Smithey No. 10 Cast Iron Skillet

C · Moderate

Lower concern, traditional cast iron has no PFAS-prone coatings.

Verdict: BuyCast iron skillet with traditional oil seasoning poses minimal chemical hazard; no known defects or coatings that leach toxins.

Smithey's No. 10 is bare cast iron seasoned with oil, a PFAS-risk category inherently lower than nonstick cookware. The brand makes no PFAS claims and provides no third-party testing, but the material itself, pre-seasoned cast iron, has no known Teflon-family coating or water-repellent treatments that typically introduce forever…

The full breakdown

What it's made of and why it matters

Smithey No. 10 is solid cast iron with an applied oil-based seasoning layer, not an enamel or synthetic nonstick coating. Cast iron itself is inert under normal cooking conditions and does not degrade into the food. The seasoning is a polymerized oil layer that hardens through heat and repeated use, chemically distinct from applied enamel glazes or Teflon-type coating nonstick surfaces that carry known leaching risks.

The brand's record and disclosure

Smithey is a premium US cookware maker with a reputation for hand-finished cast iron and transparency about materials and sourcing. The company does not publicly disclose PFAS testing or certifications for its products, and maintains a largely silent stance on chemical safety beyond traditional cast iron practice. No recalls, contamination reports, or documented chemical safety incidents are on record for this product line.

How it compares in its category

Traditional cast iron skillets like this Smithey piece avoid the hazard profile of enameled cast iron (lead or cadmium in glazes), ceramic nonstick (coating degradation), and Teflon-type coating nonstick (fume risk above 500°F). Hand-seasoned cast iron is the simplest category design and carries the lowest chemical complexity in the cookware market, though it requires active maintenance.

If you buy it

Season and maintain regularly with food-grade oil to preserve the seasoning layer and prevent rust; avoid prolonged soaking or dishwasher use. Cast iron can leach small amounts of dietary iron, which is nutritionally beneficial for most people but should be monitored by those with iron-overload conditions. Do not heat empty above 500°F as seasoning can break down; typical stovetop and oven use poses no hazard. Replace only if the cooking surface becomes severely pitted or cracked.

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.”

Possible

Iron leaching into food

Cast iron naturally leaches trace iron during cooking, especially with acidic foods. This is generally nutritionally benign or beneficial for most consumers but should be considered by those with hemochromatosis or iron-overload disorders.

Possible

Seasoning degradation and rust

If seasoning is not maintained through regular oiling and use, bare cast iron can rust. Rust itself is not a direct toxin but indicates loss of the protective layer; worn or heavily oxidized cookware should be reseasoned or replaced.

None known

Lead or cadmium in historical cast iron

Vintage cast iron can contain lead in certain enameled coatings or from legacy smelting practices. Smithey is a modern manufacturer using contemporary foundry standards; no lead or cadmium contamination has been documented in their products.

None known

Coating applied to handle or exterior

Smithey cast iron skillets have uncoated handles and exteriors. No synthetic finishes, varnishes, or paint are applied to this product that could off-gas or degrade.

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 92% 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.
