Fox Run Round Pizza Stone
Lower concern since ceramic pizza stone avoids nonstick coatings and Teflon-family coating.
Fox Run's Round Pizza Stone is unglazed or ceramic-coated stoneware or clay, not a nonstick-coated cookware item. Pizza stones typically don't use Teflon-type coating or Teflon-family coating coatings.

Is Fox Run Round Pizza Stone non-toxic? What it is made of
The Fox Run Round Pizza Stone is ceramic-coated stoneware with an unglazed clay base. This construction avoids Teflon-family coating nonstick coatings (Teflon-type coating/PFOA) entirely, which eliminates fume-release risk at high heat. Unglazed ceramic and stoneware are relatively inert under normal baking temperatures (up to 500F+), though the ceramic topcoat's adhesion and composition depend on the firing process and glaze formulation used by the manufacturer.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Coating degradation and exposure of porous clay base
Repeated thermal stress and acidic foods (tomato sauce) can cause ceramic glaze crazing or peeling over years of use. Once the ceramic coating fails, the underlying stoneware becomes porous and may absorb liquids or harbor bacteria; unglazed clay itself poses no acute toxicity but loses its food-safe barrier.
Thermal shock cracking and microparticle release
Rapid temperature changes can cause stoneware to crack or chip. Small ceramic fragments in food are choking and dental hazards; no evidence suggests chemical toxicity from ceramic itself, but mechanical breakage is a documented user-injury risk with pizza stones.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lead
No specific recalls or test reports of heavy metal leaching from Fox Run pizza stones are on record. However, ceramic coatings on imported or budget stoneware can contain lead if manufacturing standards are lax. This product's country of origin and glaze certification status are not publicly disclosed.
Source, ATSDR ↗Teflon-type coating/nonstick fume risk
This product is unglazed ceramic without Teflon-family coating coatings, so no Teflon-type coating off-gassing risk is present. This is a significant safety advantage over modern nonstick bakeware.
Aluminum leaching
Ceramic and stoneware pizza stones do not contain aluminum. This hazard class is irrelevant to this product.
The full breakdown
The brand's record and disclosure
Fox Run is a kitchenware brand with minimal public disclosure on material safety testing, heavy metals screening, or chemical safety certifications. No major product recalls tied to ceramic pizza stones from Fox Run appear in FDA or CPSC records. The brand does not publicly address PFAS avoidance or publish third-party safety certifications for cookware products, suggesting a passive (rather than proactive) safety posture.
How it compares in its category
Unglazed ceramic and stoneware pizza stones have lower concern in the baking-surface category because they lack nonstick coatings and are naturally durable at high heat. Cast iron and steel alternatives carry iron leaching risk (minimal for most users); glazed ceramic risks lead/cadmium in older or imported coatings. The Fox Run product sits in the low-risk tier but offers no demonstrable safety advantage over comparable unglazed competitors.
If you buy it
Preheat slowly to avoid thermal shock cracking, and place the stone on the lower oven rack to prevent direct contact with heating elements. Avoid abrupt temperature changes (do not remove a hot stone and run it under water). Inspect the ceramic coating annually for chips or crazing; discard if the glaze shows significant damage or if you suspect coating loss, as this may expose porous clay. Hand wash gently; harsh abrasion or thermal cycling will degrade the surface over time.
