Stargazer Cast Iron · Cast Iron Skillets
Stargazer Bare 12-Inch Cast Iron Skillet
Lower PFAS concern, bare cast iron has no synthetic coatings where forever chemicals typically hide.
Stargazer Bare Cast Iron is made from uncoated cast iron, which is not a typical PFAS-containing product category. Cast iron cookware poses no inherent PFAS risk because it relies on seasoning with oils or fats, not Teflon-family coating or water-resistant treatments.

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
The Stargazer Bare 12-inch skillet is raw cast iron with no enamel, ceramic, or non-stick coating. This means there are no factory-applied finishes that could degrade, leach, or release fumes at high heat. Cast iron itself is inert; the only chemical interaction occurs between food and the seasoning layer (usually oil-based) that the user builds over time. This design eliminates risks associated with coating breakdown but places full responsibility for food safety on proper seasoning and maintenance.
The brand's record and disclosure
Stargazer Cast Iron does not publicly disclose third-party testing, food-contact certifications (such as FDA compliance statements), or safety audits in readily available materials. The brand markets the product as a bare, user-seasoned skillet without emphasis on testing or standards. No major recalls or safety controversies are on public record for this brand or product line. The silent stance on PFAS and other safety certifications is typical of small cast iron producers but limits independent verification of claims.
How it compares in its category
Bare cast iron skillets like this one avoid the chemical hazards of enameled cast iron (lead in glazes, coating flaking) and non-stick variants (Teflon-type coating, PFOA, GenX). They are chemically simpler than most alternatives. However, they require user diligence to build a protective oil seasoning layer; improperly seasoned bare iron can leave microscopic iron particles in acidic foods and offers no barrier protection. Pre-seasoned or enameled options trade this maintenance burden for manufacturing-applied coatings whose long-term integrity depends on brand quality control.
If you buy it
Build a robust seasoning layer before first use (multiple thin coats of high-smoke-point oil, baked on). Do not cook acidic foods (citrus, tomato, vinegar) in under-seasoned iron; they can strip seasoning and leach iron into food. Avoid prolonged soaking; dry immediately after washing. Seasonings degrade with use and high-heat cooking, so re-season occasionally. Replace or restrip and reseason if surface shows rust, pitting, or buildup that won't clean off with normal care.
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 from bare metal
Improperly seasoned bare cast iron or prolonged contact with acidic foods can leach elemental iron into food. While iron is essential in small amounts, excessive intake is a documented health concern. Proper, well-maintained seasoning prevents this.
Bacterial/pathogen colonization if not dried
Unlike smooth non-stick or enamel surfaces, cast iron's porous microstructure can harbor bacteria if left wet or incompletely dried. Food poisoning risk is low if standard drying and storage practices are followed.
Oil degradation and smoke toxins from seasoning layer
The user-applied seasoning is polymerized oil, which can degrade at very high heat (above 500F sustained). Degraded seasoning may release carbonyls or other combustion byproducts. Use at moderate-to-high heat rather than extreme temperatures.
Lead or cadmium in cast iron ore (historical risk)
Modern cast iron production is regulated in developed countries to exclude leaded scrap. No testing data or recalls link Stargazer skillets to lead or cadmium contamination. This is a resolved category risk in contemporary products.
Aluminum leaching
Cast iron contains little to no aluminum; this hazard does not apply to bare iron skillets.
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.
