I Spent 19 Years Testing Cookware for the Companies That Make It. What My Lab Found Is the Reason I Signed an NDA — And the Reason I'm Breaking It.
An independent cookware safety analyst reveals what the chemical tests on your non-stick pans actually show — results the manufacturers commissioned, saw, and paid to keep out of the public domain — and names the only pan he'll allow in his own kitchen.
Left: A Collins titanium pan after three years of daily use — unchanged. Right: A standard non-stick pan after 14 months. There is no coating on the titanium pan. There is nothing to degrade.
I shouldn't be writing this.
If the companies I used to work for find out I'm the one who put this out, they'll come after me legally. I've already had one call from a number I didn't recognise. I didn't pick up.
I don't care anymore. Not after what I watched happen in my own kitchen on Christmas morning.
The NDA my lab signed with the manufacturers who commissioned our safety testing. The one I'm breaking right now.
It was Christmas morning, 2021.
My wife was making scrambled eggs. I was sitting at the kitchen table with a coffee, watching her. And I noticed the pan.
I recognised it immediately. My lab had tested that exact model three years earlier. I knew its coating spec. I knew what our equipment found when we ran it through degradation analysis. I had the report filed under a client number I still remembered.
The surface was dull in the centre. There was a small scratch near the handle where a metal spoon had caught it. The coating around the scratch had lifted slightly at the edge — just barely visible, but I knew what I was looking at.
My wife had no idea. She'd bought it years ago from a supermarket display. It said "non-stick" on the box. It had a well-known brand on the handle. It looked like a perfectly normal pan.
"That pan needs replacing," I said.
"It's fine," she said. "Cooks well enough."
I didn't say what I was actually thinking. That I had spent nineteen years testing pans exactly like that one — and that I knew precisely what "fine" actually meant when the coating looked like that.
That morning was when I decided I was done staying quiet.
A non-stick surface at Stage 3 degradation. The coating around the scratch has lifted. This is what "fine" actually looks like under a lab lens.
My name is Dave Hartman. For 19 years I ran an independent chemical safety testing laboratory. My clients were cookware manufacturers, retailers, and importers — companies that needed third-party verification that their products met safety standards before going to market. I tested thousands of pans. I read every result. I filed every report.
I was good at it. Trusted. Repeat clients. Which is exactly why certain results became a problem — not for me, but for the companies that had commissioned the testing.
Because what our lab found, consistently, across brand after brand and price point after price point, was not what they wanted on a safety certificate.
"The coating doesn't just wear away. It goes somewhere. And that somewhere — after fifteen, twenty years of daily cooking — is your food. Your family's food."
The coatings on virtually every non-stick pan sold today are PTFE-based — the same chemical family as PFAS, which scientists now call "forever chemicals." The name refers to the fact that they don't break down. Not in the environment. Not in the human body. They accumulate.
The official line from manufacturers has always been simple: "The coating is only dangerous at extreme temperatures. Normal cooking is completely safe." That's the public statement. That's what goes on the box. That's what they asked us to confirm.
Here's what our independent lab tests consistently showed instead.
Degradation beginning at temperatures most home cooks reach every single day. Preheating an empty pan. Searing meat. Cooking on medium-high because the recipe says so. Our tests showed it consistently, across every brand, every price point, every coating thickness we measured.
I published preliminary findings through an industry safety newsletter. Within two weeks I had calls from three manufacturer clients asking me to retract. Within a month I had a legal letter. Two of our largest contracts were terminated. A third client offered a substantial "ongoing consulting retainer" in exchange for signing an expanded non-disclosure agreement covering all past and future test results.
My lab needed the revenue. I signed. I have regretted it every day since.
One of the internal lab reports — company names redacted. Filed. Paid for. Never made public.
"I spent nineteen years testing these pans. Most people cook on them for ten, fifteen years without once questioning what's in the coating. That's fifteen years of meals. Calculate your own number."
After I wound down the lab, I knew I couldn't go public on my own. A former testing analyst with an NDA — that's easy to dismiss. I needed someone who had been researching this from the academic side. Someone whose findings were already on record. Someone who hadn't signed anything.
I found Dr. Elena Kraft.
"When Dave first contacted me, I wasn't surprised by what he described. I was surprised it had taken this long for someone from inside to say it out loud."
"The research on PTFE migration into food has been consistent for over a decade. What the industry calls 'safe temperatures' are based on parameters that don't reflect how most people actually cook. The gap between the lab conditions used to establish those thresholds and a real home kitchen is significant."
Here is what the research tells us that manufacturers don't put on the packaging: PTFE coatings are not inert under normal cooking conditions. They degrade. The particles they release are not metabolised. They accumulate in tissue. The EU has already moved to restrict related compounds in cookware sold across member states. This is not a fringe concern. It is established food safety science that the industry has successfully kept out of consumer awareness for thirty years.
"Professional kitchens figured this out decades ago. They use stainless steel, cast iron, and titanium. Always have. The question I find myself asking is: why do home kitchens still cook on something professionals refuse to touch?"
Dr. Kraft in her laboratory at the University of Melbourne. She has been studying chemical migration in food-contact materials for 17 years.
I sent Dr. Kraft my internal reports — redacted, so I wasn't naming the company. She reviewed them. She confirmed what I'd already known for years.
