Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want bare carbon steel with no coatings of any kind and an explicit PFAS-free claim directly from the brand.
You are an experienced cook who already avoids acidic ingredients in your carbon steel and won't miss that cooking use case.
The welded iron handle — with no rivets to trap moisture and no oven temperature limit — is important to you.
You cook on induction and want a confirmed-compatible pan with professional French construction.
You want the largest cooking surface (12.5") with 3mm professional gauge in this carbon steel set
You cook large proteins or batch meals where surface area matters more than handle oven-ceiling
You want verified PFAS-free bare carbon steel with professional French construction
The main thing to know
In 2024, French food safety regulators documented iron and trace-metal migration exceeding EU safety limits when Matfer pans were tested under acidic cooking conditions. Matfer issued guidance to avoid acidic foods — a real restriction that rules out tomato sauces, wine braises, and citrus dishes.
No oven-safe temperature rating published — the stainless-steel-riveted handle implies limited oven use, but the exact ceiling is unconfirmed. Budget time for beeswax full-pan removal before first seasoning.
Skip this if you...
You regularly cook tomato sauces, wine reductions, citrus glazes, or other acidic dishes — the 2024 iron-leaching guidance applies to this pan.
You want to know the pan's gauge thickness before buying — Matfer does not disclose this spec anywhere.
You want a carbon steel pan where first-use prep is clearly explained — the factory coating type is unspecified.
Oven finishing at high temperature is important — the Element (400°F confirmed) or Blue (500°F) are safer choices if you regularly finish proteins in the oven
You are new to carbon steel — the beeswax setup and larger mass make this a better choice for experienced users
You want the most usability-optimized de Buyer — the Blue at $70 has the welded handle and 500°F oven rating for $40 less
