Step 2: What Is Char Cloth?
According to Wikipedia;
"Char cloth (also called charpaper) is a swatch of fabric made from vegetable fiber (such as linen, cotton or jute) that has been converted via pyrolysis into a slow-burning fuel of very low ignition temperature.
It is capable of being ignited by a single spark that can in turn be used to ignite a tinder bundle to start a fire.
It is sometimes manufactured at home for use as the initial tinder when cooking or camping and historically usually provided the "tinder" component of a tinderbox. It is often made by putting cloth into an almost airtight tin with a small hole in it, and cooking it in campfire coals until the smoking slows and the cloth is properly charred.
Charcloth ignites with even the smallest spark, and is therefore commonly used with a flint and steel."
I use it as my tinder of choice my acrylic fire piston.
Step 3: Materials You'll Need
- 1. Tuna Can
- 2. "Lid lifter" style can-opener
- 3. Nail, punch, or small screwdriver
- 4. Cotton fabric
I also found that cotton balls work extremely well, and have become my new favorite!
Step 4: Cook the Cotton
- If possible, use a "lid-lifter" style can-opener to open the can. This cuts the top off along the side of the can.
- Clean out your tuna can and make sure it's dry and free of contaminants
- Place 4-8 cotton balls inside the can (Or about 4 round pieces of cotton fabric from your T-shirt)
- Replace the lid and press it back into place. (Note: If you cut it with a "lid-lifter" style can opener it should press and hold together like it was meant to be!)
- Flip the can over, and use your punch to make a small hole in the "top" of the cooker
Step 5: Fire It Up!
- 1. Use solar power via your Solar Scorcher from another project
- 2. Place directly in an open flame
- 3. Any other outdoor method of inducing heat. (Outdoors because potentially harmful gasses will be released and can smell up your house)
You can tell the process is working because you'll see the gas venting through the hole in the top of the container. These gasses are flammable, and may ignite. Don't worry if they do because that's normal and just fine.
The cooking is done when the gas stops and the flame goes out.
Note: I've found that cooking them beyond the point where the gasses stop, and flame goes out, can negatively effect their performance, so take the container off the fire as soon as practical.
- Place a layer of aluminum foil over the hole to prevent air from sucking back into the container.
- Let cool for about 5 minutes
Note: The container is very hot, so use protection on your hands to avoid being burned while applying the foil.
Step 6: How Did It Turn Out?
Note: If there are parts that are still white, or brown, it's not cooked completely and needed more time on the fire.
To test your batch of char-cloth, brush gently with an open flame. The cloth should capture the heat and form a small spark that will continue to smolder for an impressive amount of time. 1 cotton ball can last a couple of minutes.
By blowing air onto the spark, heat will transfer quickly and can engulf the entire cloth.
This is the great advantage of the cloth. It can deliver a lot of heat when you need it (by blowing on it), or just hold a spark for a couple of minutes while you're getting your tinder bundle ready.
