Is Cuisinart Alfrescamore Pizza Grilling non-toxic? What it is made of
The Cuisinart CPS-013 is manufactured from cordierite, a naturally occurring magnesium aluminum silicate mineral selected for pizza stones because of its low thermal expansion and high heat tolerance (typically rated to 2000°F). Cordierite does not leach heavy metals or harmful compounds under normal cooking conditions. Unlike some ceramic coatings or enameled cookware, cordierite requires no surface treatment and remains chemically stable when exposed to food, moisture, and high heat.
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 cracking
Rapid temperature changes or direct exposure to water can cause cordierite to fracture. Fragments risk ingestion or injury; no chemical hazard, but physical integrity matters for food safety.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lead
Cordierite is a natural silicate mineral with no established lead or cadmium content in food-grade products. Cuisinart does not disclose third-party testing, but no recalls or hazard reports exist for this product line.
Source, ATSDR ↗Microcracking and microplastic shedding
Cordierite is a hard mineral that does not degrade into microplastics when heated. Minor surface dusting from rough handling is theoretically possible but not documented as a food safety concern in this product category.
Coating or glazing toxicity
The CPS-013 is unglazed cordierite with no ceramic coatings, enamels, or surface treatments that could leach compounds. This design eliminates coating-related hazards common in some ceramic bakeware.
Heavy metals
Cordierite does not leach aluminum, lead, or other metals into food under normal pizza stone use (up to 500°F typical oven temperatures). The material's chemical inertness is well established for food contact applications.
Source, FDA ↗The full breakdown
The brand's record and disclosure
Cuisinart does not publish explicit food-contact safety certifications or test reports for this specific product. The brand has no major recalls related to cordierite baking stones and maintains general cookware safety compliance with FDA regulations for direct food contact. Cuisinart's marketing materials do not claim special safety certifications (e.g., lead-free testing), which is typical for cordierite products but reflects limited transparency compared to premium kitchenware brands.
How it compares in its category
Cordierite pizza stones are the industry standard and show lower concern in this material class, preferred over ceramic, clay, or cast iron alternatives that may crack or chip. The Cuisinart CPS-013 is mid-range in price and material quality; premium brands (e.g., Emile Henry) offer identical cordierite chemistry with stronger brand transparency. Budget alternatives sometimes use lower-grade ceramic that may contain lead in glazes or exhibit higher thermal shock risk.
If you buy it
Preheat the stone gradually in the oven (avoid direct high heat initially) to prevent thermal shock and cracking. Never submerge or rapidly cool the stone with water after use; allow it to cool naturally. Inspect for visible cracks before each use, as cracks may expand during heating and fragment food contact surfaces. Expect the stone to discolor or stain with repeated use; this is normal and does not indicate contamination.
