Yes, all our picks are microwave and oven-safe (without the lids). Borosilicate glass handles temperature changes best. Always remove lids before heating in an oven.
Do the plastic lids last?
With proper care (top-rack dishwasher, no microwaving), lids should last for years. Brands like Pyrex offer affordable replacement lids.
What’s the difference between borosilicate and tempered glass?
Borosilicate glass is best for rapid temperature changes (freezer to oven). Tempered glass is stronger and more resistant to breakage from drops. Both are excellent for food storage.
Care & Maintenance Tips
- Avoid sudden extreme temperature changes to prevent cracking.
- Remove lids before microwaving or place them loosely on top. Never put lids in the oven.
- Clean silicone gaskets regularly to prevent mold and odors.
- Stack containers carefully, placing a paper towel between them to prevent chipping.
- If a container chips or cracks, stop using it for safety.
