Broil King · Pizza Stones & Baking Surfaces
15 Inch Round Ceramic Composite Pizza Stone
Lower concern. Ceramic composite pizza stones rarely contain PFAS.
Pizza stones are typically fired clay or ceramic without nonstick coatings or water repellents. Broil King does not disclose PFAS status, but ceramic composite materials carry minimal PFAS risk.

Is 15 Inch Round Ceramic Composite Pizza non-toxic? What it is made of
Ceramic composite pizza stones combine fired clay or ceramic material with mineral binders to create a porous, heat-retaining cooking surface. The composite structure allows even heat distribution and mimics traditional brick ovens without the brittleness of pure ceramic. Broil King's ceramic composite formulation is not detailed publicly, but this material class does not typically involve synthetic polymer coatings, enamel glazes with lead or cadmium, or Teflon-type coating (Teflon). Porosity is the intended feature; some mineral dust or small particles may shed initially or with wear, but this is cosmetic rather than a safety hazard at normal baking temperatures (typically 450-550F for home pizza ovens).
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.
Thermal shock and structural failure
Ceramic composite stones can crack if exposed to rapid temperature changes (e.g., hot stone placed on cool surface or rinsed with cold water). Cracks reduce performance but do not create direct chemical hazards; risk is physical (broken pieces) rather than toxicological.
Mineral dust or fines shedding
Porous ceramic composite may release fine dust particles, especially when new or if the surface is scratched or abraded. Ingestion of small amounts is not documented as a hazard, but visible debris should be brushed away before cooking. Prolonged inhalation of ceramic dust (e.g., during extended grinding or cutting of the stone) is occupational concern, not consumer use risk.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lead
No glaze, enamel, or ceramic coating is documented on this product. If the stone has a decorative surface finish or colored layer, Broil King has not disclosed its composition; independent testing would be required to rule this out definitively.
Source, ATSDR ↗Teflon-type coating (Teflon) and fume risk
Ceramic composite pizza stones do not use Teflon-type coating-based non-stick coatings. This hazard class does not apply to this product type.
Aluminum leaching
Ceramic composite is not aluminum-based cookware. Aluminum leaching does not occur with this material at typical cooking temperatures (450-550F).
The full breakdown
The brand's record and disclosure
Broil King is a subsidiary of Implus Corporation and manufactures outdoor cooking equipment and accessories. The brand does not publicly disclose detailed material safety testing or third-party certifications for this pizza stone. No recalls or safety controversies specific to this product or brand cookware line are on record. The company maintains no stated position on PFAS in cookware, which is typical for ceramic composite products in this category.
How it compares in its category
Ceramic composite pizza stones are considered lower-hazard compared to glazed ceramic or enameled cast iron cookware, which may contain lead or cadmium in decorative glazes. They pose no Teflon-type coating fume risk (unlike non-stick coated alternatives) and do not leach aluminum. Pizza stones in general are among the simpler cookware items; the main durability concern is thermal shock (rapid cooling) causing cracks, not chemical leaching. Broil King's product sits in the mainstream mid-range segment with no documented advantage or disadvantage versus generic ceramic composite competitors.
If you buy it
Season or cure the stone before first use by heating it gradually (follow package instructions) to reduce dust and stabilize the porous matrix. Use on a stable oven rack to avoid thermal shock; do not rinse with cold water immediately after use or subject it to sudden temperature swings. Check for cracks or deep chips before each use; once structural integrity is compromised, replace it. Clean with a dry brush or soft cloth; harsh detergents are unnecessary and may accelerate surface breakdown.
