Guilloché
Guilloché (; or guilloche) is a decorative technique in which a very precise, intricate and repetitive pattern is mechanically engraved into an underlying material via engine turning, which uses a machine of the same name, also called a rose engine lathe. This mechanical technique improved on more time-consuming designs achieved by hand and allowed for greater delicacy, precision, and closeness of line, as well as greater speed. The term ''guilloche'' is also used more generally for repetitive architectural patterns of intersecting or overlapping spirals or other shapes, as used in the Ancient Near East, classical Greece and Rome and neo-classical architecture, and Early Medieval interlace decoration in Anglo-Saxon art and elsewhere. Medieval Cosmatesque stone inlay designs with two ribbons winding around a series of regular central points are very often called guilloche. These central points are often blank, but may contain a figure, such as a rose. These senses are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine Turning
Engine turning, also known as jewelling, is a fine geometric pattern turned onto metal as a finish. Aluminium is often the metal chosen to inscribe, but any appropriate surface can be finely machined to produce intricate repetitive patterns that offer reflective interest and fine detail. Uses Aircraft '' Perlée''-style engine turning was used on the sheetmetal panels of the engine cowling (nose) of Charles Lindbergh's aircraft, the '' Spirit of St. Louis''. The sheet metal parts of the World War I Fokker Eindecker fighter aircraft series, especially around the engine cowl and associated sheetmetal, are noted for having a "dragged" form of engine turning entirely covering them. The tool creating the "swirls" was repeatedly moved along a short irregular path each time while pressed against the metal, to create the intricate appearance that was characteristic of the aircraft's sheet-metal parts. It is partly surmised to have been a mechanical method to "clad" a duralumin-allo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rose Engine Lathe
A rose engine lathe is a specialized kind of geometric lathe. The head stock rocks back and forth with a rocking motion and/or slides along the spindle axis in a pumping motion. A rosette or cam-like pattern mounted on the spindle is controlled by moving against a cam follower(s) while the lathe spindle rotates. Rose engine work can make flower patterns, as well as convoluted, symmetrical, multi-lobed geometric patterns. The patterns it produces are similar to that of a Spirograph, in metal. No other ornamental lathe can produce these "rose" patterns. The decoration produced by a rose engine lathe is called guilloche. It sometimes confused with "jewel finishes" or engine turning, a much cheaper process of making swirly marks in metal by a rotating abrasive peg or pad, which is repeatedly applied to the surface to make a pattern of overlapping circles. Jewel finishes used to be common on stereo faceplates and automobile interiors. The patterns of United Kingdom's first postag ...

Counterfeit
To counterfeit means to imitate something authentic, with the intent to steal, destroy, or replace the original, for use in illegal transactions, or otherwise to deceive individuals into believing that the fake is of equal or greater value than the real thing. Counterfeit products are fakes or unauthorized replicas of the real product. Counterfeit products are often produced with the intent to take advantage of the superior value of the imitated product. The word ''counterfeit'' frequently describes both the forgeries of currency and documents as well as the imitations of items such as clothing, handbags, shoes, pharmaceuticals, automobile parts, unapproved aircraft parts (which have caused many accidents), watches, electronics The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bank Note
A banknote—also called a bill (North American English), paper money, or simply a note—is a type of negotiable promissory note, made by a bank or other licensed authority, payable to the bearer on demand. Banknotes were originally issued by commercial banks, which were legally required to redeem the notes for legal tender (usually gold or silver coin) when presented to the chief cashier of the originating bank. These commercial banknotes only traded at face value in the market served by the issuing bank. Commercial banknotes have primarily been replaced by national banknotes issued by central banks or monetary authorities. National banknotes are often – but not always – legal tender, meaning that courts of law are required to recognize them as satisfactory payment of money debts. Historically, banks sought to ensure that they could always pay customers in coins when they presented banknotes for payment. This practice of "backing" notes with something of substance i ...

