Picture of Better Sterno Alternative

How you pack for the outdoors depends on how you intend to spend your time exploring nature. Packing light seems to be a common goal of campers, hikers and survivalists. Most also agree that it’s wise to have a compact way to cook a meal, boil water, keep warm, and create light that will keep away animals like wolves. For all of these things you need a reliable source of long-lasting fire, but most of us don’t want to carry flammable liquids or gels in our packs. I will show you a safe alternative: a pocket-sized piece of survival gear that you will quickly start to regard as an essential item to pack for your next adventure — no matter what it is.

Can this be lit with a firesteel or do you need matches/ligher?

Stick some cotton in it on top.
The cotton will light easily enough from a firesteel. Those flat cotton swabs women use for removing makeup seems to be just made for the purpose...

Take dryer lint, break it into little pieces, and roll it into little balls with Vaseline on your fingers.

I prefer to dry my clothes on a line outside, so I don't have all that much lint.

But Vaseline is good. Both for starting fires, and... well...

Why little balls?

Wouldn't a larger, flat piece be better for catching a spark?

My apologies for the delayed response; I didn't realize you had replied until just now. Balls are more compact and, therefore, are easier to pack.

It is basically a candle with a very large wick. You need a flame (matches/lighter) to get it going.

Ello! I have a question. I am wanting to make these little guys as food warmers for my steam pans i use. I dont care about soot at all, just need them to keep food warm. I am either going to use this option or sterno but i dont want to have to keep buying sterno at 5$ a can. Hence why i either want to make ethanol gel or these guys. But i need to know how many hours will they last? im looking for something that lasts at least 4-5 hours


Once this has been lit, and burned for a moment, does it melt the wax creating a puddle of wax or does the wax burn off with the flame?
My thought is this; I was at a medieval reenactment event once and a vendor was selling "dripless torches" but I never went and checked them out to see what made them tick. All that I saw as I was walking by was cardboard rolled up inside a larger tin can that was screwed to a wooden stick/handle. I'm curious to know if this was burning and it got tipped over, would wax pour out of it.

It works like a candle in a jar, more-or-less. The wax, whether candle wax of bees wax, will melt more and more as time goes by and the over-all temperature of the wax rises. Bees wax will thoroughly melt quicker than candle wax, however.

Can you add citronella essential oil to the wax before pouring onto the cardboard to have it act as a citronella candle?

Great idea going to try itYarp:-)

We did this way back in the 50s/60s but my concern was that melting aluminum gives off highly toxic fumes, so my question is does this get hot enough to melt the aluminum cans.

Melting aluminum doesn't give off fumes, vaporizing it does though. You'd need to reach a temperature quite a bit higher than you can achieve on your stove or an open campfire. Aluminum vaporizes above 4566ºF.

We made these in the 80's when my son was in Cub Scouts. We used empty tuna cans, dryer lint, cardboard pieces and paraffin wax. It was a great family activity to make them and very useful when camping.

I've been making these for over 20 years, we sometimes include a piece of string in the cardboard to help it light easier and if you have a very large tin with you like a big coffee or milo can with a seal-able lid you can turn one into an instant camp stove. Take the lid of the big tin and turn it upside down, Make several holes in the side of tin near the top edge, if possible do the same around the bottom edge. Light your pocket sized lamp and sit it on the underside of the tin lid, place the big tin over it so that the big tins base is above the flame, now you use it like a cooking plate and make small pancakes or put a pan or billy on to heat your food/water. The holes at the lid side let air in and the holes above the flame help the air to flow through and any smoke.

This is dandy. I love it!. I've never seen one in an altoids can before.

There are a lot of variables but Methanol methyl alcohol has a surface flame temp of about 1910c while wood /wax combo should be around 1970c so they in the same range with wood/wax being slightly higher temp.

I make these for use as survival candles but with a slight twist. I use tomato paste or tuna cans I have opened with one of those can openers that leaves no sharp edge. The lid can be replaced. I tear the cardboard to leave a sort of frayed edge about 3/16" shy of the edge. I preheat the can and cardboard, pour in the wax nearly to the top and replace that lid. If you use one of the can openers that leave a triangle opening, you can light the cardboard through that hole. As the can heats up, you can move the hole around to use a different spot of the can. Want a bigger flame? Make more holes or pry the lid off. I keep a couple in my snowmobile. If i lose it or someone steals it...so what? I'm out less than a $1.

