  Remember not to leave your non-stick pan on the stovetop for too long folks and keep cockies out of the kitchen (I rather scrab my yes-stick one and skip munching on PTFE flakes):

  Pyrolysis of PTFE is detectable at 200 °C (392 °F), and it evolves several fluorocarbon gases and a sublimate. An animal study conducted in 1955 concluded that it is unlikely that these products would be generated in amounts significant to health at temperatures below 250 °C (482 °F).

  While PTFE is stable and nontoxic at lower temperatures, it begins to deteriorate after the temperature of cookware reaches about 260 °C (500 °F), and decomposes above 350 °C (662 °F).[52] The degradation by-products can be lethal to birds,[53] and can cause flu-like symptoms[54] in humans—see polymer fume fever. Meat is usually fried between 204 and 232 °C (399 and 450 °F), and most oils start to smoke before a temperature of 260 °C (500 °F) is reached, but there are at least two cooking oils (refined safflower oil at 265 °C (510 °F) and avocado oil at 271 °C (520 °F)) that have a higher smoke point.

    Yep, I know someone who's parakeets died when he put a Tefal pan on the fire.

      Parakeets would face the same fate in most fired pans…

    The study seems outdated in 1955, would the non stick material be improved over the 60 years?

      Fair point, found more studies, quite an interesting page, here is well-explained and more recent research:

      In a recent PTFE rat toxicity study, Dr. Carl Johnston et al. found that neither the ultrafine particles or the gases produced by PTFE are toxic by themselves, but the two together are extremely toxic together [15]. The authors suggest the particles are acting as carriers for absorbed gas particles, allowing the gas particles to travel to the lower respiratory tract and cause severe damage. Alternatively, the particles could be generating toxic reactive groups on their surfaces. Also, the size of the particles matters. The most toxic particles are called ultrafine and are 16 nanometers in diameter. If the particles are able to coagulate and form larger particles, greater than 100 nm, they are not as acutely toxic to rats.
      [15] Johnston, CJ., Finkelstein, JN., Mercer, P., Corson, N., Gelein, R and Oberdorster, G. 2000. Pulmonary effects induced by ultrafine PTFE particles. Toxicol Appl Pharmacol 168(3): 208-15.

      And this should be put on the label really (forgot pan on the stove - you ded):

      Studies show that thermal degradation of Teflon leads to the slow breakdown of the fluorinated polymer and the generation of a litany of toxic fumes including TFE (tetrafluoroethylene), HFP (hexafluoropropene), OFCB (octafluorocyclobutane), PFIB (perfluoroisobutane), carbonyl fluoride, CF4 (carbon tetrafluoride), TFA (trifluoroacetic acid), trifluoroacetic acid fluoride, perfluorobutane, SiF4 (silicon tetrafluoride), HF (hydrofluoric acid), and particulate matter. At least four of these gases are extremely toxic - PFIB, which is a chemical warfare agent 10 times more toxic than phosgene (COCl2, a chemical warfare agent used during World Wars I and II), carbonyl fluoride (COF2 which is the fluorine analog of phosgene), MFA (monofluoroacetic acid) which can kill people at low doses, and HF, a highly corrosive gas.

      They've gotten better, but remember birds have extremely sensitive lungs (hence the canary in the coal mine). In general, so long as you're not silly with your non-stick pans (ie you don't leave empty pans unattended on the fire) both you and your birds will not experience any effects.

  Just wondering if anyone else thinks the title is a little deceiving?

  C0mbat on 27/03/2018 - 22:13

  I'm confused. Is it $69 or $139? Either way, I'm also confused why you would want this complicated and messy looking thing vs just a normal grill pan?

    Assume $69.95 when you apply the code provided.

    If you ever been to a Korean BBQ restaurant you will understand the design.

  Most definitely its for KOREAN BBQ.
