Fire building 101
There are three things you need to build a fire oxygen, heat and fuel. Most people refer to this as the fire triangle. Add all of these together you have a chemical reaction.
Heat
Heat is an essential element that a fire needs. A fire cannot start unless there’s a significant amount of heat involved. Here are a few examples of heat sources that you can use in a survival situation or everyday life, friction, magnesium and steel, matches, lighters or the use of electrical components. It is always smart to bring an ignition source with you whenever you go on a hike, hunting or any time you’re away from civilization.
Fuel
Fuel is another very important component. Your fire will need a fuel source in order to continue to burn. The fuel can be anything that’s flammable. It’s important your fuel source is dry and if you remove the fuel from the fire, then it will go out. An example of things you and find that are great for starting fires are extremely small twigs, dead grass, birch bark, other tree bark that is paper thin and dry, tree sap and lint you may find in your pockets. Now keep in mind most tree bark is not a good fire starter. It may look it but do your research on the trees in your location or the location you are traveling and if it makes a good ignition system.
Oxygen
A fire needs oxygen in order to ignite and continue to burn. If you ever put the lid on a lit candle, you would see the flame disappear due to the lack of oxygen. Or if you ever blew into a campfire, you would see the flame rise from a large amount of air flow. Keep in mind to much air is bad for a fire especially if your are trying to start it. Try to use larg logs or rocks to block the wind and use your mouth to control the air flow when you need it. Also never smother your fire because like i said before the lack of air will kill it. Think of the fire as a living thing. It needs Food warmth and Air to survive.