They taught us to do this in the Girl Scouts in the '80s in empty tuna cans. I'd completely forgotten about them. They work great!

Tjesse - Nice ibble - I've seen it before but its always nice to teach things like this to new people. I have a question however - how do you know that this burns hotter than an alcohol stove? Do you have empiracal evidence, or is it hear-say?   Not trying to be smart just wondering if its been fact-checked.
Good job though,
Thank yoiu

Lt.Greg, thanks for showing enough interest to comment!
I can't say that I have found hard data on this, however, I do have experience with both sterno and "buddy burners". Sterno is not the greatest way to bring water to a boil but it can be done, as many sterno fans will tell you. I have not done any side-by-side comparisons, but from my experience this can be a hotter stove as stated in the instructable. "It will last a few hours and CAN be hotter then sterno...". This is a homemade stove so testing against a commercial product is difficult because of different cardboard to wax ratios and even the types of waxes and cardboard. I make this not because it is better, rather, but because its more economical and fun. So to answer the question... hear-say.
Lt.Greg tjesse3 years ago
Hi sir- thanks for the come-back. I'd say you sound like you might be an engineer, except that you didn't give the "Average rated BTU's" in your original ibble! LOL!

Say, I tried this once before and didn't get it right, maybe you can give me some advice. Just how much of a gap should I leave between the cardboard slices? I think I packed it too tightly and couldn't get enough wax into the spaces. You mentioned the idea, but can you expound a little more about what the "proper ratio" of wax to cardboard might be?

Again, nice job, thanks
tjesse (author)  Lt.Greg3 years ago
I'm no engineer but I did stay at a holiday inn express last night. I don't put space between the cardboard. The corrugation has enough spaces in it for the wax. It takes a minute to get to a good temp, I would try lighting the one you made again. Even if it is tightly packed it should work the same just not last as long. The wax, just like in a candle, controls the flame as well as fuels it. If the wax is curing before it soaks in to the cardboard you can try heating the whole thing on the stove. I posted a pic in the comments.
Lt.Greg tjesse3 years ago
I was also thinking - warm up the tin and cardboard a bit, so the wax doesn't solidify before it reaches the bottom of the tin and has a chance to saturate the wick.
Other option: if you have a pot big enough you could pre-soak the cardboard strips in the melted wax. Pull them out and let them cool down enough to handle. Then roll them up and stuff them into the tins.
The melting point of paraffin is between 115 and 154 °F, so you could put several of these in the oven, to keep the wax in a liquid state for a much longer time, allowing it to be wicked into the cardboard.

Parafin vapors or wax vapors will concentrate in the oven causin a dangerous explossion as soon as they reach the fire.
lime3D oraco2 years ago
Not at these temps.
Parrafin has an autoignition temp of 428F - so it's not likely to burn, but the flash point is only between 100 and 162F, so if you're using a gas oven, it's probably going to deflagrate when the vapors hit the pilot light. It's pretty hard to get a Gas oven under 200F. I would bet though, that using a water bath in a slow cooker (Crock Pot) would do just as well with no risk of fire.
"space between the cardboard"

This makes sense to me now. I tried making one a while ago but gave up because I just got shooting flames that went dangerously high. I didn't use a lot of cardboard and there was plenty of space between.
On average, beeswax has 19,000 Btu/lb, paraffin wax has 18,000 Btu/lb, Ethanol has 11,570 Btu/lb. Theoretically, wax is one of the hottest fuels you can burn. The problem is that it doesn't burn as fast as you would need it to in order to compete with an ethanol stove.

I've been experimenting with my own camp cooking stoves and have found that wax tends to be sooty and leave a hard to clean residue on the underside of my cooking pots, this is a real problem since they nest inside one another. Does anyone know how sooty this kind of stove makes your cookware?
you can stop the build up of soot by coating the undersides of your pots with fairy liquid
oraco marccase2 years ago
Cover all the outside of your camping cookware with mud. Let it dry and it's ready to be exposed to wax flames. Then, just wash out the mud and Voila!
Clean as brand new.
marccase oraco2 years ago
Thank you!
If you will take liquid dish soap and smear it liberally on the outside of your cooking pans, then let it dry thoroughly before you put it over the fire, the soot will not collect on your pans and will be MUCH easier to clean. Reapply and let dry after each washing to be ready for the next use.
I'll have to try that next time, thank you.
