Le Creuset 15" Round Pizza Stone
Lower PFAS concern, unglazed or naturally glazed stoneware carries minimal fluorochemical risk.
Le Creuset pizza stones are made from fired stoneware (ceramic), a non-coated material with no known PFAS treatment. Ceramic cookware does not require nonstick coatings, water repellency treatments, or grease resistance, all common PFAS sources. No brand PFAS disclosure is needed because the material itself is a lower-risk category.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Le Creuset's 15-inch round pizza stone is fired stoneware, a dense ceramic material made from clay fired at high temperatures (typically 1200+ degrees Celsius). This manufacturing process creates a nonporous, durable surface that resists chipping and crazing better than earthenware. The glaze, if present, is typically a proprietary Le Creuset formulation applied before the final firing; because stoneware is not porous after firing, glaze adhesion is strong and leaching risk during normal cooking is very low.
The brand's record and disclosure
Le Creuset does not publicly disclose detailed glaze chemistry or testing protocols for heavy metals and lead, which is typical for premium cookware brands but limits independent verification. The company has no published recalls for this pizza stone model and no documented safety violations in U.S. regulatory databases. Le Creuset maintains ISO 9001 manufacturing standards and products sold in North America comply with FDA food-contact regulations, though the brand does not voluntarily exceed these minimum standards with third-party certification.
How it compares in its category
This stoneware pizza stone is mid-to-premium in the category; it competes with Emile Henry and Staub (both also stoneware) and undercuts specialty ceramic brands. Compared to unglazed quarry tiles or budget ceramic stones, Le Creuset's firing quality and glaze consistency are superior, reducing cracking and uneven heating. Cast iron and steel pizza pans offer slightly lower chemical leaching risk but poor heat distribution; stoneware is the safer choice for even crust development.
If you buy it
Preheat the stone in a 500F+ oven for 30+ minutes to avoid thermal shock cracking. Do not immerse in water; hand-wash with a damp cloth or soft brush and dry immediately to prevent moisture absorption into minor surface cracks. Replace if the glaze shows visible flaking, crazing, or discoloration from heat exposure (typically after 5-10 years of regular use). Avoid rapid temperature changes; remove from the oven and let it cool slowly on a rack to prevent warping.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Lead and cadmium in glaze
Le Creuset pizza stones are manufactured to FDA food-contact standards, which limit lead and cadmium in glazes. No recalls or documented testing failures have been published for this product line. However, the brand does not provide independent lab reports or third-party certification of glaze composition.
Glaze crazing and flaking
Stoneware glazes can develop fine cracks (crazing) over time with repeated thermal cycling, particularly in ovens with temperature fluctuations. While minor crazing does not necessarily indicate chemical release, visible flaking should trigger replacement. This is a durability issue rather than an acute safety hazard.
Thermal shock and breakage
Placing a cold or room-temperature stone directly into a hot oven, or removing it to a wet surface, can cause cracking or shattering. This poses burn and laceration risk to the user but is preventable with proper preheating and cooling practices.
Aluminum leaching
Stoneware is clay-based and contains no aluminum; this hazard class is not relevant to this product.
VOC off-gassing
Fired stoneware does not emit volatile organic compounds (VOCs) at typical cooking temperatures (up to 500F). No off-gassing has been reported for Le Creuset pizza stones.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 88% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
