The Full Traditional Mark: Sponsor's mark, Millesimal fineness mark and Assay Office mark. The date letter and the traditional fineness marks are no longer compulsory components of the hallmark. However, we believe that the date letter is a very important component of the hallmark, as it is the easiest way to date an item and research has shown that most of our customers still want to see the traditional fineness mark on the hallmark. Unlike some of the other UK assay offices, we do not charge any extra to apply the two non-compulsory marks.
READING BRITISH SILVER HALLMARKS
The Sterling Silver standard requires all of the metal making up an item to contain parts pure Silver to the When an article of Silver doesn't comply with the required standard the assay offices can and do destroy the object and the Silversmith has some explaining to do. Although it has to be said that most cases are a result of miscalculation.
For example, if the clip of a pen is not made of silver, but the rest of the pen is, then the Assay office would not hallmark the object if by their calculation the whole pen clip an all melted down would not still contain part pure silver. In , a new format of English hallmarking on objects of Sterling Silver was initiated consisting of a maker's mark, the assay office insignia and a symbol.
The standardising of the date letter sequence, shared by all four remaining assay offices in Birmingham, Edinburgh, London and Sheffield, were introduced to bring the UK system closer in line with other European Union standards. The basic method of assaying, also known as the 'Cupellation' process, was first introduced by the ancient Egyptians.
The process starts with a small sample of Silver being removed from the object to be tested, which is then carefully weighed and measured. The sample is placed in a Cupel, a small crucible made of bone ash, along with a small quantity of lead. This is then heated in a furnace. The lead and any other base metals contained in the silver sample are either oxidized or absorbed into the Cupel, leaving only the pure silver behind.
The remains of the silver are then weighed and measured and compared to the initial weight of the sample. The Cupellation process is the most accurate method for determining metal purity and is still the standard technique practiced today - although electronic and chemical tests are now common for small and delicate items. Upon meeting the required standards of Sterling Silver the item of Sterling is stamped with the appropriate hallmark.
Until quite recently, most Hallmarks were 'Struck' using steel punches. The punches are produced in various proportions, appropriate for petite pieces of jewellery to hefty items of Silverware. Punches are made in straight shanks for normal punching with a hammer, or ring shanks used with a press to mark rings. The problem with traditional punching is that the procedure can distort the form of the item being marked, resulting in the article having to be reworked after hallmarking is completed.
For this reason unfinished 'rough' items of are often sent to the assay office where cuts-offs are taken and tested from the articles before hallmarking is executed and the item returned for final polishing. A recently introduced method of marking is uses laser technology, which burns the hallmark into the silver, something which is especially valuable for delicate items which would otherwise be damaged by the traditional technique of punching.
This procedure of hallmarking uses high power lasers to evaporate material from the surface. There are two methods of laser marking, 2D and 3D, 2 dimensional marking burns the outline of the hallmarks into the object, while 3 dimensional marking simulates the traditional punching. The numbers or the word silver seen alone on modern articles for sale proves nothing. This is an international mark called a Convention Mark and may have been put on by the maker in some far flung corner of the globe - it does not mean that the item has been tested by an independent body.

A silver object that is to be sold commercially is, in most countries, stamped with one or more silver hallmarks indicating the purity of the silver, the mark of the manufacturer or silversmith, and other optional markings to indicate date of manufacture and additional information about the piece. In some countries, the testing of silver objects and marking of purity is controlled by a national assayer's office. Hallmarks are applied with a hammer and punch, a process that leaves sharp edges and spurs of metal. Therefore, hallmarking is generally done before the piece goes for its final polishing.
