Pyrex Glass Food Storage Containers vs. Glass Food Storage with Snap Lids

Materials

• Tempered soda-lime glass
• Plastic or silicone lids

Common claims

• Oven, microwave, and dishwasher safe
• BPA-free lids
• Non-porous glass

Concerns / watch-outs

• Modern Pyrex sold in the US uses tempered soda-lime glass, not borosilicate — more susceptible to thermal shock than older versions
• Plastic lids may contain BPA; look for confirmed BPA-free lids or use silicone alternatives

Notes

Pyrex glass is one of the most recommended non-toxic food storage options. The glass body is completely inert. Replace plastic lids if they become scratched or stained.

Cleaner alternatives

• borosilicate glass container
• mason jar

Materials

• Borosilicate glass
• BPA-free plastic snap lids

Common claims

• Oven, microwave, and freezer safe
• Non-porous glass
• BPA-free lids

Concerns / watch-outs

• Lids are typically polypropylene (PP) — avoid microwaving with lid on
• Glass can break if dropped on hard floors

Notes

Best practice for food storage. Glass body is completely inert. Just don't microwave with the plastic lid on to avoid leaching.

Cleaner alternatives

• pyrex glass containers
• anchor hocking glass
