Birmingham Assay Office
From Wikipedia, the free encyclopedia
The Birmingham Assay Office is one of the four remaining Assay Offices in the United Kingdom.
The development of a silver industry in 18th century Birmingham was hampered by the legal requirement that items of solid silver be assayed, and the nearest Assay Offices were in Chester and London. Matthew Boulton and Birmingham's other great industrialists joined forces with silversmiths of Sheffield to petition Parliament for the establishment of Assay Offices in their respective cities. In spite of determined opposition by London silversmiths, an Act of Parliament was passed in March 1773, just one month after the original petition was presented to Parliament, to allow Birmingham and Sheffield the right to assay silver. The Birmingham Assay Office opened on August 31 1773, and initially operated from three rooms in the Kings Head Inn on New Street employing only four staff and was only operating on a Tuesday. The first customer on that day was Matthew Boulton.
The hallmark of the Birmingham Assay Office is the Anchor, and that of the Sheffield Assay Office was the Crown. A story about the origins of this hallmark go that meetings prior to the inauguration of both Birmingham and Sheffield Assay Offices in 1773 were held at a public house called the Crown and Anchor Tavern on the Strand, London. It is rumoured that the choice of symbol was made on the toss of a coin which resulted in Birmingham winning the Anchor and Sheffield with the Crown (which has now been changed to a rose).
The Birmingham Assay Office moved from the pub in 1815 to its own offices at Little Cannon Street and then moved to its current home in Newhall Street in 1877, and is now the largest Assay Office in Europe, hallmarking 13 million articles in 2003 and claims to be the largest in the world.
Services provided by the office include nickel testing, metal analysis, plating thickness determination, bullion certification, consultancy and gem certification. Platinum was brought within hallmarking regulations in 1975.
