Potter's Mark
A factory mark is a 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. History The manufacturer's marks are very old: the ones found on Korakou culture pottery are four thousand years old, and the ones on ancient Greek and Roman vases date back to 5th-4th centuries BC. While the production marks are technically distinct from the ownership marks, at these times, when a craftsman typically was the same person as the merchant, and many people were illiterate, a single mark frequently served both purposes. Medieval gilds set up the system of compulsory ("regulatory") marks for the craftsman, intended to trace the defective items and punish the offenders, with most typical examples provided by the bakery trade. In English weapons manufacturing (including cutlery) the regulations concerning the manufacturer marks were fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Certification Mark
A certification mark on a commercial product or service is a registered Mark (sign), mark that enables its owner ("certification body") to certify that the goods or services of a particular provider (who is not the owner of the certification mark) have particular properties, e.g., regional or other origin, material, quality, accuracy, mode of manufacture, being produced by Trade union, union labor, etc. The standards to which the product is held are stipulated by the owner of the certification mark. There are essentially three general types of certification marks: # certifying that goods or services had originated in a particular geographic region (e.g., Roquefort cheese); # certifying that goods or services meet particular standards for quality, materials, methods of manufacturing, for example, tests by the Underwriter Laboratories; # certifying that the manufacturer has met certain standards or belong to a certain organization or union (e.g.,BIS Certification in clothing). ...

Tang Mark
A tang or shank is the back portion of the blade component of a tool where it extends into stock material or connects to a handle – as on a knife, sword, spear, arrowhead, chisel, file, coulter, pike, scythe, screwdriver, etc. One can classify various tang designs by their appearance, by the manner in which they attach to a handle, and by their length in relation to the handle. ''Nakago'' is the term in Japanese, used especially when referring to the tang of the katana or the wakizashi. Full vs partial tang A full tang extends the full length of the grip-portion of a handle, versus a ''partial'' tang which does not. A full tang may or may not be as wide as the handle itself, but will still run the full length of the handle. There are a wide variety of full and partial tang designs. In perhaps the most common design in full tang knives, the handle is cut in the shape of the tang and handle scales are then fastened to the tang by means of pins, screws, bolts, metal tubin ...

Printer's Mark
A printer's mark, Heraldic badge, device, emblem or insignia is a symbol that was used as a trademark by early Printer (publishing), 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 Venice, Venetian printer Aldus Manutius as his mark in 1502. The Library of the University of Barcelona launched a database of Printers' Devices in the ancient book section 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, reflecting the British Arts and Crafts Movement. From 1931 to 2012, Library Quarterly featured 328 printers' marks with an article on the history of each mark. ... [...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 Titulus pictus, 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 ...

Mason's Mark
A mason's mark is an engraved symbol often found on dressed Rock (geology), stone in buildings and other public structures. In stonemasonry Regulations issued in Scotland in 1598 by James VI and I, James VI's Master of Works, William Schaw, stated that on admission to the guild, every Masonry, mason had to enter his name and his mark in a register. There are three types of marks used by Stonemasonry, 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 for 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 wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, the Netherlands and the Nordic countries. 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 peopl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Medici Porcelain
Medici porcelain was the first successful attempt in Europe to make imitations of Chinese porcelain, though it was soft-paste porcelain rather than the hard-paste made in Asia. The experimental manufactory housed in the Casino of San Marco in Florence existed between 1575 and 1587 under the patronage of Francesco I de' Medici, Grand Duke of Tuscany. Surviving examples are extremely rare, numbering 59 according to the Metropolitan Museum of Art. A painted mark of Brunelleschi's dome and a capital letter F appear on the underside of some pieces; others bear the Medici ''palle'', the balls that are the Medici heraldic charge. Never a commercial venture, Medici porcelains were sometimes given as diplomatic gifts; for example, surviving pieces bear the arms of Philip II of Spain. In 1995, a vase dated to around 1575, was sold in Paris for FRF6,430,000 (at the time equivalent to £870,000). In 1999, a cruet dated circa 1575 was auctioned at Christie's for £287,000.

Saint-Cloud Porcelain
Saint-Cloud porcelain was a type of soft-paste porcelain produced in the French town of Saint-Cloud from the late 17th to the mid 18th century. Foundation In 1702, Philippe I, Duke of Orléans gave letters-patent to the family of Pierre Chicaneau, who were said to have been making porcelain as "perfect as the Chinese" since 1693. Chicaneau's factory was a pioneer in the manufacture of porcelain in Europe, where there had been many attempts to copy Chinese porcelain. Saint-Cloud developed a frit ("a mixture of a flux, sand and chalk") which was close, although not similar, to Asian porcelain. Blue-and-white porcelain The porcelain produced in Saint-Cloud was influenced by late Ming blue and white porcelain and its motifs were based on Chinese originals. The typical underglaze blue painted Saint-Cloud porcelain, says W.B. Honey, "is one of the most distinct and attractive of porcelains, and not the least part of its charm lies in the quality of the material itself. It is rarely ...

Meissen Porcelain
Meissen porcelain or Meissen china was the first Europe, 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 a ...

Porcelain
Porcelain (), also called china, is a ceramic material made by heating Industrial mineral, raw materials, generally including kaolinite, in a kiln to temperatures between . The greater strength and translucence of porcelain, relative to other types of pottery, arise mainly from Vitrification#Ceramics, vitrification and the formation of the mineral mullite within the body at these high temperatures. End applications include tableware, ceramic art, decorative ware such as figurines, and products in technology and industry such as Insulator (electricity), electrical insulators and laboratory ware. The manufacturing process used for porcelain is similar to that used for earthenware and stoneware, the two other main types of pottery, although it can be more challenging to produce. It has usually been regarded as the most prestigious type of pottery due to its delicacy, strength, and high degree of whiteness. It is frequently both glazed and decorated.
