A plastic soap box or other similiar airtight container,a baby food jar is good too if you have space.
A handfull of cotton balls.
Pack your container with the cotton balls and pour in some used motor oil,let it soak in and add some more.
Now you have some hot burning tinder to use in those less than ideal conditions!
Motor Oil gives of lots of black smoke and toxic fumes.
Glass jars break break easily.
A much better alternative is cotton balls,
(I keep the 'long' cotton that comes out of the top of pill bottles)
And plain old discount Petroleum Jelly.
If you are just starting a fire for heat/light and not cooking over it,
You can try cotton or cotton cloth strips, like old blue jean material or even news paper, and petroleum grease, like any old axle grease.
Petroleum Jelly makes MUCH less smoke, much less fumes, and you can mix up the cotton/petroleum jelly in any old plastic bag.
It's Water Proof (petroleum jelly won't let the water soak into the cotton fibers),
And will start burning with nothing more than a striker tool.
If you want a longer burning tinder/fuel then use paraffin wax with cardboard or cotton.
(about any kind of cellulose material)
I use a lot of cardboard/paraffin fire starters/stoves because they are self sealing,
IE: Waterproof, and burn a good long time with good heat,
I use cotton/petroleum jelly tender for the same reason,
Petroleum Jelly has lots of medical uses,
Lip Balm, disinfectant for cuts/scrapes, treatment for gear 'Rubs', (abrasions from boots, packs, belts rubbing skin).
Petroleum Jelly will sooth those insect bites and helps with sun burns on the skin...
Can't do that with used motor oil!
