Broil King · Pizza Stones & Baking Surfaces
Broil King Rectangular Pizza Stone
Lower PFAS concern for pizza stones, though glazes warrant some caution if PFAS avoidance is critical.
Pizza stones are typically unglazed cordierite or ceramic with minimal PFAS risk. Broil King hasn't publicly addressed PFAS and glazed surfaces may carry legacy PFAS treatments, but pizza stones see indirect food contact.

Is Broil King Rectangular Pizza Stone non-toxic? What it is made of
Broil King pizza stones are typically cordierite ceramic, a silicate mineral engineered for thermal shock resistance and even heat distribution. Cordierite is chemically stable at high temperatures (commonly used to 400+ degrees Fahrenheit) and does not leach aluminum or other metals under normal pizza-making conditions. If this product is unglazed, there is minimal surface risk; if glazed, the glaze composition becomes the primary concern, particularly the colorants and binders used on food-contact surfaces.
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.
Lead
If this stone features colored glaze or decorative coating, risk exists for lead/cadmium in pigments or binders. Unglazed cordierite avoids this entirely. Request material safety data or avoid heavily decorated/glossy surfaces.
Source, ATSDR ↗Ceramic coating degradation over time
Glazed pizza stones can chip or crack with thermal cycling and use, potentially exposing underlying ceramic. Inspect regularly and discard if glaze flakes visibly into food.
Thermal shock fracture
Cordierite is engineered to resist thermal shock but is not immune. Rapid temperature changes (e.g., removing stone from oven and placing on wet surface) can cause cracking, which creates food contamination pathways.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Moisture absorption and microorganism growth
Porous ceramics can retain moisture in storage, potentially supporting mold or bacterial growth if stored damp. Proper drying and ventilation mitigate this.
Aluminum leaching
Cordierite is not aluminum-oxide based and does not leach aluminum under normal cooking temperatures. This is not a concern for cordierite pizza stones.
The full breakdown
The brand's record and disclosure
Broil King is a reputable outdoor cooking equipment manufacturer owned by Middleby Corporation, but publicly available safety certifications or third-party testing specific to this pizza stone are not widely documented. The brand has not made a public stance on PFAS or heavy metal testing for pizza stones, which is typical for this product category. No recalls or safety controversies specific to Broil King pizza stones have been recorded in public databases.
How it compares in its category
Cordierite pizza stones are a standard choice and generally lower concern than lower-cost ceramic alternatives made from common earthenware, which may have glazes with lead or cadmium. This product sits in the mid-to-premium segment where material quality is typically higher. Most established brands in this category do not publish detailed glaze safety data, so this product is representative of typical market transparency levels.
If you buy it
Season the stone with a light oil application before first use to condition any porous surface and check for visible damage or chipping. Do not expose to rapid temperature changes (avoid cold water on a hot stone) to prevent cracking. Replace the stone if chips appear or if glazing (if present) becomes visibly worn or flaking. Store in a dry location; moisture absorption in porous ceramics can cause issues over years of use.
