Pyrex Metal Bakeware 3-Piece Set
Lower PFAS concern, traditional baked enamel on metal poses minimal risk versus Teflon-family coating nonstick.
Pyrex metal bakeware uses carbon steel with standard baked enamel coating, not Teflon-family coating nonstick, making PFAS exposure unlikely. Pyrex does not market this as nonstick or make PFAS claims, which aligns with traditional enamel cookware manufacturing.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Pyrex Metal Bakeware uses carbon steel as the substrate with a baked enamel (vitreous enamel) topcoat, not nonstick Teflon-family coating. Baked enamel is a glass-like ceramic coating fused to metal at high temperature, creating a stable barrier that does not release volatile compounds during normal baking. This material class has a long safety history in kitchenware and avoids the Teflon-family coating concerns present in Teflon-type coating nonstick products.
The brand's record and disclosure
Pyrex (currently owned by Instant Brands) does not prominently disclose enamel coating composition or heavy metal testing on product pages for this bakeware line. The brand has not issued recalls for metal bakeware related to coating degradation or leaching in recent years. Pyrex maintains general FDA cookware compliance claims but does not provide third-party certification or detailed material safety data sheets for consumer access.
How it compares in its category
Baked enamel metal bakeware is a conventional, lower-risk option compared to aluminum sheet pans (which may leach aluminum under acidic conditions) or nonstick-coated sheets (which carry Teflon-type coating fume and wear-related risks). Carbon steel with enamel also avoids stainless steel's potential nickel leaching, making it a middle-ground choice. Performance-wise, enamel conducts heat evenly but requires more careful handling to prevent chipping than bare carbon steel.
If you buy it
Avoid metal utensils and scouring pads that can chip the enamel; use silicone or wood instead. Do not expose to thermal shock (e.g., hot pan to cold water), which can crack the coating. Hand wash rather than dishwasher to preserve the enamel; if chips appear, replace the pan to prevent rust exposure. Store in a dry location to prevent rust at edges or damaged areas.
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.”
Lead or cadmium in enamel glaze
No recalls or test results indicating heavy metal contamination in Pyrex branded enamel bakeware are on record. Baked enamel coatings can theoretically contain lead or cadmium if not manufactured to current FDA standards, but Pyrex products are marketed as compliant with US food contact regulations.
Coating degradation and rust exposure
Enamel coatings chip over time with mechanical stress or thermal shock, exposing the underlying carbon steel to rust formation. While small rust spots pose minimal acute risk, repeated use of heavily chipped cookware could allow iron compounds to enter food, though this is unlikely at significant levels in typical home use.
Aluminum leaching
This product is carbon steel, not aluminum, so aluminum leaching is not a concern. The enamel barrier prevents contact between the steel substrate and food.
Teflon-type coating fume risk
Baked enamel is not Teflon-type coating (Teflon); it does not release toxic fumes when overheated. Enamel cookware is safe to use at normal baking temperatures (up to 500F typical household oven range).
Nickel leaching from stainless steel
This product is carbon steel with enamel coating, not stainless steel, so nickel exposure is not relevant.
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.
