Anchor Hocking 4-cup Round Kitchen Storage Bowl with Lid
Lower concern, glass bowl is PFAS-unlikely, but plastic lid leaves minor uncertainty.
Anchor Hocking's borosilicate glass storage bowl itself presents lower PFAS risk as a non-coated glass product. The plastic lid is the weak point: Anchor Hocking does not disclose its composition or any PFAS-avoidance commitment.

Why this grade
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
Category baseline
food packaging is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
The bowl is borosilicate glass, a chemically inert material that does not leach contaminants into food under normal use, heating, or storage. The lid is plastic, likely polypropylene (PP) or a proprietary polymer based on Anchor Hocking's product line, which introduces a potential vector for BPA or phthalates if the plastic contains these additives. Because the lid sits above rather than submerged in food and is not intended for heating, direct migration risk is minimal but not zero, especially if acidic or fatty foods contact the underside long-term.
The brand's record and disclosure
Anchor Hocking is a long-established U.S. glassware manufacturer with no major product recalls or public disclosures of BPA contamination in food storage products. The company does not publish detailed material safety datasheets for consumer products or disclose PFAS use in lid coatings. No independent recalls of this specific product for chemical safety are recorded, and the brand maintains a low-controversy profile in the food storage category, though transparency on plastic additives remains limited.
How it compares in its category
Borosilicate glass storage bowls are among the safest options in the food storage category because glass itself carries no leaching risk. This product is comparable to similar mid-tier offerings from Pyrex or OXO in material safety. The plastic lid is a standard compromise; premium alternatives (stainless steel or silicone lids) would reduce plastic contact entirely, but this design is typical and acceptable for the price point.
If you buy it
Avoid prolonged contact between acidic foods (citrus, vinegar, tomato) and the plastic lid, as this can increase migration of additives. Do not heat the lid or place it in the microwave or dishwasher if the manufacturer advises against it. Hand-wash the lid in cool water to minimize exposure of the plastic to heat. If the lid becomes visibly degraded, clouded, or odorous after months of use, replace it rather than continue using a compromised polymer.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
BPA/BPS in plastic lid
Anchor Hocking does not publicly disclose whether the plastic lid contains BPA or BPS. Standard PP lids in this category are often BPA-free but may contain other bisphenols or phthalate plasticizers. Risk is low because the lid is removable and food contact is indirect and not heated.
Phthalates in plastic lid
Polypropylene and other plastics used in storage lids may contain phthalate plasticizers to improve flexibility. No specific testing of this product's lid composition is publicly available. Acidic or fatty foods may increase migration slightly, though the amount is expected to be within acceptable daily intake limits.
Glass thermal shock or breakage
Borosilicate glass is designed to withstand thermal stress, but sudden temperature changes (e.g., from freezer to hot oven) can cause cracking. This is a use-error hazard, not a chemical safety issue, but important for consumers to understand.
Lid coating or adhesive leachables
No recalls or reports of coating degradation or adhesive leaching from this product's lid are documented. The lid design is standard and has been in use without reported chemical safety incidents.
Microplastics from lid degradation
With extended use and dishwasher exposure, the plastic lid may shed microscopic particles. The risk is low for normal hand-washing and storage conditions, but dishwasher cycles or abrasive cleaning may accelerate wear over years.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
