Lodge Cast Iron · Pizza Stones & Ceramic Bakeware
Baking Stone, Glazed Ceramic 13-in for XL 400, LG 300, JR 200, Kamado - PG00340
Lower PFAS concern, plain glazed ceramic baking stone carries minimal fluorochemical risk.
This is a glazed ceramic baking stone for kamado-style grills. Ceramic glazes are not typically formulated with PFAS, and Lodge has not disclosed use of Teflon-family coating coatings in this product line. No third-party testing data is publicly available, but the material itself is inherently lower-risk than nonstick cookware.

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
This is a solid ceramic stone with a glazed surface, designed to absorb and distribute heat evenly in Kamado-style ovens. Ceramic itself is inert at baking temperatures (under 900°F). The glaze is a glass-like coating that seals the porous ceramic body and prevents direct food contact with raw clay. Lodge has not disclosed specific glaze formulations for this model, but plain ceramic glazes used on food-contact bakeware typically contain feldspar, silica, and clay with minimal heavy metal pigments.
The brand's record and disclosure
Lodge Cast Iron is a legacy American cookware manufacturer known for cast iron and enameled products. The company does not publish PFAS or heavy metal testing data for ceramic baking stones on its website. Lodge maintains some third-party certifications for cast iron (FDA compliance) but has not pursued formal certifications specific to glaze safety for this ceramic product. No major recalls or safety controversies are on record for Lodge ceramic baking stones.
How it compares in its category
Glazed ceramic pizza stones are among the safest baking surfaces available because they are fired at high temperature, making the glaze very stable and unlikely to shed or leach under normal use. This contrasts with non-stick surfaces (which may release Teflon-type coating fumes if overheated) or unglazed ceramic (which can absorb water and crack). Lodge's version is competitively priced and sized for large ovens; it occupies the middle-to-mainstream segment of the ceramic bakeware market.
If you buy it
Preheat gradually to avoid thermal shock and cracking. Do not exceed 900°F, which is well above typical pizza-stone use (600-800°F). Inspect the glaze surface for chips or cracks before each use; discard if large cracks develop, as moisture can then enter the ceramic body and cause spalling. Clean with hot water only; avoid soap or abrasive scrubbing that may dull the glaze. Store in a dry location to prevent water absorption.
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 glaze
No documented lead or cadmium contamination in Lodge ceramic bakeware. Plain ceramic glazes used in food-contact cookware are formulated to meet FDA limits. Lodge does not disclose glaze composition for this model, so independent verification is not publicly available.
Glaze degradation and ceramic cracking over time
Ceramic is prone to thermal shock if heated or cooled rapidly, which can cause visible cracks in the glaze and underlying ceramic. Once cracked, the stone can absorb moisture and develop spalling. This is a durability concern rather than a chemical safety issue but may allow food contact with unglazed ceramic after damage.
Aluminum or metal leaching from ceramic body
Ceramic baking stones do not contain added aluminum and are not designed to leach metal. The clay body may contain trace minerals, but firing seals the structure. No evidence of leaching from ceramic pizza stones into food has been documented in safety literature.
Chromium or other heavy metals in colorant pigments
This stone is described as glazed ceramic in a neutral finish; no decorative pigments or high-color coatings are mentioned. Plain glazes used on functional cookware typically avoid chromium or other restricted pigments. Lodge does not disclose specific pigment use for this model.
Bacterial growth or mold on porous ceramic surface
Unglazed or chipped ceramic can harbor moisture and microbial growth if stored damp. The glaze on this stone is intended to prevent absorption, but cracks or chips can compromise that seal. Proper drying and storage in a low-moisture environment minimizes risk.
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.
