The Frying Pan Without the Coating

The Problem

PFAS do not break down in the human body. They accumulate in blood, organs, and breast milk. The carbon-fluorine bond that makes non-stick coatings slippery is the same bond that makes them permanent inside you. Over 12,000 PFAS compounds exist. Regulators evaluate them one at a time. The property that makes them all dangerous is shared by every single one.

Two pathways deliver them into your food every time you cook. The first: dissolved fluorinated chemicals migrating from coating to food at simmering temperatures. The second: solid PTFE microparticles physically shedding from the surface — thousands per cooking session, each carrying fluorinated compounds into what you eat.

The label says "PFOA-free." The replacement compound has a safety threshold 6.7 times stricter — regulators consider it more dangerous at lower concentrations. PTFE coats virtually every non-stick pan sold. Ceramic coatings were marketed as the safe alternative, but they degrade in one to three years with undisclosed proprietary formulations. The "safe substitute" is another version of the same problem. The pan degrades. You replace it every three to five years. The cycle continues.

The Gap

Nitriding — heating iron in a nitrogen atmosphere to harden the surface — has been used in aerospace, automotive, and medical applications for over a century. The metallurgy is settled. No manufacturer has built a nitrided iron skillet to the standard this problem demands: single-material construction, full process transparency, zero synthetic components, and published migration testing.

What Should Exist

A frying pan where the cooking surface is the pan itself — no coating to shed, no compounds to migrate.

• Nitrided iron construction — nitrogen diffused into the metal, forming iron nitrides. No polymer. No fluorinated anything.
• Single material throughout — no aluminium core, no composite layers, no silicone grips. Iron and nitrogen only.
• Full process disclosure — nitriding method, iron source, manufacturing location. Every material stated and verifiable.
• Published migration testing — third-party evidence, not marketing claims.
• Forever recyclable — iron is the most recycled material on Earth. Nitrogen escapes as harmless gas during melting. No contamination of the recycling stream.

The Honest Position

This is a premium product. Single-material nitrided iron costs more than a coated pan designed to last three years.

It will be heavier than aluminium. It will not be non-stick like new PTFE on day one — it needs seasoning to reach its stride. Long-simmered acidic sauces are still better in stainless steel or enamel. For everything else, this is the pan.

The Investigation: The Safe Substitute — what "PFOA-free" actually means, what replaced it, and why the replacement may be worse.
