Match (2012 Film)
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, 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. Etymology Historically, the term ''match'' referred to lengths of cord (later cambric) impregnated with chemicals, and allowed to burn continuously. These were used to light fires and fire guns (see matchlock) and cannons (see linstock) and to detonate explosive devices such as dynamite sticks. ...

Fuse (explosives)
In an explosive, pyrotechnics, pyrotechnic device, or military munition, a fuse (or fuze) is the part of the device that initiates function. In common usage, the word fuse is used indiscriminately. However, when being specific (and in particular in a military context), the term ''fuse'' describes a simple pyrotechnic initiating device, like the cord on a firecracker whereas the term ''fuze'' is used when referring to a more sophisticated ignition device incorporating mechanical and/or electronics, electronic components, such as a proximity fuze for an M107 projectile, M107 artillery shell, magnetometer, magnetic or acoustic signature, acoustic fuze on a sea mine, spring-loaded grenade fuze, pencil detonator, or anti-handling device. History Documented evidence suggests that the earliest fuses were first used by the Song Chinese between the 10th and 12th centuries. After the Chinese invented gunpowder, they began adapting its explosive properties for use in military technology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Wright Of Derby The Alchemist
Joseph is a common male given name, derived from the Hebrew Yosef (יוֹסֵף). "Joseph" is used, along with "Josef", mostly in English, French and partially German languages. This spelling is also found as a variant in the languages of the modern-day Nordic countries. In Portuguese and Spanish, the name is "José". In Arabic, including in the Quran, the name is spelled '' Yūsuf''. In Persian, the name is "Yousef". The name has enjoyed significant popularity in its many forms in numerous countries, and ''Joseph'' was one of the two names, along with ''Robert'', to have remained in the top 10 boys' names list in the US from 1925 to 1972. It is especially common in contemporary Israel, as either "Yossi" or "Yossef", and in Italy, where the name "Giuseppe" was the most common male name in the 20th century. In the first century CE, Joseph was the second most popular male name for Palestine Jews. In the Book of Genesis Joseph is Jacob's eleventh son and Rachel's first son, and k ...

Marco Polo
Marco Polo (, , ; 8 January 1324) was a Venetian merchant, explorer and writer who travelled through Asia along the Silk Road between 1271 and 1295. His travels are recorded in ''The Travels of Marco Polo'' (also known as ''Book of the Marvels of the World '' and ''Il Milione'', ), a book that described to Europeans the then mysterious culture and inner workings of the Eastern world, including the wealth and great size of the Mongol Empire and China in the Yuan Dynasty, giving their first comprehensive look into China, Persia, India, Japan and other Asian cities and countries. Born in Venice, Marco learned the mercantile trade from his father and his uncle, Niccolò and Maffeo, who travelled through Asia and met Kublai Khan. In 1269, they returned to Venice to meet Marco for the first time. The three of them embarked on an epic journey to Asia, exploring many places along the Silk Road until they reached Cathay (China). They were received by the royal court of Kublai Khan, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hangzhou
Hangzhou ( or , ; , , Standard Mandarin pronunciation: ), also romanized as Hangchow, is the capital and most populous city of Zhejiang, China. It is located in the northwestern part of the province, sitting at the head of Hangzhou Bay, which separates Shanghai and Ningbo. Hangzhou grew to prominence as the southern terminus of the Grand Canal and has been one of China's most renowned and prosperous cities for much of the last millennium.

Five Dynasties And Ten Kingdoms
The Five Dynasties and Ten Kingdoms period (), from 907 to 979, was an era of political upheaval and division in 10th-century Imperial China. Five dynastic states quickly succeeded one another in the Central Plain, and more than a dozen concurrent dynastic states were established elsewhere, mainly in South China. It was a prolonged period of multiple political divisions in Chinese imperial history. Traditionally, the era is seen as beginning with the fall of the Tang dynasty in 907 and reaching its climax with the founding of the Song dynasty in 960. In the following 19 years, Song gradually subdued the remaining states in South China, but the Liao dynasty still remained in China's north (eventually succeeded by the Jin dynasty), and the Western Xia was eventually established in China's northwest. Many states had been ''de facto'' independent long before 907 as the Tang dynasty's control over its officials waned, but the key event was their recognition as sovereign by foreig ...

Northern Qi
Qi, known as the Northern Qi (), Later Qi (後齊) or Gao Qi (高齊) in historiography, was a Chinese imperial dynasty and one of the Northern dynasties during the Northern and Southern dynasties era. It ruled the eastern part of northern China from 550 to 577. The dynasty was founded by Gao Yang (Emperor Wenxuan), and was eventually conquered by the Northern Zhou dynasty in 577. History Northern Qi was the successor state of the Chinese Xianbei state of Eastern Wei and was founded by Emperor Wenxuan. Emperor Wenxuan had an Han father of largely Xianbei culture, Gao Huan, and a Xianbei mother, Lou Zhaojun. As Eastern Wei's powerful minister Gao Huan was succeeded by his sons Gao Cheng and Gao Yang, who took the throne from Emperor Xiaojing of Eastern Wei in 550 and established Northern Qi as Emperor Wenxuan. Northern Qi was the strongest state out of the three main states (the other two being Northern Zhou state and Chen Dynasty) in China when Chen was established. Northern ...

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 production o ... [...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 ...

Sparkler
A sparkler is a type of hand-held firework that burns slowly while emitting bright, intense colored flames, sparks, and other effects. Sparklers are particularly popular with children. In the United Kingdom, a sparkler is often used by children at bonfire and fireworks displays on Guy Fawkes Night, the fifth of November, and in the United States on Independence Day. They are called ''phuljhadi'' in Hindi and are especially popular during the Diwali festival. Composition Sparklers are generally formed around a thin non-combustible metallic wire, about 8-12 inches (20-30 cm) long, that has been dipped in a thick batter of slow-burning pyrotechnic composition and allowed to dry. The combustible coating contains these components, one or more of each category: * Metallic fuel, mandatory to make sparks; size of particles influences appearance of the sparks ** Aluminium or magnesium or magnalium, producing white sparks ** Iron, producing orange branching sparks ** T ...

Firework
Fireworks are a class of low explosive pyrotechnic devices used for aesthetic and entertainment purposes. They are most commonly used in fireworks displays (also called a fireworks show or pyrotechnics), combining a large number of devices in an outdoor setting. Such displays are the focal point of many cultural and religious celebrations. Fireworks take many forms to produce four primary effects: noise, light, smoke, and floating materials (confetti most notably). They may be designed to burn with colored flames and sparks including red, orange, yellow, green, blue, purple and silver. They are generally classified by where they perform, either 'ground' or 'aerial'. Aerial fireworks may have their own propulsion (skyrocket) or be shot into the air by a mortar ( aerial shell). Most fireworks consist of a paper or pasteboard tube or casing filled with the combustible material, often pyrotechnic stars. A number of these tubes or cases may be combined so as to make when kind ... [...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 propellant but is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
