GreenPan Reserve Ceramic Nonstick Bakeware Quarter Sheet Pan
Lower concern; ceramic nonstick bakeware with credible PFAS-free positioning, though no third-party lab verification available.
GreenPan Reserve uses Thermolon, a ceramic-based nonstick coating the brand explicitly claims is PFOA and Teflon-type coating-free and does not rely on Teflon-family coating.
Brand says: “GreenPan markets its Thermolon coating as PFOA-free and PTFE-free, emphasizing use of sand-derived minerals in the nonstick layer.”

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
Brand-stated PFAS-free
The brand states the product is PFAS-free (self-declared).
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
GreenPan Reserve uses Thermolon, a proprietary ceramic nonstick coating applied to a metal (likely steel or aluminum) substrate. Thermolon is marketed as PFOA and Teflon-type coating-free, relying instead on a ceramic-type ceramic matrix. The coating is baked at high temperature to bond it to the pan. Unlike legacy Teflon (Teflon-type coating), ceramic coatings do not off-gas fluorinated compounds under normal cooking temperatures, eliminating fume inhalation risk.
The brand's record and disclosure
GreenPan has publicly committed to PFAS-free manufacturing and has not faced major safety recalls related to nonstick coatings. The brand is owned by Groupe SEB and markets extensively on ceramic nonstick safety. While Thermolon composition is proprietary and not independently lab-verified in public domain, GreenPan's positioning is consistent across product lines. No credible reports of coating failure, leaching, or health incidents tied to their ceramic bakeware are on record.
How it compares in its category
Ceramic nonstick bakeware sits between traditional non-stick (Teflon-type coating-based, potential fume risk) and bare metal or stainless steel (no coating hazards but requires greasing). GreenPan's Reserve line is a mid-to-premium option; ceramic coatings degrade faster than Teflon-type coating under mechanical wear, but carry lower chemical risk. Quarter sheet pans in this category are functionally similar; GreenPan's main differentiator is the PFAS-free commitment rather than unique safety advantages.
If you buy it
Hand-wash gently to avoid coating scratches; abrasive scrubbers and the dishwasher accelerate degradation. Use silicone or wood utensils, never metal. Do not exceed 400-500°F; ceramic coatings can chip or degrade if exposed to rapid temperature swings or extremely high heat. Replace the pan if the coating shows visible flaking or large bare patches, as exposed substrate may leach metals during use. Store flat to prevent warping.
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.”
Coating degradation and substrate exposure
Ceramic nonstick coatings are more prone to chipping and wear than Teflon-type coating. If the coating flakes significantly, the underlying aluminum or steel substrate may contact food; prolonged exposure could result in trace metal leaching. GreenPan does not publish durability guarantees specific to this pan model.
Aluminum leaching (if substrate)
If the substrate is uncoated aluminum or aluminum with thin ceramic coverage, acidic foods (tomato, vinegar, citrus) may cause trace aluminum to dissolve into food over time. No public testing of GreenPan Reserve quarter sheet pan substrates is available; aluminum leaching from damaged nonstick cookware is a known but typically low-risk concern at normal use levels.
Teflon-type coating/fume inhalation risk
Thermolon does not contain Teflon-type coating. Ceramic coatings do not off-gas at typical kitchen temperatures. Overheating to 500°F+ may degrade the coating, but does not produce the acutely toxic fumes historically associated with overheated traditional Teflon.
Lead or cadmium in coating or glaze
No recalls or published test results indicate lead or cadmium contamination in GreenPan ceramic coatings. Thermolon is a silica-based proprietary formula; heavy metal presence is not a documented issue for this brand, though third-party lab verification is absent from public records.
Proprietary coating composition transparency
Thermolon's exact chemical composition is not disclosed publicly, limiting independent verification of all ingredients. GreenPan markets it as PFAS-free and Teflon-type coating-free, but full chemical transparency would require manufacturer disclosure or third-party testing not currently in the public domain.
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.
Formulations and coatings change between production runs. Always check the current label before buying.
