Frying Pan Company Sued for Claiming Temperatures That Rival the Sun (theverge.com) 124

Can you heat up a pan to 30,000 degrees Fahrenheit? That's the burning question at the center of this proposed class action lawsuit, which claims the advertising for SharkNinja's nonstick cookware violates the laws of physics and thermodynamics. From a report: While SharkNinja is the company best known for its Shark robovacs and Ninja kitchen gadget, this lawsuit takes issue with the Ninja NeverStick Premium Cookware collection, a line of pots and pans it advertises as having superior nonsticking and nonflaking qualities thanks to its manufacturing process.

Instead of making its pans at a measly 900-degree temperature that other brands use, SharkNinja says it heats up the cookware to a maximum of 30,000 degrees Fahrenheit. That process, according to SharkNinja, fuses "plasma ceramic particles" to the surface of the pan, "creating a super-hard, textured surface that interlocks with our exclusive coating for a superior bond." But Patricia Brown, the person who filed this lawsuit, isn't buying it. As cited in Brown's lawsuit, NASA recently said the "surface of the Sun is a blisteringly hot 10,340 degrees Fahrenheit," meaning SharkNinja's manufacturing process reaches about three times that temperature.

    Seriously, no matter what the brand or make if it's sold as "nonstick" chances are eventually it will start to be just a "stick" pan and really, they are of limited use anyway, at least in my opinion.

    The main thing I have a nonstick for is eggs, especially omelets and for that i tend to find the el-cheapo straight up teflon coated pans work great and then just get a new one when it eventually stops working which they will even when I baby them; no high heat, no metal tools, no dishwasher, no abrasives.

    Everything else can be accomplished with decent stainless pans or seasoned cast iron or an enameled cast like a Le Cruset, all of which can be very nonstick with proper techniques.

        The bonus part of this non-stick transition is that all of that 'whatever it is' is going into your body.

        So I heard. The argument, though, is that if you use a traditional pan then you get a whole load of really interesting nasty carbon chemistry and that goes into your body instead and is likely to be worse on average. Any actual evidence on doses would be nice, but then again why spoil a nice internet "discussion" with evidence.

            You can, but since it's less likely to stick when you move it, you're more likely to burn it less. It's all meant to be a trade off, which means you should make the choice based on actual data, which seems to be lacking. I did a little research trying to work out if you can restore a non stick frying pan and realised that a) the risk from a scratch is probably overrated and b) none of the restoring chemicals seems to be officially tested and they seem to be complete con jobs.

          At any rate, my first chance to use them will be next weekend. I'll post a review once I have enough experience with them.

          • Coating the outside of the pants with dish soap and allowing it to dry will help reduce but not eliminate the blackening on the outside of the pans. That washes off, of course, the first time you scrub the pans. The biggest thing is to cook over coals instead of flame.

      While I can appreciate your well-seasoned argument here for alternative materials, let's not overlook the obvious here. Liars are still lying. Marketing and the bullshit pimps that work in that industry, are overrated. And I hope this lawsuit hits like Mike Tyson.

      Lying is something we need to actually appreciate punishing again. Otherwise consumers won't even know where to find truth anymore. Soon they won't even remember why they should value it.

    • Anything with a coating WILL eventually flake chip or wear off. Cast iron and stainless doesn't have this problem, Plain aluminum gives everything flavor plus there is that question of health effects from ingesting aluminum, but I do use hard anodized aluminum for my pizza pan and a chef's style pan that I often also use in the oven. Glass casseroles are also still a thing.

      All thin lightweight pans are hard to control heat and burn, which causes the sticking, too easily. Unless you are frail get cast iro

      The main thing I have a nonstick for is eggs

      I make eggs for breakfast multiple times a week and the day I switched to cast iron was an eye opener. Properly seasoned, it cleans up with sponge and water, no detergent, the eggs taste better, and it’s a whole lot easier to judge temperature, cooking consistency, etc.

      I donated all my nonstick cookware to Goodwill once I discovered cast iron. You mention it, clearly aware of it, I am surprised you don’t use it for your eggs. What is your rationale for that?

      • by narcc ( 412956 )

        You're not wrong, but cast iron takes discipline and effort to maintain. I can see people thinking they're not worth the trouble, particularly if they don't cook a lot or they've "ruined" a cast iron pan in the past.

        It's a lot easier to "season" a stainless pan every once in a while and as long as you let it heat up before cooking, it'll consistently work better than a 3-month-old non-stick pan, which I'm guessing translates to "as good as non-stick" for most of us.

        • by Shakrai ( 717556 )

          Discipline to maintain yes, effort, no, IMHO. I find handwashing eggs off a "nonstick" to be a very tedious undertaking and none of the quality ones are dishwasher safe. My cast iron cleans with water, a few wipes of a sponge, paper towel to dry, and occasional re-seasoning with oil. Two minutes or less.

      • by ls671 ( 1122017 )

        Indeed, no real chef uses non-stick. Use cast iron or even cheap thin metal pans, they are perfect. Before using them, just use salt and a piece of paper towel to scrub the dry pan, dump the salt then, put in some oil then a tiny tiny amount of salt with your finger evenly spread across the surface which will act as "ball bearings" preventing sticking. Nothing will stick, eggs, crepes suzette, etc. That's what real French chefs do!

        The heat never goes above medium-low and the omelet slides out so its easy to fold out of the pan. If Jacques Pepin is fine using a nonstick for eggs why should i be snoot about

    • Except the oldest and still best of nonstick pans: cast iron. With a non-stick coating that will self-repair from most damage, and is easily manually repaired in the case of more serious damage.

