Sheffield Assay Office Welcomes The Worshipful Company of World Traders

Published: 10th June 2022

Sheffield Assay Office’s Chairman, Charles Turner, and Assay Master, Ashley Carson were delighted to welcome the The Worshipful Company of World Traders for a tour of our state of the art premises.


They World Traders were visiting Yorkshire and had been welcomed by The Company of Cutlers in Hallamshire earlier in the day. We were so pleased to welcome them to Sheffield Assay Office to learn more about the history and importance of hallmarking today. The group of 50 company members all come from a diverse range of professions and backgrounds in the fields of financial services and trading, including brokers, bankers, accountants and consultants, as well as traders in goods and services and were introduced to the history of Sheffield Assay Office by our Librarian, Archivist and Curator Emma Paragreen.

Our visiting guests were also given a behind the scenes tour of the state of the art facilities by Production Manager, Danny Smith and Quality Manager, Matthew Smith and were delighted to meet with other members of staff along the way, including Jordon Carson and Danielle Ward who demonstrated X-ray Fluorescence (XRF) - a spectrometric technique used to perform elemental analysis.


Master Mary Hardy said; "A huge thank you to all for showing us the workings of the Sheffield Assay Office. Hallmarking is something we all know exists but couldn't really explain how it works - well we can now! We were all fascinated by the process, the technology and the volume of work that passes through the office every day."
