Is GrillPro 13-Inch Pizza Stone 98154 non-toxic? What it is made of
The GrillPro 98154 is constructed from cordierite ceramic, a magnesium-aluminum silicate compound engineered for thermal shock resistance and high-temperature cooking. Cordierite is chemically inert at cooking temperatures (typically rated to 500-900 degrees Fahrenheit) and does not leach heavy metals or require non-stick coatings that introduce Teflon-type coating or perfluorinated compounds. This material class has no documented history of glazing contamination with lead or cadmium in consumer-grade products.
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 fracture
Cordierite is resistant to thermal shock but brittle; rapid temperature swings or mechanical impact can initiate cracks. Fractured stones present sharp edges and reduced structural integrity during cooking.
Microcracking and particle release over time
Repeated thermal cycles can create microscopic surface crazing in ceramic materials. Evidence of food-contact particles entering food is not established, but consumers should inspect the surface periodically for visible damage.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lead
No lead or cadmium contamination has been documented in cordierite pizza stones as a category. Food-contact ceramic cookware in the US is not federally required to disclose glaze composition, but cordierite's inherent chemistry and lack of decorative glazes on this model minimize this risk.
Source, ATSDR ↗Mold or bacterial growth from moisture retention
Cordierite is porous and can retain water if stored damp. This presents no acute safety hazard but may support odor-causing microbes; proper drying before storage mitigates this.
How is this PFAS grade calculated?
The brand's record and disclosure
Broil Mama is a smaller cookware brand with no publicly documented safety controversies, recalls, or certification claims related to this pizza stone model. The brand maintains no published material safety data sheets or third-party certifications (NSF, FDA, etc.) for this product, reflecting the informal disclosure posture of many small cookware manufacturers. No evidence of material misrepresentation or safety violations exists in available public records.
How it compares in its category
Cordierite pizza stones show lower concern than cast iron (which can leach iron at acidic pH), steel (corrosion risk), and refractory clay (which may have undisclosed glazing). The 13-inch size positions this as a mid-range home-use product typical of mass-market offerings; larger commercial-grade stones and smaller novelty stones follow the same material safety profile. Pricing and build quality appear consistent with direct-to-consumer cordierite competitors.
If you buy it
Preheat the stone gradually (place it in a cold oven and heat to desired temperature over 15-20 minutes) to prevent thermal shock fracture, which is the primary wear mechanism for cordierite. Avoid sudden temperature changes such as moving a hot stone to a cold surface or washing it immediately after use; allow it to cool naturally. Do not use soaps or oils on the surface; brush off debris dry or rinse with hot water only. Cordierite stones typically show lower concern if uncracked; discard if deep cracks develop, as they can propagate and fragment during use.
