    Default Is a Coffee Can Pot Safe to Eat/Drink Out Of?

    I'm thinking of saving some money and just using a coffee can as my cook pot. Does anyone have any experience with this, good or bad? And does anyone know any reason why it might not be safe? I know I have to choose a can that doesn't have a plastic lining but other than that is there a safety issue with this?

    IDK but that sort of metal exposed to heat may have a tenancy to eventually rust when exposed to fire, usually the seam will go first.
    Have you considered the apx $7 Kmart/Stanco grease pot (not Walmart - that one is different but still could be used)? Very light weight and has proven itself in backpacking circles.

    Funny this should come up now.I asked a friend of mine who works for a major can manufacturer if it is safe to use a coffee can like Sintax 77 does on YouTube.He told me the can is ok.I would have thought that it at least had a lacquer liner sprayed into it but apparently it does not.I notice Sintax painted his with heat resistant paint on the outside.The real question here is why not just go with the grease pot if money is an issue or pick up a used Titanium one off of Ebay?Incidentally,it was a Choc Full O Nuts coffee can if you just have to try it.........

    +1 on the grease pot really a great wide bottom pot OR the IMUSA 10cm or 12cm pots at Walmart you'd have to make a homemade pot lid but that isn't to hard to do.

    the science is not all completely understood, but i dont chance it: aluminum intake is thought by some to be associated with risk factors for many neurovascular issues...parkinsons, alzheimers, etc.

    consequently, I wouldnt recommend this. I dont use anti-antiperspirants, eat acidic foods like tomatoes out of cans, and never heat up aluminum to eat out of.

    Cooking in an aluminum pot is probably the least effective way to introduce the metal into the body. Don't worry about it.

    As for the coffee can, it probably isn't going to hurt you either, but it's probably not going to last too long. The galvanized coating on the steel will break down with heat and then the can will start to rust. That might be the reason Sintax 77 painted his with heat resistant paint.

    I can see cooking in a can in an emergency when there are no other vessels available, but to save money on a proper cook pot? That's just silly. Cook pots aren't all that expensive unless you want one made of titanium. Go to a thrift store and you can find a suitable pot for 50 cents.

    Use an aluminum can or something made from stainless steel...they really aren't that expensive...you can get something at Walmart for a couple of bucks. There used to be recipes for making pumpkin bread in tin cans but they have since said that this is not recommended. Use something that was built for the purpose you intend to use it. We're not talking about buying an $800 sleeping bag here...the amount you save by trying to dirtbag this is really pretty negligible.

    Aluminium is used as a flocculant in most municipal water systems. I'm pretty sure that when you get Out There you'll subtract more aluminium (by not drinking city water) than you add by cooking in an Al pot. Also, for many of us, the chief sources of dietary aluminium is the natural Al present in things like potatoes and tea.

    Once in a while, you'll see a study that trumpets some sort of correlation between Al and neurodegenerative disease. I don't think that the literature is controlling adequately for the green jelly bean effect. (Also note the text you get when you hover the mouse over it!) That effect is very real, leading some to claim that most published findings are false.

    There is some controversy over whether the effect exists. There is no controversy that the magnitude of the effect is very small, or many, many more studies would have detected it.

    There are much greater, proven ways to reduce your risk.
    • Monitor blood pressure, blood sugar, lipid profile and treat hypertension, hyperlipidemia and diabetes aggressively.
    • Eat a good diet - low in saturated fat, high in unsaturated fats, fruits and vegetables. Get enough vitamin D and ω-3 fatty acids.
    • Lead an active lifestyle. Not much of a problem for this audience, I reckon!
    • If you don't smoke, don't start. If you do smoke, quit.
    • Don't drink to excess. (Drinking in moderation is fine, and might have a small protective effect.)
    • Keep up social relationships (family and friends, going to movies, clubs, church, volunteer work) as you age.
    • Keep up mental activity as you age. Continue to read and learn.

    These lifestyle factors are associated not only with risks of mortality from other causes but specifically with risks of dementia.

