Which is just about “red-hot” temperature, so it’s quite plausible that aluminum in contact with a stove burner might melt. That’s far from the truth. I did not see signs of melted metal though. Burning aluminum would be much more hazardous than burning fat. Is this true? A bigger fire can end up damaging various parts of your microwave and essentially making it unsafe to use. Save 52% when you subscribe to BBC Science Focus Magazine. 1 decade ago. If we were able to dig through the Earth, at what point would you stop digging down and start digging up? Incompatibilities and reactivities listed are: Strong oxidizers & acids, halogenated hydrocarbons. That said, aluminium in a glowing hot fire will decay slowly, so too the hottest range top or oven elements that are basically steel glowing red hot are going to decay the aluminium slowly. If it doesn't absorb the heat then it won't overheat and catch on fire. Subscribe to BBC Focus magazine for fascinating new Q&As every month and follow @sciencefocusQA on Twitter for your daily dose of fun science facts. Already have an account with us? They stopped making warship superstructures from aluminum because it was learned the hard way that aluminum WILL BURN if hit by an exocet missile or the equivalent. I’ve also used foil in an oven under pans, over turkeys, and as a baking sheet for cookies and have never had an incident of failure of the aluminum. It catches on so quick. Save 52% when you subscribe to BBC Science Focus Magazine. The grease from the steak will ignite, causing the foil to melt. 1 decade ago. The temperature at which aluminum metal (as opposed to powder) will combust, if there is one, is well above anything available in households. I’d hope your element, assuming a contact electric element, gets a whole lot hotter than 212F. I’m pretty sure I recall an incident where I put aluminum foil in the microwave and it caught on fire. It never caught fire. :smack: Anecdotally, I’ve used aluminum foil on my drip pans for years and have never had an incident of fire. Or did I hallucinate? Recently someone told me not to cover the stove drip pans with aluminum foil, because it may catch on fire. That’s because the sun’s rays bathe the Earth in a constant flow of thermal energy spread over each square metre. Fishbowls, jam-jars and even glass door-knobs have been implicated in focusing the sun’s rays sufficiently to cause smouldering, followed by a full-scale blaze. In the case of “tinfoil” – really “aluminum foil” – you may get a high current flowing because of the microwave energy & maybe get some arcing, but if there is no fuel, such as … Why doesn’t the Sun fuse all its hydrogen at once and explode like an H-bomb? Our was in the broiler. What is the ratio of males to females on the planet? Magnifying glasses do this very effectively, refracting the rays and bringing them to a tight focus. I have an electric stove with over the top coil heating elements (2600watt 8") that can be pulled out to clean the drip pans. Aluminium pans that are purely aluminium will not be ignited by range tops, broilers, baking ovens, toasting ovens…. Unlike pure quality aluminum which is highly reactive (used mainly in lab demos). 0 0. Earlier this year, London Fire Brigade said that 125 fires have been triggered by the sun’s rays over the last five years – and warned that the risk exists during the winter as well as summer. It was arcing, not burning (Which I’ll define as a self-sustaining process), It would seem to me that if you didn’t change the foil when the gunk started to collect, then you may ignite the gunk but that doesn’t have anything to do with using foil.

If you’re form-fitting the foil to the pans and are making sure the foil can’t touch the contacts of the element, you shouldn’t have any problems. Aluminium pans that are empty can catch on fire. Here is the material safety data sheet on “Consumer/Foodservice use aluminum foil” from Alcoa (Warning: PDF).

Could the ocean ever become too salty for life to exist? In some cases, there have even been microwave fires that catch on other parts of the kitchen and end up causing major house fires. Fishbowls, jam-jars and even glass door-knobs have been implicated in focusing the sun’s rays sufficiently to cause smouldering, followed by a full-scale blaze. I never could find any on which the chrome finish was worth a hoot. Look out for your Lunchtime Genius newsletter in your inbox soon. That may be what “it will catch on fire” is intended to mean, since the effect is much the same. The reason I used the foil was to keep the pans from rusting out and getting ugly so fast. The conditions are that the stove is clean, so is the aluminum and that the heating element reaches a max of about 152 to 212 degrees Fahrenheit. Powered by Discourse, best viewed with JavaScript enabled, “Consumer/Foodservice use aluminum foil” from Alcoa. Why is it colder at the top of a mountain, if you’re closer to the Sun? Lv 7. Thanks! You could also argue that, being such a good conductor, the heat from the drippings is quickly reduced. I don’t know how hot they get, exactly, but it’s enough to light a cigarette, so it has to be somewhere near 450F (as standard paper ignites at 451, from the name of the book Fahrenheit 451 by Ray Bradbury. I kept aluminum foil on stove drip pans for years. The aluminum foil is standard commercially available foil. Since aluminum foil can potentially cause problems, it … I got those temperatures from GE online on a “heating element” replacement manual. FWIW, NIOSH states the following about Alumnium Metal: Melts @ 1220°F, no flash or ignition point listed. Because it is metal and it's burning point is way higher than an ovens temperature can ... Tin Foil. Actually , the effect would be quite different. Hi all: Quoth danceswithcats of twelve years ago: FWIW, NIOSH states the following about Alumnium Metal: Melts @ 1220°F,…. Nonetheless, no household oven should ever be capable of generating enough heat to ignite aluminum. However, aluminum is highly conductive of heat, and so the drippings that inevitably collect in the drip pan may be heated to the combustion point by the aluminum lining conducting heat from the burner to them. I wash mine with the dishes every time I cook. Nope Im not planning on getting a set of reflectors, just wanted to know whether it can catch on fire by it-self. It is possible for aluminum pie plates to catch on fire outside in the sun if they become extremely hot or receive focused sunlight. I was told tin foil has a dark and shiny side. Be careful, No. Solusia. As others have mentioned, other gunk (fat, usually) will catch fire in drip pans if allowed to accumulate, but this will happen with or without covering the pans in foil.
