Material
Carbon steel with unspecified nonstick coating
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Non-stick, chemistry undisclosed
Advertised as non-stick but coating type is not explained.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Category baseline
cookware is a category where PFAS exposure is more common.
Nonstick coating degradation and particle release
Unspecified coating composition means thermal stability limits and aging behavior are unknown. Chipping or flaking would expose bare steel and release coating fragments into food.
Coating fume risk at high heat
If the coating is Teflon-type coating-based, temperatures above 500 F can produce polymer fume fever symptoms. Ceramic coatings are more heat-stable but still risk delamination. Brand silence on this threshold is a red flag.
Iron handle burn risk
Solid iron handles conduct heat directly from the pan. Users report rapid, severe burns if the handle is grasped without protection, especially during stovetop use. This is a design feature, not a chemical hazard, but material-relevant.
Coating adhesion and leaching under acidic food
Unspecified nonstick layer may not be stable under prolonged contact with vinegar, citrus, or tomato-based dishes. Coating failure risk depends on underlying adhesion chemistry, which is undisclosed.
What’s reassuring
Cadmium
Carbon steel composition is not disclosed; no public reports of heavy metal contamination in Mauviel cookware. However, European-manufactured carbon steel can occasionally include trace metals; verify alloy specification if concerned.

What it's made of and why it matters
This pan combines a carbon steel body with an unspecified nonstick coating and iron handles. Carbon steel itself is chemically inert and durable, but the nonstick layer's composition is the critical unknown. Mauviel's product listing does not disclose whether the coating is ceramic-based, Teflon-type coating (Teflon), or another polymer, which directly affects thermal stability and potential fume release at high heat.
The brand's record and disclosure
Mauviel is a heritage French cookware manufacturer known for professional-grade products, but public records show no PFAS-specific certification, third-party testing disclosure, or commitment statement regarding nonstick coatings. The product page lacks coating material specification, which is a significant transparency gap for a premium brand. No recalls or safety violations linked to this model are documented.
How it compares in its category
Carbon steel cookware sits between cast iron (no coating, higher maintenance) and traditional nonstick (often Teflon-type coating-based). This pan's appeal is durability and seasoning capability similar to cast iron, but with an expedient nonstick layer. Without coating transparency, it cannot be ranked confidently against Teflon-type coating-free ceramic alternatives or established Teflon-type coating brands with published safety data.
If you buy it
Contact Mauviel directly to request nonstick coating composition before purchase. If acquired, hand-wash only (dishwasher may degrade the coating). Keep heat below medium-high (around 400 F) until coating identity is confirmed, as high heat behavior is unpredictable. Monitor the coating surface yearly for chips, cracks, or peeling; discontinue use if degradation appears, as underlying steel exposure and coating particle ingestion become risks.