    I worry more about red40, artificial sweeteners, and sodium than I do about metals. Actually that is not accurate. I don't worry about any of them. I avoid the first two, limit the 3rd while off the trail, consume mega doses of the 3rd while on the trail, and give no thought to the last one except in internet blogs.

    I've considered it but it's made of aluminum and aluminum is supposed to be VERY bad to cook out of, which is why since the mid-90s it's very hard to find any more aluminum cookware in people's homes and if something is aluminum, it almost always has a copper bottom. I think that the new "anodized" aluminum is supposed to make it safer but the Stanco grease pot isn't anodized and I don't want to take a risk with something like that, personally. It's all well and good until you're older and start showing symptoms, you know?

    Thanks for the suggestion, I suppose, but I wasn't asking for suggestions. My question was whether you have any experience with coffee can pots or whether you have any information about if they are safe or not. A suggestions thread would be different.

The galvanized coating on the steel will break down with heat and then the can will start to rust. That might be the reason Sintax 77 painted his with heat resistant paint. I can see cooking in a can in an emergency when there are no other vessels available, but to save money on a proper cook pot? That's just silly. Cook pots aren't all that expensive unless you want one made of titanium. Go to a thrift store and you can find a suitable pot for 50 cents.
    That was a very rude way to start a reply but then you actually answered my question, which I really appreciate. I actually have heat resistant paint, so I might go that route, but I'll probably stop at a thrift store first. Definitely not going to use aluminum because some guy saying that it is "probably the least effective way to introduce the metal into the body" isn't exactly science and I'd rather not take the risk.

    Campsaver.com has the Olicamp LT pot (the one without the integrated heat ex-changer) on sale for $14 (web site says only 2 left in stock... normally $20)

    Aluminum reacts with the oxygen in the air to form Aluminum oxide. If you scratch aluminum, within seconds a new layer of oxide will form. This protects aluminum from further oxidation and makes it hard to react with other chemicals as it binds up the free electrons in the aluminum atom. One of the few things which will attack aluminum is Ferric Chloride, a highly reactive compound your not going to find in food. Water will not react with aluminum, nor will any of the mildly acidic foods you might cook, like tomato sauce.

    Getting too much aluminum in your system might be bad for you, but your not going to get it using aluminum cookware. The reason aluminum pots sometimes have a copper bottom is to distribute the heat, since aluminum is actually a fairly poor conductor of heat.

    Back to the original question of is cooking in a coffee can bad for you? I did some additional google research for you.

    Steel cans are coated with tin to prevent corrosion. I found this statement from Wikipedia:
    Although tin is corrosion resistant, acidic food like fruits and vegetables can cause corrosion of the tin layer. Nausea, vomiting, and diarrhea have been reported after ingesting canned food containing 200 mg/kg of tin
    In addition, most cans are coated on the inside with an epoxy which contains "BPA" which some claim is also bad for you. So, cooking in a coffee can could very well lead to inducing high levels of BPA and then tin into your food. Doing this once or twice won't kill you, but I'd be reluctant to do it on a regular bases. You'd be much better off with aluminum.

    FWIW,the research I did indicated that one would have to eat 500 pounds of canned food per day for a lifetime to get harmful amounts of BPA.However,the research was not based on people that put pre-used cans on a campfire to cook in.The term "tin can" is a misnomer now as almost all cans in the food industry are now "steel cans" and are lined with a foodgrade lacquer or the more noticeable white lining.Personally I would not cook in a can and I quit aluminum cookware for home use a long time ago which may or may not have been the result of "urban legend".However,the can in question is a Choc Full O Nuts coffee can and I have been told that it would be safe to cook in which surprises me as I would think it would have had a sprayed on finish as a protector.
    Maybe the amount of residual would be so far below threshold levels as to not matter but I would not do it.My own pot is the 1 liter Evernew Titanium.I actually wonder about it but doubt it is a concern or ever will be.That said,as I mentioned earlier,I can't drink coffee out of my smaller titanium Snowpeak.Maybe it was just the coffee but it was pretty bad as I recall.
