Patent Leather
Patent leather is a type of coated leather that has a high-gloss finish. The coating process was introduced to the United States and improved by inventor Seth Boyden, of Newark, New Jersey, in 1818, with commercial manufacture beginning September 20, 1819. Boyden's process, which he did not patent, used a lacquer coating that was based on linseed oil. Modern patent leather usually has a plastic coating. History In general, patent leather is a fine grain leather that is treated to give it a glossy appearance. An early reference to patent leather is in the 1793 British periodical '' The Bee, or Literary Weekly Intelligencer'', which notes, in an article entitled "Hand's patent leather", that "a gentleman of the name of Hand" in Birmingham, England, obtained a patent for preparing flexible leather having a glaze and polish that renders it impervious to water and need only be wiped with a sponge to restore it to its original luster. In November 1799, inventor Edmund Prior, of H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rufus Porter (painter)
Rufus Porter (May 1, 1792 – August 13, 1884) was an American painter, inventor, and founder of ''Scientific American'' magazine. Famous family Rufus Porter descended from an old colonial New England family. The family's first immigrants to the US were Mary and John Porter (–1676) who emigrated from Dorset, England to Salem, Massachusetts in the early 17th century. When John died in 1676 he was the largest landowner around, owning property that included the modern cities of Salem, Danvers, Wenham, Beverly, Topsfield and Boxford, Massachusetts. Later descendants included Benjamin Porter, who was Rufus' great-grandfather. Benjamin moved to West Boxford in 1716 and became the wealthiest man there. His descendants include ministers, doctors, lawyers, merchants, an army colonel, a ship's captain, a professor of mathematics and several legislative members. He was related by marriage to Henry Wadsworth Longfellow, the Honorable Rufus King (minister to England) and Harri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Leather
Artificial leather, also called synthetic leather, is a material intended to substitute for leather in upholstery, clothing, footwear, and other uses where a leather-like finish is desired but the actual material is cost prohibitive or unsuitable. Artificial leather is known under many names, including ''leatherette'', ''imitation leather'', ''faux leather'', ''vegan leather'', ''PU leather'', and ''pleather''. Manufacture Many different methods for the manufacture of imitation leathers have been developed. A current method is to use an embossed release paper known as ''casting paper'' as a form for the surface finish, often mimicking the texture of top-grain leather. This embossed release paper holds the final texture in negative. For the manufacture, the release paper is coated with several layers of plastic e.g. pvc or polyurethane, possibly including a surface finish, a colour layer, a foam layer, an adhesive, a fabric layer, a reverse finish. Depending on the spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent Leather Shoes
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder m ...

1960s In Western Fashion
In a decade that broke many traditions, adopted new cultures, and launched a new age of social movements, 1960s fashion had a nonconformist but stylish, trendy touch. Around the middle of the decade, new styles started to emerge from small villages and cities into urban centers, receiving media publicity, influencing ''haute couture'' creations of elite designers and the mass-market clothing manufacturers. Examples include the mini skirt, culottes, go-go boots, and more experimental fashions, less often seen on the street, such as curved PVC dresses and other PVC clothes. Mary Quant popularized the not mini skirt, and Jackie Kennedy introduced the pillbox hat; both became extremely popular. False eyelashes were worn by women throughout the 1960s. Hairstyles were a variety of lengths and styles. Psychedelic prints, neon colors, and mismatched patterns were in style. In the early-to-mid 1960s, London "Modernists" known as Mods influenced male fashion in Britain. Designers w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parkesine
Celluloids are a class of materials produced by mixing nitrocellulose and camphor, often with added dyes and other agents. Once much more common for its use as photographic film before the advent of safer methods, celluloid's common contemporary uses are table tennis, table tennis balls, musical instruments, combs, office equipment, and guitar picks. History Nitrocellulose Nitrocellulose-based plastics slightly predate celluloid. Collodion, invented in 1848 and used as a wound dressing and an emulsion for photographic plates, is dried to a celluloid like film. Alexander Parkes The first celluloid as a bulk material for forming objects was made in 1855 in Birmingham, England, by Alexander Parkes, who was never able to see his invention reach full fruition, after his firm went bankrupt due to scale-up costs. Parkes patented his discovery as Parkesine in 1862 after realising a solid residue remained after evaporation of the solvent from photographic collodion. Parkes patented it ...

