Firelighting Using Friction
Fire 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. Archaeology Evidence for fire making dates to at least the early Middle Paleolithic, with dozens of Neanderthal hand axes from France exhibiting use-wear traces suggesting these tools were struck with the mineral pyrite to produce sparks around 50,000 years ago. At the Neolithic site of La Draga, researchers have found that fungi were used as tinder. Hearths are one of the most common features found at archaeological sites.

Pyrite
The mineral pyrite (), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of ''fool's gold''. The color has also led to the nicknames ''brass'', ''brazzle'', and ''Brazil'', primarily used to refer to pyrite found in coal. The name ''pyrite'' is derived from the Greek (), 'stone or mineral which strikes fire', in turn from (), 'fire'. In ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel; Pliny the Elder described one of them as being brassy, almost certainly a reference to what we now call pyrite. By Georgius Agricola's time, , the term had become a generic term for all of the sulfide minerals. Pyrite is usually found associated with other sulfides or oxides in quartz ...

Charcloth
Char cloth, also called char paper, is a material with low ignition temperature, used as tinder when lighting a fire. It is the main component in a tinderbox. It is a small swatch of fabric made from a natural fibre (such as linen, cotton, jute etc.) that has been converted through pyrolysis. Description Char cloth looks like a black, fragile piece of cloth. It is usually made from swatches of organic fabrics, but similar tinder can be made in the same way using cotton balls or tampons, dried moss, leaves or fungus ( amadou for instance), raw unspun flax, etc. This is packed into a small, almost airtight, rectangular tin, then heated slowly and steadily over coals for a long period of time, allowing it to undergo thermal decomposition (aka, pyrolysis). The material that remains after this process is complete ignites very easily, making it the preferred tinder when lighting a fire using flint and steel. Pyrolysis is defined as "a thermochemical decomposition of organic material ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flame
A flame (from Latin '' flamma'') is the visible, gaseous part of a fire. It is caused by a highly exothermic chemical reaction taking place in a thin zone. When flames are hot enough to have ionized gaseous components of sufficient density they are then considered plasma. Mechanism Color and temperature of a flame are dependent on the type of fuel involved in the combustion, as, for example, when a lighter is held to a candle. The applied heat causes the fuel molecules in the candle wax to vaporize (if this process happens in inert atmosphere without oxidizer, it is called pyrolysis). In this state they can then readily react with oxygen in the air, which gives off enough heat in the subsequent exothermic reaction to vaporize yet more fuel, thus sustaining a consistent flame. The high temperature of the flame causes the vaporized fuel molecules to decompose, forming various incomplete combustion products and free radicals, and these products then react with each other a ...

Ember
An ember, also called a hot coal, is a hot lump of smouldering solid fuel, typically glowing, composed of greatly heated wood, coal, or other carbon-based material. Embers (hot coals) can exist within, remain after, or sometimes precede, a fire. Embers are, in some cases, as hot as the fire which created them. They radiate a substantial amount of heat long after the fire has been extinguished, and if not taken care of properly can rekindle a fire that is thought to be completely extinguished and can pose a fire hazard. In order to avoid the danger of accidentally spreading a fire, many campers pour water on the embers or cover them in dirt. Alternatively, embers can be used to relight a fire after it has gone out without the need to rebuild the fire – in a conventional fireplace, a fire can easily be relit up to 12 hours after it goes out, provided that there is enough space for air to circulate between the embers and the introduced fuel. They are often used for cook ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flint
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Flint was widely used historically to make stone tools and start fires. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.''The Flints from Portsdown Hill'' Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along streams and [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tinder Fungus
''Fomes fomentarius'' (commonly known as the tinder fungus, false tinder fungus, hoof fungus, tinder conk, tinder polypore or ice man fungus) is a species of fungal plant pathogen found in Europe, Asia, Africa and North America. The species produces very large polypore fruit bodies which are shaped like a horse's hoof and vary in colour from a silvery grey to almost black, though they are normally brown. It grows on the side of various species of tree, which it infects through broken bark, causing rot. The species typically continues to live on trees long after they have died, changing from a parasite to a decomposer. Though inedible, ''F. fomentarius'' has traditionally seen use as the main ingredient of amadou, a material used primarily as tinder, but also used to make clothing and other items. The 5,000-year-old Ötzi the Iceman carried four pieces of ''F. fomentarius'', concluded to be for use as tinder. It also has medicinal and other uses. The species is bo ...

Ötztal Alps
The Ötztal Alps ( it, Alpi Venoste, german: Ötztaler Alpen) are a mountain range in the Central Eastern Alps, in the State of Tyrol in western Austria and the Province of South Tyrol in northern Italy. Geography The Ötztal Alps are arrayed at the head of the Ötztal valley, a side valley of the Inn river southwest of Innsbruck, Austria. One line of summits forms part of the border between Austria and Italy. The Ötztal Alps are bordered by the Reschen Pass (1504 m) in the west and the Inn river in the northwest and north. In the east the range is separated from the Stubai Alps by the Ötztaler Ache in the Ötztal, the Timmelsjoch (2474 m) and the Passer river in the Passeier Valley. On the south and southwest, the range is limited by the deep valley of the Etsch river, here known as the Vinschgau. The Ötztal Alps are surrounded by the following ranges: * Lechtal Alps * Mieming Range * Stubai Alps * Sarntal Alps * Ortler Alps * Sesvenna Alps * Samnaun Alps ...

Natural Mummy
A mummy is a dead human or an animal whose soft tissues and organs have been preserved by either intentional or accidental exposure to chemicals, extreme cold, very low humidity, or lack of air, so that the recovered body does not decay further if kept in cool and dry conditions. Some authorities restrict the use of the term to bodies deliberately embalmed with chemicals, but the use of the word to cover accidentally desiccated bodies goes back to at least 1615 AD (see the section Etymology and meaning). Mummies of humans and animals have been found on every continent, both as a result of natural preservation through unusual conditions, and as cultural artifacts. Over one million animal mummies have been found in Egypt, many of which are cats. Many of the Egyptian animal mummies are sacred ibis, and radiocarbon dating suggests the Egyptian Ibis mummies that have been analyzed were from time frame that falls between approximately 450 and 250 BC. In addition to the mummies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ötzi
Ötzi, also called the Iceman, is the natural mummy of a man who lived some time between 3350 and 3105 BC, discovered in September 1991 in the Ötztal Alps (hence the nickname "Ötzi") on the border between Austria and Italy. Ötzi is believed to have been murdered, due to the discovery of an arrowhead embedded in his left shoulder and various other wounds. The nature of his life and the circumstances of his death are the subject of much investigation and speculation. He is Europe's oldest known natural human mummy, offering an unprecedented view of Chalcolithic (Copper Age) Europeans. His body and belongings are displayed in the South Tyrol Museum of Archaeology in Bolzano, South Tyrol, Italy. Discovery Ötzi was found on 19 September 1991 by two German tourists, at an elevation of on the east ridge of the Fineilspitze in the Ötztal Alps on the Austrian–Italian border, near Similaun mountain and the Tisenjoch pass.
