Do-It-Yourself: How to Make Charcloth For Every Survival Kit
In an emergency, many media “experts” promote different ways to make sparks as a way to ignite a fire. But the advice sometimes fizzles out there. There may be a vague reference to catching the spark with some material called “tinder.”

Charcloth, made from old denim, will catch any spark and should be included in every survival kit! The finished product should be completely black, but flexible and not brittle.

Sometimes tree fungus, or dry, rotted wood called “punk” is mentioned as a spark catcher. The media personality makes a spark somehow, there is a camera angle change, and presto! We have ignition!
But in the real world, during an emergency, there isn’t time to search for such specialized items, even if they are available, and even if they do work.
Of all the firemaking tools at your disposal, charcloth is one that should be included in every survival kit. It works with every method of firemaking.
Charcloth is a material, usually 100 percent cotton, that has been “cooked” like charcoal at high temperatures until it becomes black and flexible. Properly-made charcloth will easily catch a spark from any source and will spread into an ember.
A spark can come from a flint and steel, flint stick, broken lighter, jumper cables and battery etc. You could even light charcloth with a damp match that flares but won’t ignite. In fact, if you only have a few matches, (and matches are always a finite resource) your best move might be to light some charcloth.
Once caught, a spark on charcloth is virtually impossible to blow out. If the tinder bundle and small kindling are ready, it should only take about a one-inch square of glowing charcloth to get a fire going.

Carry survival gear in your wallet. I always have (from left) firestarter, charcloth and a signal mirror with me.
Lighted charcloth extinguishes easily with water. But all you have to do is dry the soaked material out and it will work again.
Maybe the best thing about charcloth is that you make it yourself, and the materials are free. (Click here to learn how to make it!)
You could even make charcloth while you’re lost if you took along a bandanna and an Altoids or similar tin. (It will give you something to do while sitting by your signal fire, waiting to be rescued!)
You can also try charring some organic materials, such as tree bark (cedar and juniper) and others. There might be a great natural charring material in your area, just waiting to be discovered.
It goes without saying that any experimenting should first be done in your backyard!









Re: using denim, from this article: http://www.survivalcommonsense.com/2010/03/27/make-charclothfeed/
“Blue denim from old Wranglers or Levi 501s or work jeans works very well as the material to be charred. Other 100 percent cotton items and some organic materials can also be used. Another favorite material is 100 percent cotton insulated underwear. We favor denim because there is never a shortage of old jeans in any group of growing boys!”
What do you think of denim as the raw material for charcloth? I wear out plenty of work jeans and have always thrown them away. Maybe there is a better use for old denim.
I guess that my problem is generating the flame from the ember. I don’t have a real problem igniting the charcloth.
Charcloth is for catching the spark. It won’t produce flames, but it will produce an ember that can readily be blown into a flame. The beauty of charcloth is that is can be used to catch any spark, and it is windproof!
I haven’t had much success using charcloth as tinder. I’v tried it several times and don’t seem to be able to start a fire, even though I get the charcloth burning. I’ve had much greater success using cotton balls with a bit of Vaseline. One strike usually starts a fire. I tried using hand sanitizer (gelled alcohol), but it doesn’t work well at all when using a firesteel. Probably too little alcohol in the fluid. I need to try the waxed denim firestarter that you’ve used.
