According to a legend , King Hiero II was concerned that a gold wreath crown he had purchased was not made of the highest quality gold. In fact, he believed it had been mixed with silver. The King requested the mathematician Archimedes develop a way to determine whether the wreath was pure gold or not. Archimedes was in his bath when he realized that displacement of water hydrostatic weighing was the answer to this riddle. The revelation resulted in Archimedes running through the streets shouting, “Eureka,” which means, “I have found it. That is where the guild members would have their gold work inspected and marked for purity by The Worshipful Company of Goldsmiths. Among the earlier stamps was a leopard’s head. Next, came the maker’s mark , which distinguished one artisan from the next; according to The Birmingham Assay Office , letters were introduced once literacy increased.

Below is an example of the marks of a pewterer who used four of these five types of marks touch mark, hallmark, quality mark and a label. However, it is not complete as many more marks have been recorded since it was written, and some of the information in the book is now known to be incorrect. In London and Edinburgh pewterers had to record their touch marks on special plates, and we know the names of most of those who did so. However, that practice was not followed elsewhere, and so whilst thousands of touch marks have been recorded, we do not always know the pewterers to whom they belong.
Touch marks vary considerably in style and size. If a touch mark includes a date, this is the date on which the pewterer set up in business, not the date on which the article was made. Pseudo-hallmarks When brand new and highly polished, pewter looks very much like silver, and many pewterers stamped pseudo-hallmarks on their wares to mimic the hallmarks on silver.
There are normally four hallmarks, but pewterers from Wigan often used five, whilst very occasionally other pewterers used just three. Sometimes all four hallmarks are the same. Quality marks The crowned rose was used on pewter from the mid 16th century to denote quality. Most pewterers had their own variation of the design.
Later, pewterers also used a crowned X to indicate that the metal was of a certain standard, but by the 18th century all control over the use of the mark was lost and pewterers were using it indiscriminately. Before the introduction of the crowned rose, a crowned or uncrowned hammer was sometimes struck on sadware and this is also believed to be a quality mark.

Distinguishment[ edit ] Hallmarks are often confused with “trademarks” or “maker’s marks”.

The brassy patina suggests that the piece has once been silver plated and unfortunatly due to the wrong type of cleaning the silver has worn off.

Silver cased watch from Birmingham Nice old English lever watch Eric. I’ve read in old books that English watchmakers differed from Swiss and U. S watchmakers in the way that they counted their jewels. An English watchmaker would call your watch ‘jewelled two holes’ and it would be instantly known that your watch has 7 jewels, this is because all English lever watches have two pallet stones, a roller pin ‘jewel’ and endstones to the balance as a matter of course and it was deemed unnecessary to state this detail as it was well understood.
When the pallet staff, escape wheel, 3rd and 4th wheels were jewelled then the watch had four pairs extra or ‘ten holes jewelled’, a Swiss watch jewelled the same would be termed fifteen jewels. If in addition the escape wheel and pallet staff are fitted with endstones then the Swiss and U. S would call such a watch 19 jewels but an English watch would be called ‘ten holes, two end pieces’. This old English watchmaking terminology is all but dead now and most would say ‘thank goodness for that’.

The original aim of the system remains unchanged; the protection of the public against fraud and of the trader against unfair competition. Indeed, hallmarking is one of the oldest forms of consumer protection. Hallmarking is as necessary today as it was in because when jewellery and silverware are manufactured, precious metals are not used in their pure form, as they are too soft.

Sheffield Plate is a cheaper substitute for sterling, produced by fusing sheets of silver to the top and bottom of a sheet of copper or base metal. This ‘silver sandwich’ was then worked into finished pieces. At first it was only put on one side and later was on top and bottom. Modern electroplating was invented by Italian chemist Luigi V. Brugnatelli used his colleague Alessandro Volta’s invention of five years earlier, the voltaic pile, to facilitate the first electrodeposition.
Unfortunately, Brugnatelli’s inventions were repressed by the French Academy of Sciences and did not become used in general industry for the following thirty years. Silver plate or electroplate is formed when a thin layer of pure or sterling silver is deposited electrolytically on the surface of a base metal. By , scientists in Britain and Russia had independently devised metal deposition processes similar to Brugnatelli’s for the copper electroplating of printing press plates.
Soon after, John Wright of Birmingham, England, discovered that potassium cyanide was a suitable electrolyte for gold and silver electroplating. Wright’s associates, George Elkington and Henry Elkington were awarded the first patents for electroplating in These two then founded the electroplating industry in Birmingham England from where it spread around the world.
