Reticulation (metalwork)
In metalwork, reticulation refers to a decorative surface finishing technique involving the application of localised heat to the surface of a metal object. Reticulation is typically performed on alloys of silver and copper or of gold and copper. Reticulation exploits the difference between the melting temperature of an unalloyed metal and that of an alloy of the metal; by depleting the base metal A base metal is a common and inexpensive metal, as opposed to a precious metal such as gold or silver. In numismatics, coins often derived their value from the precious metal content; however, base metals have also been used in coins in the past ... content in the surface layer, a piece can be heated in such a manner so as to render the interior of the piece molten while leaving the surface of the piece intact. The reticulated surface is formed by the thermal expansion and contraction of the interior metal which is effected by deliberate variation in the application of localised heat. ...

Reticulated Silver - Samorodok (7217992534)
Reticulation is a net-like pattern, arrangement, or structure. Reticulation or Reticulated may refer to: * Reticulation (single-access key), a structure of an identification tree, where there are several possible routes to a correct identification * A coloration pattern of some animals (e.g. the reticulated giraffe) * An arrangement of veins in a leaf, with the veins interconnected like a network * The endoplasmic reticulum within a cell, often resembling a net * A phylogenetic network, the result when hybrid speciation, introgression and paraphyletic speciation is applied to a phylogenetic tree * Reticulated water (Australia, South Africa), water from a piped network rather than from a bore or well, see: wiktionary:reticulated water *Reticulation (metalwork) In metalwork, reticulation refers to a decorative surface finishing technique involving the application of localised heat to the surface of a metal object.

Surface Finishing
Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. Finishing processes may be employed to: improve product appearance, adhesion or wettability, solderability, corrosion resistance, tarnish resistance, the chemical resistance, the wear resistance, hardness, modify electrical conductivity, remove burrs and other surface flaws, and control the surface friction.. In limited cases some of these techniques can be used to restore original dimensions to salvage or repair an item. An unfinished surface is often called '' mill finish''. These processes can improve the durability, performance and even the appearance of the surface being finished. Surface finishing is often one of the final steps taken when working metal and is essential for guaranteeing that metal components meet the requirements of the necessary finish. Surface finishing processes can be categorized by how they affect the workpiece: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Base Metal
A base metal is a common and inexpensive metal, as opposed to a precious metal such as gold or silver. In numismatics, coins often derived their value from the precious metal content; however, base metals have also been used in coins in the past and today. Specific definitions In contrast to noble metals, base metals may be distinguished by oxidizing or corroding relatively easily and reacting variably with diluted hydrochloric acid (HCl) to form hydrogen. Examples include iron, nickel, lead and zinc. Copper is also considered a base metal because it oxidizes relatively easily, although it does not react with HCl. In mining and economics, the term base metals refers to industrial non-ferrous metals excluding precious metals. These include copper, lead, nickel and zinc. The U.S. Customs and Border Protection agency is more inclusive in its definition of commercial base metals. Its list includes—in addition to copper, lead, nickel, and zinc—the following metals: iron and ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
House Of Fabergé
The House of Fabergé (; ) was a jewellery firm founded in 1842 in Saint Petersburg, Russia, by Gustav Fabergé, using the accented name ''Fabergé''. Gustav's sons Peter Carl and Agathonand grandsons followed him in running the business until the October Revolution in 1917. The firm was famous for designing elaborate jewel-encrusted Fabergé eggs for Russian emperors, and for a range of other work of high quality and intricate detail. In 1924, Peter Carl's sons Alexander and Eugène Fabergé opened a firm called Fabergé & Cie in Paris, France, making similar jewellery items and adding the name of the city to their firm's stamp, styling it ''FABERGÉ, PARIS''. In 1951, rights to the Fabergé brand name for the marketing of perfume were bought by Samuel Rubin. In 1964, Rubin sold his Fabergé Inc. company to cosmetics firm Rayette Inc., which changed its name to Rayette-Fabergé Inc. As the brand was resold more times, companies using the Fabergé name launched clothing lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
