Factory Mark
A factory mark is a symbolic marking affixed by manufacturers on their productions in order to authenticate them. Numerous factory marks are known throughout the ages, and are essential in determining the provenance or dating of productions. Porcelain Factory marks are essential in the area of porcelain production especially, where they are sometimes also called "backstamps", and where their absence would make authentication much more difficult.

Porcelain
Porcelain () is a ceramic material made by heating substances, generally including materials such as kaolinite, in a kiln to temperatures between . The strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste, and bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions. Porcelain slowly evolved in China and was finally achieved (depending on the definition used) at some point about 2,000 to 1,200 years ago; it slowly spread to other East Asian countries, then to Europe, and eventually to the rest of the world. Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, and it ...

Meissen Porcelain
Meissen porcelain or Meissen china was the first European hard-paste porcelain. Early experiments were done in 1708 by Ehrenfried Walther von Tschirnhaus. After his death that October, Johann Friedrich Böttger continued von Tschirnhaus's work and brought this type of porcelain to the market, financed by King Augustus II of Poland, Augustus the Strong, King of Poland and Elector of Saxony. The production of porcelain in the royal factory at Meissen, near Dresden, started in 1710 and attracted artists and artisans to establish, arguably, the most famous porcelain manufacturer known throughout the world. Its signature logo, the crossed swords, was introduced in 1720 to protect its production; the mark of the swords is reportedly one of the oldest trademarks in existence. ''Dresden porcelain'' (or "china") was once the usual term for these wares, until in 1975 the (Higher Munich State Court) decided in favour of the Saxon Porcelain Manufactory Dresden, which alone was then allowed ...

Builder's Signature
A builder's signature, sometimes known as a craftsman's signature, tradesman's signature, or workman's signature, is a type of signature associated with several skilled trades in which a tradesperson inscribes their name on a structure during or after completion of a project. In some instances, the signature may be hidden from public view, such as a signature inscribed on wooden framing which is subsequently covered with drywall; in other instances the signature may be prominently displayed such as in concrete. Historic examples Several notable architects and carpenters throughout history are known to have employed builder's signatures on the structures they built. Frank Lloyd Wright was known to place a red square tile on buildings he designed; on six occasions, Wright signed his name inside these square tiles. Thomas de Monchaux has written that "in 1950, Wright commissioned ceramicist Jeanette Pauson Haber, to make some 25 red tiles inscribed with his initials, that were, in a ...

Hallmark
A hallmark is an official mark or series of marks struck on items made of metal, mostly to certify the content of noble metals—such as platinum, gold, silver and in some nations, palladium. In a more general sense, the term ''hallmark'' can also be used to refer to any distinguishing mark. General overview Historically, hallmarks were applied by a trusted party: the "guardians of the craft" or, more recently, by an assay office. Hallmarks are a guarantee of certain purity or fineness of the metal, as determined by official metal (assay) testing. Distinguishment Hallmarks are often confused with "trademarks" or "maker's marks". A hallmark is not the mark of a manufacturer to distinguish their products from other manufacturers' products: that is the function of trademarks or makers' marks. To be a true hallmark, it must be the guarantee of an independent body or authority that the contents are as marked. Thus, a stamp of "925" by itself is not, strictly speaking, a hallmark, b ...

House Mark
A house mark was originally a mark of property, later also used as a family or clan emblem, incised on the facade of a building, on animals, in signet and similar in the farmer and burgher culture of Germany and Scandinavia. These marks have the appearance of glyphs or runes consisting of a pattern of simple lines, without the application of colour. Description The form of house marks is based on function. They should be easy to cut, scratch or engrave with a knife or similar tool. At the same time, they should be distinctive and easy to remember. House marks differ from the more complicated patterns of a coat of arms or flags, which include surfaces and solid colors. House marks can be made from one or two lines and up to quite a complex pattern of line figures. Based on appearance, house marks resemble line figures in rock carvings and in early writing systems. It is unclear how extensively such ancient line figures were used as marks for people or property ownership. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mason's Mark
A mason's mark is an engraved symbol often found on dressed stone in buildings and other public structures. In stonemasonry Regulations issued in Scotland in 1598 by James VI's Master of Works, William Schaw, stated that on admission to the guild, every mason had to enter his name and his mark in a register. There are three types of marks used by stonemasons. *Banker marks were made on stones before they were sent to be used by the walling masons. These marks served to identify the banker mason who had prepared the stones to their paymaster. This system was employed only when the stone was paid for by measure, rather than by time worked. For example, the 1306 contract between Richard of Stow, mason, and the Dean and Chapter of Lincoln Cathedral, specified that the plain walling would be paid for by measure, and indeed banker marks are found on the blocks of walling in this cathedral. Conversely, the masons responsible for walling the eastern parts of Exeter Cathedral were paid b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merchant's Mark
A merchant's mark is an emblem or device adopted by a merchant, and placed on goods or products sold by him in order to keep track of them, or as a sign of authentication. It may also be used as a mark of identity in other contexts. History Ancient use Merchants' marks are as old as the sealings of the third millennium BCE found in Sumer that originated in the Indus Valley. Impressions of cloth, strings and other packing material on the reverse of tags with seal impressions indicate that the Harappan seals were used to control economic administration and trade. Amphorae from the Roman Empire can sometimes be traced to their sources from the inscriptions on their handles. Commercial inscriptions in Latin, known as tituli picti, appear on Roman containers used for trade. Middle ages and early modern period Symbolic merchants' marks continued to be used by artisans and townspeople of the medieval and early modern eras to identify themselves and authenticate their goods.

Printer's Mark
A printer's mark, device, emblem or insignia is a symbol that was used as a trademark by early printers starting in the 15th century. The first printer's mark is found in the 1457 Mainz Psalter by Johann Fust and Peter Schöffer. One of the most well-known old printer's marks is the dolphin and anchor, first used by the Venetian printer Aldus Manutius as his mark in 1502. The database Printers' Devices of the Ancient Book Section of the Library of the University of Barcelona, was launched in October 1998. The University of Florida libraries also provide digital access to printers' devices and include The University of Chicago devices that have appeared on the cover of their publication ''The Library Quarterly''. Printers' devices have been incorporated in American library buildings, as a reflection of the British Arts and Crafts Movement.Karen Nipps, "Printers' Devices as Decorative Elements in Library Architecture."
