Le Creuset Rectangular Cake Tin, Is It Non-Toxic?
Lower concern, enameled cast iron is traditional non-Teflon-family coating cookware.
Le Creuset's rectangular cake tin is cast iron with a ceramic enamel glaze, not Teflon-type coating or Teflon-family coating nonstick. Enamel glazes don't typically require PFAS treatments.

Is Le Creuset Rectangular Cake Tin non-toxic? What it is made of
Le Creuset rectangular cake tins are enameled cast iron, a cast iron base topped with a vitreous enamel glaze (glass-like coating fused at high temperature). This construction avoids synthetic non-stick coatings (Teflon-type coating, PFOA) entirely. The enamel acts as a barrier between food and iron, preventing iron leaching under normal use. Enameled cast iron is one of the oldest and most chemically stable cookware designs available.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Enamel coating degradation and chipping
Iron leaching from exposed cast iron
If enamel coating chips and raw cast iron is exposed, particularly in acidic foods (tomato-based cakes or batters), iron may leach into food. Small amounts of dietary iron are beneficial, but excessive leaching from damaged cookware is undesirable.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lead
No recalls or documented migration incidents on record for Le Creuset enameled cookware. European manufacturing and ISO compliance make this unlikely, but brand does not publicly release test data.
Source, ATSDR ↗Teflon-type coating fume release (non-stick coatings)
Not applicable; enameled cast iron contains no Teflon-type coating or Teflon-family coating non-stick coating. This eliminates the primary thermal decomposition hazard of modern non-stick bakeware.
Ceramic or enamel off-gassing (VOCs)
Factory-cured enamel glaze does not off-gas under normal baking conditions. No volatile organic compound issues have been documented for Le Creuset enameled cookware during use.
How is this PFAS grade calculated?
The brand's record and disclosure
Le Creuset does not publicly disclose detailed enamel composition or third-party testing results, which is typical for premium cookware brands and not unusual in this segment. The brand has no established recalls for lead, cadmium, or other heavy metals in enameled cookware over decades of documented use. Le Creuset maintains ISO 9001 certification and manufactures primarily in France under European safety standards, including compliance with EU cookware regulations that limit lead and cadmium migration.
How it compares in its category
Enameled cast iron is a traditional, chemically inert choice compared to modern non-stick coatings (which carry Teflon-type coating fume risks at high heat) and aluminum or ceramic-coated steel (which can leach aluminum or degrade over time). Le Creuset's enamel is factory-applied and chip-resistant relative to budget competitors, though still subject to eventual surface wear. Pricing reflects this durability; it is higher than mass-market bakeware but comparable to other premium enameled cast iron lines.
If you buy it
Hand wash to preserve enamel; avoid sudden temperature changes and metal utensils that chip glaze. Use at typical cake baking temperatures (350-425F); enamel is stable well beyond this range. Inspect periodically for chips or cracks exposing raw cast iron underneath; if chipping occurs, the piece should be retired to avoid rust and iron rust particles in food. Enameled cast iron improves with age when cared for and will outlast most modern cookware.
