It has been shown (p. [63]) that in 1773 when Sheffield and Birmingham were made Assay towns that silver plate was being made there, contemporaneously with plated wares and presumably by the same firms. The evidence before the Parliamentary Committee in 1773 showed that Sheffield had her silver assayed in London, and that Birmingham had also some of her silver assayed in Chester. It therefore follows that many examples of silver plate bearing the London and Chester hall marks were made at Sheffield and at Birmingham—and in the period from the invention of plated ware at Sheffield by Boulsover till the year 1773.
One of the weakest points in regard to marks on plated ware is undoubtedly the absence of real proof as to date. Similar marks are found covering a period too long for one maker's working lifetime. It follows that they represent firms; often accompanying these, though not always, are signs also found through a long period and on various classes of ware, which are stated to be workmen's marks. In old Worcester china signs not understood and standing apart from the factory mark of the crescent or the square Chinese mark are attributed to workmen. There identity ceases. It is the same, unfortunately, with old Sheffield plate. That the Sheffield platers did attempt to simulate the London marks on silver plate is only too true. In some examples with a row of marks, a very colourable imitation of the leopard's head is seen and the public might well be deceived. But after 1773 this practice became too dangerous. In fact the penalties were so severe that makers feared to mark plated goods until the 1784 Act laid down clearer rules.
The mark consisting of four stamps about 1815 in date is interesting. The casque suggests a head, and the fleur-de-lys might, when worn, suggest the Sheffield crown on silver plate. The G has all the appearance of a date letter. Such marks have a somewhat sinister appearance, as they undoubtedly by their number and character were attempting to simulate the hall marks on silver plate.
In regard to Foreign marks on silver plated ware that was produced in the method of old Sheffield, there are examples known to have been made in France and in Russia, and it is believed that they were also made in Holland and in Sweden. The promulgation of the old Pattern Books by Sheffield at the end of the eighteenth century doubtless had an influence on metal workers on the Continent, who were never slow in assimilating new processes, especially when they offered, as did Sheffield, a lessened cost of production and an appearance simulating something finer.
The legal enactments relating to the marking of French plated ware are referred to on p. [209].
The illustrations of marks found on French silver plated articles are interesting. The authorities were strict in regard to an exact definition in the mark to denote to the public the exact nature of the ware offered for sale. In contradistinction to the slovenliness of English marking this exhibits the logical and protective system devised under French laws. The articles had to be stamped Doublé (replica) or Plaqué (plated), and as is shown in the illustration in no illegible manner. There was no simulation of the French silver plate marks allowed, and the quantity of silver was duly stamped 10M or 20M, as the case might be. The maker, as will be seen, had his mark, but it took a subsidiary place. The public had to be protected first.
In regard to Close Plating, which as a process came about the beginning of the nineteenth century, and was applied to smaller articles where the rolled sheets were not applicable, there are a number of marks found on forks and spoons, snuffers and skewers, on spurs and buckles, dessert knives and forks, and other articles of a like nature.
Electro-plating was discovered about 1840, and a patent was taken out by George and Henry Elkington of Birmingham at that date.
The electro-plated marks are imposing. In worn examples the row of five stamps is not decipherable. What they were originally it is not easy to say, but they have been designed to appear more important than they are.
