Sur La Table Cordierite No-Slip Pizza Stone
Cordierite base is lower concern; no-slip coating composition unclear.
Cordierite pizza stone itself is a mineral material without inherent PFAS risk. The no-slip coating remains unspecified by brand, creating uncertainty about surface treatment composition.

Material
Cordierite stone with no-slip coating, type unspecified
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Non-stick, chemistry undisclosed
Marketed non-stick without stating the coating chemistry.
Category baseline
cookware is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Coating degradation and migration
The no-slip coating composition is not disclosed. Repeated thermal cycling at pizza-oven temperatures (800-900 F) may cause degradation; unknown formulations could theoretically release adhesives or polymer fragments if compromised.
Teflon-type coating or Teflon-family coating fume hazard
No-slip coatings are sometimes Teflon-type coating-based, though Sur La Table has not confirmed this. If the coating contains Teflon-type coating, exposure to temperatures above 500 F (which pizza stones routinely exceed) could theoretically emit perfluorinated compounds; PFAS grading separately reflects this concern.
What’s reassuring
Lead
Cordierite itself does not contain lead or cadmium in natural form. No safety recalls or contamination reports have been documented for Sur La Table cordierite stones. However, unspecified coatings are a minor risk vector if sourcing is uncontrolled.
Source: ATSDR ↗Aluminum leaching
Cordierite contains bound aluminum in its silicate matrix; aluminum does not leach appreciably from intact cordierite under normal cooking conditions. Risk only arises if the stone surface is severely compromised or coating strips away, exposing raw mineral.
The full breakdown
What it's made of and why it matters
Cordierite is a naturally occurring magnesium-alumina silicate mineral prized for pizza stones because it resists thermal shock and does not require seasoning. The concern here is the no-slip coating, which Sur La Table has not publicly specified by type or chemical composition. Coatings on cookware can degrade with heat cycling, and if the formulation includes certain polymers or adhesives, degradation products could migrate to food at high oven temperatures typical for pizza baking (800-900 F).
The brand's record and disclosure
Sur La Table is a cookware retailer/designer but does not appear to have published detailed material safety data sheets or coating compositions for this specific product. The brand has not issued recalls related to this stone based on available records. No third-party certifications (NSF, California Prop 65 compliance statements) have been identified for this item, leaving the no-slip formulation opaque to consumers.
How it compares in its category
Uncoated cordierite pizza stones are standard and pose minimal leaching risk. The addition of a proprietary no-slip coating distinguishes this product but introduces uncertainty absent from bare-stone alternatives. Many competing brands (Emile Henry, Le Creuset) either use uncoated cordierite or fully disclose their coating chemistry, making this product's opacity a relative weakness in the category.
If you buy it
Preheat gradually to avoid shock to the coating. Inspect the surface regularly for cracks, peeling, or discoloration; replace the stone if the no-slip coating degrades noticeably. Clean with dry methods (brush) or minimal water to reduce coating stress. Avoid prolonged storage in high-humidity environments, as moisture ingress at coating edges can promote delamination.
