Pyrex Glass Food Storage Containers vs. Reusable Glass Drinking Straw

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

Common claims

• Plastic-free sipping
• Dishwasher safe
• Won't affect taste

Concerns / watch-outs

• Breakable if dropped or bitten hard
• Should come with a cleaning brush for thorough washing

Notes

Borosilicate glass straws are completely inert and don't leach. An excellent alternative to plastic or single-use straws.

Cleaner alternatives

• glass water bottle
• stainless water bottle
