Beaded rims are a characteristic feature of late Roman silver plate vessels, many of which have been found in British treasures including Mildenhall and Traprain Law. This paper discusses how these beaded rims provide insights into the production of silver plate, adding to what little is known of silver plate workshops. Vessels in the Mildenhall treasure provide a case study, after which measurements from beaded rims on other treasures from Roman Britain and the western Roman Empire are compared and discussed.
