Fire strikerA fire striker is a piece of carbon steel from which sparks are struck by the sharp edge of flint, chert or similar rock. It is a specific tool used in fire making. Before the invention of matches, percussion fire making was often used to start fires. Before the advent of steel, a variety of iron pyrite or marcasite was used with flint and other stones to produce a high-temperature spark that could be used to create fire. There are indications that the Iceman, also known as Ötzi, may have used iron pyrite to make fire.
Fire makingFire making, fire lighting or fire craft is the process of artificially starting a fire. It requires completing the fire triangle, usually by heating tinder above its autoignition temperature. Fire is an essential tool for human survival and the use of fire was important in early human cultural history since the Lower Paleolithic. Today, it is a key component of Scouting and bushcraft.
TinderTinder 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.
PistonA piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder.
