These portable fire starters are an easy way to make use of things that would otherwise be discarded. They are simple to make and can be used in an emergency or as a campfire quickstart that can be tossed in your hiking pack. The two ingredients in them, rendered deer fat and hardwood coals, are by-products of our everyday activities that have found a new life as something useful. We use coals produced in our wood stove, but you can use coals from any fire as long as it’s from hardwoods. They can also be made from lots of other things, so just use your imagination!
What you’ll need:
- Rendered fat
- Hardwood coals
- Mortar and pestle (or a flat stone and small rock)
- Small paper cup, like a bathroom “Dixie” cup.
- Mixing bowl
- Something to stir with
- Plastic wrap or something to press with
How to make them:
Using the mortar and pestle or your flat stone, crush some of the fire coals until it’s a fine powder. Melt an equal amount of the fat and mix the two ingredients together in a bowl. 1/4 cup each of coals and fat will make 3 disks that are about 1/2″ thick.
Press the mixture into the bottom of small paper cup, then trim the top of the cup down to level with the firestarter.
The average burn time for one of these is between 14 and 15 minutes and it will go from burning vigorously to completely spent, right at the last minute. Once it’s done, it extinguishes very quickly. Below are progression pictures showing 5, 10 and 13 minutes after lighting. The last picture is of the ashes left when it’s finished.




If you’re packing these to use while out hiking or camping, consider putting the disks in some type of container. It would take a lot of heat to turn the fat back to liquid, but depending on where you are, or if it winds up being accidentally left in direct sun or a hot car, a ziploc bag might be a good safeguard. They stack well, so you could also put them end to end and roll them up in a sheet of plastic wrap or stack them on top of each other inside a pint size canning jar.
We make dryer lint and wax ones too, those things are great! We have used empty toilet paper tubes cut in half but never cardboard egg cartons. That sounds like it would work great, they burn well, so it would probably even be an improvement. We also make a version of the lint and wax starters with dried Sweet Gum tree balls (the spiked ones). 3 of them fit perfectly in an empty toilet paper tube with a cap of lint and wax on each end. I can see those fitting in egg containers too with lint and wax. We are definitely going to have to play around with this a bit! Thanks!
I have made fire starters our of dryer lint and wax in cardboard egg containers. Have you tried your recipe in the egg containers instead of bathroom cups? Based on experience, do you think it would make these burn easier? Longer? Shorter? Any thoughts are appreciated 🙂
Thanks for doing all this work!
