Must Weight
Must weight is a measure of the amount of sugar in grape juice (must) and, hence, indicates the amount of ethanol, alcohol that could be produced if it is all fermentation (wine), fermented to alcohol, rather than left as residual sugar. , accessed on March 26, 2009 Measurement is in degrees In France and many other countries, the grape must density is often recalculated to show potential alcohol, the percent alcohol content that would be the result if the must were fermented to a completely dry wine, which also applies to fermented water.Refractometer scales * Brix (°Bx): Used in Italy, France, and Canada. * Klosterneuburger Mostwaage (KMW): Used in Austria. The scale is divided into Klosterneuburger Zuck ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxyhydrogen
Oxyhydrogen is a mixture of hydrogen (H2) and oxygen (O2) gases. This gaseous mixture is used for torches to process refractory materials and was the first gaseous mixture used for welding. Theoretically, a ratio of 2:1 hydrogen:oxygen is enough to achieve maximum efficiency; in practice a ratio 4:1 or 5:1 is needed to avoid an oxidizing flame. This mixture may also be referred to as ' (Scandinavian and German Knallgas: "bang-gas"), although some authors define knallgas to be a generic term for the mixture of fuel with the precise amount of oxygen required for complete combustion, thus 2:1 oxyhydrogen would be called "hydrogen-knallgas". "Brown's gas" and HHO are terms for oxyhydrogen mainly encountered in fringe science. Properties Oxyhydrogen will combust when brought to its autoignition temperature. For the stoichiometric mixture, 2:1 hydrogen:oxygen, at normal atmospheric pressure, autoignition occurs at about 570 °C (1065 °F). The minimum energy required t ...

19th-century German Inventors
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Freudenstadt (district)
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

Auslese
''Auslese'' (literal meaning: "selected harvest"; plural form is ''Auslesen'') is a German language wine term for a late harvest wine and is a riper category than Spätlese in the '' Prädikatswein'' category of the Austrian and German wine classification. The grapes are picked from selected very ripe bunches in the autumn (late November-early December), and have to be hand-picked. Generally Auslese wine can be made in only the best harvest years that have been sufficiently warm. A small proportion of the grapes may be affected by noble rot in some regions although this never dominates the character of the wine. Rheingau winemaker Schloss Johannisberg is generally credited with discovering Auslese wine in 1787. Auslesen are sometimes considered a German dessert wine, especially the wines made from botrytis infected bunches, though it is not as sweet as Eiswein, Beerenauslese (BA), or Trockenbeerenauslese (TBA) dessert wines. Auslesen can be enjoyed by themselves (''aperitif'' â ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spätlese
Spätlese (literal meaning: "late harvest"; plural form is ''Spätlesen'') is a German wine term for a wine from fully ripe grapes, the lightest of the late harvest wines. Spätlese is a riper category than Kabinett in the '' Prädikatswein'' category of the German wine classification and is the lowest level of ''Prädikatswein'' in Austria, where Kabinett is classified in another way.Wines from Austria: Quality Designations in Detail , accessed on May 19, 2008 In both cases, Spätlese is below in terms of ripeness. The grapes are picked at least seven days after normal har ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilding
Gilding is a decorative technique for applying a very thin coating of gold over solid surfaces such as metal (most common), wood, porcelain, or stone. A gilded object is also described as "gilt". Where metal is gilded, the metal below was traditionally silver in the West, to make silver-gilt (or ''vermeil'') objects, but gilt-bronze is commonly used in China, and also called ormolu if it is Western. Methods of gilding include hand application and gluing, typically of gold leaf, chemical gilding, and electroplating, the last also called gold plating. Parcel-gilt (partial gilt) objects are only gilded over part of their surfaces. This may mean that all of the inside, and none of the outside, of a chalice or similar vessel is gilded, or that patterns or images are made up by using a combination of gilt and ungilted areas. Gilding gives an object a gold appearance at a fraction of the cost of creating a solid gold object. In addition, a solid gold piece would often be too soft or ...

Nickel Silver
Nickel silver, Maillechort, German silver, Argentan, new silver, nickel brass, albata, alpacca, is a copper alloy with nickel and often zinc. The usual formulation is 60% copper, 20% nickel and 20% zinc. Nickel silver does not contain the element silver. It is named for its silvery appearance, which can make it attractive as a cheaper and more durable substitute. It is also well suited for being plated with silver. A naturally occurring ore composition in China was smelted into the alloy known as or () ("white copper" or cupronickel). The name "German Silver" refers to the artificial recreation of the natural ore composition by German metallurgists.Joseph Needham, Ling Wang, Gwei-Djen Lu, Tsuen-hsuin Tsien, Dieter Kuhn, Peter J Golas''Science and civilisation in China'' Cambridge University Press: 1974, , pp. 237–250 All modern, commercially important, nickel silvers (such as those standardized under ASTM B122) contain significant amounts of zinc and are sometimes considered ...

Hydrometer
A hydrometer or lactometer is an instrument used for measuring density or relative density of liquids based on the concept of buoyancy. They are typically calibrated and graduated with one or more scales such as specific gravity. A hydrometer usually consists of a sealed hollow glass tube with a wider bottom portion for buoyancy, a ballast such as lead or mercury for stability, and a narrow stem with graduations for measuring. The liquid to test is poured into a tall container, often a graduated cylinder, and the hydrometer is gently lowered into the liquid until it floats freely. The point at which the surface of the liquid touches the stem of the hydrometer correlates to relative density. Hydrometers can contain any number of scales along the stem corresponding to properties correlating to the density. Hydrometers are calibrated for different uses, such as a lactometer for measuring the density (creaminess) of milk, a saccharometer for measuring the density of sugar in a liqu ...

Pforzheim
Pforzheim () is a city of over 125,000 inhabitants in the federal state of Baden-Württemberg, in the southwest of Germany. It is known for its jewelry and watch-making industry, and as such has gained the nickname "Goldstadt" ("Golden City"). With an area of , it is situated between the cities of Stuttgart and Karlsruhe at the confluence of three rivers (Enz, Nagold and Würm). It marks the frontier between Baden and Württemberg, being located on Baden territory. From 1535-65, it was the home to the Margraves of Baden-Pforzheim. The City of Pforzheim does not belong to any administrative district (''Kreis''), although it hosts the administrative offices of the Enz district that surrounds the town. During World War II, Pforzheim was bombed by the Allies a number of times. The largest raid, and one of the most devastating area bombardments of World War II, was carried out by the Royal Air Force (RAF) on the evening of 23 February 1945.
