Mason / Ball Glass Jar vs. Glass Food Storage with Snap Lids

Materials

• Soda-lime glass
• Steel lid with plastisol sealant

Common claims

• Airtight seal
• Reusable
• Dishwasher safe

Concerns / watch-outs

• Plastisol lid liner may contain BPA in some manufacturers' lids — BPA-free replacement lids are widely available
• Glass can break if dropped

Notes

One of the most trusted, inert food storage vessels. Switch to BPA-free lids (widely available) for the cleanest setup.

Cleaner alternatives

• borosilicate glass container
• stainless steel food container

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
