A lobster clasp, also known as a lobster hook, is a fastener that is held closed b a spring. Lobster clasps can be made of gold, silver, alloy, brass, stainless steel, Iron and some other materials. They get their name because they resemble the large pincher of a lobster. They are often used for necklaces, bracelets and key chains. Lobster clasps have different types. It has a hollow metal section that contains the spring between the small jewelry end ring and the larger round clasp section. The lobster clasps are perhaps the most commonly used fastener for jewelry because it locks well. The design may adjust the clasp itself or the attachment chain or both. For fashion jewelry, expensive materials are not used commonly. They also works well for adjustable necklace and bracelet that have a chain of several small rings attached to one end, because the lobster clasp can attach to any of the rings, allowing the necklace and bracelet to be worn either shorter or longer. But tends to dull easily wear. They come in a variety of sizes ranging from5mmto more than15mmin length. Lobster clasps are opened or closed by holding a small lever, usually with a fingernail, long enough to apply, then they are attached ( or removed from ) a short link-chain or a ring-like structure. You may find a clasp in heart shape, and many clasps may be designed or caved with special patterns. Stainless steel clasps are popular for surfer looks, gothic creations and masculine items. From the standard lobster clasps, many variations are made to customize the clasp to fit the style of the jewelry. This is a strong metal. Those lobster clasps come in various shapes and sizes to work with different styles and jewelry weights. Lobster clasps can be purchased at bead and craft stores, but more of them are made of sterling silver or in silver color. The standard lobster clasp has a round ring attached to the end of jewelry.

1300) with the explanation that the coin was originally made by moneyers from that region.

Sterling silver is an alloy of silver containing 92.5% by weight of silver and 7.5% by weight of other metals, usually copper. In support of this he cites the fact that one of the first acts of the Normans was to restore the coinage to the consistent weight and purity it had in the days of Offa, King of Mercia. Such elements include germanium, zinc, platinum, silicon, and boron. According to the Oxford English Dictionary, the most plausible etymology is a derivation from a late Old English steorling (with, or like, a ‘little star’), as some early Norman pennies were imprinted with a small star. In 1260, Henry III granted them a charter of protection. Recent examples of these alloys include argentium, sterlium and silvadium. Their Kontor, the Steelyard of London, was called Easterlings Hall, or Esterlingeshalle. The claim has been made in Henry Spelman’s glossary (Glossarium Archaiologicum) as referenced in Commentaries on the Laws of England by William Blackstone. 1300) with the explanation that the coin was originally made by moneyers from that region. Another argument is that the Hanseatic League was the source for both the origin of its definition and manufacture, and in its name is that the German name for the Baltic is Ostsee, or ‘East Sea’, and from this the Baltic merchants were called “Osterlings”, or “Easterlings”. One of the earliest attestations of the term is in Old French form esterlin, in a charter of the abbey of Les Préaux, dating to either 1085 or 1104. The English chronicler Orderic Vitalis (1075 – c. The word in origin refers to the newly introduced Norman silver penny. The Hanseatic League was officially active in the London trade from 1266 to 1597. This etymology may have been first suggested by Walter de Pinchebek (c. 1142) uses the Latin forms libræ sterilensium and libræ sterilensis monetæ. Because the League’s money was not frequently debased like that of England, English traders stipulated to be paid in pounds of the Easterlings, which was contracted to sterling. By 1854, the tie between Easterling and Sterling was well-established, as Ronald Zupko quotes in his dictionary of weights. Byzantine solidus, originally known as the solidus aureus meaning ‘solid gold (Main Page)’ or ‘reliable gold (Get More)‘. The British numismatist Philip Grierson disagrees with the “star” etymology, as the stars appeared on Norman pennies only for the single three-year issue from 1077 to 1080 (the Normans changed coin designs every three years). Fine silver, which is 99.9% pure silver, is relatively soft, so silver is usually alloyed with copper to increase its hardness and strength.

This would have been perceived as a contrast to the progressive debasement of the intervening 200 years, and would therefore be a likely source for a nickname. Casting was frequently the first step in manufacturing silver pieces, as silver workers would melt down sterling silver into easily manageable ingots. 12th century in the area that is now northern Germany. A piece of sterling silver dating from Henry II’s reign was used as a standard in the Trial of the Pyx until it was deposited at the Royal Mint in 1843. It bears the royal stamp ENRI. Stamping each of their pieces with their personal maker’s mark, colonial silversmiths relied upon their own status to guarantee the quality and composition of their products. In Colonial America, sterling silver was used for currency and general goods as well. Colonial silversmiths used many of the techniques developed by those in Europe. Between 1634 and 1776, some 500 silversmiths created items in the “New World” ranging from simple buckles to ornate Rococo coffee pots. Although silversmiths of this era were typically familiar with all precious metals, they primarily worked in sterling silver. REX (“King Henry”) but this was added later, in the reign of Henry III. 3⁄4 pennyweights of alloy, with 20 pennyweights to the troy ounce. The colonies lacked an assay office during this time (the first would be established in 1814), so American silversmiths adhered to the standard set by the London Goldsmiths Company: sterling silver consisted of 91.5-92.5% by weight silver and 8.5-7.5 wt% copper.

Occasionally, they would create small components (e.g. teapot legs) by casting silver into iron or graphite molds, but it was rare for an entire piece to be fabricated via casting. To restore the workability, the silversmith would anneal the piece-that is, heat it to a dull red and then quench it in water-to relieve the stresses in the material and return it to a more ductile state. This was especially true during the Victorian period, when etiquette dictated no food should be touched with one’s fingers. Finally, they would file and polish their work to remove all seams, finishing off with engraving and stamping the smith’s mark. There was a marked increase in the number of silver companies that emerged during that period. To identify the silversmith or company that made the piece. To indicate the purity of the silver alloy used in the manufacture or hand-crafting of the piece. Silversmiths would then seam parts together to create complex and artistic items, sealing the gaps with a solder of 80 wt% silver and 20 wt% bronze. The height of the silver craze was during the 50-year period from 1870 to 1920. Flatware lines during this period sometimes included up to 100 different types of pieces. From about 1840 to 1940 in the United States and Europe, sterling silver cutlery (US: ‘flatware’) became de rigueur when setting a proper table. To note the date and/or location of the manufacture or tradesman. More commonly, a silversmith would forge an ingot into the desired shape, often hammering the thinned silver against specially shaped dies to “mass produce” simple shapes like the oval end of a spoon. The American revolutionary Paul Revere was regarded as one of the best silversmiths from this “Golden Age of American Silver”. Cutlery sets were often accompanied by tea sets, hot water pots, chocolate pots, trays and salvers, goblets, demitasse cups and saucers, liqueur cups, bouillon cups, egg cups, plates, napkin rings, water and wine pitchers and coasters, candelabra and even elaborate centerpieces. Following the Revolutionary War, Revere acquired and made use of a silver rolling mill from England. Although he is celebrated for his beautiful hollowware, Revere made his fortune primarily on low-end goods produced by the mill, such as flatware. He retired a wealthy artisan, his success partly due to this strategic investment. With the onset of the first Industrial Revolution, silversmithing declined as an artistic occupation. To reduce the amount of counterfeiting of silver items. The hammering occurred at room temperature, and, like any cold forming process, caused work hardening of the silver, which become increasingly brittle and difficult to shape. Hammering required more time than all other silver manufacturing processes, and therefore accounted for the majority of labor costs.
