Place of Origin: China Model Number: 002A Motocross Parts & Accessories Alloy Fuel Tank Cover/Gas Cap Color Avialable: gold,silver,black,blue and red Color Avialable:gold,silver,black,blue and red Shagreen is a type of roughened untanned leather, formerly made from a horse's back, or that of an onager (wild ass), and typically dyed green. Shagreen is now commonly made of the skins of sharks and rays. The word derives from the French chagrin which in turn is borrowed from Turkish sa?r? 'the back of a horse'; its roughness later led to the French meaning displeasure or ill-humor.[1]The handle of this tanto (left) has been covered with shagreen in its unpolished, untanned, natural form. Shark and ray leather are a common feature of japanese and Chinese sword handles and scabbards.Shagreen has an unusually rough and granular surface, and is sometimes used as a fancy leather for book bindings, pocket-books and small cases, as well as its more utilitarian uses in the handles of swords and daggers, where slipperiness is a positive disadvantage. In Asia, the Japanese Tachi, Katana, and Wakizashi swords had their hilts almost always covered in undyed untreated Shagreen, while in China shagreen was traditionally used on Qing dynasty composite bows, typically the ears and the spaces above and beneath the grip were covered by polished shagreen (in which the calcified papillae are reduced to equal height and form uniform surface), sometimes with inlay work of different coloured shagreen. Shagreen was a very common cover for 19th century reading glasses containers as well as other utensil boxes from China.An antique round box covered with dyed pearl ray shagreen. Boxes like these where often made in China during the 18/19th centuries, but also in Europe where shagreen came to be known as "galuchat"(France).In particular boxes for glasses where often covered with shagreen.Usually the little pearls where ground down to produce a smooth, but puzzle like surface that would often be dyed green.The early horse skin variety of Shagreen was traditionally prepared by embedding plant seeds (often Chenopodium) in the untreated skin while soft, covering the skin with a cloth, and trampling them into the skin. When the skin was dry the seeds were shaken off, leaving the surface of the leather covered with small indentations. Sources are not clear whether this was being done to imitate pearl ray skin shagreen from East Asia or if it developed on its own.In the 17th and early 18th centuries, however, the term "shagreen" began to be applied to leather made from sharkskin or the skin of a rayfish (probably the pearled ray, Hypolophus sephen). This form is also termed sharkskin or galuchat. Such skins are naturally covered with round, closely set, calcified papillae called placoid scales, whose size is chiefly dependent on the age and size of the animal. These scales are ground down to give a roughened surface of rounded pale protrusions, between which the dye (again, typically green vegetable dye) shows when the material is coloured from the other side. This latter form of shagreen was first popularised in Europe by Jean-Claude Galluchat (d. 1774), a master leatherworker in the court of Louis XV of France. It quickly became a fashion amongst the French aristocracy, and appears to have migrated throughout Europe by the mid-18th century.In medicine, a shagreen patch is a patch of shagreen-like rough skin, often on the lower back, found in some people with the genetic condition tuberous sclerosis.See alsoLa Peau de chagrin Further readingJean Perfettini - Le galuchat (Henri Vial, 1989) ISBN 2-85101-021-2 References^ Oxford English Dictionary, s.v. chagrin and shagreen Categories: Leather Words of Turkish origin(and so on) To get More information , you can visit some products about shoes in stocks, vintage sun glasses, .
