Summary
Tinder is easily combustible material used to start a fire. Tinder is a finely divided, open material which will begin to glow under a shower of sparks. Air is gently wafted over the glowing tinder until it bursts into flame. The flaming tinder is used to ignite kindling, which in turn is used to ignite the bulk material, to produce a fire. Tinder can be made of any flammable substance, as long as it is finely divided and has an open structure. Any flammable material may be used as long as it is finely divided. As the tinder gets thinner, the surface area and edges increase, making it ignite more easily. Wood tinder can be made by carefully shaving thin slivers off a larger piece. Another method which keeps these slivers together, is to make a feather stick. The driest wood, which makes the best tinder, is that of dead branches that have not yet fallen to the ground. If a fire is to be lit by sparks rather than matches, char cloth, punkwood, fungus or down are commonly used to catch the sparks. However, fungi should be selected with care as some release toxic fumes on combustion. Char cloth can be made by placing plant-based fabric (usually cotton) in a tin box into a campfire; like charcoal, it is the product of anhydrous pyrolysis. It is very fragile, and should usually be prepared only in small quantities. Pitchwood is the resinous wood which decays last from dead conifers. It can be found on the ground where conifer tree trunks have fallen and decayed. The parts of the deadwood that would form the knots in lumber, i.e. the places where branches entered the trunk, are impregnated with resin which has the combustibility of wood soaked in lighter fluid. Pitchwood can also be found in the stumps left in the ground when conifers die. These stumps contain spires of resin-impregnated wood, called fatwood, which can easily be lighted using only a single match or lighter. Pitchwood that has been shaved into small splinters is easy to ignite, and it does not absorb water, so it remains easy to ignite in any weather as long as the flame is sheltered from rain and wind.