Tanning (leather)
Tanning is the process of treating skins and hides of animals to produce leather. A tannery is the place where the skins are processed. Tanning hide into leather involves a process which permanently alters the protein structure of skin, making it more durable and less susceptible to decomposition and coloring. Before tanning, the skins are dehaired, degreased, desalted and soaked in water over a period of six hours to two days. Historically this process was considered a noxious or "odoriferous trade" and relegated to the outskirts of town. Historically, tanning used tannin, an acidic chemical compound from which the tanning process draws its name, derived from the bark of certain trees. An alternative method, developed in the 1800s, is chrome tanning, where chromium salts are used instead of natural tannins. History The English word for tanning is from medieval Latin , derivative of ( oak bark), from French (tanbark), from old-Cornish (red oak). These terms are ...

Varnish
Varnish is a clear transparent hard protective coating or film. It is not a stain. It usually has a yellowish shade from the manufacturing process and materials used, but it may also be pigmented as desired, and is sold commercially in various shades. Varnish is primarily used as a wood finish where, stained or not, the distinctive tones and grains in the wood are intended to be visible. Varnish finishes are naturally glossy, but satin/semi-gloss and flat sheens are available. History The word "varnish" comes from Mediaeval Latin ''vernix'', meaning odorous resin, itself derived from Middle Greek ''berōnikón'' or ''beroníkē'', meaning amber or amber-colored glass. A false etymology traces the word to the Greek '' Berenice'', the ancient name of modern Benghazi in Libya, where the first varnishes in the Mediterranean area were supposedly used and where resins from the trees of now-vanished forests were sold. Early varnishes were developed by mixing resin—pine sap, fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turpentine
Turpentine (which is also called spirit of turpentine, oil of turpentine, terebenthene, terebinthine and (colloquially) turps) is a fluid obtained by the distillation of resin harvested from living trees, mainly pines. Mainly used as a specialized solvent, it is also a source of material for organic syntheses. Turpentine is composed of terpenes, primarily the monoterpenes alpha- and beta-pinene, with lesser amounts of carene, camphene, dipentene, and terpinolene.Kent, James A. ''Riegel's Handbook of Industrial Chemistry'' (Eighth Edition) Van Nostrand Reinhold Company (1983) p.569 Mineral turpentine or other petroleum distillates are used to replace turpentine – although the constituent chemicals are very different. Etymology The word ''turpentine'' derives (via French and Latin), from the Greek word τερεβινθίνη ''terebinthine'', in turn the feminine form (to conform to the feminine gender of the Greek word, which means "resin") of an adjective (τ ...

Pumice
Pumice (), called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough-textured volcanic glass, which may or may not contain crystals. It is typically light-colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker vesicle walls, and being dark colored and denser.Jackson, J.A., J. Mehl, and K. Neuendorf (2005) ''Glossary of Geology'' American Geological Institute, Alexandria, Virginia. 800 pp. McPhie, J., M. Doyle, and R. Allen (1993) ''Volcanic Textures A guide to the interpretation of textures in volcanic rocks'' Centre for Ore Deposit and Exploration Studies, University of Tasmania, Hobart, Tasmania..198 pp. Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solu ...

Lampblack
Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal and coal tar, vegetable matter, or petroleum products, including fuel oil, fluid catalytic cracking tar, and ethylene cracking. Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) polycyclic aromatic hydrocarbon (PAH) content. However, carbon black can be used as a model compound for diesel soot to better understand how diesel soot behaves under various reaction conditions as carbon black and diesel soot have some similar properties such as particle sizes, densities, and copolymer adsorption abilities that contribute to them having similar behaviours under various reactions such as oxidation experiment ...
