Sunday Stone

picture info	Sunday Stone Sunday stone is an artificial stone composed of porous barium sulfate that formed on the walls of drainage pipes of some coal mines. It is striped due to differing levels of coal dust produced during the day and night shifts. In some cases there is a broader stripe generated every seven days due to active mining not taking place on a Sunday. Broader stripes would also appear when work stopped for other reasons. In one case a broad stripe was found to coincide with workers being given the day off to view a cock fight A cockfight is a blood sport, held in a ring called a cockpit. The history of raising fowl for fighting goes back 6,000 years. The first documented use of the ''word'' gamecock, denoting use of the cock as to a "game", a sport, pastime or ente .... Breaks of more than a day would produce an even broader stripe such as when Christmas fell on a Monday. The Sunday stone would over time block the drainage pipes necessitating their replacement.

picture info	Sunday Stone At The Natural History Museum Sunday is the day of the week between Saturday and Monday. In most Western countries, Sunday is a day of rest and a part of the Workweek and weekend, weekend. It is often considered the first day of the week. For most observant adherents of Christianity, Sunday is generally observed as a day of worship and rest, recognising it as the ''Lord's Day'' and the day of Christ's resurrection; in the United States, Canada, Japan, the Philippines as well as in most of South America, Sunday is the first day of the week. According to the Hebrew calendar and traditional calendars (including Christian calendars) Sunday is the first day of the week; Quaker Christians call Sunday the "first day" in accordance with their testimony of simplicity.

	Barium Sulfate Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications.Holleman, A. F. and Wiberg, E. (2001) ''Inorganic Chemistry'', San Diego, CA : Academic Press, . Uses Drilling fluids About 80% of the world's barium sulfate production, mostly purified mineral, is consumed as a component of oil well drilling fluid. It increases the density of the fluid, increasing the hydrostatic pressure in the well and reducing the chance of a blowout. Radiocontrast agent Barium sulfate in suspension is often used medically as a radiocontrast agent for X-ray imaging and other diagnostic procedures. It is most often used in imaging of the GI tract during what is colloquially known as a "barium meal". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Cock Fight A cockfight is a blood sport, held in a ring called a cockpit. The history of raising fowl for fighting goes back 6,000 years. The first documented use of the ''word'' gamecock, denoting use of the cock as to a "game", a sport, pastime or entertainment, was recorded in 1634, after the term "cock of the game" used by George Wilson, in the earliest known book on the sport of cockfighting in ''The Commendation of Cocks and Cock Fighting'' in 1607. But it was during Magellan's voyage of discovery of the Philippines in 1521 when modern cockfighting was first witnessed and documented for Westerners by the Italian Antonio Pigafetta, Magellan's chronicler, in the Kingdom of Taytay. The combatants, referred to as gamecocks (not to be confused with game birds), are specially bred and conditioned for increased stamina and strength. Male and female chickens of such a breed are referred to as game fowl. Cocks possess congenital aggression toward all males of the same species. Wagers are ...
