Pyrex Easy Grab Oblong Baking Dish
Lower-concern buy, borosilicate glass is PFAS-free by material design.
Pyrex baking dishes are made from borosilicate glass, which contains no fluorine-based coatings or PFAS. Glass is an inert, non-coated material with no documented PFAS risk. No special claim or third-party verification needed; the material itself is the safeguard.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
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
Pyrex Easy Grab baking dishes are manufactured from borosilicate glass, a silica-based formulation engineered to resist thermal shock and chemical leaching. Borosilicate glass does not leach lead, cadmium, BPA, or other endocrine disruptors into food, even when heated repeatedly or exposed to acidic foods. The material is chemically inert across normal cooking temperatures (up to around 500°F for standard Pyrex), making it one of the safest cookware substrates available from a contamination standpoint.
The brand's record and disclosure
Pyrex (owned by Instant Brands) does not publicly disclose detailed manufacturing certifications or third-party safety audits for this specific product line, which is typical for legacy glass cookware brands. The company has no significant recalls related to leaching or toxic coatings for borosilicate baking dishes in the past two decades. Pyrex's silence on PFAS is consistent with the fact that borosilicate glass itself contains no intentional fluorinated compounds, so explicit messaging is not a priority for this material class.
How it compares in its category
Glass baking dishes are among the safest options in the cookware category, particularly compared to nonstick ceramic or traditional nonstick (Teflon-type coating-coated) alternatives, which carry fume and coating-degradation risks. Unglazed stoneware and cast iron are also inert but require seasoning maintenance; borosilicate requires none. The main tradeoff is weight and breakage risk versus the durability and thermal performance of metal or ceramic-coated pans.
If you buy it
Borosilicate glass can be used at temperatures up to approximately 500°F; avoid rapid temperature changes (e.g., moving from a cold counter directly into a preheated oven) to prevent thermal shock and cracking. Hand washing is recommended to extend handle durability and avoid dishwasher cloudiness over time, though the glass itself is not damaged by machine washing. Inspect the dish periodically for chips or cracks; small cracks can propagate during heating. Store away from hard impacts, as glass breakage is the primary failure mode.
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.”
Thermal shock / mechanical failure (breakage)
Borosilicate glass resists thermal shock better than soda-lime glass, but rapid temperature swings or impact can still cause cracking or shattering. This is a physical safety concern rather than a chemical one.
Lead or cadmium in glass formulation
Borosilicate glass formulations do not intentionally include lead or cadmium. No recalls or test data suggest contamination in Pyrex borosilicate baking dishes.
Handle coating or trim leaching
Pyrex Easy Grab models feature silicone or thermoplastic handles. No established recalls or reports of leaching from these handles into food under normal use conditions.
Microplastics from handle wear
Repeated contact between silicone or plastic handles and heat or abrasion could theoretically shed microparticles over years of use, though no documented evidence exists for Pyrex products specifically.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 92% 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.
