Poligny, Jura
Poligny () is a commune in the Jura department in Bourgogne-Franche-Comté in eastern France. The town stands at the foot of the first plateau of the Jura region, with limestone cliffs rising to its east and south, and a steephead valley leading to the village of Vaux-sur-Poligny to the east. On the cliffs to the east is a notable cave, known as "Le Trou de la Lune" (the Moonhole); on the cliffs to the south is a large cross, the "Croix du Dan". A network of hiking trails surrounds the town and provide routes to both these viewpoints, and the GR 59 long distance footpath runs through the town. First Empire general Jean-Pierre Travot was born in Poligny; a statue in his honour stands in the principal square of the town, the Place des Déportés, and a road is named after him. Poligny is served by the railway line from Besançon to Lons-le-Saunier. The town is recognised as the " Capital of Comté", with a third of the region's production of this much-loved cheese being ag ...

Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the "Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called che ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 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 cord (later cambric) impregnated with chemicals, and allowed to burn continuously. These were used to light fires and fire guns (see matc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Louis Gay-Lussac
Joseph Louis Gay-Lussac (, , ; 6 December 1778 – 9 May 1850) was a French chemist and physicist. He is known mostly for his discovery that water is made of two parts hydrogen and one part oxygen (with Alexander von Humboldt), for two laws related to gases, and for his work on alcohol–water mixtures, which led to the degrees Gay-Lussac used to measure alcoholic beverages in many countries. Biography Gay-Lussac was born at Saint-Léonard-de-Noblat in the present-day department of Haute-Vienne. The father of Joseph Louis Gay, Anthony Gay, son of a doctor, was a lawyer and prosecutor and worked as a judge in Noblat Bridge. Father of two sons and three daughters, he owned much of the Lussac village and usually added the name of this hamlet of the Haute-Vienne to his name, following a custom of the Ancien Régime. Towards the year 1803, father and son finally adopted the name Gay-Lussac. During the Revolution, on behalf of the Law of Suspects, his father, former king's att ...

Potassium Chlorate
Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the molecular formula KClO3. In its pure form, it is a white crystalline substance. After sodium chlorate, it is the second most common chlorate in industrial use. It is a strong oxidizing agent and its most important application is in safety matches. In other applications it is mostly obsolete and has been replaced by safer alternatives in recent decades. It has been used * in fireworks, propellants and explosives, * to prepare oxygen, both in the lab and in chemical oxygen generators, * as a disinfectant, for example in medical mouthwashes, * in agriculture as an herbicide. Production On the industrial scale, potassium chlorate is produced by the salt metathesis reaction of sodium chlorate and potassium chloride: : NaClO3 + KCl → NaCl + KClO3 The reaction is driven by the low solubility of potassium chlorate in water. The equilibrium of the reaction is shifted to the right hand side by the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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..

Gum Arabic
Gum arabic, also known as gum sudani, acacia gum, Arabic gum, gum acacia, acacia, Senegal gum, Indian gum, and by other names, is a natural gum originally consisting of the hardened sap of two species of the ''Acacia'' tree, '' Senegalia senegal'' and '' Vachellia seyal.'' The term "gum arabic" does not legally indicate a particular botanical source, however. The gum is harvested commercially from wild trees, mostly in Sudan (80%) and throughout the Sahel, from Senegal to Somalia. The name "gum Arabic" (''al-samgh al-'arabi'') was used in the Middle East at least as early as the 9th century. Gum arabic first found its way to Europe via Arabic ports, so retained its name. Gum arabic is a complex mixture of glycoproteins and polysaccharides, predominantly polymers of arabinose and galactose. It is soluble in water, edible, and used primarily in the food industry and soft-drink industry as a stabilizer, with E number E414 (I414 in the US). Gum arabic is a key ingredient in t ...

John Walker (inventor)
John Walker (29 May 1781 – 1 May 1859) was an English inventor who invented the friction match. Life Walker was born in Stockton-on-Tees, County Durham, on 1781. He went to the local grammar school and was afterwards apprenticed to Watson Alcock, the principal surgeon of the town, serving him as an assistant. He had, however, an aversion to surgical operations, and had to leave the profession, turning instead to chemistry. After studying at Durham and York, he set up a small business as a chemist and druggist at 59 High Street, Stockton, around 1818. Walker died in Stockton on 1 May 1859 and was buried in the grounds of St Mary's Church in Norton, near Stockton. Walkers Friction Match He developed an interest in trying to find a means of obtaining fire easily. Several chemical mixtures were already known which would ignite by a sudden explosion, but it had not been found possible to transmit the flame to a slow-burning substance like wood.

Berne Convention (1906)
__NOTOC__ The Berne Convention (formally, the International Convention respecting the Prohibition of the Use of White (Yellow) Phosphorus in the Manufacture of Matches (french: Convention internationale sur l'interdiction de l'emploi du phosphore blanc (jaune) dans l'industrie des allumettes)) of 1906 is a multilateral treaty negotiated in Berne, Switzerland, which prohibits the use of white phosphorus in the manufacture of matches. The treaty also prohibits the import and sale of such matches. The background to the treaty was the extensive medical problems such as phossy jaw facing workers in match production. The treaty was concluded on 26 September 1906. It entered into force on 1 January 1912. The Convention remains in force for 48 states. Switzerland is the depositary for the treaty. In 1925 Edward J. Phelan, future Director General of the International Labour Organization, stated that the establishment of the ILO "may in one sense be traced to the Berne Convention of 19 ...
