Tinder
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. Technique 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Char Cloth
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] |
Fatwood
Fatwood, also known as "fat lighter", "lighter wood", "rich lighter", "pine knot", "lighter knot", "heart pine", "fat stick" or "lighter'd", is derived from the heartwood of pine trees. The stump (and tap root) that is left in the ground after a tree has fallen or has been cut is the primary source of fatwood, as the resin-impregnated heartwood becomes hard and rot-resistant over time after the death of the main tree. Other locations, such as the joints where limbs intersect the trunk, can also be harvested. Although most resinous pines can produce fatwood, in the southeastern United States the wood is commonly associated with longleaf pine (''Pinus palustris''), which historically was highly valued for its high pitch production. History The commercial use of fatwood from stumps stemmed from the production of pitch and pine tar. In 1648, a company was formed in Sweden called ''Norrländska Tjärkompaniet'' (The Wood Tar Company of North Sweden), and was given exclusive export ...

Feather Stick
A feather stick (sometimes referred to as a fuzz stick) is a length of wood which has been shaved to produce a cluster of thin curls protruding from the wood. It allows damp wood to be used to start a fire when dry tinder is hard to find. It is believed to be a traditional method of fire starting, using basic tools and methods. Use Feather sticks are made from dead "standing" wood, such as a branch that has broken from a tree and died, but has not yet fallen to the ground.Towell, Colin, and Inc Publishing. Essential survival skills key tips and techniques for the great outdoors. London: DK Pub., 2011. 95. The bark and the outer layer of wood are removed to reveal the drier heartwood. This is then shaved, with axe or knife, to produce as many curls as possible. While the flakes can be fairly coarse, the finer they are shaved the more easily they ignite. Feather sticks can be used with char cloth, where a small piece of the cloth is wound around the curls and a spark is struck ...

Match
A match is a tool for starting a fire. Typically, matches are made of small wooden sticks or stiff paper. One end is coated with a material that can be ignited by friction generated by striking the match against a suitable surface. Wooden matches are packaged in matchboxes, and paper matches are partially cut into rows and stapled into matchbooks. The coated end of a match, known as the match "head", consists of a bead of active ingredients and binder (material), binder, often colored for easier inspection. There are two main types of matches: safety matches, which can be struck only against a specially prepared surface, and strike-anywhere matches, for which any suitably frictional surface can be used. Because of the substance used to coat each match, this makes them non-biodegradable. Etymology Historically, the term ''match'' referred to lengths of rope, cord (later cambric) impregnated with chemicals, and allowed to burn continuously. These were used to light fires and fir ...

Survival Skills
Survival skills are techniques that a person may use in order to sustain life in any type of natural environment or built environment. These techniques are meant to provide basic necessities for human life which include water, food, and shelter. These skills also support proper knowledge and interactions with animals and plants to promote the sustaining of life over a period of time. Survival skills are often associated with the need to survive in a disaster situation. Survival skills are often basic ideas and abilities that ancient people invented and used themselves for thousands of years. Outdoor activities such as hiking, backpacking, horseback riding, fishing, and hunting all require basic wilderness survival skills, especially in handling emergency situations. Bushcraft and primitive living are most often self-implemented but require many of the same skills. First aid First aid (wilderness first aid in particular) can help a person survive and function with injuries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twig
A twig is a thin, often short, branch of a tree or bush. The buds on the twig are an important diagnostic characteristic, as are the abscission scars where the leaves have fallen away. The color, texture, and patterning of the twig bark are also important, in addition to the thickness and nature of any pith of the twig. There are two types of twig: vegetative twigs and fruiting spurs. Fruiting spurs are specialized twigs that generally branch off the sides of branches and are stubby and slow-growing, with many annular ring markings from seasons past. The age and rate of growth of a twig can be determined by counting the winter terminal bud scale scars, or annular ring marking, down the length of the twig. Twigs can be useful in starting fire. They can be used as kindling wood, bridging the gap between highly flammable tinder (dry grass and leaves) and firewood Firewood is any wooden material that is gathered and used for fuel. Generally, firewood is not highly proces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Oxy-fuel Welding And Cutting
Principle of burn cutting Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline or petrol, diesel, bio diesel, kerosene, etc) and oxygen to weld or cut metals. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen-acetylene welding in 1903. Pure oxygen, instead of air, is used to increase the flame temperature to allow localized melting of the workpiece material (e.g. steel) in a room environment. A common propane/air flame burns at about , a propane/oxygen flame burns at about , an oxyhydrogen flame burns at and an acetylene/oxygen flame burns at about . During the early 20th century, before the development and availability of coated arc welding electrodes in the late 1920s that were capable of making sound welds in steel, oxy-acetylene welding was the only process capable of making welds of except ...

Pyrophoric
A substance is pyrophoric (from grc-gre, πυροφόρος, , 'fire-bearing') if it ignites spontaneously in air at or below (for gases) or within 5 minutes after coming into contact with air (for liquids and solids). Examples are organolithium compounds and triethylborane. Pyrophoric materials are often water-reactive as well and will ignite when they contact water or humid air. They can be handled safely in atmospheres of argon or (with a few exceptions) nitrogen. Fire Classes#Metal, Class D fire extinguisher#Class D dry powder and other agents for metal fires, fire extinguishers are designated for use in fires involving pyrophoric materials. A related concept is hypergolic propellant, hypergolicity, in which two compounds spontaneously ignite when mixed. Uses The creation of spark (fire), sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. The sparking mechanisms in lighters and various toys, using fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferrocerium
Ferrocerium (also known in Europe as Auermetall) is a synthetic pyrophoric alloy of mischmetal (cerium, lanthanum, neodymium, other trace lanthanides and some iron – about 95% lanthanides and 5% iron) hardened by blending in oxides of iron and/or magnesium. When struck with a harder material, the mixture produces hot sparks that can reach temperatures of when rapidly oxidized by the process of striking the rod. Striking both scrapes fragments off, exposing them to the oxygen in the air, and easily ignites them by friction heat due to cerium's remarkably low ignition temperature of ~. Its easy flammability gives ferrocerium many commercial applications, such as the ignition source for lighters, strikers for gas welding and cutting torches, deoxidization in metallurgy, and ferrocerium rods. Because of ferrocerium's ability to ignite in adverse conditions, rods of ferrocerium (also called ferro rods, spark rods, and flint-spark-lighters) are commonly used as an emerge ...

Paper Towel
A paper towel is an absorbent, disposable towel made from paper. In Britain, paper towels for kitchen use are also known as kitchen rolls, kitchen paper, or kitchen towels. For home use, paper towels are usually sold in a roll of perforated sheets, but some are sold in stacks of pre-cut and pre-folded layers for use in paper-towel dispensers. Unlike cloth towels, paper towels are disposable and intended to be used only once. Paper towels absorb water because they are loosely woven, which enables water to travel between the fibers, even against gravity ( capillary effect). They have similar purposes to conventional towels, such as drying hands, wiping windows and other surfaces, dusting, and cleaning up spills. Paper towel dispensers are commonly used in toilet facilities shared by many people, as they are often considered more hygienic than hot-air hand dryers or shared cloth towels. History In 1907, the Scott Paper Company of Philadelphia, Pennsylvania, introduced paper tiss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