    • Everything else can be accomplished with decent stainless pans or seasoned cast iron or an enameled cast like a Le Cruset, all of which can be very nonstick with proper techniques.

      The proper technique to get an omelette not to stick is to use lots and lots of oil.

      Watch a professional chef sometime. It's edifying how they don't stint on oil.

      (number two tip is to put no scratches into the pan).

    • by labnet ( 457441 )

      Stainless steel works better for eggs.
      Thin layer of oil (we use macedamia) and no sticking but the eggs have to beaten. Unbeaten eggs will stick.
      Stainless pan on an induction takes 30secs to heat and virtually no cleanup and will last decades.
      Much easier to take care of than cast iron.

      It's plasma spray coating. For some ceramics, you do actually need a 30,000 degree plasma arc to ensure the ceramic powder is fully melted in the short time it's actually in the plasma before being sprayed onto the metal where it cools and bonds.

      It's not a new or spectacular process. It's a marketing idiot who confused the temperature of the plasma for the temperature the pan would be subjected to. Whether it's ignorance or deceit is impossible to tell from the story.

      • by cirby ( 2599 ) on Friday October 20, 2023 @05:25PM (#63940605)

        Technically, it probably is being subjected to that temperature for a small fraction of a second.

        The confusion here is "temperature vs heat." You can have incredibly high temperatures in things like plasma, but the moment a thin plasma touches a solid surface, it transfers that very small amount of heat to the metal, without any real damage.

        If you wave your hand quickly through a candle flame, for a fraction of a second you're subjecting your skin to 2500 F or so - without harm. If you move a stick through that same flame at a slower speed, you'll coat the stick with a thin layer of soot - without catching the stick on fire.

      Really? Is it? And what proof do you have? No, I mean actual proof. What physical evidence can you bring forth that the sun actually exceeds a manufacturers claims?

    • Seems to me they aren't claiming they heat the whole pan to 30,000 degrees. I cook meat on my konro grill to 130F, even though the heat source is 1000F. If it's doing what they claim, it's probably only the first few atoms that are involved.

      The actual claims-
      "With a max manufacturing temperature of 30,000F, our cookware won't rapidly lose nonstick like traditional pans made at 900F can."
      "Super-heated at 30,000F, plasma ceramic particles are fused to the surface of the pan, creating a super-hard, textured surface that interlocks with our exclusive coating for a superior bond. "

      standard plasma coating stuff.

      • I was going to say, it's pretty clear that they are talking about the temperature of the plasma, and that temperature is not unusual for plasma. The real problem is that the temperature of the plasma says nothing about how well the coating will perform, so they're not really giving us useful data about the quality of the product.

    If you know the definition of the temperature then you would also know that billiard balls moving randomly on pool table have temperature way higher than the sun's surface if you consider each particle as independent. The definition of temperature is average random KE per particle and you can defined any object as particle.

    Going to more down to earth, you can create temperature higher than sun in many system. It won't achieve the same energy density though (without melting immediately). Plasmas in experimental fusion reactors go to 100 million degrees.

    Even if the claim of 30000 degree is false, I don't see how this lawsuit is valid. For it to be valid, you have to show harm done to you as well. If you say that because you read 30000 degree and presumed it to be better than the competitors and it is not then only you can win the lawsuit. So good luck.

    • For it to be valid, you have to show harm done to you as well.

      The very basis of marketing effectiveness means that false claims create harm. That harm bar is a pathetically low bar to cross when it comes to marketing claims.

    This (really old) article from The Washington Post describes a ceramic coating process that sounds close to what SharkNinja advertises:

            The newest high-tech wrinkle in nonstickiness is a coating called ceramic-titanium, developed in Denmark and used on Scanpan cookware. A mixture of titanium and a ceramic, so hot (30,000 degrees) that their atoms are broken down into a cloud of charged particles (Techspeak: a plasma), is fired at supersonic speed at the surface of an aluminum pan, where it anchors itself right into the metal, making an extremely hard, unscratchable surface.

  • What's the actual claim about? It can't be about only the temperature at which the pans are created. This is just ridiculous, the legal system is already overworked with bogus claims. How much does she hope she wins? These type of claims should never pay out more then the cost of the product itself, which of course in this case is a fraction of what the actual lawsuit costs.
  • How can my fellow pedantic artists here not call out this atrocity that goes against the laws of thermodynamics?!?!

    In what world is 30k degrees = 3x 10k degrees?

    What's next? 100 degrees is twice as hot as 50 degrees? 150 degrees isn't even twice as hot as 100 degrees?

    Either use kelvin or consider making use of the particle frequencies of variation between temperatures if you want to do a "three times" type deal!

  • Processes exist that can get things up to extreme temperatures, and as started in at least one process the coating is converted to a plasma, so it can bind with the surface. It's also worth noting that the surface of the sun is not the “hot” part of the sun, which the average grade 6 student would be aware of.

    The theoretical temperature at the core is ~1.5 x 10^7 C, or 15 Million degrees Celsius. To put it another way, the core is ~2620x hotter than the surface (5730 C), or the core is ~900

For a very long time we've all seemed to accept the soft deception that occurs in advertising, primarily because meaningless statements and ambiguous claims ar

  • Presumably the marketing claim is just slightly confused language, because the pan is subjected to some plasma in the process, and that actually is hotter than the surface of the sun.
