Smithey · Cast Iron Skillets

Smithey Ironware Company Cast Iron Skillet No. 12

A · Very low PFAS

Lower PFAS concern, cast iron is an inherently safe, non-coated cookware material.

Verdict: BuyCast iron is chemically inert with no known coating hazards; Smithey has solid reputation for quality and transparency on materials.

Smithey's No. 12 is solid cast iron seasoned with conventional vegetable oil, not synthetic nonstick coatings. Cast iron cookware has no known PFAS risk profile. The brand does not claim PFAS-free status, but it doesn't need to, the material itself poses negligible concern.

Why this grade

Category baseline

cookware is a category where PFAS exposure is more common.

Hurts the grade

Uncoated safe material

Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.

The full breakdown

What it's made of and why it matters

Smithey No. 12 is solid cast iron with a factory vegetable-oil seasoning layer. Cast iron itself is biologically inert and does not leach harmful chemicals into food under normal cooking conditions, even at high heat. The pre-applied seasoning is a thin polymerized oil layer that builds over time with use and creates a natural non-stick surface without synthetic coatings, polymers, or fluorinated chemicals.

The brand's record and disclosure

Smithey is a U.S.-based cookware manufacturer with a transparent business model and consistent focus on traditional cast-iron methods. The company does not claim third-party certifications but publishes production details and material sourcing on its website. No recalls, PFOA contamination reports, or coating-degradation complaints have been documented for Smithey cast iron products in public safety databases.

How it compares in its category

Cast iron skillets like this eliminate hazards present in non-stick (Teflon-type coating/PFOA) and ceramic-coated cookware, which carry heating risks and potential coating flaking. Smithey's hand-finished approach and heirloom design place it in the premium segment; it is more expensive than mass-produced cast iron but comparable in material safety to other bare or traditionally seasoned cast-iron brands. The main trade-off versus non-stick is slightly longer heating time and the need for re-seasoning maintenance.

If you buy it

Cure the skillet with oil and heat before first use per Smithey's instructions to strengthen the seasoning. Avoid prolonged soaking and use gentle hand-washing after cooking; dishwasher use will strip seasoning. Cast iron can be used at any stovetop temperature and oven heat without coating failure. Re-season annually or as needed if dark, smooth finish begins to appear dull or sticky food residue accumulates; the skillet will last decades and improve with age.

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

Unseasoned or poorly maintained cast iron can release small amounts of dissolved iron into acidic foods (tomato sauce, wine-based dishes). For most people this is nutritionally neutral or beneficial; those with hemochromatosis should limit cast-iron cookware. Smithey's pre-seasoning reduces this risk.

Possible

Thermal shock and fracture

Cast iron can crack if exposed to rapid temperature changes (e.g., a cold liquid poured into a hot skillet). This is a physical hazard, not a chemical one, but results in sharp edges and loss of structural integrity. Avoid thermal stress by allowing the pan to cool gradually.

Possible

Seasoning degradation over time

The vegetable-oil seasoning layer can wear away with aggressive scrubbing or dishwasher use, exposing bare iron. Once exposed, the pan requires re-seasoning; bare cast iron does not pose a safety risk but loses non-stick properties and is more prone to rust.

None known

Heavy-metal contamination in source ore

Cast iron from reputable manufacturers like Smithey is smelted from standard iron ore with no documented lead or cadmium accumulation. Smithey does not disclose specific ore sourcing, but no recalls or contamination reports exist for their products.

None known

Coating degradation and flaking (non-applicable)

Smithey skillets have no synthetic enamel, ceramic, or non-stick coating, so coating flaking is not a hazard. The seasoning is a natural polymer layer that bonds chemically to the iron surface and does not chip or peel in the manner of enameled cookware.

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.