Peter Carl Fabergé
Peter Carl Fabergé, also known as Karl Gustavovich Fabergé (russian: Карл Гу́ставович Фаберже́, ''Karl Gustavovich Faberzhe''; 30 May 1846 – 24 September 1920), was a Russian jeweller best known for the famous Fabergé eggs made in the style of genuine Easter eggs, but using precious metals and gemstones rather than more mundane materials. He was one of the sons of the founder of the famous jewelry legacy House of Fabergé. Early life Faberge was born in Saint Petersburg, Russia, to the Baltic German jeweller Gustav Fabergé and his German wife Charlotte Jungstedt, the daughter of Katarina Augusta Hertig and Karl Jungstedt. Gustav Fabergé's paternal ancestors were Huguenots, originally from La Bouteille, Picardy, who fled from France after the revocation of the Edict of Nantes, first to Germany near Berlin, then in 1800 to the Pernau (today Pärnu) Baltic province of Livonia, then part of Russia, now Estonia. Until he was 14 years old he went to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitreous Enamel
Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between . The powder melts, flows, and then hardens to a smooth, durable vitreous coating. The word comes from the Latin , meaning "glass". Enamel can be used on metal, glass, ceramics, stone, or any material that will withstand the fusing temperature. In technical terms fired enamelware is an integrated layered composite of glass and another material (or more glass). The term "enamel" is most often restricted to work on metal, which is the subject of this article. Essentially the same technique used with other bases is known by different terms: on glass as '' enamelled glass'', or "painted glass", and on pottery it is called '' overglaze decoration'', "overglaze enamels" or "enamelling". The craft is called "enamelling", the artists "enamellers" and the objects produced can be called "enamels". Enamelling is an old and widely adopted technology, for ...

Lady Randolph Spencer Churchill
Jennie Spencer-Churchill (; 9 January 1854 – 29 June 1921), known as Lady Randolph Churchill, was an American-born British socialite, the wife of Lord Randolph Churchill, and the mother of British prime minister Sir Winston Churchill. Early life Jennie Jerome was born in the Cobble Hill section of Brooklyn in 1854, the second of four daughters (one died in childhood) of financier, sportsman, and speculator Leonard Jerome and his wife Clarissa (always called Clara), daughter of Ambrose Hall, a landowner. Jerome's father was of Huguenot extraction, his forebears having emigrated to America from the Isle of Wight in 1710. Hall family lore insists that Jennie had Iroquois ancestry through her maternal grandmother; however, there is no research or evidence to corroborate this. She was raised in Brooklyn, Paris, and New York City. She had two surviving sisters, Clarita (1851–1935) and Leonie (1859–1943). Another sister, Camille (1855–1863) died when Jennie was nine.

William Dwight Whitney
William Dwight Whitney (February 9, 1827June 7, 1894) was an American linguist, philologist, and lexicographer known for his work on Sanskrit grammar and Vedic philology as well as his influential view of language as a social institution. He was the first president of the American Philological Association and editor-in-chief of ''The Century Dictionary''. Life William Dwight Whitney was born in Northampton, Massachusetts on February 9, 1827. His father was Josiah Dwight Whitney (1786–1869) of the New England Dwight family.

The Century Dictionary
''The Century Dictionary and Cyclopedia'' is one of the largest encyclopedic dictionaries of the English language. In its day it was compared favorably with the ''Oxford English Dictionary,'' and frequently consulted for more factual information than would normally be the case for a dictionary. History The ''Century Dictionary'' is based on ''The Imperial Dictionary of the English Language'', edited by Rev. John Ogilvie (1797–1867) and published by W. G. Blackie and Co. of Scotland, 1847–1850, which in turn is an expansion of the 1841 second edition of Noah Webster's ''American Dictionary''. In 1882 The Century Company of New York bought the American rights to ''The Imperial Dictionary'' from Blackie and Son. The first edition of the ''Century Dictionary'' was published from 1889 to 1891 by The Century Company, and was described as "six volumes in twenty four". The first edition runs to 7,046 pages and features some 10,000 wood-engraved illustrations. It was edited by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
