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 ...

Matchbook
A matchbook is a small paperboard folder (known as a matchcover) enclosing a quantity of matches and having a coarse striking surface on the exterior. The folder is opened to access the matches, which are attached in a comb-like arrangement and must be torn away before use in contrast to a matchbox where the matches are loosely packed in the interior tray. The exterior of the matchcover is usually imprinted with a producer's logo, often with artistic decorations, or serves as an advertising/promotional medium for the undertaking by which it is sold or given away. The ease of making matchcovers of different shapes also made them quite a popular cheap promotional item or anniversary souvenir. Manufacturing of matchbooks peaked during the 1940s and 1950s, then steadily declined because of the availability of disposable lighters and various anti-smoking health campaigns. Recently, matchbooks have begun to regain some of their popularity as a "retro" advertising item, particularl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matchbox
Phillumeny (also known as phillumenism) is the hobby of collecting different match-related items: matchboxes, matchbox labels, matchbooks, matchcovers, matchsafes, etc. Matchbox A matchbox is a box made of cardboard or thin wood and designed to hold matches. It usually has a coarse striking surface on one edge for lighting the matches contained inside. Etymology The word, derived from Greek phil- oving+ Latin lumen- ight was introduced by the British collector Marjorie S. Evans in 1943 (who later became president of the British Matchbox Label & Booklet Society, now renamed the British Matchbox Label and Bookmatch Society). A person who engages in phillumeny is a ''phillumenist''. These two forms have been adopted by many other languages, e.g., ''philuméniste'', ''fillumenista'', ''Filumenist'' and филуменист. Phillumeny worldwide Collecting of matchbox labels emerged together with matches. In some collections it is possible to find labels from chemical matches ...

Slow Match
Slow match, also called match cord, is the slow-burning cord or twine fuse used by early gunpowder musketeers, artillerymen, and soldiers to ignite matchlock muskets, cannons, shells, and petards. Slow matches were most suitable for use around black-powder weapons because a slow match could be roughly handled without going out, and only presented a small glowing tip instead of a large flame that risked igniting nearby gunpowder. Slow match of various types was one of the first kinds of artillery fuse. Slow matches were also used in the drilling and blasting of rock to ignite charges of gunpowder. Design and use The slow match attached to the lock of the matchlock gun was usually a length of hemp or flax cord that had been chemically treated to make it burn slowly and consistently for an extended period. In Japan, however, match cord was made from braiding together strands of bark from the Japanese cypress. The rate of burning was approximately 1 ft (305mm) per hour. ...

Matchlock
A matchlock or firelock is a historical type of firearm wherein the gunpowder is ignited by a burning piece of rope that is touched to the gunpowder by a mechanism that the musketeer activates by pulling a lever or trigger with his finger. Before the invention of the matchlock mechanism, the musketeer or an assistant had to apply the match directly to gunpowder by hand, much like a cannon. The matchlock mechanism allowed the musketeer to apply the match himself without losing his concentration. Description The classic matchlock gun held a burning slow match in a clamp at the end of a small curved lever known as the ''serpentine''. Upon the pull of a lever (or in later models a trigger) protruding from the bottom of the gun and connected to the serpentine, the clamp dropped down, lowering the smoldering match into the flash pan and igniting the priming powder. The flash from the primer traveled through the touch hole, igniting the main charge of propellant in the gun barre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannon
A cannon is a large-caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge, effective range, mobility, rate of fire, angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. In the modern era, the term ''cannon'' has fallen into decline, replaced by ''guns'' or ''artillery'', if not a more specific term such as howitzer or mortar, except for high-caliber automatic weapons firing bigger rounds than machine guns, called autocannons.

Friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding (motion), sliding against each other. There are several types of friction: *Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into ''static friction'' ("stiction") between non-moving surfaces, and ''kinetic friction'' between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as Asperity (materials science), asperities (see Figure 1). *Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. *Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. *Skin friction is a component of Drag (physics), drag, the force resisting the motion of a fluid across the surface of a body. *Internal friction is t ...

Fire
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction Product (chemistry), products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The ''flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce Plasma (physics), plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's Intensity (heat transfer), intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Powder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate ( saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Candle Wick
A candle wick is usually a braided cotton that holds the flame of an oil lamp or candle. A candle wick works by capillary action, conveying ("wicking") the fuel to the flame. When the liquid fuel, typically melted candle wax, reaches the flame it then vaporizes and combusts. The candle wick influences how the candle burns. Important characteristics of the wick include diameter, stiffness, fire-resistance, and tethering. Wick types Candle wicks are normally made out of braided cotton.Franz Willhöft and Rudolf Horn "Candles" in Ullmann's Encyclopedia of Industrial Chemistry, 2000, Wiley-VCH, Weinheim. Wicks are sometimes braided flat, so that as they burn they also curl back into the flame, thus making them self-consuming. Prior to the introduction of these wicks specialty scissors were used to trim the excess wick without extinguishing the flame. Large diameter wicks typically result in a larger flame, a larger pool of melted wax, and the candle burning faster. In tealigh ...

Sulfur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the producti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
