Old Mountain · Cast Iron Skillets
Old Mountain Skillet
Lower-concern cast iron skillet; no PFAS risk inherent to material.
Old Mountain skillets are traditional cast iron cookware with no synthetic nonstick coating or Teflon-family coating treatment. Cast iron does not require or typically use PFAS-based finishes, making this product category a lower-concern choice for PFAS exposure.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
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
Old Mountain skillets are cast iron, a ferrous metal alloy typically containing iron, carbon, and trace manganese or silicon. Cast iron has no synthetic polymer coating or non-stick treatment, eliminating risks from Teflon-type coating fume release or coating degradation common in modern non-stick cookware. The bare metal surface can leach small amounts of iron into acidic foods, which is nutritionally benign and sometimes desirable for iron-deficient users.
The brand's record and disclosure
Old Mountain is a legacy American cast iron manufacturer with no documented recalls, safety violations, or public health controversies in available records. The brand does not publish detailed material certifications or third-party testing results, which is typical for the cast iron category and reflects industry convention rather than a red flag. No documented PFAS statements or environmental claims exist, consistent with the product's material class.
How it compares in its category
Traditional cast iron skillets like Old Mountain occupy the safest tier of cookware: they require no protective coatings and generate no fume risk at any household temperature. They are chemically more inert than enameled cast iron (which can have lead or cadmium in glaze pigments) and far safer than modern non-stick alternatives that rely on Teflon-type coating or ceramic coatings. The trade-off is higher maintenance and longer seasoning time compared to pre-seasoned or non-stick competitors.
If you buy it
Season and maintain the skillet regularly with oil to prevent rust and build a natural non-stick layer; avoid prolonged soaking and dry immediately after washing. Cast iron can safely withstand stovetop, oven, and campfire heat without coating failure. Replace only if structural damage (deep cracks, large rust pits) occurs; the bare metal itself does not degrade chemically. Avoid storing acidic foods (tomato sauce, vinegar, citrus) in the skillet for extended periods to minimize iron leaching.
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.”
Iron leaching into acidic foods
Bare cast iron can release small amounts of iron when in contact with acidic foods (pH below 4.5). For most users this is negligible or beneficial; only those with iron-overload disorders (hemochromatosis) should minimize prolonged contact with acidic foods in cast iron.
Rust formation if poorly maintained
Unlike enameled or non-stick cookware, uncoated cast iron will rust if not dried and seasoned regularly. Surface rust is not a food safety hazard but indicates loss of protective oil layer; deep rust pitting can reduce the skillet's structural integrity and aesthetic appeal.
Lead or cadmium in glaze (if enameled variant)
Standard Old Mountain cast iron is bare, uncoated metal and carries no glaze hazard. If purchasing an enameled Old Mountain skillet (less common), verify the enamel supplier; the brand has no known recalls or safety advisories for enameled products.
Manufacturing residue or machining oils
New cast iron skillets may retain light factory oil or machining residue; this is removed by the initial seasoning and first use. No documented contamination or toxic residue issues have been reported for Old Mountain products.
Thermal shock or handle durability
Cast iron is brittle and can crack under rapid temperature changes, but this is a structural risk rather than a chemical hazard. Old Mountain skillets have a long service history; no widespread handle fracture or detachment recalls are on record.
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.
