Pyrex Rectangular Dish With Lid
Lower PFAS concern, glass core is inherently safe; verify plastic lid composition if extra caution desired.
Pyrex rectangular dishes are made from borosilicate glass, which does not contain PFAS. The included plastic lid is the potential concern point; Pyrex does not publicly disclose its lid material or PFAS status. Standard polypropylene lids carry minimal PFAS risk, but the brand's silence on composition leaves some uncertainty.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
The dish itself is borosilicate glass, which is engineered to resist thermal shock and chemical leaching, it does not release lead, cadmium, or other heavy metals into food under normal cooking use. The plastic lid is the variable component; Pyrex has not publicly disclosed whether the lid uses BPA-free polypropylene or other polymers. Borosilicate glass is considered one of the safest food-contact materials available and is the reason laboratory glassware uses the same material.
The brand's record and disclosure
Pyrex (currently owned by Instant Brands Holdings) does not maintain a published PFAS disclosure policy and does not publicly detail plastic lid composition on product packaging or websites. The brand has no recent major safety recalls for this product line on file with the U.S. Consumer Product Safety Commission. Pyrex's silence on PFAS and polymer sourcing reflects a broader industry trend of minimal transparency rather than evidence of contamination.
How it compares in its category
Borosilicate glass roasting dishes are among the safest in their category because the material itself cannot leach harmful substances; ceramic alternatives carry contamination risk from glazes, and metal pans risk aluminum leaching. The plastic lid is a potential weak point shared across many glass-storage-with-lid products. Pyrex rectangular dishes occupy the mid-market segment and are more cautiously formulated than budget alternatives but offer no visible advantage over competitor glass brands like Anchor Hocking or OXO.
If you buy it
Use the glass portion up to the manufacturer's stated oven temperature limit (typically 500°F); avoid placing a cold dish directly in a hot oven, as borosilicate can still crack under extreme thermal stress. Hand-wash the plastic lid rather than run it through the dishwasher to minimize heat exposure and potential polymer degradation. Replace the lid if it becomes cracked, discolored, or develops an odor. Store food in the glass dish without the lid during microwave use to eliminate plastic-heat contact entirely.
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.”
Plastic lid polymer composition and leaching
Pyrex has not disclosed whether the lid is BPA-free polypropylene or contains other polymers. Heating plastic lids or repeated dishwasher exposure may increase leaching risk; no recalls specific to this product's lid are on record.
Thermal shock cracking of glass
Borosilicate glass is thermal-shock resistant but not immune; rapid temperature changes (e.g., cold dish to hot oven) can still cause fracturing, creating sharp glass hazard. This is a material property, not a manufacturing defect.
Lead or cadmium in glass
Borosilicate glass as a material class does not use lead or cadmium in its formulation. Pyrex products have no published history of heavy-metal contamination in the glass component.
Lid hinge or seal degradation over time
Plastic hinges and seals on lids may become brittle or lose fit after years of use or repeated heating. This is a durability concern rather than an acute chemical hazard, but loose seals may trap bacteria if used for food storage.
Manufacturing or supplier transparency
Pyrex does not publicly disclose where plastic lids are sourced or manufactured, limiting independent verification of polymer sourcing or contaminant screening. This is an information gap rather than evidence of hazard.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
