GreenPan · Pizza Stones & Ceramic Bakeware
Pizza & Baking Stone
Lower-concern option; ceramic non-stick formulations typically avoid PFAS, but verify specific product batch for peace of mind.
GreenPan's pizza and baking stones use ceramic-based coatings rather than Teflon-type coating or Teflon-family coating, positioning them as PFAS-free alternatives.
Brand says: “GreenPan markets its cookware as PFAS-free and uses ceramic non-stick coatings as an alternative to traditional fluoropolymers.”

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's pizza stone is composed of natural ceramic or stone material, which does not rely on synthetic non-stick coatings like Teflon-type coating (Teflon). Ceramic is chemically inert at typical cooking temperatures (up to 500F for most pizza stones) and does not off-gas harmful fumes when used as directed. The material itself poses minimal leaching risk because ceramic is fired at high temperature and does not contain the binders or plasticizers found in polymer-based cookware.
The brand's record and disclosure
GreenPan has built its reputation on PFAS-free cookware marketing and maintains transparency about avoiding synthetic fluorinated compounds in non-stick formulations. The brand has not faced documented recalls or safety warnings specific to ceramic bakeware products. While GreenPan's primary focus is non-stick cookware (where PFAS substitutes matter most), their ceramic stone products align with their stated commitment to safer materials.
How it compares in its category
Ceramic pizza stones are among the lowest-risk options in the baking stone category because they avoid both Teflon-type coating and proprietary ceramic coatings prone to wear. They compete with unglazed quarry tiles and cast iron, which are equally safe but less convenient. Compared to glazed ceramic stones from other brands, GreenPan's transparency reduces uncertainty about glaze composition.
If you buy it
Preheat the stone slowly to avoid thermal shock and cracking; place it in a cold oven and heat gradually to your target temperature. Do not immerse in water immediately after use; allow cooling first. Inspect the stone surface regularly for cracks or chips, which compromise function but do not create acute hazards. Clean with a damp cloth or soft brush; avoid scouring pads that may degrade the surface.
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 ceramic glazes
No recalls or test reports document lead/cadmium contamination in GreenPan pizza stones. Ceramic stones for cooking are typically unglazed or use food-safe glazes, though manufacturer glaze composition is not publicly detailed; if concerned, request specification sheet.
Thermal shock and cracking
Ceramic stones are prone to sudden cracking if exposed to large temperature swings (e.g., cold oven to 500F too quickly, or wet surface placed on hot stone). This is a mechanical failure, not a chemical hazard, but broken pieces can injure hands or contaminate food.
Coating degradation and particle shedding
Because this is uncoated ceramic rather than a polymer or metal with applied non-stick, degradation risk is minimal. Natural ceramic does not flake or peel over time under normal use.
Microplastic or ceramic particle migration
Fired ceramic does not shed microparticles into food at normal cooking temperatures. High-fired ceramic stones are chemically stable and do not degrade from repeated heating cycles.
Formaldehyde or volatile off-gassing
Ceramic pizza stones do not use binders, resins, or adhesives that would release formaldehyde or other VOCs during heating, unlike some pressed composite stone products.
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.