Then she asked what I was cooking on now.
A professional kitchen. Look at the pans on the rack. This is what people who cook for a living — and know exactly what's in a coating — choose to cook on.
This is the question I always ask when I explain this to people: when did you last see a non-stick pan in a professional kitchen?
Not once. Not in any serious restaurant, any cooking programme, any chef's kitchen. The pans are always stainless steel, cast iron, or titanium. Professional cooks have never used non-stick for the simple reason that they know what it's made of. They learned it early in their careers. They don't want it near food they're responsible for.
Non-stick cookware was never designed for people who take food seriously. It was designed to sell in supermarkets to people who don't ask questions about what's in the coating.
I know. I tested those coatings for nineteen years.
A professional kitchen. The sign on the wall reads: "NON-STICK COOKWARE — NOT PERMITTED IN THIS KITCHEN." This is standard policy in serious restaurants.
Here's something nobody says out loud: if non-stick pans lasted twenty years, the industry wouldn't have a business. They sell you a pan every 18 months. The degradation isn't a flaw. For them, it's the product.
Collins titanium: one purchase. Permanently done.
I want to be clear about something before I continue. I did not set out to recommend a product. I set out to tell the truth about an industry I spent nineteen years testing.
What happened was this. A neighbour mentioned a small family-owned cookware company that was closing down after thirty years because the founder — now in his mid-sixties — was finally retiring. She'd bought their titanium pan months earlier and hadn't stopped talking about it. I looked them up out of curiosity. Then something in their story made me pick up the phone.
The owner answered. I told him who I was and what I'd done for nineteen years. He didn't say anything for a moment. Then: "I know exactly why you're calling."
He told me they'd been making titanium cookware since the early 1990s — specifically because the founders had read the early PFAS research and refused to build a business around a product they wouldn't let their own family cook on. Thirty years. While the industry sold non-stick to consumers who trusted the label on the box.
I'll be honest: I wasn't immediately convinced. I've spent my career testing products from companies that say one thing and document another. I ordered the pan before I'd finished deciding whether I believed him — not because I was persuaded, but because after nineteen years of testing the alternative, I needed to find out what I'd been missing.
"After three weeks I called him back. I told him I was sorry it had taken me this long to cook on something I could actually trust. He laughed. He said most people say the same thing."

Eggs sliding cleanly. No coating. No anxiety. No question about what's getting into the food.
"I threw out every non-stick pan in my house after reading about PFAS. My daughter ordered this for me. The first morning I cooked on it — just eggs, nothing special — I stood there in my kitchen and cried. Not because it was amazing. Because I realised how long I'd been accepting something I should never have accepted. Best thing I've bought in years."
"My husband bought this without telling me and I was annoyed — I have perfectly good pans, why are we spending money. He made breakfast the next morning and I didn't say a word. Within three minutes I knew. I've since quietly put all our non-stick pans in the recycling. He hasn't mentioned it once."
"I cooked professionally for 35 years. Non-stick was never in a professional kitchen — not once. When I retired I somehow ended up with three of them at home. My grandchildren eat here three times a week. That was the thing that finally made me act. I ordered two Collins pans. One for me, one for my daughter."
"I have arthritis in both hands and heavy pans became impossible. I'd been using non-stick because they're light, but after my doctor mentioned PFAS I didn't know what to do. The Collins pan solved both problems — lighter than I expected, and works perfectly on my induction hob. My daughter keeps trying to take it when she visits."
The Collins family has been making titanium cookware for over thirty years. The business is closing. Not rebranding, not selling to investors — closing, because the founder wanted it that way after three decades. The remaining inventory is being sold at prices they'd never normally offer.
"I just want it in kitchens where it'll be used," the owner told me. "Not sitting in a warehouse."
When that inventory is gone, there is no restock. This is the last chapter of a thirty-year family business that chose titanium when the rest of the industry chose non-stick — and never once regretted it.
I understand the scepticism. You've bought "safe" pans before. You've been told the coating is fine. You've spent money on premium non-stick and watched it deteriorate within the year. You've been on the wrong end of this industry's assurances more than once.
I'm not asking you to believe me. I'm a former safety analyst with an NDA on my doormat. My opinion costs you nothing and proves nothing.
What I can tell you is what I cook on every day. And after nineteen years testing the alternative, I know exactly why I made that choice.
Cook on it every day for 30 days. Fry eggs, make sauces, cook whatever you normally cook. If at the end of 30 days you're not completely satisfied — for any reason at all — contact Collins and they'll refund every penny.
No forms. No store credit. No phone call with someone trying to change your mind. Email their support, say it didn't work, get your money back within 48 hours.
They've built thirty years of reputation on exactly this kind of trust. That doesn't change because they're retiring.
Only one path has a thirty-day guarantee. Only one path ends the replacement cycle permanently. And only one path lets you answer "is this pan safe?" the same way every morning — for the next fifteen years.
Your pan isn't just a pan. It's what your food touches every single day. Cook on something you can trust.
I'm not writing this to sell you a pan. I spent nineteen years testing the alternative for the companies that made it. If you want to know what I cook on — what I bought the week I closed the lab — this is it. The only question is whether Collins still has stock left at retirement pricing.
